M-TAPA Block for Analgesia After Open-Heart Surgery
80 participantsStarted 2026-01-15
Plain-language summary
Postoperative pain following open-heart surgery is primarily caused by median sternotomy, although additional contributors include costovertebral joint stress related to sternal retraction and the presence of chest wall and mediastinal drains during the postoperative period. This pain is often severe, especially in the early postoperative hours, making effective management both challenging and essential. Insufficient pain control frequently necessitates high doses of opioids, which may lead to adverse effects such as nausea, vomiting, respiratory complications, and postoperative delirium. Excessive use of anesthetic agents or opioids can also delay extubation and prolong the process of weaning from mechanical ventilation.
The modified thoracoabdominal nerve block through the perichondrial approach (M-TAPA) is a regional anesthesia technique performed beneath the costal margin between the internal oblique and transversus abdominis muscles. It provides broad dermatomal coverage, extending approximately from the upper thoracic to the lower thoracic and upper lumbar segments. This study aims to evaluate the postoperative analgesic effectiveness of combining the M-TAPA block with a parasternal block in patients undergoing open-heart surgery.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
