PECS Study for CIED Implantation Surgery

The current anaesthetic management of CIED surgery at Sickkids is local anaesthetic infiltration by the EP cardiologist or a Pectoral nerve block (PECS) on an ad-hoc basis depending on the anaesthesiologist on a case by case basis. It is not known whether one technique provides better post- operative pain control and fewer adverse events than the other. In either case, the patient receives opioids as required during and after the procedure. Patients typically go home with a prescription for opioids to be taken for the first few days after surgery. The PECS block is a recognized effective anaesthetic technique used for both intraoperative and postoperative pain control in adult breast surgery, chest wall procedures as well as one case report for CIED implantation and a small series in paediatric cardiac surgery. The advantages of the PECS block in these surgical procedures includes improved analgesia and reduced opioid use. The investigators plan to conduct an RCT with two groups. Group 1 will receive a PECS block (using 0.8 ml/kg of 0.25% bupivacaine with epinephrine 1: 200000 divided in two equal volumes between the two planes) by the anaesthesiologist and local infiltration (up to 0.2 ml/kg of 0.25% bupivacaine with epinephrine 1:200000) by the surgeon. Group 2 will receive local infiltration (up to 0.8 ml/kg 0.25 % bupivacaine with epinephrine 1:200000) by the surgeon alone. Both groups will be given opioids as rescue analgesics as deemed necessary during their procedure and as rescue analgesia postoperatively, so that no patient will have untreated pain.
