Strychninepoisoning can be fatal to humans and can be introduced to the body by inhalation, swallowing or absorption through eyes or mouth. It produces some of the most dramatic and painful symptoms of any known toxic reaction. For this reason, strychnine poisoning is often used in literature and film.
Ten to twenty minutes after exposure, the body's
muscles begin to spasm, starting with the head and neck. The spasms then spread to every muscle in the body, with nearly continuous convulsions, and get worse at the slightest stimulus. The convulsions progress, increasing in intensity and frequency until the backbone arches continually. Death comes from asphyxiation caused by paralysis of the neural pathways that control breathing, or by exhaustion from the convulsions. The subject will die within 2–3 hours after exposure. At the point of death, the body "freezes" immediately, even in the middle of a convulsion, resulting in instantaneous rigor mortisFact|date=June 2008.
There is no specific antidote for strychnine. Treatment of strychnine poisoning involves an oral application of an activated charcoal infusion which serves to absorb any poison within the digestive tract that has not yet been absorbed into the blood. Anticonvulsants such as
phenobarbitalor diazepamare administered to control convulsions, along with muscle relaxants such as dantroleneto combat muscle rigidity. [ [http://www.portfolio.mvm.ed.ac.uk/studentwebs/session2/group12/strychni.htm Strychnine: ] ] If the patient survives past 24 hours, recovery is probable.
The treatment for strychnine poisoning in the late 19th and early 20th centuries was to administer
tannic acidwhich precipitates the strychnine as an insoluble tannate salt, and then to anaesthetise the patient with chloroformuntil the effects of the strychnine had worn off.
trychnine poisoning in animals
Strychnine poisoning in animals occurs usually from ingestion of baits designed for use against rodents (especially gophers and moles) and
coyotes. Rodent baits are commonly available over-the-counter, but coyote baits are illegal in the United States. However, since 1990 in the United States most baits containing strychnine have been replaced with zinc phosphidebaits.cite book|author=Ettinger, Stephen J.;Feldman, Edward C.|title=Textbook of Veterinary Internal Medicine|edition=4th ed.|publisher=W.B. Saunders Company|year=1995|id=ISBN 0-7216-6795-3] The most common domestic animal to be affected is the dog, either through accidental ingestion or intentional poisoning. An approximate lethal dose for a dog is 0.75 mg per kg body weight.cite web|author=Beasley, V.|year=1999|title=Toxicants Associated with Seizures|work=Veterinary Toxicology|url=http://www.ivis.org/advances/Beasley/Cpt2B/chapter_frm.asp?LA=1#| accessdate=2006-06-18] For a 0.3% strychnine bait, five grams of bait could be enough to kill a 20 kilogram dog.
The onset of symptoms is 10 to 120 minutes after ingestion. Symptoms include
seizures, a " sawhorse" stance, and opisthotonus(rigid extension of all four limbs). Death is usually secondary to respiratory paralysis. Treatment is by detoxification using activated charcoal, pentobarbitalfor the symptoms, and artificial respirationfor apnea.
In most States you need a special license to use and prose Strychnine for agricultural use.
