Classical versus modified erector spinae plane block for pain after single-level lumbar disc surgery

Comparison of the Effectiveness of Classical and Modified Erector Spinae Plane Blocks in Postoperative Analgesia Management Following Lumbar Spinal Surgery: A Prospective Study

Not applicable Interventional Samsun University · NCT07348523

What this trial studies

Adults aged 18–70 with ASA physical status I–III scheduled for single-level lumbar disc surgery under general anesthesia receive either a classical or a modified erector spinae plane block in addition to standard multimodal analgesia. Postoperative pain scores, opioid consumption, opioid-related side effects, and recovery markers such as time to mobilization and length of stay are compared between groups. Patients with bleeding disorders, allergy to local anesthetics, infection at the injection site, prior lumbar surgery, recent gabapentinoid or corticosteroid use, pregnancy, or inability to use a PCA device are excluded. The aim is to see if one block technique reduces pain and opioid needs to allow earlier mobilization and improved patient satisfaction.

Who should consider this trial

Good fit: Adults 18–70 years old, ASA I–III, scheduled for single-level lumbar disc surgery under general anesthesia who can use a PCA device and provide informed consent are the ideal candidates.

Not a fit: Patients on anticoagulants, with local infection or allergy to local anesthetics, previous lumbar spine surgery, recent gabapentinoid or corticosteroid use, pregnancy or breastfeeding, or inability/unwillingness to use PCA are unlikely to be eligible or to benefit.

Why it matters

Potential benefit: If successful, the preferred block technique could lower postoperative pain and opioid use after lumbar disc surgery, enabling earlier mobilization and shorter hospital stays.

How similar studies have performed: Other studies of erector spinae plane blocks and related regional techniques have shown reduced postoperative pain and opioid use after spine surgery, though data specifically on modified approaches remain limited.
