TH E ftoppage of fuch hemorrhages as have been cccafioned by the princi- pal operations of Surgery, has in all ages em- ployed the attention of thofe who have been concerned in the various branches of medicine. Fungous fobftances were certain- ly ufed by the ancients j bat they laboured under thefe difadvantages, the circulation of the blood w^as then unknown, and the ufc of the tourniquet undifcovered. They had recourfe to the aftual and potential cautery, and fomc of them in amputations divided B the [2] the * flefli with a red hot knife, in order to fupprefs, or rather to prevent the efFufion of blood. Styptics, and aftrlngents of all kinds, were alfo applied -, but the infufficiency of thefe applications, added to the cruelty of fome of them, and the bad ftate in which the flumps were frequently left by lofs of fubftance, made all other methods give way to the ligature, either with, or without the needle. We are indebted to Ambrofe Parcy for this difcovery. — At firft he thoughthimfelf divinely infpired, and freely communicated his invention ^ but, being vi- rulently attacked by his cotemporaries, he attempted to prove in his defence, that his method had been in pradiceamongft the an- cients, and in vain endeavoured to take away from himfelf the reputation to which he was fo juftly intitled. His improvement was however eftabli(hed, and for more than half a century was looked upon, in every part of Europe where Surgery was cultiva- ted, as the moft fucccfsful way to flop the * Vefalius Chirurg.

This method has indeed fince his time received fome few alterations, particularly that of fubftituting the crooked needle for a ftraight one. For tho' Parey ufed a crooked needle in the fewing of deep wounds, yet he always made ufe of a ftraight one in applying the ligature to the veffels, in fuch cafes as rendered the arterial forceps inejflfedual. Great inconveniences have notwithftand- ing attended this method : in amputation it is allowed, from the tefl:imony of many who have undergone the operation, to be the moft painful part of it, and " * it fometimes hap- " pens in a large ftump,that ten or more vef- " fels require tying." Convulfive fymptoms, the locked jaw, and even death -f- itfelf, have been its followers. It has alfo fre- quently been found infufficient, either when the parts have been lacerated and contufed, or when the extremities of the veffels have been fituated beyond the reach * Sharp*s Surgery, p. 218.

A cafe of this lafl: nature happened to the Marquis of Rothehn * after the amputation of his thigh, and gave rife to a very ingenious contrivance of M. Petit, His inftrument, v^hich was fixed upon the end of the flumps, made a conftant com- preffion upon the veffel, faved the Mar- iquis's life, and gained the greateft honour to the inventor. There have been alfo machines invented by M. Sottere f and M. Belloque, for the ftoppage of blood by compreffion, after the divifions of the intercoflal arteries ; and by M. Foucou + for the fupprefiion of vio- lent haemorrhages, occafioned by extradions of the teeth. Pyramidal comprefles have been fre- quently ufed with fuccefs, and are certainly • Mem.

But though perhaps there are not many arteries in which a ftoppage may not be ef- fedtcd by compreffion when applied with a due degree of care and judgment, and that too without the inconveniences which at- tend the other methods ; yet the nicety | which is required to determine the exadt degree ; the danger * of making too tight the circular . bandage in amputations ; the length of time often required for the continuance of the compreffion, the difficulty of getting at the wound without tightening the tourniquet upon every dref- fing, and the hazard to which the patient is expofed from the poffibility of the comprefles being removed by any trivial accident, are fuch objedions as have hitherto prevented this praftice from coming into general ufe. The difadvantages attending thefe feveral modes of operation, made it the general * Medical Effays,Edin, yol, iv.

Broffard, who received a very confiderablc reward from his mod Chriftian Majcfty for his introdudlion of the agaric of the oak in- to pradice. The moft fanguine wiflies feemed now to be gratified, and the difco- very was embraced by moft Surgeons with the greateft avidity. However, mature experience and repeat- ed obfervations have convinced us, that agaric is in many cafes infufRcient ; and that fome times where it feemed to have been fucccfsful, that fuccefs was as mtich to be attributed to the compreffion ufed, as to the virtues of the plant itfelf. Befides, on account of the little fecurity of retaining it upon the mouths of the divided veffels, it was very difagreeable to praftitioners to depend upon it, without its being watched with the greateft care and affiduity. Ano- ther difficulty too arofe, which was that of procuring at all times the proper agaric ; for as Mr. Warner * has juftly remarked, the * Cafes in Surgery, p. 356. cak i7] oak produces two different kinds. The one has the appearance of foft leather, with apile upon it fomething like that of velvet : the other is thick, rough, and hard; and there is yet another fungous fubftance frequently imported, and ufed for the agaric, which appears to be the fame with that defcribed by Bregnius under the title oifu?2gus coria- cius quercinus Hcemaiodes, I have ufed all thefe^ if I am not greatly miftaken, and ia my opinion the laft mentioned fubftance is much to be preferred to the agaric itfelf. The lycoperdon and fungus vinofus have been alfo applied ; but all thefe applications arc now difcarded in divifions of the lar- ger arteries, and Surgeons find themfelves again obliged to have recourfe to the needle and ligature, notwithflanding its in- conveniences. There is how^ever another remedy,which I think a duty incumbent upon me to lay before the public ; one which as, far as I have obferved, is not liable to any of the objec- tions above recited, which is perfedly fafe and eafy in its application, and in its effefts more certain than even the ligature itfelf. This [8] This remedy is nothing more than the lii- fide of frefh and thoroughly dried fpunge. I would not here be underftood to mean^ that I arrogate to myfelf the merit of being thefirft, by whom fpunge has been apphed in the ftoppage of hemorrhages. I am fenfible that I am not. Spunge was in ufe amongft the ancients, and they feldom if ever applied it medicinally upon any other occafions* We are told by Diofcorides, that new fpunge conglutinates wounds and fiftulous ulcers, and flops the efFufion of blood. The afhes of burnt fpunge were alfo ufed externally. Galen recommends them as powerful rcftringents, and tells us, that one of his mafters often applied, and always carried fpunge