November 28, 2022 updated by: Alshaimaa Soliman Alasrag, Tanta University

Analgesic Efficacy of Combined Ultrasound-Guided PECS II and Transeversus Thoracic Plane Blocks Versus Ultrasound-Guided Serratus Anterior Plane Block in Modified Radical Mastectomy: A Prospective Randomized Study

The aim of this study is to evaluate the analgesic efficacy of combined ultrasound (US)-guided pectoral nerve (PECS) block II and transversus thoracic plane (TTP) block versus US-guided serratus anterior plane (SAP) block in female patients undergoing modified radical mastectomy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

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.

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.

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
The total amount rescue analgesic consumption (morphine) in the first 24 hours postoperatively.
Time Frame: First 24 hours postoperatively.
Rescue analgesia in the form of morphine (3mg IV) will be given if the VAS is ≥ 40, repeated with lock out interval of 5 min guided with the occurrence of complications till the VAS is decreased to less than 40.
First 24 hours postoperatively.

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
The degree of postoperative pain
Time Frame: First 24 hours postoperatively.

Postoperative pain will be assessed by Visual Analog scale (VAS) on admission to Post-Anesthesia Care unit (PACU) and at 30 minutes and then 1,2,4,6,12,18 and 24 hours postoperative.

VAS (0-100; where 0 represents no pain and 100 represents the worst pain).
First 24 hours postoperatively.
Time to first rescue analgesia request.
Time Frame: First 24 hours postoperatively.
Rescue analgesia in the form of morphine (3mg IV) will be given if the VAS is ≥ 40, repeated with lock out interval of 5 min guided with the occurrence of complications till the VAS is decreased to less than 40.
First 24 hours postoperatively.
Intraoperative fentanyl consumption.
Time Frame: Intraoperative
Additional boluses of fentanyl 0.5 µg /kg will be administered in case of inadequate analgesia that defined as increase of heart rate (HR) and /or mean arterial blood pressure (MAP) more than 20 % from baseline
Intraoperative

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
