Abstract

Opiate intoxication accounts for the majority of emergencies related to substance abuse. The concomitant intravenous and intramuscular administration of the specific narcotic antagonist naloxone is warranted in such cases. Further threatening complications of opiate abuse include rhabdomyolysis, noncardiogenic pulmonary edema, and both peripheral and central nervous lesions. Opiate abuse is often associated with benzodiazepine abuse. Hence, intravenous administration of the antagonist flumazenil is indicated in patients with suspected acute opiate intoxication resistant to naloxone. Cocaine abuse is not frequent in this country but is usually very severe and clinically heterogeneous. The clinical pattern of cocaine intoxication is initially due to excitatory and later to depressant effects on central nervous, circulatory and respiratory systems. The treatment of acute cocaine intoxication is symptomatic. The internal concealment of cocaine and other drugs in packets (body-packing) may lead to bowel obstruction or to acute intoxication following leaking or breaking of packets.