about him, which as occafion ferved he burnt with pitch, and frequently ufed hot as a cautery or cauftic to flop haemorrhages after his operations in furgery. Amongft the moderns. Dale*, in his Pharmacologia, fays, that fpunges are feldom if ever ufed internally, but frequently by Sur- geons to flop bleedings. * Page 36. Millar f 9] Miller"^, in his Bot. Offic. tells us, that they are ufed by Surgeons in embrocations, and to flop bleedings- and I muft not omit what Mr. Reid of Chelfea has reported to the Royal Society, that Mr. Chefelden, after an operation for the ftone in the year 174 1-2, put into the wound, which bled too freely, a thin piece of wet fpunge for it to bleed through, and that, contrary to his expefta- tions, it prevented a further lofs of blood. To thefe let me add, that Mr. f Morand nightly t " At the clofe of the year 175 1, an experiment " was made oh dogs with the agaric of oak, which hid <* already ferved for the fame purpofe, after having waih- *' ed and dried it afrefh, aifo with the agaric of beech, of *' birch, of the powder of lycoperdon, fuilainedby fome " pieces of its fpungy part, with thefe fame pieces alone, «« with the common touchwood, with little pieces of " fimple fpunge very fine. The refult of all thefe trials '* was, that the agaric of oak which had already been ufed, ^* did not fucceed fo well as the frefti agaric ; that the other ** agarics, the powder as well as the fpungy part of the '* lycoperdon and the common touchwood, had all pretty •* nearly the fame eiFe£l ; though thefe different prepara- ** tions not being fecuredby compr^ffion, all failed; that *« the common fpunge appeared at firft to produce the •* fame effect, but fell off with the reft. The detail of ** thefe experiments is to be found in a periodical work C '' pqjit^i [ ,o ] flightly mentions fome experiments made with fpunges and other fungous fubftances upon dogs. I cannot however any where difcover, that fpunge alone was ever ufed after the divifions of the larger arteries in the manner I do. Boerhaave enumerates fcventeen forts of Ipunges: The fpunge which I ufeis clofe, compact, and flightly porous ; it generally goes by the name of the male or line fpunge. Iffl am notmiftaken, he has dif- tinguiilied it in his Indt Att. Plant.* by the title of fpongiay ad ufum prajianti/jima^ fo-^ raminibus exiguis pervia^ Tcurn, ^y^.

Care ought however to be taken, that it be placed at fo great a diftance from the fire, when it is fet to dry, as to prevent its crifping : and it ought afterwards to be kept in as dry a place as poffible. I have ufed the outiide of undried fpunges upon fmall arteries with fuccefs ; in thefe cafes it may do full as well, as it may be taken off the wound more eafily : but then it is necefTary to obferve, that, in proportion as you leflen its adhefive quality, you di- minifh its power upon the veffels. It is this property, which gives it fo much merit : from hence arifes its fuperiority to the agraic. It is the texture of its parts, and not any ftyptic or aftringent virtue, from whence it derives its value. f " A pound of fpunge, when weighed in a humid fea- ^* fon, on drying carefully in a ilove without injuring its " texture, will be reduced to eleven ounces.'* Chanu Suppl. art.

C 3 The [ 12 ] The part which nature takes In the. ftop- page of blood, has been imagined by M. Petit and his followers, to be by a coagulum or clot of blood formed in the extremity of the artery, extending itfelf four, five or fix inches up it, in the refemblance of a cone, with its bafe towards the part where the divifions was made. Petit has * delineated the figure of one of thefe little clots, from an artery which he opened after death ^ but it is moft probable that the coagulum was only formed at that time, his hypothefes be- ing liable to many objedions*f*. M.Pouteau has offered a much more probable conjec- ture; his opinion is, that the fwelling of the cellular membrane, which furrounds the artery, brings the fides of the veflfel into contadt, and by that means prevents the blood from efcaping. He opened feveral arteries in which no coagula were found, and where they were difcovered, they ap- peared only to have been formed like po- lypuflfes at, or after death. * Mem.

CASE I, An Account of the good EffeBs of the Spunge^ where the Needle and Ligature could not be made ufe off, and other Applications were found ineffeBuaL MR. Afhton, of Caftleton in Der- byfliire, a ftrong healthful man, about thirty years of age, came over to Manchefter, to confult me about a fcirrhous tumor, that had been for fome years grow- ing under the maxilla inferior upon the right fide, and in which he had lately per- ceived 'fome darting pains, which, toge- ther with the increafe of the tumor, had fome what alarmed him. I advifed him to have it diffeded out ; he confented * " For as foon (fays he) as the ligature is made, the «* cellular fubftance beyond the ftitch, having ilill a ** communication with the. furrounding cells, fwells and " turns^ harder and firmer, fo as to prevent the thread " from^fiidihg." to [14] to the operation, and I performed it, in the beginning of Odober 1760, in the pre- fence of two young gentlemen n:iy pupils. After cutting through the integuments, I drew out the tumor with my differing hook, and extirpated it. In performing this, there was a very con- fiderable branch of the external carotid ar- tery opened. It was fituated fo far under the maxilla in the bottom of the cavity, where the tumor had lain, that I found it impoffible to turn the crooked needle in the wound. I enlarged the incifion with my knife, and made a fecond attempt to take up the veffel with no better fuccefs. I in- effedually applied lint dipped in flower, fe- vera! kind of flyptics, agaric of the oak, and ftrong compreffion. But I muft remark, that it was that kind of agaric which is thick, rough and hard, my ftock of the other being quite exhaufted. Noneofthefe applications fucceeding, I was put upon the difcovery of a proper fubftitute for the foft agaric ; and dry fpunge, appearing to me to have the greateft refemblance, I ftufFed the wound quite full of it. I held it faft for [ '5 1 for a few minutes with my fingers -, after fome time the dreffings were laid on, and a comprefs was applied with a tightifti bandage. Not one drop of blood iffued out from the wound after the application of the fpunge: on the fourth, and every fuc- ceeding day, I renewed the dreffing, letting the fpunge remain, as I found it v/ould not come off without fome little violence, till the loth, when I removed it, and at the fame time made an obfervation, which ex- plained to me the manner of its acting in the ftoppage of blood. I obferved that it adhered intimately to the cellular