Fasting before surgery in Germany is being re-evaluated. New evidence suggests clear fluids up to two hours pre-op are safe, reducing patient discomfort without increasing aspiration risk.

Area of Science:

  • Anesthesiology
  • Gastroenterology
  • Surgical Care

Context:

  • Traditional German preoperative fasting guidelines mandate fasting after midnight for elective surgery.
  • This practice aims to mitigate the risk of pulmonary aspiration.
  • Recent scientific evidence challenges the necessity and efficacy of prolonged preoperative fasting.

Purpose:

  • To review the scientific literature on preoperative fasting and gastric emptying.
  • To evaluate the evidence supporting current fasting guidelines in Germany.
  • To propose updated recommendations for preoperative clear fluid intake.

Summary:

  • Experimental and clinical studies demonstrate reliable gastric emptying within 2 hours.
  • Limited intake of clear fluids up to 2 hours preoperatively does not appear to increase patient risk.

  • Pulmonary aspiration incidence is low and often linked to airway protection and anesthetic depth, not fasting duration.

    • Impact:

    • Supports a shift towards more liberal preoperative fasting guidelines.
    • Aims to decrease perioperative patient discomfort.
    • Provides a scientific basis for revising national recommendations on preoperative fluid intake in Germany.
