May 23, 2017 updated by: Dr Anita Kulkarni, Rajiv Gandhi Cancer Institute & Research Center, India

The Analgesic Efficacy of Ultrasound Guided Transversus Abdominis Plane (TAP) Block in Lower Abdominal OncoSurgeries

Effective postoperative pain control results in decreased cardiac and pulmonary complications, patient satisfaction and early mobilization. A prospective, randomized comparative study was done of analgesic efficacy, opioid requirement and side effects in patients undergoing lower abdominal cancer surgeries. In Study Group Ultrasound guided Transversus Abdominis Plane (TAP) block was given and control Group no TAP block was given. Patient controlled analgesia (PCA) with intravenous morphine was given to both group patients, and total good PCA demands in both the groups was studied.

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

Adult patients of both sexes undergoing major lower abdominal cancer surgeries were enrolled in the study. After obtaining written informed consent from all the patients, they were randomly allotted to either Study (TAP) Group or Control group. Standard general anesthesia with endotracheal intubation was performed in all the patients. Preoperatively all patients received information about Visual Analogue Scale (VAS) for Pain Score from 1 to 10 depending on intensity of pain and about the use of Patient Controlled Analgesia (PCA) Pump. After the end of surgery and before extubation bilateral Ultrasound guided Transversus Abdominis Plane (TAP) block was performed with 16 G Tuohy needle and 18 G Braun Perifix epidural catheter was placed about 6-8 cms in situ. Bupivacaine 0.25 % 20 ml was given bilaterally and repeated 8 hourly in the Postoperative Anaesthesia Care Unit (PACU) for first 24 hours. The PCA Pump was set to deliver bolus Intravenous Morphine 1 milligram ( mg ) with lock out interval 10 minutes. In the PACU heart rate, Non invasive blood pressure, Visual Analogue Score at rest and on knee flexion, Sedation score, nausea and vomiting, any side effects as itching was noted by care provider at 0, 2, 4, 6, 12, 18 and 24 hours. Total and good PCA demands upto 24 hours was 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

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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: Transversus Abdominis Plane (TAP) Block Group
Intervention - At the end of surgery Ultrasound guided Transversus Abdominis Plane block was given with 20 ml 0.25 % bupivacaine bolus and repeated every 8 hourly upto 24 hours.
Drug: Bupivacaine (Transversus Abdominis Plane Block)
Intervention - At the end of surgery Ultrasound guided Transversus Abdominis Plane block was given with 20 ml 0.25 % bupivacaine bolus and repeated every 8 hourly up to 24 hours.
Placebo Comparator: Control Group (No TAP Block)
The Transversus Abdominis Plane Block was not performed. Intravenous PCA Morphine was given as rescue analgesic upto 24 hours.
Drug: Intravenous Patient Controlled Analgesia (PCA) Morphine
PCA Intravenous Morphine 1 milligram bolus on demand was given as rescue analgesia up to 24 hours.

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
Visual Analogue Pain Score in PACU in Transversus Abdominis Plane Block and Control Patient Group.
Time Frame: up to 24 hours
In the PACU Visual Analogue Pain Score will be noted at rest and on knee flexion up to 24 hours.
up to 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
Total and Good demands for PCA IV Morphine in milligrams in both the groups.
Time Frame: up to 24 hours
In the PACU, Total and Good PCA IV Morphine demands in milligrams in both groups was studied.
up to 24 hours