mem- brane, and flefliy fibres, with which it was fo much interwoven, as almofl to have the . appearance of one body. This rendered it impoffible that the leaft drop of blood fhould efcape; and the reafon of it appeared evi- dent. The fpunge being perfedlly dry • when applied to the wound, and kept on by a moderately tight bandage, introduces itfelf by its foftnefs and elafticity between the fibres of the flefli and cellular membrane, which are themfelves infinuated into the porous- parts of the fpunge. The fpunge thus [16 ] thus receiving and being received, is expand- ed by the moifture of the part, whence it becomes wedged fo faft, as not to be torn away without force. The cohefion every moment grows more flrong, till the fpunge is fully expanded, and caufes fuch a compref- lion upon the fides of the veffel, as to bring them into contact, and render the efcape of the blood impoflible. If the torrent of blood therefore can but be reftrained till thefe efFeds are produced, either by pref- fure upon the fpunge, or by the ufe of the tourniquet, where that can be properly ap- plied, there v/ill be no danger of an hae- morrhage even after the divifions of the largeft arteries ; and fhould the bandage and dreffings by any accident be diiplaced, the fpunge will in a litde time be found to have fecured its own fituation. I muft here obferve, that though the wound was quite filled with fpunge, and though it re- remained ten days in that fituation, I never faw one in a better condition than this was in at the expiration of that time. Ic was as thoroughly digefted as if the mod powerful digeftives had been made ufe of. The The fpunge was fully fatiirated with the matter. The wound, though a deep one, in about a month was filled up with new flefli, and perfed:Iy healed, by which I was fatisfied that its cure was not in the leaft impeded by the application. It was not long before I had repeated op- portunities of obferving the effeits of the fpunge in haemorrhages proceeding from the fmaller arteries, occafioned by the opening of abcefles, by accidental wounds in different parts of the body, by the extirpations of tumors of various forts, and by the exci- £on of fcirrhufes and cancers in the breaft. I likewife applied it to the lefTer veffels af- ter feveral amputations of the larger extre- mities, taking up however with the needle one or two of the principal arteries. For as the character of this remedy was not yet fufRciently cflabliflied, I was careful how I proceeded, and therefore never ven- tured it alone, after the principal amputa- tions, till the loth of Auguft 1761, when after taking off a leg it perfectly fucceeded, D CASE [ i8 ] CASE III. jin Account of the fiiccefsfid Application of the Spunge^ on the 2otb Day after Am- putation^ in a Cafe where the Needle and Ligature had been made ife offy and proved, infuficient. "^HoQias Taylor, of Billinge, near Wigan, in this county, aged 50^ v/as admitted into the Manchefter Infir- inary on the j 2th of January 1761, for fome bad ulcers in his right-hand, which were attended with a caries of moiil of the carpal bones, and of the inferior extremities of the ulna and radius. Thefe complaints had been of many years (landing, and the abforption of the matter had brought on heftic heats, a bad cough, and noctur- nal fweats. Under thefe prefiing circum- flances, it was thought neceflary, at a con- fultation, to take off his hand in order to preferve his life. On the 1 5th of the fame month, I performed the operation a little above its articulation v/ith the radius and ulna. [ 19 ] ulna. After taking up the arteries with the needle and ligature, the flump was dreffed with dry iint and flour, covered with pledgits fpread with yellow bafilicon, and fecured upon the part by a proper ban- dage. Nothing remarkable happened till the 14th day, when a fudden and profufe hemorrhage came on from the cubital ar- tery, which was immediately taken up by a pupil in the houfe, but barft out again the next day, and was again fecured by the needle and ligature. The day after that, upon another eruption, the agaric of the oak, Roman vitriol, and alum, were fepa- rately applied, ftrong compreffion was made ufe of, and the bark was given in great quantities. Not one of thefe had the de- fired efFed. He ftill continued to bleed in a greater or lefs degree till the morning of the 20th day after the operation • when he had loil fo much blood (notwithftanding the greateft care had been taken to re- ftrain it, as often as it appeared, by the tourniquet, which from frequent ufe was obliged to be fixed in different places to prevent its galling) that what came from D 2 I him [20] him was fo thin, as fcarcely to retain either colour or confiftence, and the linen he made ufe of, was, when dry, but juft tin- ged here and there with red. In thefe de- plorable circumflances I applied the fpunge, and over it the ufual dreffing ^ but as all the parts contiguous were in a ragged rot- ten fituation, as well from the frequent re- petition of the needle, as from the bad con- dition of his body, I judged it neceflary to make a ftronger compreffion than ufual on the part. I therefore applied a fcrew in- ftrument, fomething fimilar to that which M. Petit contrived for the Marquis of Rothelin, to the end of the flump, over the dreffing and bandage. In the afternoon I was again fent for, and found him bleeding very fall: : he had fain- ted away, and had fo much the appearance of a corpfe, that I thought he would have expired immediately. Upon uncovering the wound, I perceived that the inftrument had been of great differvice, not having a fufficient fufface to aft upon. This was occafioned by the pointednefs of the flump, which had been reduced by the repeated ufe [21] ufe of the needle and other applications. I was not however without hopes of faccefs, if I could keep my patient alive a little longer. A frefh piece of dry fpungc was placed over the mouth of the veflel, and upon that a quantity of lint to increafe the furface. I retained thefe faft by four crofs flips of good flicking plaifter, and thefe again were fecured by a roller. To make a compreffion upon the end of the flump, I fixed the fcrew inflrument oyer all, with its flraps brought up above the elbow, and there faftened as well as poffible by a ban- dage, obferving at the fame time to keep the arm bent ; and I continued for fome minutes Freke's tourniquet tight upon the upper part of the humerus. A few hours afterwards I flackened the fcrew upon the end of the flump, the bleeding had entire- ly ceafed, and never afterwards returned. At the end of three days I removed the drefiings, and found that the fpunge had fo far fecured itfelf in its fituation, as not to be removed without confiderable violence. Fearing