Bilateral transversus thoracis muscle plane block provides effective analgesia and enhances recovery after open cardiac surgery

Background The mid-sternum is the main source of pain after open cardiac surgery. aim this study was to investigate effect bilateral transversus thoracis muscle plane (TTMP) blocks on Methods Sixty patients were randomly divided into two groups: TTMP (TP group) or no nerve block (CO group). primary endpoint perioperative sufentanil consumption. secondary outcome measures included postoperative pain, flurbiprofen axetil administration, quality sleep extubation, time return gastrointestinal function, drain removal, Intensive Care Unit (ICU) stay time, and hospital stay. Results TP group reported significantly less consumption than CO group. had higher Numerical Rating Scale (NRS) scores at 1, 2, 6, 12, 24 h extubation both rest during movement groups. Compared with group，time first bowel movement, ICU decreased in rated as better nights extubation. Conclusion Bilateral can provide good analgesia for undergoing surgery promote recovery.
