Efficacy and safety of supraclavicular and pectoralis nerve blocks as primary peri‐procedural analgesia for cardiac electronic device implantation: A pilot study

Background Cardiac implantable electronic devices (CIEDs) are routinely implanted using intravenous drugs for sedation. However, some patients are poor candidates for intravenous sedation. Objective We present a case series demonstrating the safety and efficacy of a novel, ultrasound‐guided nerve block technique that allows for pre‐pectoral CIED implantation. The targets are the supraclavicular nerve (SCN) and pectoral nerve (PECS1). Methods We enrolled 20 patients who were planned for new CIED implantation. Following US‐localization of the SCN and PECS1, local anesthetic (LA) was instilled at least 30–60 min pre‐procedure. Successful nerve block was determined if
