Abstract

A 19 year old male was admitted to a tertiary care centre in Sri Lanka, with a history of snake bite while sleeping at night. A killed specimen of a snake was brought with the patient. It had been identified as a non-venomous snake by the doctor and handed over to relatives, with a comment to that effect. Patient had no clinical or laboratory evidence of envenoming on admission. Patient developed bilateral ptosis six hours after alleged snake bite, soon followed by respiratory paralysis and was treated with Indian polyvalent anti-venom serum. After 12 h of the bite, patient had developed hypotension that did not respond to ionotropes. Despite intensive management, patient had become deeply comatose and deceased 46 h following the snake bite. Autopsy revealed features suggestive of disseminated intravascular coagulation. Since an allegation of medical negligence too had been levelled by the relations of the patient against the clinical staff, the buried specimen of the snake was recovered by police, on a judicial order, a week later. It was found to be almost completely disintegrated and only the scales and bones were remaining. According to the scale characters, the reconstructed specimen was identified as Indian krait (Bungarus caeruleus). Authentication of snake is important in investigating a death due to snake bite, especially when the snake was initially claimed to be a non-venomous snake. This case suggests the usefulness of forensic identification of species of the snake in investigating suspected snake bite cases.
