Background: Acute poisoning is a major public health problem. This retrospective study was done to analyse the
characteristics of acute poisoning cases admitted in a tertiary care hospital in Chennai so as to ensure effective poisoning
prevention and targeted interventions to reduce the mortality and morbidity due to poisoning, as the incidence of poisoning is rising worldwide.
Methodology: This retrospective analysis was done by analysing the poisoning case sheets in the medical records department in a tertiary care
hospital for a duration of 3 months. Data pertaining to patient's demographic details, pattern, manner of poisoning, the mode of ingestion, clinical
prole, severity of poisoning using Poisoning Severity Score, treatment prole and outcome were collected using a pre-structured proforma.
Results: In this study 488 poisoning case sheets were analysed. Most of poisoning cases (40%) occurred in the age group of 21-30 years. 59%
were males. Chemical poisoning 79% was most common among males and tablet poisoning 63% among females. Manner was suicidal in 82%
cases, accidental in 13% and 0.2% was homicidal. The incidence of Rat killer poisoning (33%) was highest followed by tablet poisoning (20%),
Insecticide poisoning (13.5%), Animal poison (13%), Corrosive poisoning (5.7%), Chemical poisoning (4.9%), and Plant poison (2.7%). 5.7%
patients had associated Psychiatric illness and 16% were alcoholic. 74% patients were admitted within 3 hours of poison intake. Gastric lavage,
Activated charcoal, N-Acetylcysteine, Inj. Vitamin K, Ursodeoxycholic acid, Rifaximin, Atropine, Anti-snake Venom, and Pralidoxime were
the treatments given. Of the total 488 patients 94% were discharged, 4% death and 2% left against medical advice. The mean duration of hospital
stay was 4 days.
Conclusion: This study shows that Rodenticide poisoning was most common followed by tablet poisoning which mainly includes
benzodiazepines, thyroid supplements, antiepileptics and antihypertensive agents. The next common was organophosphate poisoning of which
chlorpyrifos and cypermethrin were common. Overall mortality rate was 4% of which Rat killer paste was the most common cause of mortality (
35%) associated with coagulopathy, acute encephalopathy and toxic hepatitis. With proper Counselling, stress management, restricted access to
OTC drugs and insecticides, by ensuring protective measures to avoid exposure and by prompt diagnosis and timely initiation of treatment at the
primary level we can reduce the mortality
