Insights
Reducing the interval between fluid intake and anesthesia to 4 hours appears safe for infants. Studies show that 10% glucose solution is almost completely emptied from the stomach within 4 hours, minimizing anesthetic risks.
Area of Science:
- Pediatric Anesthesiology
- Gastrointestinal Physiology
Context:
- Investigating anesthetic risks associated with reduced fasting intervals in infants.
- Evaluating gastric emptying times following fluid administration before anesthesia.
Purpose:
- To determine if a 4-hour fasting interval post-fluid intake increases anesthetic risks in infants.
- To assess gastric residual volume, pH, and glucose concentration at different time points.
Summary:
- Gastric fluid volume, pH, and glucose were measured in 23 infants 6 hours after normal feeding and 2-4 hours after a 10% glucose solution feed.
- Results indicated near-complete gastric emptying within 4 hours after administering a 10% glucose solution.
Impact:
- Provides evidence to potentially shorten pre-anesthetic fasting guidelines for infants.
- Informs clinical practice regarding fluid management and anesthetic safety in pediatric patients.
Abstract:
The problem was investigated whether a reduction to 4 hours of the interval between fluid intake and start of anaesthesia carried increased anaesthetic risks. In 23 infants the residual volume of gastric fluid, its pH and glucose concentration were determined 6 hours after normal feeding and 2 hours and 4 hours after administration of a 10 per cent glucose solution in quantities equivalent to a normal bottle feed. The results showed almost complete gastric emptying 4 hours after administration of a 10 per cent glucose solution.
