The study, which analyzed 49,588 patients, suggests that language barriers and confusion may contribute to this increased risk.
Most children, including nearly 80% of infants, do not follow recommended guidelines for pre-surgery fasting from clear liquids. Prolonged fasting can be harmful and increase dehydration, pain, anxiety, and nausea. The study suggests allowing healthy children to drink clear liquids up to two hours before surgery.
