Abstract

Abstract: Funding Acknowledgements: NONE Background: operative anesthetic requirements and peri-operative discomfort are barriers to wide adoption of the subcutaneous implantable cardioverter defibrillator (S-ICD) system expecially when the intermuscular technique is used due to the greater amount of tissue dissection. The procedure is most commonly performed under general anesthesia (GA). There is growing interest in transitioning away from the routine use of GA and towards several alternative anesthesia modalities implifying the anesthetic management of the S-ICD implant procedure without the involvement of an anesthesiologist. Purpose: we assessed the feasibility of ultrasound-guided serratus anterior plane block (US-SAPB) in patients undergoing S‐ICD implantation with the intermuscular two-incision technique. Methods: the study population included 38 consecutive patients (84% male; median, 53 [46‐62] years) who received S‐ICD implantation using the intermuscular two-incision technique. All procedures were performed under US-SAPB and sedoanalagesia without the involvement of an anesthesiologist. Results: the average procedure time was 67 ± 14 minutes.No patient experienced significant hemodynamic changes or oxygen desaturation during the period of US- SAPB procedure and sedation; there was no need for pharmacological interventions. The whole procedute was well tollerated without discomfort and complications in the absence of needing GA except in one (2.6%) patient who required GA with laryngeal mask airway. Patients remained always able to respond appropriately to neurological monitoring during S-ICD implantation procedure. There were no procedure-related complications. Conclusion: US-SAPB and the intermuscular two-incision technique may be a safe and feasible promising combination for S-ICD implantation overcoming potential barrier to wieder S-ICD adoption in the clinical practice.
