Why the study?
Managing pain after median sternotomy is challenging, and evidence of sustained postoperative benefit from regional anesthesia in cardiac surgery remains limited and heterogeneous.
Does surgeon-administered regional anesthesia reduce total opioid consumption in patients undergoing non-emergent coronary artery bypass grafting?
Does surgeon-administered regional anesthesia reduce total opioid consumption in patients undergoing non-emergent coronary artery bypass grafting?
Surgeon-administered regional anesthesia with bupivacaine, epinephrine, clonidine, and dexamethasone does not reduce opioid consumption or provide additional clinical benefits following median sternotomy for CABG.
No opioid-sparing benefit from surgeon-administered infiltration after CABG; challenges routine adoption pending confirmatory trials.