a renewal of the haemorrhage, I fuffered it to remain between five and fix weeks [ 22 ] weeks upon the wound : In which time granulations of flefti had fhot up into the pores of the fpunge 3 and the difficulty of its removal was fo great, that I was obliged to feparate but a fmall portion of it every day, which I cut away with my fcif- fars, till the whole was extirpated. The difficulty I here met with, has ever fince obliged me to guard againft this inconve- nience, by removing the fpunge after it has remained ten, twelve, or fourteen days upon the wound -, and if I have any apprehen- lion of a new eruption, I apply frefii fpunge, which I find much better than the continuance of the firft application. • Perhaps it may be faid, that the com- preffion I made ufe of would alone have flopped the bsemorrhage. — Very poffibly it might ', but then the compreffion muft have been continued for feveral we^k?, which by the affiftance of the fpunge was rendered totally unnecefiary. CASE [ -~3 ] CASE IV. An Account of the Application of the Spiinge with Succefs^ after an accidental Wound in the Leg, AS Orlando Hague, of Afhton Under- line, aged 48, was getting peat up- on the 8th of June 1761, he had the mif- fortune to ftrike his turf-fpade into the in- fide of his leg, about the middle of it, and open the artery called tibialis poflica. A torrent of blood inftantly fucceeding, he had the prefence of mind to lie his handkerchief very tight about his leg, which probably faved his life, as by that means he reftraintd the hsemorrhage a little, though he could not fiop it entirelve His friends immediately brought him to Man- chefter, which is five or fix miles from the place where he received the hurt, he con- tinuing to bleed all the way. I fixed thetourniquet above his knee; and, after I had fufficiently cleanfed the wound from grumous blood, applied dry fpunge, and [24] and over that the ufual dreffings, retained by a moderately tight roller. I then loofened the tourniquet; and though he wasdircd:ly carried up to the Infirmary, which is a quarter of a mile diftant from the houfe where I applied the fpunge, not the leaft effufion of blood fucceeded. The fpunge was removed in about a week after the accident ; he remained in the Infirmary till the 22d of the fame month, when, after being made an out-parient, he returned home, and on the 27th of July was difcharged, perfeftly cured. CASE V. An Account of an Amputation of the Leg below the Knee^ where the Spiinge was ap- plied with Succefs. William Slater, of Knott Lanes, in the parifli of Afhton, aged 24, of a very fcrophulous habit of body, had for fome years been troubled with white fwellings in his ancle, which at laft gather- ed and broke. The inferior extremities of the [25 3 the tibia and fibula, and fome of the tarfal bones being carious; Upon the ad- miffion of the air, his pain increafed greatly, and the abforption of the mat- ter brought on hedical fymptoms, a bad cough, and colliquative fweats. Amputa- tion was the only chance to fave his life, and I performed the operation on the loth of Auguft 1 761, in the prefence of one of my pupils, and of feveral other perfons. After fawing through the bones, the tourniquet being flackqned, the ar- teries tibialis antica, poflica, and peronea, bled very freely. I again tightened the tourniquet, wiped the flump with a fpunge preffed out of warm water, and deanfed it from grumous blood. Three pieces of dry fpunge were now applied to the extre- mities of the veffels, over them the com- mon dreffings, and thefe were retained by a roller, put on rio tighter than juft to keep the fpunge in contad: with the ends of the arteries.— He w-as put to bed, and the tour- niquet kept tight for fifteen minutes, after which 1 flackened it entirely, and had no further occafion to repeat its ufe. He was E remark- [ 26 3 remarkably eafy after the operation, much more fo than I had ever obferved any pa- tient after the ufe of the needle and liga- ture. He flept well all night without the affiftance of any opiate, and no fymptomatic fever enfued. Upon the fourth day I re- moved the dreffings, and found that the fpunge adhered very clofely. The wound was drefTed every day, and at every dreffing a little lint put under the fides of the fpunges, to make them feparate more eafily. On the 3 0th day I removed one piece of fpunge, and on the i2th the other two, en- tire, with the greateft facility, and without the leaft hemorrhage enfuing. The ftump looked remarkably well, was as thoroughly digefted where the pieces of fpunge had lain, as if the moft powerful digeilivcs had been applied, and continued to mend v;ith- out interruption. However, his other fymp- toms grev/ daily worfe, he was quite tired cut with taking medicines, and evidently appeared to be in the laft ftage of a con- fumption. The ftump being now almoft en- tirely healed, my longer attendance became unneceflary. I therefore difcontinued my vifits. [27] vifits about the latter end of Oflober, and have been fince informed that he is dead. CASE VI. An Account oftheSuccefs of the Sptmge after the lateral Operation for the Sto7ie, CD. aged 69, having been troubled ^ with the ftone in his bladder for fome years, came over to Manchefter in Auguft laft, in order to be cut. I performed the operation on the 27th of the fame month, in the prefence of Dr. Nathan Alcock, Fel- low of the Royal Society, and of the col- lege of Phyficians, of my father Dr. Thomas White, Licentiate of the college of Phvfi- ciansin London, and member of the Royal Academy of Surgery at Paris, and of feveral other gentlemen, when a large ftone was extradled. My patient ftruggled much ; which, added to the heat of the weather, made him bleed very freely from an artery upon the proftate gland. I tried the effe.'t of lint dipped in vitriol water ; but that not fuc- ceeding, I introduced a piece of dry fpunge, E 2 to [28] to which I had tied a thread, In order to ex- tract it whenever it (hould be found necef- fary. This flopped the bleeding. In about two hours the urine ran out of the wound, (through the fpunge) perhaps with lefs difficulty than if no fpunge had been made ufe off; for it fometimes happens, that the water does not make its exit fo freely as could be wifhed. In a few days I began to feparate the fpunge from the fides of the wound with my fingers. Upon the 8th day I introduced an hollow cane, whofe diameter was about tv^^o-thirds of an inch, and by the help of the thread drew the end of the fpunge into it ; then thrufting the cane gently forward with one hand, and drawing the thread with the other, I pulled it more and more till the whole was fepa- ratedj not the leafl haemorrhage enfued, and he returned home cured in about nine weeks after the operation.

