Clinical and Demographic Profiles of Children Presenting with Acetaminophen Induced Acute Liver Failure in a Tertiary Paediatric Intensive Care Unit of South India
Introduction: Acetaminophen (APAP) is the most widely used over-the-counter antipyretic and analgesic medicine in children. Although hepatic failure and death is rare in paediatric population, it is one of the most important and dangerous presentation of acetaminophen induced toxicity in children. There is very sparse data regarding APAP induced paediatric acute liver failure in our settings, hence this study was done to know the clinical and demographic profiles as well as outcome of children with APAP induced acute liver failure. Methods: This was a retrospective study done in children aged 0 - 18 years admitted with the diagnosis of acetaminophen induced acute liver failure in a tertiary paediatric intensive care unit of South India from January 2014 to December 2018. The clinical, demographic profiles and outcome of these patients were reviewed and analysed. Results: A total of 26 children had acetaminophen induced acute liver failure. Out of 26 patients, 53.8% were males and 46.1% were females. Among these, 24 (92.3%) survived and two (7.7%) died. The average dose of acetaminophen ingested was 168.5 mg/ kg/d. The mean serum acetaminophen level was 52.3 mg/dl. The presence of low pH, hypotension and international normalised ratio (INR) value of > 4 showed bad outcome in children with acetaminophen induced acute liver failure. Conclusion: Paracetamol induced acute liver failure is rare but fatal presentation in children. Children with acidosis, shock and INR value of > 4 had poor prognosis. Hence, judicious use of different preparations as well as counselling to parents regarding use of appropriate doses in children should be done while prescribing this medicine.
