Strychnine poisoning.

Abstract

Strychnine poisoning is an unusual but dramatic poisoning in which convulsions are the major threat to life. Convulsions are predominantly at the spinal level, and the key to recognition of this poisoning is observation of convulsive activity in the awake patient without a postictal phase. Successful treatment requires aggressive airway control and treatment of seizures with benzodiazepines or barbiturates. Neuromuscular blockade may be required. Gastrointestinal decontamination is usually indicated in recent acute ingestions but may precipitate convulsions. Recovery from strychnine poisoning is usually complete and rapid if treatment is aggressive. In the absence of trauma, compartment syndrome, rhabdomyolysis, or anoxic central nervous system injury, no neurologic or musculoskeletal sequelae are expected. Confirmation of strychnine poisoning is best obtained by submitting urine or gastric aspirate for analysis utilizing a qualitative test such as thin layer chromatography (TLC).

London audit of drug-related overdose deaths: characteristics and typology, and implications for prevention and monitoring.

OBJECTIVES: To describe the circumstances and draft a typology of drug-related overdose deaths. SETTING: London, 2003. METHODS: An audit of 148 drug overdose deaths (involving heroin, methadone, dihydrocodeine, cocaine, amphetamine or MDMA) investigated by coroners during 2003. Information extracted on toxicology, pathology and circumstances were used to identify drug(s) implicated in the death. RESULTS: Poly- or multiple drug use was detected in the majority of deaths with at least 69 different combinations, including 66% for heroin and 42% for cocaine. Six categories of death were identified involving an opiate (100, 68%); cocaine (14, 9%); other controlled drug (five, 3%); mixed drug overdose (18, 12%); other prescribed drug (five, 3%); and other causes (seven, 5%). A witness was present and the death was not instantaneous in 92 (61%) cases, although evidence in the coronial file suggested that in the majority of cases the overdose went unnoticed until too late to intervene. In all, 15 (one in 10) of the deceased were released from prison within 3 months of death; and 37 (one in four) were reported as in receipt of a methadone prescription. CONCLUSIONS: Perhaps for the first time in the United Kingdom cocaine was detected in more drug overdose deaths than methadone. However, reducing heroin use is central to the prevention of drug-related deaths. We recommend that overdose prevention encompasses strategies to encourage a 'mutual duty of care' among problem drug users, and in the United Kingdom further investigation of the relationship of methadone treatment failures on overall trends in drug-related deaths is merited.
