Nerve Blocks for Postoperative Pain Management in Children Receiving a Subcutaneous Implantable Cardioverter-Defibrillator: A Case Series

Subcutaneous implantable cardioverter-defibrillator (S-ICD) placement causes significant postoperative pain. Limited research exists on nerve blocks for treating pediatric S-ICD pain. This case series presents pain outcomes in 10 children receiving nerve blocks for S-ICD placement. Nerve blocks performed include bilateral parasternal with left erector spinae plane (ESP), pectoralis with left ESP, fascial plane, and paravertebral blocks. The predominant combination of bilateral parasternal blocks with a left ESP block seemed to contribute toward adequate pain control. These children appeared to have low pain scores, low opioid consumption, and no block complications. Nerve blocks may benefit pediatric patients after S-ICD implantation.
