Postoperative Pain Relief After Major Abdominal Gynecological Surgery

May 6, 2024 updated by: Hakki Unlugenc, Cukurova University

Comparison of Lumbar Epidural Analgesia, Transversus Abdominis Plane Block and Wound Infiltration for Postoperative Pain Relief in Major Abdominal Gynecological Surgery

The aim of our study was to compare the effects of Lomber Epidural Analgesia (LEA), Transversus Abdominis Plane (TAP) block and Local Anesthetic Infiltration (LAI) on postoperative morphine consumption, time to first recue analgesic request, pain and patient satisfaction scores and side effects were compared in the patients undergoing major gynecologic/oncology lower abdominal surgery.

Study Overview

Detailed Description

Following faculty ethical committee approval and written informed consent, 81 patients were included in our prospective, randomized and double-blind study. Patients were divided into 3 groups: lumbar epidural block (Group E), TAP block (Group T), and wound infiltration (Group I). Demographic data, surgical characteristics, hemodynamic values, pain scores at rest and on movement, morphine consumption, additional analgesic requirement, side effects at 1, 2, 6, 12, 24, 36 and 48th hours after surgery, and patient satisfaction scores at 24 and 48th hours were recorded.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: lumbar epidural analgesia with bupivacaine
For postoperative analgesia; Lumbar epidural catheter inserted at L3-4 or L4-5 epidural space before anesthesia induction in the sitting position. After the end of surgery but approximately 20 minutes before extubation, 0.125% bupivacaine 20 ml administered through epidural catheter and the catheter was removed.
postoperative analgesic method
Active Comparator: transversus abdominis plane block with bupivacaine
For postoperative analgesia; After the end of surgery but before extubation, USD-guided TAP block was performed with 0.125% bupivacaine 20 ml to the anatomic neurofacial space between the internal oblique and transersus abdominis muscles, bilaterally (10 ml for each side).
postoperative analgesic method
Active Comparator: wound infiltration with bupivacaine
For postoperative analgesia; After the end of surgery but before extubation, 0.125% bupivacaine 20 ml administered to the surgical incision site.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
morphine consumption
Time Frame: change from baseline morphine comsumption at 48 hours
At the end of the surgery, the patients were allowed to use the patient controlled analgesia device (PCA). The PCA (CADD Legacy PCA pump, Smiths Medical MD, Inc. St. Paul, MN) was prepared with 40 mg morphine HCl in 100 ml saline. The PCA doses of morphine consisted of a bolus dose of 0.02 mg/kg every 15 minutes without a background infusion. Morphine consumption (mg) was evaluated and recorded postoperative 48 hours.
change from baseline morphine comsumption at 48 hours

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
pain scores
Time Frame: change from baseline pain scores at 48 hours
postoperative pain scores of the patients were recorded using visual analog scale (VAS; 0=no pain, 10=worst pain)
change from baseline pain scores at 48 hours
patient satisfaction score
Time Frame: postoperative 24 and 48 hours
patient satisfaction scores were recorded using patient satisfaction scale (0= worst, 10=excellent)
postoperative 24 and 48 hours
time to first rescue analgesic
Time Frame: postoperative 48 hours
If the patients complained of pain despite the analgesia regimen, iv 50 mg meperidine was given as a rescue analgesic.
postoperative 48 hours
side effects
Time Frame: postoperative 48 hours
all patients were visited after surgery in the ward and side effects were evaluated and recorded
postoperative 48 hours
