Trial summary

Retrolaminar block (RLB) and erector spinae plane block (ESPB) are alternative approaches to paravertebral block (PVB) and are advantageous in that they are easier and safer techniques compared with the traditional PVB. These blocks are considered to be compartment blocks or interfascial plane blocks. Read more about this study

About this study

Official title: Comparison Between the Efficacy of Ultrasound Guided Erector Spinae Plane Block Versus Retrolaminar Plane Block for Postoperative Pain in Patients Undergoing Hepatobiliary Surgery

Retrolaminar block (RLB) and erector spinae plane block (ESPB) are alternative approaches to paravertebral block (PVB) and are advantageous in that they are easier and safer techniques compared with the traditional PVB. These blocks are considered to be compartment blocks or interfascial plane blocks. In these approaches, local anesthetics are assumed to penetrate the superior costotransverse ligament and reach the paravertebral space, although the needle tip is not advanced into the paravertebral space.

the study aim to evaluate and compare the analgesic efficacy of retrolaminar plane block and erector spinae plane block.

What participants receive

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

  • retrolaminar blockProcedure or surgery

    curved probe will be placed 1-1.5 cm lateral to the target spinous process after identification of the lamina, the needle will be advanced caudally until it contacts the lamina

  • ESPBProcedure or surgery

    curved probe will be placed 2-3 cm lateral to the spine using a sagittal approach at the level of T8. After identification of erector spinae muscle and transverse processes, the needle will be inserted deeply into the erector spinae muscle.

What is being measured

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

  1. Visual analogue pain scale

    score from 0-10 (0 mean no pain and 10 the worst pain )

    Measured: 24 hour

Secondary outcomes (2)
  1. Time of first post operative analgesic request.

    time to demand rescue analgesia

    Measured: 24 hour

  2. Total analgesic consumption

    total fentanyl consumption during the first day postoperative

    Measured: 24 hour

Questions about this trial

What is this clinical trial studying?

A study testing retrolaminar block and ESPB in people with Post Operative Pain and Analgesia, run by Minia University at 1 site in Egypt.

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 4 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 13 Oct 2023. 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 Egypt. 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?

Visual analogue pain scale (time frame: 24 hour). 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 13 Oct 2023; AzTrials last refreshed its copy on 7 Nov 2026.