An Account of the fuccefsful life of the Spunge after an Amputation of the Hand, J Ames Berry, of Worfley, in this county, aged 20, a ftrong healthful man, of a fanguine conftitution, had the misfortune to have his hand greatly fhattered by the fall of a ftone, as he was working at the canal belonging to his Grace the Duke of Bridge- water. The accident happened about nine o'clock in the morning of the 5th of Sep- tember 3761, and he was brought to the Infirmary that day about noon. He com- plained of great pain, which extended itfelf up into his fhoulder 3 he was very hot, and his pulfe full and quick. At a confultation, amputation was thought neceflary, and I took off the hand at its articulation with the radius and ulna about twx) o'clock in the afternoon, in the prefence of Mr. James Burchall and Mr. Edward Hall, Surgeons to the Infirmary, of Mr. Nathaniel Poole the Apothecary, and of feveral other gentle- men. [ 30 j inene Upon my flackening the tourniquet, the radical and cubital arteries fpouted out ; I tightened it again for about fifteen mi- nutes v/hilfl: I applied the fpunge, and ufual dreffings, and fecured them by a roller, when it was entirely loofened without the leaft ejfrufion of blood fucceeding. The heat and pain in his arm llill continuing, I ordered him about feven o'clock in the evening to lofe fiixteen ounces of blood, and to take an opiate ; which, together with nitre, and a little opening phyfic, in a few days removed thefe fymptoms. One of the fpunges was taken away without any difficulty upon the feventh, and the other upon the ninth day after the operation. The wound had a very good appearance, was thoroughly digefted, and every thing went on extremely well till the i6th day, when he began to perceive a little forenefs in his throat, a ftifFnefs in his lovi^er jaw, and a pain in his fore-arm. Thefe complaints, which he attributed to a cold, were fo very trifling, that he did not acquaint any perfon with them till the 19th after the accident, when it plainly appeared that he was affec- ted [3i] ted by that terrible fymptom of a diforder called a locked jaw. As this fymptom could- not poffibly be occafioned by the fpunge, the particulars are foreign to my intention ; it is fufficient to obferve, that, after many medicines had been tried, particularly opi- ates rn great quantities,, both externally and internally, without the lead fign of am.end- mentj he w^as perfecflly cured by frequent repetitions of warm bathing, which was agreed to at a confiiltation upon my pro- pofal. I was induced to try this remedy by the good efFefe which I had formerly ex- perienced from it at the clofe of a diforder of the fame nature, an account of which the gentlemen of the Medical b'ociety in Lon- don have done me the honour to publifli, in the fecond volume of their Obfervations and Inquiries. In which cafe, however, the warm bath was only made ufeof, to re- move that ftifFnefs and univerfal rigidity which remained after the removal of the diforder ^ but in this it was evident that the locked jaw, and other fpafmodic and con- vulfive fymptoms, were abfolutely removed by the help of the bath alone. He was dif- [ 32 ] difcharged on the 7th of December with a good ftump, and without the leaft difagree- able fymptom remaining. CASE VIIL An Account of the fuccefsful Application of the Spunge, after an Amputation of the Fore-Arm. ALice Horradge, of Harwood, aged 44, had been for fome years troubled with ulcers in the fore-arm, attended with a caries of the carpal bones, and of the lower extremities of the radius and ulna. After having been unfuccefsfuUy treated by feveral perfons, fhe came into the Infir- mary, in order to have her arm taken off; and I performed the operation in the mid- dle of the fore-arm on the 2d of November 1 76 1, in the prefence of Dr. Peter Main- wearing, Dr. Samuel Kay, and of Dr. Philip Brown, Phylicians to the Infirmary, of Dr. John Lloyd, F. R. S. and of feveral young gentlemen. Upon loofening the tourni- quet, the radial and cubital arteries, to- gether [33 ] gether with the fmallcr branches bled {icQ" ]y. I tightened it again, and dried the flump with a fpunge prefTed oat of warm water. I applied pieces of frefh dry fpunge to the extremities of the veiTels, and over them the ulual dreffings, retained by a linen roller, fome turns of which w^ere brought above the elbow of the tightnefs ufual after amputations. At the expiration of a quarter of an hour the tourniquet was flackened, without any efFufion of blood. She was remarkably eafy after the operation, and no fymptomatic fever enfued. Upon the 8th day I rem.oved the fpunge which lay upon the cubital artery. This occafi- oned the velTel to bleed again, but with a very fmall contrafted ftream. I ftopped this eruption with my thumb, till a frefli piece of fpunge could be got ready, upon the application of which the hemorrhage inftantly ceafed, without m,y being obliged to have any recourfe to the tourniquet. Up- on the loth I took away the other fpunge without any inconvenience, and I removed that which w^as laft applied upon the 14th, w^ithout the leaf!: effufion of blood. The F wound [34] wound was as fine and frefh as poffible, it continued to mend without interruption, except in one fmall fpot, where a piece of fpunge about the bignefs of a pin's head had been left -, this I exped:ed would have digefted away of itfelf, but finding it would not, I touched it with fpiiit. vi- triol, fort, which entirely took it av^ay. She was difcharged cured, January 25, 1762. CASE IX. An Account of an Operation for the radical Cure of the Hydrocele^ in which the Spunge was fuccejsfully applied. Robert Fletcher, of Little Levir, in this county, aged 47, was admitted into the Manchefter Infirmary, and fell un- der my care. He had on the right-fide an hydrocele of the tunica vaginalis teftis, and on the left not only an hydrocele of the fame tunic, but alfo of the tunica vaginalis of the fpermatic cord, which extended up above the rings of the abdominal mufcles. ■ , The [35] The feptum between the two hydroceles of the left-fide was broke, and the unfortunate patient laboured under more pain on that fide, than I ever knew to proceed from this diforder. I pundlured both fides with my lancet, and let off the water y but in a few weeks they were filled again, and his pain returned. As he was prevented fol- lowing his bufinefs, which was the only maintenance of his family, and was con- tinually in torture, he was defirous oi un- dergoing any thing that might free him froni his diforder, and I confented to the operations on both fides, for the radical cure, on the ift of December 1761. Thefe I performed nearly afrer Mr. Douglas's me- thod by the excifion of the cyfts, but with- out removing any of the lldn, as he had not any to fpare. He bore thefe painful opera- tions with the greateft fortitude and pati- ence. There was no haemorrhage of con- fequent:e, except