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.

Detailed Description

This is a double-blinded, randomized, controlled trial. Women who undergone elective vaginal hysterectomy and gave their informed consent were included. Exclusion criteria included additional abdominal, chronic pelvic pain, malignancy, and allergy to Bupivacaine.

Solutions of either Bupivacaine-Hydrochloride 0.5%, or Sodium-Chloride 0.9% as a placebo, were prepared prior to surgery, according to randomization. The chosen solution was injected before incision, as a modified paracervical block, and in each resection line (sacro-uterine and cardinal ligaments). The amount of fluid administered was 10 ml. When colporrhaphy was also performed, an additional 5 ml of solution were injected in the midline of the vaginal wall prior to each incision line.

By utilizing the 10 cm Visual-analogue-scale (VAS) we examined the differences in post-operative pain at rest at 3, 8, and 24 hours, and during ambulation at 8 and 24 hours using multivariate linear regression models. We also assessed the differences in analgesics given at the different time points between the groups using multivariate negative binomial regression models.

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 and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

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

ACTIVE_COMPARATOR: Study
Marcaine 0.5 % Injectable Solution will be injected before incision, and in a systematic fashion as a modified paracervical block. First, 2 ml will be injected through the vaginal fornices at 03.00, 06.00, 09.00, and 12.00 hours at 2 cm depth. Thus, 8 ml will be systematically injected around the cervical circumference before incision. In addition, 1 ml of the solution will be injected in each resection line (sacro-uterine and cardinal ligaments), adding up to a total of 10 ml. In case of performing additional anterior/ posterior colporrhaphy, additional solution of Marcaine 0.25%will be prepared: 5 ml of the solution will be injected to the cutting line of the anterior/ posterior vaginal wall, respectively, prior to incision.
Drug: Marcaine 0.5 % Injectable Solution
Local infiltration by Marcaine 0.5% Injectable Solution prior to incision

PLACEBO_COMPARATOR: Control

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
Pain at movement
Time Frame: 24 hours
Movement-evoked pain will be scored after the operation
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
pain at rest
Time Frame: 24 hours
Pain at rest will be scored with the woman lying in bed after the operation
24 hours

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.
