Summary

Preoperative metoclopramide, an antiemetic, provided significant postoperative pain relief in laminectomy patients. This reduced the need for additional analgesics compared to ondansetron or placebo.

Area of Science:

  • Anesthesiology
  • Pharmacology
  • Neurosurgery

Background:

  • Antiemetic agents like metoclopramide and ondansetron are sometimes associated with analgesic effects.
  • Previous research suggests metoclopramide may reduce postoperative opioid needs, while ondansetron's analgesic role is debated.

Purpose of the Study:

  • To evaluate the postoperative analgesic efficacy of metoclopramide and ondansetron in patients undergoing laminectomy.
  • To compare pain scores and analgesic requirements between metoclopramide, ondansetron, and placebo groups.

Main Methods:

  • A randomized controlled trial involving 46 laminectomy patients.
  • Patients received intravenous metoclopramide (0.5 mg), ondansetron (0.1 mg), or saline placebo 30 minutes pre-surgery.
  • Pain was assessed using a visual analogue scale (VAS) at multiple time points post-surgery, with diclofenac as rescue analgesia.

Main Results:

  • Lower VAS pain scores were observed in the metoclopramide group compared to ondansetron and control groups (P<.05).
  • Patients in the metoclopramide group required significantly less rescue diclofenac compared to the other two groups (P<.05).

Conclusions:

  • Preoperative administration of metoclopramide demonstrates significant postoperative analgesic properties in laminectomy patients.
  • Metoclopramide may be a valuable adjunct for managing postoperative pain, reducing the need for additional analgesics.
