Operative fasting guidelines and postoperative feeding in paediatric anaesthesia-current concepts

Area of Science:

• Anesthesiology
• Pediatric Medicine
• Clinical Nutrition

Background:

• Preoperative fasting is a critical safety measure to prevent pulmonary aspiration during anesthesia.
• Gastric emptying times vary based on intake type (solids vs. liquids, breast milk vs. formula).

Purpose of the Study:

• To review current guidelines and evidence regarding preoperative fasting periods in pediatric patients.
• To assess the safety and efficacy of updated fasting protocols.

Main Methods:

• Systematic literature search of PUBMED using keywords: child, paediatric, anaesthesia, fasting, preoperative, gastric emptying.
• Hand-searched references from relevant review articles and major society guidelines.

Main Results:

• Leading pediatric anesthesia societies recommend clear fluid intake up to 1 hour before elective surgery.
• Established guidelines suggest 4-hour fasting for breast milk, 6 hours for milk/light meals, and 8 hours for fatty meals.
• ESPEN guidelines indicate oral intake can resume within hours post-surgery, with fluids initiated sooner than solids.

Conclusions:

• Updated guidelines support shorter preoperative fasting periods, particularly for clear fluids, in pediatric patients.
• These revised protocols aim to improve patient comfort and safety while minimizing aspiration risk.
• Further research may refine guidelines for solid food intake post-anesthesia.
