Summary

Routine gastric aspiration after anesthesia does not significantly reduce postoperative nausea and vomiting (PONV) in women undergoing abdominal hysterectomy. This finding suggests current practices may not impact emesis incidence or severity.

Area of Science:

  • Anesthesiology
  • Gastroenterology
  • Surgical Care

Background:

  • Postoperative nausea and vomiting (PONV) is a common complication following general anesthesia.
  • Gastric aspiration is sometimes performed at the end of anesthesia to prevent PONV.
  • The efficacy of gastric aspiration in preventing PONV after abdominal hysterectomy is not well-established.

Purpose of the Study:

  • To investigate the effect of gastric aspiration on the incidence and severity of postoperative emesis.
  • To determine if routine gastric aspiration is beneficial in patients undergoing elective abdominal hysterectomy.

Main Methods:

  • A randomized controlled trial involving 201 women undergoing elective abdominal hysterectomy.
  • Patients were anesthetized with isoflurane, nitrous oxide, and oxygen.

  • Half of the patients underwent gastric aspiration at the end of anesthesia; the other half did not.

    • Main Results:

    • The overall incidence of emesis within 24 hours post-operation was similar between groups (79% with aspiration vs. 70% without).
    • No significant difference in the incidence or severity of emesis was observed at any time point during the 24-hour postoperative period.
    • Gastric aspiration did not appear to influence the occurrence or intensity of postoperative emesis.

    Conclusions:

    • Gastric aspiration at the end of anesthesia has no major impact on the incidence or severity of postoperative emesis in patients undergoing abdominal hysterectomy.
    • These findings suggest that routine gastric aspiration may not be a necessary intervention for preventing PONV in this patient population.
    • Further research could explore alternative strategies for PONV prophylaxis in abdominal hysterectomy patients.
