An observational study of 11 cases of Cartap poisoning-a rare poisoning

Abstract

Objective: Cartap hydrochloride poisoning is an uncommon poisoning encountered in India. The aim of this study was to assess the characteristics, severity, management, and outcome of patients with Cartap poisoning, treated with N-acetylcysteine (NAC) in intensive care unit (ICU) of a tertiary referral hospital. Methods: This is a retrospective study where 11 cases of Cartap poisoning admitted to hospital ICU between 2011 and 2016 were identified from the case records. The demographic data, mode of ingestion, time to treat, ingested dose and severity of poisoning, presenting features, duration of mechanical ventilation (MV), dose of NAC used, complications, and outcome were noted. Results: Patients were scored as moderate or severe cases of poisoning. Severe cases consumed >10 g, underwent gastric lavage > 4 hrs, and took Cartap concomitantly with alcohol or in empty stomach. Duration of MV varied from 68-94 hrs in severe cases and 12-48 hrs in moderate cases. Average dose of NAC in severe case was 11.19 g and moderate case was 8.89 g. The most common presenting symptoms were vomiting, altered sensorium, and breathlessness. Severe cases had more complications, and the most common complication was hypotension followed by seizures. Survival was 100%. Conclusion: 50% of Cartap poisoning cases had good survival outcome. Severity of poisoning depends on amount of Cartap ingested, time taken for gastric lavage, and concomitant administration of alcohol. Duration of MV and dose of NAC and complications encountered correlates with the severity of poisoning.
