Liquid Mosquito Repellent Ingestion in Children

Hydrocarbons are a common cause of accidental poisoning in children, with kerosene being the most implicated agent in rural parts of India. However, lately, liquid mosquito repellent ingestion is emerging as an important cause of hydrocarbon (kerosene) poisoning in urban households.
This is a retrospective case series over a 5-y period (January 2013 – December 2017) of children with accidental liquid mosquito repellent ingestion presenting to the pediatric emergency. Epidemiology, clinical profile, management and outcomes are discussed.
Twenty-three children with median (IQR) age of 24 (18.8–32) mo presented after mean (SD) interval of 6 (3) h from ingestion. Majority (20, 87%) were seen during summer months (March–June) and all were from urban background. Sixteen (70%) had mild-moderate acute respiratory distress syndrome (ARDS) requiring supplemental oxygen with or without positive airway pressure for a mean (SD) duration of 3.3 (1.9) d. All except one survived.
Children with accidental liquid mosquito repellent ingestion had predominant aspiration pneumonitis due to hydrocarbon content rather than neurological complications attributable to synthetic pyrethroids. Ensuring child-proof containers, appropriate storage, regulatory surveillance and parental awareness are must for prevention.
