Cartap Hydrochloride Poisoning: Rarely Seen, Rarely Heard.

: 20.3). Notably, serum pseudo-cholinesterase levels and other laboratory findings were within normal limits. The patient was treated with non-invasive ventilation (NIV) for respiratory acidosis and administered a loading dose of N-acetylcysteine (NAC) (150 mg/kg) along with symptomatic management. His sensorium and ABG parameters normalized within six hours of treatment. He remained asymptomatic and was discharged after three days. Human toxicity from CH is rarely reported, and cases involving mixed acidosis are particularly sparse in literature. This case highlights the importance of recognizing CH poisoning, which can mimic organophosphate toxicity. Vigilant monitoring for acidosis via ABG and early intervention with NAC and supportive care, such as NIV, are crucial for successful clinical outcomes.
