Summary

Preoperative epidural morphine significantly reduced intraoperative and postoperative opioid needs for major abdominal surgery patients. This approach provided effective pain management for up to three days, lowering overall analgesic requirements.

Area of Science:

  • Anesthesiology
  • Pain Management
  • Pharmacology

Background:

  • Effective pain management is crucial for patients undergoing major intra-abdominal surgery.
  • Opioid analgesics are commonly used but associated with significant side effects.
  • Optimizing perioperative pain control can improve patient outcomes.

Purpose of the Study:

  • To evaluate the efficacy of preoperative epidural morphine combined with general anesthesia (GA) for managing pain.
  • To assess the impact on intraoperative and postoperative analgesic requirements over a 3-day period.
  • To compare pain scores between patients receiving epidural morphine and those receiving standard care.

Main Methods:

  • Prospective, double-blind, randomized study involving 20 patients undergoing major intra-abdominal surgery.

  • Two groups: control (n=10) and epidural (n=10) receiving 5 mg epidural morphine before GA.
  • Postoperative pain managed with patient-controlled intravenous (IV) morphine.

    • Main Results:

    • The epidural group showed significantly lower intraoperative fentanyl and cumulative 3-day postoperative morphine requirements compared to the control group.
    • Postoperative pain scores were significantly lower in the epidural group at 24, 36, and 60 hours after surgery.
    • Opioid consumption remained consistently low in the epidural group throughout the 3-day study period.

    Conclusions:

    • A single preoperative epidural injection of 5 mg morphine provides effective intra- and postoperative analgesia for at least 3 days.
    • This method reduces overall opioid consumption and pain intensity following major abdominal surgery.
    • Preoperative epidural morphine is a viable strategy for enhancing perioperative pain management.
