COMPARISON of the EFFECT of TWO DIFFERENT ANALGESIS TECHNIQUES in ABDOMINAL HYSTERECTOMY

February 17, 2025 updated by: Emirhan Akarsu, Ataturk Training and Research Hospital

Comparison of the Analgesic Effect of Intrathecal Morphine and Bilateral Transversus Abdominis Plane Block in Patients Undergoing Elective Abdominal Hysterectomy

Hysterectomy is one of the most commonly performed surgical procedures after cesarean section in many countries worldwide, especially among women of reproductive age. Postoperative pain is typically managed with oral and parenteral narcotics. Patient-controlled analgesia (PCA) is an effective pain management method that provides advantages such as faster pain relief, better dosage control, and elimination of the need for timer adjustments. Facilitating the recovery process and optimizing postoperative pain management are crucial components of perioperative care. To minimize systemic opioid requirements and opioid-related side effects, multimodal analgesia combining local anesthesia, peripheral, and non-opioid analgesics has become increasingly popular.

Study Overview

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.

Study Type

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

No

Description

Inclusion Criteria:

  • Women aged between 18 and 65 years classified as ASA 1 and ASA 2.

Exclusion Criteria:

  • Patients with allergies to the active substance, those with severe liver or renal insufficiency, a history of long-term nonsteroidal anti-inflammatory drug (NSAID) and opioid analgesic use, a history of gastrointestinal bleeding, peptic ulcer or inflammatory bowel disease, a history of diabetes or other neuropathic conditions, preoperative atrioventricular block and bradycardia, underlying serious respiratory diseases, a history of psychiatric disorders, patients classified as ASA stage 3 or higher, patients weighing less than 40 kg, patients unable to use the patient-controlled analgesia (PCA) device, and patients who need to discontinue the study medication during surgery for any reason will be excluded from the study

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

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.
Active Comparator: Group Intratechal Morphine
Other: Intratechal Morphine
Prior to induction, the patient will be positioned seated, and morphine will be slowly injected intrathecally at a dose of 5 μg/kg, adjusted to the L4-L5 or L3-L4 intervertebral space using a 27G pencil point spinal needle. The injection will be administered over approximately 10 seconds
Active Comparator: Group Transversalis Fascia Plane Block
Other: Transversalis Fascia Plane Block
Prior to induction, patients will be positioned supine, and bilateral transversus abdominis plane (TAP) block will be performed with the aid of ultrasound. As the blocking agent, 20 cc of 0.25% bupivacaine will be used bilaterally.

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
Postoperatve Opioid Consumption
Time Frame: postoperatively 24 hours
The primary aim of this study is to compare the analgesic efficacy of intrathecal morphine and bilateral transversalis fascia plane block in patients undergoing elective abdominal hysterectomy, in terms of morphine consumption during the first 24 hours postoperatively
postoperatively 24 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
Postoperative Pain Scores at movement and rest
Time Frame: postoperatively 24 hours
evaluation of pain scores during movement and rest within 24 hours postoperatively using Visual Analogue Scale
