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

Subcutaneous implantable cardioverter-defibrillator (S-ICD) placement may cause significant postoperative pain. Limited research exists on regional anesthesia for pediatric S-ICD placement. This case series examined transversus thoracic plane blocks (TTPBs), pectointercostal fascial plane blocks (PIFBs), pectoralis nerve I and II blocks, paravertebral, serratus anterior plane, and erector spinae plane blocks (ESPBs) in 10 children receiving S-ICDs. Parasternal nerve blocks consisting of TTPB or PIFB and left ESPB appeared to provide adequate pain control. These children had reduced opioid consumption, lower mean pain scores, longer delay in first postoperative analgesic, and no complications. Regional anesthesia may reduce pain after pediatric S-ICD implantation.