from the fcrotal artery upon his right-fide. To this I applied a piece of dry fpunge, and held it on with my fingers about a minute, which perfediy flopped the bleeding ; over the fpunge I F z placed [ 36 ] . placed the common dreffings, and retained them on 'by a bag«trufs. At thefe opera- tions were prefent Dr. Kay, and ieveral young gentlemen. My patient told me in the afternoon, that he had more eafe than he had for fome weeks felt. He refled •pretty well at night, without the affiftance of any opiate, and very little of a fympto- matic fever enfued. On the 8th day I re- moved the fpunge without any hsemor- rhage. He continued to mend without in- terruption, and was difcharged cured upon the nth of January 1762. CASE X. In which the Spunge was applied with Sue- cefs below the Knee after Amputation. J Ames Oats, aged 1 5, was admitted in- to the Infirmary, for ulcers in the ancle, attended with a caries: Amputation was refolved upon at a confultation, and I per- formed the operation upon the ift of De- cember 176 1, about noon, in the prefence of Mr, Poole ths Apothecary, and of feve- ral [ 37 ] ral young gentlemen, apprentices or pupils to the Surgeons of the charity. After I had taken off the lin:ib, I applied the fpunge to the arteries, and kept the tourniquet tight for about fifteen minutes, when I loofened it without the enfual of any hemorrhage. The patient was very reftlefs and'ungovern- able, and about feven o'clock pulled up the ftump, in which he had fome twitchings, with fuch a jerk from the pillow as occali- onedit to bleed. The tourniquet was im- mediately applied, and I was fent for by an afliftant whom I had left in the room. The fpunge which I had made ufe of was un- dried, juft as it came out of the Apotheca- ry's {hop, neither was it of fo good a fort as I could have wifhed, a great part of what was in the houfe having been wet and damaged in the carriage. For thefe reafons I thought it proper to apply fome frefh fpunge, which I had brought with me, and upon which I could have a greater depen- dance. The hemorrhage was from the tibialis antica, and as the mouth of the vef- fel had receded, I was appreheniive that the interoiTeal ligament, along the fide of which [ 38 ] which the artery runs, might from its rc- fiftance prevent the fpunge's coming pro- perly into contaft. I therefore cut into the ligament about one third of an inch with fciflars, and after ckanfing the flump from blood, and drying it with a fpunge, I appli- ed dry fpunge, not only to the extremities of the vefTels, but even covered the greateft part of the wound with it, in order to pre- vent any trouble from the fmall capillary vefiels. I loofened the tourniquet in about a quarter of an hour, and gave my patient an opiate in order to keep him quiet. He did not bleed one drop after this, was per- fectly eafy, and flept well all night. He had no occafion for the repetition of the opiate, and had litde or no fymptomatic fever. I removed fome of the fpunges up- on the loth day after the operation, but did not take away the reft till the 14th, when they all came off entire, except one w^hich lay upon the tibialis poftica. This as I was attempting to remove it, tore, and part of it was left behind. The accident was owing to the fpunge*s not being cut tranfverfely, as it ought to have been ^ [39 ] been ; and as the other pieces were but according to the lay, which cccafioned the laft ftratum of the fpunge to be left be- hind, I (hould have found fome difficulty in removing this ilratum, if I had not hit upon an expedient which eafily made it fe- parate. This was by touching it with the butter of antimony, which, tlio' a very ftrong cauftic, occafioned little or no pain, as there was not fo much ufed as would af- feft the flump fo far as to make an efchar, but only jufi: fuch a quantity as would ef- fect my purpofe* I am confident this acci- dent will never happen, if the fpunge be cut properly, and be not of a ragged rotten fort. But if, from any miftake, this fhould ever be the cafe again, I would adyife the application of either of butter of antimony to the fpunge, or of that flrong fpirit of vi- triolj which is improperly called oil of vi- triol. For if any part of the fpunge fhould remain, it would be productive of nearly the fame, tho* perhaps of not quite fuch bad confequences, as arife from the leaving a ftitch behind. Granulations of the flefh would be apt to flioot up and cover it, as they [40] they fometimes do a flitch, and would pro- bably retard the healing of the ftump. I would not be underftood to mean that I would touch ,the ftump itfelf with any po- tent cauftic. I would only apply it to the fpunge. For if a liquid cauftic be made ufe of, it will run through its pores, and thereby bring on a feparation. My patient continued to mend without interruption, is now ftrong and healthy, and his ftump near healed. C AS E XL Of an Ampitation of the Brcafi^ where the Spunge ivas applied with Euccefs. AB. of Manchefter, aged 60, confult- ^ ed me upon account of a cancer of a very quick growth, in her right breaft. Though file had not had any complaints for more than fix or feven months, it had already begun to ulcerate, but was not ad- herent. I advifed her to have the breaft taken off, which ftie confented to, and I performed the operation upon the 5th of December 1761, about two o'clock in the after- [ 41 ] i30bn, in the prefenceof three young gentle-* men my pupils. The wound bled more freely than ever I had feen one of the fame nature, not only from a large artery, but from its whole furface, which was far from being fmalL I wiped it as dry as pbffiblei after which I applied a piece of fpunge to the mouth of the large veffel^ and lint and flower to the rcflc of the wound j but it con- tinued to bleed fo faftj that I was obligedi to remove the lint^ and cover the whole with fpunge : my fpunge was juft as it came out of the fadler's {hop, and as it was a wet day, had imbibed fo great a quantity of moifture from the air, that I was afraid it would not anfwer. Accordingly fom© blood did ou2se through it. I therefore laid fever^l pieces of fpunge before the fire^ to dry, and as I was called away to another pa- tient, left diredtions with Mr. Starkie, my apprentice, to remove the fpunges which had already been applied, provided the wound fliould continue to bleed, and to apply thofe which I had laid to dry. This he ac- cordingly did abouthalf an hour after. The haemorrhage inftandy ceafed^ and never af- G terwarda [ 4Z 1 tgrwards returned. From hence appears the Beceffity of having the fpunges fufficiently dried, the fame fpunge when moift pro- ving infufficient. Five or fix pieces of ^unge were applied. They not only co- vered the whole furface of the wound, but even part of fome of them lay under its lips. Her breaft was eafy after the operar tion, and fhe had no fymptomatic fever* By degrees I loofened the fpunges, and