Twenty cases of cobra bite in farmers from the central region of Thailand are reported. Ptosis is the earliest sign of cobra bite and is an important diagnostic indication of systemic poisoning. Restlessness, irregular breathing and mental confusion are warning signs of respiratory paralysis. Antivenom for cobra bite was administered intravenously together with symptomatic and supportive treatment; 19 patients survived and 1 died from cerebral anoxia.
