Fatal Period.—The usual fatal period is one to two hours. In a few cases
death has occurred within five to thirty minutes after swallowing the poison,
and in rare cases death has been delayed six to eighteen hours. If a narcotic
preparation has been taken together with strychnine, death may not occur
for several hours.

Diagnosis.—Strychnine poisoning has to be diagnosed from tetanus. The
chief distinguishing points between the two are as follows : —

STRYCHNINE  POISONING

1.  Onset, sudden.                f r

2.  All the muscles are affected at a time.

3.  During the intervals the muscles are re-
.  laxed.

4.  Death takes place within a few hours,
If death does not occur within four to
six hours, the probability of recovery is
great.

TETANUS

1.  Onset, gradual.

2.  The muscles of the nock and lower jaw
are affected first (Lock-jaw).

3.  During the intervals the muscles are
rigid.

4.  Death rarely takes place within 24 hours
and may be delayed for several days.

Treatment—Give chloroform inhalation to check the spasms, and thep
introduce the stomach tube to wash out the stomach with warm water con-
taining potassium permanganate, animal charcoal, tannic acid or tannin, In
the absence of the tube, evacuate the stomach contents by the hypodermic
administration of 1/10 to 1/5 grain of apomorphine hydi&chloride,, It al$o
tends actually to quiet and prevent the convulsions. Three cases are
reported in which the hypodermic use of apomorphine hydro chloride was
followed by recovery in human beings who had taken presumably lethal
quantities of strychnine.4

Short-acting barbiturates like pentobarbital sodium, sodium amytal and
other barbituric acid derivatives are considered as valuable antidotes to
strychnine, and should be administered immediately intravenously in doses
of 5 to 10 grains dissolved in 10 cc. of distilled water or in sufficient quanti-
ties to induce sleep or to stop convulsions."

Large doses of potassium bromide and chloral hydrate should be given
internally at frequent intervals. Chloral hydrate may be given in 30-grain
doses by the rectum or in 5-grain doses hvpodermically. Urethane (dos.e,
1 to 4 drachms) is considered useful in controlling convulsions. Gentle
narcosis, perfect quiet and dark surroundings are very essential. Nitrite of
amyl and oxygen may be administered by inhalation. Artificial respiration
may be attempted, if respiratory paralysis supervenes.
