Comparison of a Bilateral TAP Block and Preperitoneal Instillation of Local Anesthetic for a Total Extraperitoneal (TEP) Repair

June 1, 2018 updated by: Indiana University School of Medicine

Comparison of an Ultrasound Guided Bilateral Transversus Abdominis Plane Block With Dexamethasone and Preperitoneal Instillation of Local Anesthetic With Dexamethasone to a Standard Anesthetic Technique for Analgesic Efficacy and Patient Satisfaction Following a Total Extraperitoneal Bilateral Inguinal Hernia Repair: A Prospective Randomized Single Blinded Study

Comparison of an ultrasound guided bilateral TAP (transversus abdominis plane) block with dexamethasone and preperitoneal instillation of local anesthetic with dexamethasone under direct visualization will be compared it to a standard anesthetic technique (control) following a TEP (total extraperitoneal) bilateral hernia repair. The investigators are hypothesizing that the bilateral TAP block and preperitoneal instillation of local anesthetics with the addition of dexamethasone are superior in terms of patient satisfaction and post-operative pain control when compared to a standard anesthetic technique (no regional technique).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

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

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

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
Assess the efficacy of a bilateral TAP block and preperitoneal instillation of local anesthetic to a standard anesthetic technique for TEP hernia repair
Time Frame: Post-operatively (Day 1)
Assessment will be done postoperatively using a Quality of Recovery 40 (QoR-40) questionnaire after surgery.
Post-operatively (Day 1)

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
Assess the efficacy of a bilateral TAP block and preperitoneal instillation of local anesthetic to a standard anesthetic technique for TEP hernia repair
