Effect of Bilateral Transversus Thoracis Muscle Plane Block in Patients Undergoing Coronary Artery Bypass Graft Surgery.

"In the TTMP block group, an ultrasounded guided TTMP block was performed by an anesthesiologist, in ICU, before tracheal tube removal. Between the 4th et 5th rib, on each side, 40 ml of Ropivacaine 2 mg/ml, in association with Clonidine, was injected single-shot in the tranversus thoracis muscle plane. The targets of local anesthetic were the anterior branches of intercostal nerves from T2 to T6. Dexamethasone 8 mg was injected intravenously."
