Comparing two chest-wall nerve blocks (TTPB vs PIFB) to reduce pain after open-heart bypass surgery

Transversus Thoracic Muscle Plane Block Versus Pectointercostal Fascial Block for Enhanced Recovery After Cardiac Surgery: A Randomized Controlled Trial

Not applicable Interventional Assiut University · NCT07417462

This will test whether two ultrasound-guided chest-wall nerve blocks (transversus thoracic muscle plane block or pectointercostal fascial block) reduce pain and speed recovery for adults aged 40–60 having open-heart bypass surgery.

What this trial studies

Post-sternotomy pain is often severe in the first 24 hours and can slow recovery after open cardiac procedures. This study compares two ultrasound-guided regional anesthesia techniques, the transversus thoracic muscle plane block (TTPB) and the pectointercostal fascial block (PIFB), against a sham control in patients undergoing coronary artery bypass grafting with median sternotomy. Both blocks target the anterior cutaneous branches of the intercostal nerves (T2–T6) to provide analgesia to the parasternal and medial anterior chest wall, and the study will record pain scores, opioid consumption, and recovery measures after surgery. Eligible patients receive perioperative ultrasound-guided blocks and are followed through the immediate postoperative period to compare analgesic efficacy and enhanced recovery outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults 40–60 years old with BMI under 35, ASA physical status II–III, left ventricular ejection fraction ≥30%, scheduled for elective coronary artery bypass grafting via median sternotomy.

Not a fit: Patients undergoing valve replacement, emergency or redo operations, minimally invasive approaches, those with severe organ dysfunction, LVEF below 30%, known allergy to local anesthetics, cognitive impairment, or who are pregnant or breastfeeding are unlikely to be eligible or to receive benefit from these blocks.

Why it matters

Potential benefit: If successful, these nerve blocks could reduce sternotomy pain, lower opioid use, and help patients recover faster after bypass surgery.

How similar studies have performed: These blocks are relatively new but early case series and small randomized studies have suggested they can reduce postoperative chest pain and opioid use, though larger definitive trials are limited.
