Comparing parascapular sub‑iliocostalis plane block versus thoracic paravertebral block for multiple rib fractures

Continuous Block of Parascapular Sub-Iliocostalis Plane Versus Thoracic Paravertebral Plane for Analgesia in Patients With Traumatic Multiple Rib Fractures

Not applicable Interventional Zagazig University · NCT07493473

This tests whether a continuous parascapular sub‑iliocostalis plane block or a thoracic paravertebral block provides better pain relief and recovery for adults with unilateral multiple rib fractures.

What this trial studies

Adults with unilateral multiple rib fractures admitted to Zagazig University will be randomly selected and receive either a continuous parascapular sub‑iliocostalis plane block or a thoracic paravertebral block in addition to standard care. Baseline assessment includes vital signs, blood tests, chest X‑ray/CT to count rib fractures and calculate a Chest Trauma Score, and documentation of contraindications. Outcomes include pain scores, opioid requirements, hospital length of stay, ability to participate in physiotherapy, and block‑related complications such as pneumothorax or hemodynamic instability. Participants meet specific inclusion and exclusion criteria to ensure safety and comparability.

Who should consider this trial

Good fit: Adults aged 21–60 with unilateral multiple rib fractures (two or more), ASA I–III, BMI under 35, able to give informed consent and not already on mechanical ventilation are the intended participants.

Not a fit: Patients with hemodynamic instability, need for mechanical ventilation, significant head injury, coagulopathy, infection at the injection site, pregnancy, or other injuries preventing safe block placement are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the approach could improve pain control, reduce opioid use and hospital stay, and make chest physiotherapy easier for patients with rib fractures.

How similar studies have performed: Thoracic paravertebral blocks are well‑established for rib fracture pain and superficial chest wall blocks like erector spinae and serratus anterior blocks have shown promising results, while continuous parascapular sub‑iliocostalis plane block is less well studied.
