Identifying high-risk patients is key for managing postoperative nausea and vomiting (PONV). Current risk scores are unreliable, suggesting aggressive treatment may be more effective than prophylaxis for many patients.

Area of Science:

  • Anesthesiology and pharmacology
  • Clinical risk assessment

Context:

  • Postoperative nausea and vomiting (PONV) is a common complication.
  • The 'rule of three' outlines a three-step approach for optimal PONV management.
  • Accurate identification of high-risk patients is crucial for effective prophylaxis.

Purpose:

  • To evaluate the effectiveness of the 'rule of three' for PONV management.
  • To assess the reliability of current risk-scoring systems for PONV.
  • To determine optimal strategies for PONV prophylaxis versus treatment.

Summary:

  • The 'rule of three' involves identifying high-risk patients, using low-emetogenic anesthesia, and administering prophylactic antiemetics.
  • Commonly used prophylactic antiemetics include butyrophenones, 5-HT(3) receptor antagonists, and steroids.

  • Current risk-scoring systems for PONV exhibit unsatisfactory sensitivity and specificity.
  • The identification of high-risk patients remains the most challenging aspect of PONV prophylaxis.

    • Impact:

    • Improved patient outcomes through targeted PONV management.
    • Potential for cost-effectiveness by optimizing prophylaxis strategies.
    • Highlights the need for more accurate risk prediction tools in clinical practice.
    • Suggests aggressive treatment of established PONV may be more beneficial than prophylaxis for some patients.
