Summary

Preoperative fasting is safe for children undergoing minor surgery. Extended fasting times did not lead to hypoglycemia in infants and children, indicating good tolerance.

Area of Science:

  • Pediatric Anesthesiology
  • Pediatric Surgery
  • Clinical Nutrition

Background:

  • Preoperative fasting guidelines aim to prevent aspiration and hypoglycemia.
  • Optimal fasting durations for pediatric patients undergoing elective surgery are debated.
  • Previous studies suggest prolonged fasting may increase risks in infants and children.

Purpose of the Study:

  • To evaluate the safety and tolerance of preoperative starvation in healthy children of different age groups.
  • To assess fasting blood glucose levels in pediatric patients after varying fasting periods.
  • To determine if current preoperative fasting protocols are appropriate for diverse pediatric age groups.

Main Methods:

  • 230 healthy children were divided into four age-based groups: small infants (1-3 months), infants (3-12 months), pre-school children (1-6 years), and older children (>6 years).

  • Children underwent preoperative starvation for durations tailored to their age group (4, 6, or 8 hours).
  • Fasting blood glucose levels were measured preoperatively, with specific attention to prolonged fasting durations (≥12 hours).

    • Main Results:

    • Fasting durations ranged from 6.7 to 12.6 hours across the groups.
    • Fasting blood glucose levels remained above 95 mg% in all groups, with no instances below 40 mg%.
    • Even infants starved for 12 hours or more maintained adequate blood glucose levels.

    Conclusions:

    • Preoperative starvation is well-tolerated in infants and children undergoing elective minor surgery.
    • Current fasting protocols can be safely implemented, even with potential delays in surgical schedules.
    • Extended fasting times do not appear to pose a significant risk of hypoglycemia in this pediatric population.
