Rhomboid intercostal block versus erector spinae plane block for pain after thoracotomy

Assessing the Effectiveness of Rhomboid Intercostal and Erector Spinae Plane Blocks After Lung Cancer Thoracotomy

NA · Cairo University · NCT07040618

This will test whether a rhomboid intercostal block or an erector spinae plane block gives better pain relief and reduces opioid use for adults with lung cancer having a thoracotomy.

What this trial studies

This is a randomized comparison of two ultrasound-guided chest wall nerve blocks—rhomboid intercostal block (RIB) and erector spinae plane block (ESPB)—performed before thoracotomy at the National Cancer Institute, Cairo University. Sixty patients will be randomly assigned to receive either RIB or ESPB 30–45 minutes before surgery, with general anesthesia standardized across groups. The primary outcome is 24-hour postoperative morphine consumption, and secondary outcomes include VAS pain scores, hemodynamic stability, time to first analgesic request, recovery duration, patient satisfaction, and nausea/vomiting. Data will be analyzed with appropriate statistical tests to identify which technique provides superior analgesia and opioid-sparing effect.

Who should consider this trial

Good fit: Adult female patients with lung cancer scheduled for thoracotomy (age 18–65 years), ASA II–III, BMI 20–35 kg/m², and able to give informed consent are the intended participants.

Not a fit: Patients with contraindications to regional anesthesia, severe organ failure, chronic pain or psychological disorders, or known allergy to local anesthetics or study opioids are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the preferred block could lower opioid use, improve pain control, and speed recovery after thoracotomy.

How similar studies have performed: Erector spinae plane block has shown promising pain relief in prior thoracic surgery reports, while rhomboid intercostal block is a newer technique with more limited published data.
