Preoperative fasting guidelines, often recommending "nil by mouth" (NPO) after midnight, lack scientific support. This review examines current international recommendations versus scientific evidence on fasting durations for anesthesia.

Area of Science:

  • Anesthesiology
  • Surgical Safety
  • Clinical Practice Guidelines

Background:

  • Fasting before anesthesia is a standard safety practice.
  • Current guidelines often mandate "nil by mouth" (NPO) for extended periods, frequently after midnight.
  • These prolonged fasting recommendations lack robust scientific evidence.

Purpose of the Study:

  • To review current international preoperative fasting guidelines.
  • To compare these guidelines with recent scientific literature on fasting durations.
  • To identify discrepancies between routine practice and evidence-based recommendations.

Main Methods:

  • Survey of current preoperative fasting recommendations in various countries.
  • Analysis of recent scientific studies, reviews, and editorials on preoperative fasting.

  • Inclusion of opinions from leaders of the World Federation of Societies of Anaesthesiologists (WFSA).

    • Main Results:

    • A potential discrepancy exists between scientific findings and current clinical practice regarding preoperative fasting.
    • Recent literature emphasizes a need to re-evaluate fixed fasting durations.
    • International recommendations may not fully align with the latest evidence.

    Conclusions:

    • Current "nil by mouth" (NPO) guidelines for preoperative fasting may be outdated and not fully evidence-based.
    • Further alignment of clinical practice with scientific research on fasting durations is warranted.
    • Revisiting and updating international guidelines is crucial for optimizing patient safety and comfort.
