Abstract:
Cyanide toxicity is a fatal condition if not detected and treated in stipulated time. Lack of rapid detection modalities, and nonspecific nature of clinical presentation make the diagnosis more challenging. Cherry red colour of blood might be the only clue sometimes. We present a case of sudden onset altered sensorium which was detected as cyanide poisoning and treated successfully with antidots on the basis of central venous blood colour and corroborative presentation.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
