About this study
Official title: Comparison of Analgesic Efficacy of Erector Spinae Plane Block and External Oblique-Intercostal Plane Block in Patients Undergoing Open Ventral Hernia Repair
The aim of this study is to compare the postoperative analgesic efficacy of bilateral erector spinae plane block and bilateral external oblique-intercostal plane block in patients undergoing open ventral hernia repair.
Read the detailed description
The effectiveness of trunk blocks applied at equivalent doses will be evaluated in order to most effectively treat postoperative pain, minimize nausea and vomiting, and optimize the comfort of patients during the postoperative period after open ventral hernia repair operations. The methods used in this study are proven safe in ventral hernia repair surgery and other abdominal surgeries, and are routinely performed in our clinic. The procedures performed pose no additional risks to patients compared to routine procedures.
- Being tested
- Erector Spine Plane Block, External Oblique - Intercostal Plane Block
- Keywords
- erector spinae plane block, external oblique intercostal plane block, bupivacain
- Medical subject headings

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Erector Spine Plane BlockProcedure or surgery
Bilateral erector spinae plane block was performed under aseptic conditions at the T7 vertebral level using ultrasound guidance with a convex probe. An 80-mm peripheral nerve block needle was inserted 3-4 cm lateral to the midline with an in-plane approach to the fascial plane deep to the erector spinae muscle. After negative aspiration and hydrodissection with 1-3 ml of saline, 30 ml of 0.25% bupivacaine was injected on each side, with craniocaudal spread confirmed by ultrasound. Patients were then positioned for surgery.
External Oblique - Intercostal Plane BlockProcedure or surgery
Bilateral external oblique-intercostal plane block was performed under aseptic conditions by identifying the 6th and 7th ribs along the midclavicular line. Using ultrasound guidance with the probe placed parallel to the midclavicular line, the ribs, intercostal muscles, external oblique muscle, and pleura were visualized. A 50-mm block needle was advanced craniocaudally into the plane between the external oblique and intercostal muscles. After negative aspiration and hydrodissection with 1-3 ml saline, 30 ml of 0.25% bupivacaine was injected on each side, with craniocaudal spread confirmed by ultrasound. Patients were then positioned for surgery.

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. Some participants in this study may receive a placebo. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Ali KOC, MD (90 312 567 70 00 ext. 1332, alikoc.md@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Tramadol Consumption (time frame: 24 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07163026, which also lists 5 linked publications.
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 16 Sep 2025; AzTrials last refreshed its copy on 6 Nov 2026.
