Outcomes of pediatric ingestions of alcohol-based hand sanitizers during the COVID-19 pandemic

Abstract

Introduction In July 2020, an outbreak of methanol-contaminated hand sanitizers in the United States prompted our regional poison center to implement a more conservative triage guideline for hand sanitizer exposures. All pediatric hand sanitizer ingestions of more than a “taste” were referred to a healthcare facility for assessment. We then evaluated the effect of this change on identifying patients with methanol poisoning. Methods This was a single-center, retrospective review of pediatric (<19 years) hand sanitizer ingestions reported to our poison center from May 1, 2020 through January 28, 2022. Methanol and ethanol concentrations were collected if available. Results During the study period, we received 801 calls regarding hand sanitizer exposure, of which 140 children were referred to a healthcare facility for hand sanitizer ingestions. Of those, 88 (63%) had methanol and/or ethanol concentrations measured. No child had a detectable methanol concentration, 78 had ethanol testing, and 12 had a detectable ethanol concentration. Conclusions In this sample, no patient tested had a detectable methanol concentration. Children who consumed enough to have a detectable ethanol concentration were symptomatic or had an intentional ingestion. Asymptomatic children with unintentional ingestion of hand sanitizer were at low risk for methanol toxicity.
