Feasibility of subcutaneous implantable cardioverter-defibrillator implantation with opioid sparing truncal plane blocks and deep sedation.

Introduction: The subcutaneous implantable cardioverter-defibrillator (S-ICD) is most commonly implanted under general anesthesia (GA), due to the intraoperative discomfort associated with tunneling and dissection. Postoperative pain can be substantial and is often managed with opioids. There is a growing interest in transitioning away from the routine use of GA during S-ICD implantation, while also controlling perioperative discomfort without the use of narcotics.
