Asystole during posterior fossa neurosurgical procedures is not uncommon. Various causes have been implicated, especially when surgical manipulation is carried out in the vicinity of the brain stem. The trigemino-cardiac reflex has been attributed as one of the causes. Here, we report two cases who suffered asystole during the resection of posterior fossa tumors. The vago-glossopharyngeal reflex and the direct stimulation of the brainstem were hypothesized as the causes of asytole. These episodes resolved spontaneously following withdrawal of the surgical stimulus emphasizing the importance of anticipation and vigilance during critical moments of tumor dissection during posterior fossa surgery.
后颅窝神经外科手术期间出现心搏停止并不罕见。已发现多种原因，尤其是在脑干附近进行手术操作时。三叉神经 - 心脏反射被认为是原因之一。在此，我们报告两例在后颅窝肿瘤切除术中发生心搏停止的病例。推测迷走 - 舌咽反射和脑干直接刺激是心搏停止的原因。在手术刺激撤除后，这些发作自行缓解，强调了在后颅窝手术肿瘤切除关键阶段进行预判和保持警惕的重要性。
