ABSTRACT: Green pit viper (Trimeresurus erythrurus) bite is common in Myanmar and only few bites have been reported. Clinical features, venom antigen levels and development of venom antibodies in four green pit viper bites were presented. Pain and local swelling started early after the bite and spread to involve more than half of the bitten limb in 2-3 days and subsided on 5 days after the bite. Incoagulability of blood was observed as early as 1.15 to 2.40 h after the bite. One systemic envenomed case presented with vomiting, abdominal colic, sweating, hypotension and shock. Thrombocytopenia, neutrophilic leucocytosis, anaemia and raised blood urea were present for a week. Initial venom antigen levels ranged from 47 to 103 ng/ml. Antigen clearance depends on "venom hours". The pattern of antibody response following the bite was short lived in nature. Monospecific Russell's viper antivenom has no effect on correcting coagulation defect.