re- moved them one by one, till the laft was taken away upon tbe 14th day after the amputation ; though the wound had been wholly covered, I never faw one in a better ftate, or more thoroughly digefted, and it was perfedly healed in about fix weeks af- ter the operation. This cafe gave me more than ufual trouble j but I had before made fuccefsful ufc of the fpunge, after the amputation of a lady's breaft from Blackrod, upon the 2yth of Oftober 1760, without the occurrence (©f any vexatious accidents e A&E [43 3 CASE XII. jin Account of an Amputation above ths Knee, after which the Spunge was applied with Succef to the Crural Artery, A Lice Watfon, of Manchefter, aged 12, was admitted in the Infirmary, upon the 7th of December 1761. She had been received as a patient about ten months before, for a white fwelling in her knee. I then advifed her to hav.e the limb taken off; but upon her refufing to confent, Ihe was removed by her friends. She was, however, now brought with a great defire of fubmitting to the operation, but was much altered for the worfc. The burfal ligament was fo confumed, that there was aperfed diflocation of the joint. Several finuous ulcers run up the thigh. The dif- charge was, very great, heftic heats were daily confuming her, and fhe v/as fo ema- ciated as to be reduced to the greateft ex- tremity. At a confutation of the Phyfici- ans and Surgeons of the Infirmary, amputa- G 2 - tion [ 44 3 tion was agreed upon, as her only, though but a wretched chance. I performed the operation in the middle of the thigh, upon the 1 6th of December 1761, in the pre- fence of Dr. James Walker, late Phyfician to the Infirmary, and of feveral other gen- tlemen. Upon ilackening the tourniquet the femoral artery bled freely. I tightened the tourniquet again, and after drying the ftump with a fpunge prefled out of warm water, I applied a cubical piece of fpunge, whofe diameter was about an inch, to the mouth of the velTel ; and to prevent any col- lateral branches from being troublefome, I placed a whole undried fpunge over the other, upon the furface of the flump, fe- cured by four crofs flips of good flicking plaifters. Thefe I put ®n not only to keep the fpunges in contacfl, but alfo to prevent the Ikin from receding too much. By de- grees I flackened the tourniquet, and in lefs than half an hour after the fpunges were applied, I entirely loofened it. Upon the 8th day I took ofFthe crofs flips of plainer ^nd the upper fpunge, and upon the 12th removed the fpunge which lay upon the femoral [ 45 } femoral artery. No hasmorrhagc enfued, and the wound was perfectly digefted. She is conftantly attended by Dr. Brown, who prefcribes fuch medicines as are mod likely to recover her health, but, as the amputation was deferred by much too long, with very little profped of fuccefs. It . is now feven weeks lince the operation was performed, the patient is alive, and the (lump near healed. C A S E XIII. An Account of an Amputation of the Great Toe^ and part of the Foot, where the Spunge ivas ufed with Succefs, without having Recourfe to the Tourniquet, MAry Shephard, of Rochdale, aged 20, an inn-patient of the Infirmary, was troubled with a fpina ventofa of the in- ferior extremity of the firft bone of the me- tatarfus. On the i6th of January 1762, I took off" the great toe, together with the ineferior extremity of the metatar- fal bone to which it is joined. An ar- tery bled freely. A piece of dry fpungc was [46 3 applied, and over it the ufual drefling, retain- ed by a roller juft tight enough to keep the fpunge in contacS with the veflel. This impfiediately flopped the haemorrhage, not- withftanding the tourniquet was neither ufed during the time of, nor after the ope- ration. The fpunge was removed upon the yth day without any hasmorrhage enfuing. CASE XIV. An Account of an Amputation of the Leg below the Knee^ after which the Spunge was applied with Succefs. J Ames Perclval, of Manchefter, about 8 years of age, was brought to the In-i firmary, in order to have his leg taken off, for a caries in the ancle joint. I performed the operation in the morning of the 26th of January 1762, in the ufua! place below the knee. Immediately after the amputation I cut upwards into the intejroileous ligament about ope third of an inch, I eafily dif- cpyered the principal arteries v/ithout flac- kening the tourniquet^ and applied pieces of [ 47 1 dry fpunge to the mouths of the veflels, over them a fmall whole fpunge undried, retained by four crofs flips of good flicking plaifter ; upon thefe I placed pledgits of tow fpread with yellow bafilicon, and then fecured the whole by the bandages com- monly made ufe of in fuch cafes, put on with the ufual degree of tightnefs. I flackened the tourniquet in about eight or ten minutes after the application of the fpunge, without any hasmorrhage enfiiing. The patient did not lofe a fpoonful of blood. In about an hour hQ took a quarter of an ounce of the fyrup of poppies, was perfcdl- ly eafy, and flept moft of the afternoon. Dr. Brown and feveral other gentlemen were prefent. As he was a little reftlefs, about midnight he took another quarter of an ounce of the fyrup of poppies. After this he reflcd perfectly well, was free from pain- in the morning, and had fcarcely any fymp- tomatic fever. On the 5tb day I took off the crofs flips? of flicking plaifter and the upper fpunge. On the 8th I removed that fpunge which. lay upon the peroneal artery,, and opoa tho [48 ] the loth day after the operation I took away the other two whole and entire, with- out the leaft hasmorrhage enfuing. The fpunge has never yet failed me^ though I have applied it within thefe fix- teen months to upwards of fifty patients, and have conftantly ufed it fines lafl: Mid- fummer, without ever having had recourfe to the needle and ligature, except in two inftances. In thefe cafes I made ufe of the ligature, not becaufe I thought the fpunge was infufficient, but becaufe 1 apprehended it would be more convenient. My patients were two perfons afflided with the ftone, a boy from Wakefield, whom I cut in the Infirmary, upon the 7th of Odober 1761 ; the other a gentleman from Hali- fax, who underwent the operation about the middle of the fame month. In both thefe cafes an artery was opened at the be-. ginning of the operation, and it appearing moft.prudential to fecure the veffel before I introduced the gorget, I chofe this method of doing it, as that which would be liable to the few^d incoavenienccs. From [49] From the obfervations which I have Inade, I am at prefent of opinion, that if the fpunge be ufed according to the rules which I have laid down, and which I fhall again recapitulate, it is preferable to any other method, and will always prove fuc- cefsful, except in fome few capital cafes> where the tourniquet cannot be made ufe of; as after the amputation of an arm at the fcapula, an operation which fo feldom occurs, as hardly to