Estimating pediatric general anesthesia exposure: Quantifying duration and risk

Area of Science:

• Anesthesiology
• Pediatric Medicine
• Neurodevelopmental Research

Background:

• Understanding pediatric general anesthesia duration is crucial for identifying risks and designing neurodevelopmental outcome studies.
• Contemporary data on anesthesia exposure times in children are limited.

Purpose of the Study:

• To estimate the duration of pediatric general anesthesia exposure.
• To identify patient and hospital factors associated with prolonged anesthesia exposure.
• To inform future research on neurodevelopmental outcomes related to anesthesia exposure.

Main Methods:

• Retrospective cohort analysis of pediatric general anesthetics.
• Data sourced from the National Anesthesia Clinical Outcomes Registry (NACOR) between 2010-2015.
• Inclusion of 1,548,021 pediatric general anesthetics.

Main Results:

• Median general anesthesia duration was 57 minutes (IQR: 28-86).
• Children under 1 year experienced the longest median exposure (79 minutes, IQR: 39-119), with 13.7% exposed for over 3 hours.
• Higher ASA physical status and university hospital care were linked to longer anesthesia durations.

Conclusions:

• While 94% of pediatric patients have anesthesia exposure under 3 hours, specific groups are at higher risk for prolonged exposure.
• Findings aid in designing future trials focusing on the neurodevelopmental impact of prolonged anesthesia in at-risk pediatric populations.
