Intertransverse process block to improve recovery and cut long-term pain after open-heart surgery

Official title: Intertransverse Process Block to Improve Quality of Recovery and Pain Management in Adult Cardiac Surgical Patients: a Prospective Double-Blinded Randomized Controlled Trial

Run by Chinese University of Hong Kong · NCT06946290 · Data updated 2026-11-12

We will test whether giving an intertransverse process block during elective open-heart (CABG or valve) surgery helps adults recover better after surgery and reduces the chance of long-term post-surgery pain.

Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older scheduled for elective CABG, valve repair/replacement, or combined CABG/valve surgery via sternotomy who do not have preexisting chronic pain or chronic opioid use are the intended participants.

Probably not a fit

Patients having emergency or redo operations, those with preexisting chronic pain or chronic opioid/sedative use, severe renal failure (eGFR ≤30 ml/min), or who require intraoperative remifentanil are unlikely to benefit from this protocol.

What this trial studies

This randomized interventional trial assigns adults having elective coronary artery bypass grafting or valve repair/replacement via sternotomy to receive either an intertransverse process block (ITPB) or a sham block. Researchers will track immediate postoperative pain control and quality of recovery, and then follow patients for persistent pain at 3, 6, and 12 months. Patients with prior chronic pain, chronic opioid use, emergency or redo surgery, severe renal failure, or intraoperative remifentanil are excluded. The main goal is to determine whether blocking nociceptive input around the transverse processes reduces acute pain and prevents central sensitization that can lead to chronic postsurgical pain.

Why it matters

Potential benefit: If successful, the block could lower immediate postoperative pain, speed recovery, and reduce the incidence of chronic postsurgical pain after cardiac surgery.

How similar studies have gone: Related regional techniques such as erector spinae and paravertebral blocks have shown promise for reducing postoperative pain after thoracic procedures, but ITPB specifically remains less well studied for preventing chronic postsurgical pain.
