June 4, 2024 updated by: Jokevin Prasetyadhi, Hasanuddin University

Comparison Between Pectoral Nerve Block II and Local Anesthesia Infiltration of Isobaric Bupivacaine 0.25% 50 MG on Neutrophil-Lymphocyte Ratio, Interleukin-6 Levels, Pain Intensity, and Post-surgical Opioid Requirements in Modified Radical Mastectomy Patients

Studied the comparison between PECS II block and LIA on pain intensity, opioid requirements, RNL, and postoperative IL-6 levels in MRM patients.

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

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.
Interventional

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.

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
Concentration of Plasma Interleukin-6
Time Frame: 1 hour before surgery, 2 hour after surgery, 12 hour after surgery
in pg/dL
1 hour before surgery, 2 hour after surgery, 12 hour after surgery
Neutrophil-lymphocyte ratio
Time Frame: 1 hour before surgery, 2 hour after surgery, 12 hour after surgery
Neutrophil divided by lymphocyte
1 hour before surgery, 2 hour after surgery, 12 hour after surgery
Pain intensity (Using Numeric Rating Scale)
Time Frame: hour 0, 2, 4, 6, 12, 24
Scale from 0-10, lower score = better outcome
hour 0, 2, 4, 6, 12, 24
Rescue opioid requirement
Time Frame: Within 24 hours after surgery
Using fentanyl at a dose of 0.5-1 μg/kg/IV titrated as needed, in mcg (given if the patient had NRS of >4/10)
Within 24 hours after surgery

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
Demographic baseline data
Time Frame: baseline (before the surgery)
Medical record number, age, body weight (in kilogram), height (in centimeter), BMI (in kg/m2), ASA PS class, duration of surgery (in minutes)
baseline (before the surgery)
Time until first rescue opioid requirement
Time Frame: Within 24 hours after surgery
in minutes
Within 24 hours after surgery
Nausea and vomiting
Time Frame: Within 24 hours after surgery
Nausea and vomiting were assessed using a numerical scale (0 = no nausea, 1 = mild nausea, 2 = severe nausea or vomiting once, and 3 = vomiting more than once). If the score was > 2, rescue antiemetics with ondansetron 0.1 mg/IV were given.
Within 24 hours after surgery

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.
