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.

Detailed Description

Postoperative pain is commonly observed in patients undergoing lumbar microdiscectomy surgery.

To manage this pain, the lumbar erector spinae plane (ESP) block is frequently administered as part of a multimodal analgesia regimen, particularly with the aim of reducing opioid consumption in these patients.

Recent publications have demonstrated the analgesic efficacy of the sacral erector spinae plane block in lumbar microdiscectomy surgeries.

In this study, the postoperative analgesic effectiveness of the lumbar ESP block-performed two vertebral levels above the surgical site-will be compared with that of the sacral ESP block-performed two vertebral levels below the surgical site.

It is anticipated that this approach will provide effective analgesia while avoiding the use of opioids.

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

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
Time Frame
total tramadol consumption
Time Frame: first 24 hours after the surgery
first 24 hours after the 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
patients' visual analog scale
Time Frame: first 24 hours after the surgery
To compare postoperative Visual Analog Scale (VAS) pain scores at 2, 4, 8, 12, and 24 hours.
first 24 hours after the surgery
To compare analgesic consumption during the postoperative time intervals of 0-2, 2-4, 4-8, 8-12, and 12-24 hours.
Time Frame: first 24 hours after the surgery
postoperative 0-2, 2-4, 4-8, 8-12, and 12-24 hours.

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 15, 2025

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