deferve the name of an exception, but in which, whenever it does, the needle and ligature will certainly deferve the preference, as well as in fuch cafes in lithotomy as are limilar to thofe above-men- tioned • but on the arteries which lie upon the prollate gland the fpunge will have the advantage, as thofe veflels cannot eafily be come at by the needle: I fhall not be afhamed to retradl anr thing I have advanced, if I fhall hereafter find that I have been too fanguine in my expedations. But I thought it better to publifh the few cafes which have already prefented themfelves, than to wait for more, as by this means other proficients will be H more [ 50 ] more eafily induced to make trial of the fpunge, and, I firmly believe, to eftablifli its reputation. It has already been fuccefsful- ly applied by feveral Surgeons in fmallcr cafes upon my recommendation. But I have not yet heard that it has been entirely relied upon by any perfon, except myfelf, after amputations of the larger extremities, cr in any of the capital operations. 1 have not applied any ftrong compreffions to the ends of the ftumps after any of the amputa- tionsj where the fpunge has been made ufe of, except in the cafe of Thomas Taylor, upon whom, as the reader will remember^ the needle and ligature proved ineffedual. It has not even been found neceffary for an affiflant to make any prefTure, as is frequent- ly pradifed with the palms of his hands. But if powerful ccmpreflions fliould here- after appear expedient upon the ftumps of patients of fanguine conftitutions, no da- mage will enfue, provided the circular ban- dages are not too much tightenedj and even in thefe cafes the fpunge will claim the preference over the needle and ligature. Whenever a ftrong compreffion is found necefliry [51 ] neceffary after amputation, either above the knee or above the elbow, it will bed: be made by a fcrew-inftrument, fixed to the end of the flump, and properly fecured by bandages. In both thefe cafes, thefe ftraps muft be brought up over the (houlders ; but after amputations, either below the elbow, or the knee, fufficient prefTure may be made by the double-headed bandage, in the man- ner defcribed by M. Pouteau, in his Me- langes de Chirurgie, p. 355. Thefe flrong com.preffions will but fel- dom be found neceffary where the tourni- quet-ligature is made ufe of. If it jfliould appear otherwife, it will not be requifite to continue them longer than a fingle night, as the fpunge will by that time have fecured itfelf fo effeclually, as not to ftand in need of any affiftance. Dr. Stork * has affirmed that it is of per- nicious, and often indeed of fatal confe- quence, to cover the whole wound wath agaric. In regard to the fpunge, the dired: contrary is true. I have frequently covered * hihellus fecundus, p. 135. H 2 the [ 52 ] the whole wound with it, and, if I am nol tpo much prejudiced in its favour to judge .impartially, have always found that a wound looks clearer and freflier after this^ than after any other application. The rules, of which I would recommend the obfervance, are the follov^ing. To chufe fuch fpunges as are clofe, corn- pad, and not ragged. Either to keep thern dry in fome place near the fire, or to dry them moderately before the fire, but not to fuch a degree as to deftroy their power of expanfion. As fpunges grow from roots Jlratum fuper Jiratum^ they fhould not be cut horizontally, in fuch a rnanner as to fe- parate the lays, but perpendicularly through the lays, fo that every layer may be cut through. Before the application of the dried fpunge, the wound mufi: be cleared from grumous blood, and wiped as clean as pofiible with a fpunge prepared out of warm water. If the divided artery be large, the infide of dry fpunge, cut to the moft convenient fi?e. [53 ] fize,mufl: be applied ; and after amputations, or other wounds where the tourniquet can be made ufe of, that inftrument fhould be kept tight during the time of cleaniing the wound, of applying the fpungc, and for ten, fifteen or twenty minutes afterwards. The tourniquet which I would recommend is the fcrew one, either that of Frcke or Petit ; both of which, as they do not totally pre- vent the circulations being carried on in the fmall collateral branches, are preferable to the common tourniquet-ligature. I would alfo advife the placing of a bolfter upon the principal artery, previous to the fixing of the tourniquet, as by that means the tour- niquet will acquire a greater power upon the vefTel with a fmaller degree of tight- nefs. A gentle compreflion mufl be made up- on the fpunge, either with a linen roller, or with crofs flips of good flicking plaifler. If the wound happens to be in a place where the tourniquet cannot advantageouf- ly be ufed, as was the cafe of the firfl pa- tient upon whom I ufed the fpunge, the fpungc mufl be prelTcd tight into the wound, [ 54 ] wound, a comprefs of linen placed over it, and it muft be fecured by fuch a roller as will make a powerful preffurej obferving at the fame time to keep the patient very cool. Upon the fmaller arteries it will be fufficient to ufe the outfide of undried fpunge, retained by a bandage of moderate tightnefs. After amputations below the knee it will be proper to cut through the interoffeal li- gament about one-third of an inch, for the reafons given in Cafe X. If at any time after the application of the fpunge, the wound flhould bleed again, but in no greater quantity than jufl to wet through the dreffings and the roller, very little regard ought to be paid to it, even the tourniquet itfelf fliould not be tightened : For, in fuch a cafe, as the blood may be only venal, the tightening of the tourniquet would probably be the means to increafe it. If the wound fliould bleed afrefh, fo much as to give reafon to fufpedt that the blood proceeds from an artery, the tourniquet fhould be immediately tightened. I would not, however, advife a ftronger compreflion on lS5] on the fpunge j but as it may be fuppofed to be fully faturated with blood, and there- fore unlikely to flop the hemorrhage, I would apply a frefli piece, and retain it by fuch a degree of compreffion as the emer- gency may render necelTary. At every dreffing fmall pieces of lint fhould be placed under the edges of the fpunge, to facilitate its removal; and when it is intended to be taken away, it fhould be done by taking hold of its end, and pulling it off, as you would a common flicking plaifter. The fpunges fhould not be permitted to remain on longer than ten, twelve, or four- teen days at mofl, after their application. If the fmallefl portion of any of them fhould adhere fo clofely to the wound as not to be removed by gentler methods, it ought immediately to be touched with fome liquid cauftic. This cauflic, however, w^ili be unnecefTary where the fpunge is cut according to the direftions given above. Manchefter, February 4, 1762* Boston Medical Library in the Francis A.
