Hybrid Airway Management for Neuromonitoring-guided Selective Phrenic Nerve Surgery in Intractable Hiccups: A Case Report

92 mmHg. Sugammadex was administered intraoperatively to restore diaphragmatic motor responses required for branch-specific neuromonitoring. The medial and anterolateral branches of the right phrenic nerve exhibited abnormal electrophysiological responses and were treated with selective bipolar ablation and clipping. Postoperatively, the patient remained on room air, reported no intraoperative recall, and showed no clinically relevant diaphragmatic dysfunction on clinical and functional assessment. This case illustrates that established anaesthetic techniques can be carefully adapted to meet the competing requirements of lung isolation, anaesthetic depth control, and neuromonitoring in selected patients undergoing phrenic nerve surgery for intractable hiccups.
