Summary

Preoperative epidural morphine effectively managed pain after esophagectomy. Adding continuous epidural lidocaine during surgery did not further improve postoperative analgesia for these patients.

Area of Science:

  • Anesthesiology
  • Surgical Pain Management
  • Oncology

Background:

  • Esophagectomy is associated with significant postoperative pain.
  • Effective pain management is crucial for recovery after esophagectomy.
  • Epidural analgesia is a common strategy for managing surgical pain.

Purpose of the Study:

  • To evaluate the efficacy of preoperative epidural morphine with a double-catheter technique for postoperative analgesia in esophagectomy patients.
  • To determine if continuous intraoperative epidural lidocaine improves analgesia when combined with preoperative epidural morphine.
  • To compare pain scores in patients receiving epidural morphine plus lidocaine versus epidural morphine plus saline.

Main Methods:

  • A randomized, double-blind, controlled trial involving 30 patients undergoing esophagectomy.

  • Patients received preoperative epidural morphine (2 mg at T6-7 and 2 mg at L3-4) via double catheters.
  • Postoperatively, patients received continuous thoracic epidural infusion of either 1% lidocaine or normal saline.

    • Main Results:

    • Both groups reported adequate pain control, with mean pain at rest below 4 (on a 0-10 scale) and mild pain on deep breathing.
    • No statistically significant differences in pain scores were observed between the lidocaine and control groups.
    • Preoperative epidural morphine provided sufficient analgesia following esophagectomy.

    Conclusions:

    • Preoperative epidural morphine using a double-catheter technique is effective for managing postoperative pain after esophagectomy.
    • The addition of intraoperative continuous epidural lidocaine does not offer additional analgesic benefits in this setting.
    • This approach ensures adequate pain relief for patients undergoing esophagectomy.
