Indirect inhibition of an external temporary pacemaker by electrocautery is reported. Before induction of general anesthesia for a hemimaxillectomy and radical neck dissection, a temporary transvenous demand pacemaker was inserted into a patient with a first-degree atrioventricular block and complete left bundle-branch block. Although we provided common precautions to prevent electromagnetic interference by electrocautery, pacing failure still occurred. It was thought to be caused by current dispersing from the active electrocautery electrode. This case suggests that occipital placement of the electrocautery ground plate should be considered during neck surgery in a patient requiring a temporary pacemaker.
据报道，电灼可间接抑制体外临时起搏器。在为一名患者进行半侧上颌骨切除术和根治性颈清扫术并诱导全身麻醉之前，将一个临时经静脉按需起搏器插入一名患有一度房室传导阻滞和完全性左束支传导阻滞的患者体内。尽管我们采取了常规预防措施以防止电灼产生的电磁干扰，但仍发生了起搏失败。据认为这是由来自有源电灼电极的电流扩散所致。该病例表明，在为需要临时起搏器的患者进行颈部手术时，应考虑将电灼接地极板放置在枕部。
