Brief summary

Coronary artery bypass graft surgery is the standard surgical treatment for coronary disease. However, there is no consensus on analgesic management in patients undergoing CABG. The aim of the study is to evualuate efficacy of bilateral transversus thoracis muscle plane (TTMP) block combined with systemic analgesia, compared to systemic analgesia only, in patients undergoing elective on-pump CABG surgery. Our main hypothesis is that a bilateral TTMP block performed after CABG surgery could reduce morphine consumption during the first 48 hours. The investigators conducted an age, gender and type of surgery-matched retrospective cohort study in the Montpellier University Hospital (France).

Interventions

PROCEDUREUltrasound guided Bilateral Transversus Thoracis Muscle Plane block

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.
