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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • ASA I-II,
  • between the age of 18-69,

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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.
Procedure: lumbar epidural analgesia with bupivacaine
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).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
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

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
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
