Morphine and other narcotic analgesics of the opium group (opium, omnopon, heroin, codeine, etc.)
Morphine and other drugs of the opium group have a selective psychotropic (narcotic) and neurotoxic effect.
When toxic doses of these drugs are taken orally or parenterally, a coma develops with a characteristic significant constriction of the pupils and a weakening of their reaction to light, skin hyperemia, muscle hypertonicity, and sometimes clonic-tonic convulsions.
In severe poisoning, breathing disorders and the development of asphyxia are often observed - severe cyanosis of the mucous membranes, dilated pupils, bradycardia, collapse, hypothermia.
In case of severe codeine poisoning, breathing problems are possible while the patient remains conscious, as well as a significant drop in blood pressure.
Treatment:
-
Repeated gastric lavage (even with intravenous morphine), activated charcoal orally, saline laxative. Forced diuresis with blood alkalization, hemosorption.
-
Administration of 3-5 ml of 0.5% nalorphine solution intravenously.
