Abstract

BACKGROUND: Pectoral nerve blocks (PECS) can reduce intra-procedural anesthetic requirements and postoperative pain. Little is known on the utility of PECS in reducing pain and narcotic use after pacemaker (PM) or implantable cardioverter defibrillator (ICD) placement in children.OBJECTIVE: To determine whether PECS can decrease postoperative pain and opioid use after PM or ICD placement in children.METHODS: A single center, retrospective review of pediatric patients undergoing transvenous PM or ICD placement between 2015-2020 was performed. Patients with recent cardiothoracic surgery or neurologic/developmental deficits were excluded. Demographics, procedural variables, postoperative pain, and postoperative opioid usage were compared between patients who underwent PECS and those who underwent conventional local anesthetic (CONTROL).RESULTS: A total of 74 patients underwent PM or ICD placement with 20 patients (27%) undergoing PECS. There were no differences between PECS and CONTROL with regard to age, weight, gender, type of device placed, presence of congenital heart disease, type of anesthesia, procedural time or complication rates. Patients who underwent PECS had lower pain scores at 1, 2, 6, 18, and 24-hours compared to CONTROL. PECS patients had a lower mean cumulative pain score [PECS 1.5 (95%-CI 0.8-2.2) vs CONTROL 3.1 (95%-CI 2.7-3.5); P<0.001] and lower total opioid use [PECS 6.0 MME/m2 (95%-CI 3.4-8.6) vs CONTROL 15.0 MME/m2 (95%-CI 11.8-18.2); P=0.001] over the 24-hours post-implant.CONCLUSIONS: Pectoralis nerve blocks reduce postoperative pain scores and lower total opioid usage after ICD or PM placement. PECS should be considered at the time of transvenous device placement in children.
