Trial summary

In recent years, regional anesthesia techniques have also been frequently applied to patients for pain relief. Erector spinae plane block (ESPB), is among the regional anesthesia techniques frequently used in lumbar spine surgery. General anesthesia (GA) is the main method of anesthesia for lumbar spine surgery. Read more about this study

About this study

Official title: Effect of ESPB on Intraoperative Remifentanil Consumption in Lumbar Spine Surgery

In recent years, regional anesthesia techniques have also been frequently applied to patients for pain relief. Erector spinae plane block (ESPB), is among the regional anesthesia techniques frequently used in lumbar spine surgery.

General anesthesia (GA) is the main method of anesthesia for lumbar spine surgery. However, GA can only inhibit the projection system of the cortical limbic system or hypothalamic cortex. GA cannot completely block the transmission of peripheral noxious stimulus to the central nervous system and cannot effectively inhibit the intraoperative stress response. With the addition of peripheral blocks such as ESPB, lower remifentanil consumption, and more stable hemodynamics are expected by providing preemptive analgesia in patients.

As a result of all these; it was aimed to compare the intraoperative remifentanil consumption of patients who underwent preoperative ESPB in patients who will undergo lumbar spine surgery resection under GA with those who underwent postoperative ESPB.

Being tested
Preoperative Erector Spinae Plane Block, Postoperative Erector Spinae Plane Block

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Preoperative Erector Spinae Plane BlockDrug

    Erector spinae plane block will be performed bilaterally, under US guidance, before the surgical operation, after the induction of anesthesia, and when the patient is placed in the prone position.

  • Postoperative Erector Spinae Plane BlockDrug

    Erector spinae plane block will be performed unilaterally, under US guidance, after the surgical operation, under general anesthesia, and when the patient is placed in the prone position.

Study groupRoleWhat they receive
Preoperative Erector Spinae Plane BlockActive comparatorIn the preoperative period, under general anesthesia, after the linear ultrasound (US) probe will be placed 2-3 cm lateral to the L3 spinous process, 15 ml of 0.25% bupivacaine will be injected into the interfacial space below the erector spinae muscle, above the transverse process. The same ESPB procedure was performed on the other side. In total, 30 ml of 0.25% bupivacaine was administered.
Receives: Drug: Preoperative Erector Spinae Plane Block
Postoperative Erector Spinae Plane BlockActive comparatorIn the postoperative period, under general anesthesia, after the linear ultrasound (US) probe will be placed 2-3 cm lateral to the L3 spinous process, 15 ml of 0.25% bupivacaine will be injected into the interfacial space below the erector spinae muscle, above the transverse process. The same ESPB procedure was performed on the other side. In total, 30 ml of 0.25% bupivacaine was administered.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Intraoperative remifentanil consumption

    The amount of remifentanil that patients need to maintain anesthesia during the intraoperative period will be recorded.

    Measured: During the intraoperative period

Secondary outcomes (3)
  1. Mean arterial pressure

    Mean arterial pressure values will be recorded before anesthesia, before surgical incision, after surgical incision at the 5th, 30th, 60th, 90th, 120th minutes, and after general anesthesia.

    Measured: Perioperative period

  2. Heart rate

    Heart rate values will be recorded before anesthesia, before surgical incision, after surgical incision at the 5th, 30th, 60th, 90th, 120th minutes, and after general anesthesia.

    Measured: Perioperative period

  3. Pain scores

    Pain will be assessed at rest and while coughing using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain). Pain assessment will be done at the 1st, 2nd, 6th, 12th, and 24th hours after surgery.

    Measured: First 24 hours after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Preoperative Erector Spinae Plane Block and Postoperative Erector Spinae Plane Block in people with Lumbar Spine Surgery and Erector Spinae Plane Block, run by Atatürk Chest Diseases and Chest Surgery Training and Research Hospital at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Intraoperative remifentanil consumption (time frame: During the intraoperative period). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Nov 2025.
