The median duration of pediatric general anesthesia was 57 minutes, with 94% of exposures lasting less than 3 hours, though children under 1 year had longer median exposures (79 minutes).

What is the duration of pediatric general anesthesia exposure in contemporary practice?
The vast majority of pediatric general anesthesia exposures are under 3 hours, but children under 1 year, those with high ASA physical status, and those at university hospitals are at risk for longer exposures.
INTRODUCTION: Understanding the duration of pediatric general anesthesia exposure in contemporary practice is important for identifying groups at risk for long general anesthesia exposures and designing trials examining associations between general anesthesia exposure and neurodevelopmental outcomes. METHODS: We performed a retrospective cohort analysis to estimate pediatric general anesthesia exposure duration during 2010-2015 using the National Anesthesia Clinical Outcomes Registry. RESULTS: A total of 1 548 021 pediatric general anesthetics were included. Median general anesthesia duration was 57 minutes (IQR: 28-86) with 90th percentile 145 minutes. Children aged 3 hours. High ASA physical status and care at a university hospital were associated with longer exposure times. CONCLUSION: While the vast majority (94%) of children undergoing general anesthesia are exposed for <3 hours, certain groups may be at increased risk for longer exposures. These findings may help guide the design of future trials aimed at understanding neurodevelopmental impact of prolonged exposure in these high-risk groups.
Bartels et al. (Wed,) conducted a cohort in Pediatric general anesthesia (n=1,548,021). Pediatric general anesthesia was evaluated on General anesthesia duration. The median duration of pediatric general anesthesia was 57 minutes, with 94% of exposures lasting less than 3 hours, though children under 1 year had longer median exposures (79 minutes).
