Palliative esophageal bypass surgery for patients with esophageal cancer and esophagobronchial fistula aims restoring the ability of swallowing as well as preventing pulmonary aspiration. Perioperatively, there are several problems in respiratory management for such patients. Repeated episodes of pulmonary aspiration exaggerate bronchopneumonia. Positive pressure ventilation may cause air leakage via fistula resulting in inadequate ventilation, distension of the stomach and regurgitation of gastric contents; thus, maintaining of spontaneous ventilation is a crucial concern. Here we report an anesthetic management of a 51-year-old woman with esophageal cancer and esophagobronchial fistula undergoing esophageal bypass surgery. We could not apply neuraxial block due to hypocoagulability. We performed awake tracheal intubation, and general anesthesia was maintained using sevoflurane supplemented by morphine, fentanyl and ketamine under spontaneous ventilation until the resection of gastroesophageal junction and the installation of a drainage catheter into the esophagus. Muscle relaxation required for surgery was sufficiently obtained by sevoflurane anesthesia without administration of muscle relaxants. After the installation of the drainage catheter, the lungs were ventilated mechanically until the end of surgery. The surgery was uneventful. The patient emerged from general anesthesia smoothly, and was extubated. The postoperative course of this patient was also uneventful.
对于患有食管癌和食管支气管瘘的患者,姑息性食管旁路手术旨在恢复吞咽能力并防止肺误吸。围手术期,这类患者的呼吸管理存在几个问题。反复发生的肺误吸会加重支气管肺炎。正压通气可能会通过瘘口导致漏气,从而造成通气不足、胃扩张和胃内容物反流;因此,维持自主通气是一个关键问题。在此,我们报告一例51岁患有食管癌和食管支气管瘘的女性患者接受食管旁路手术的麻醉管理情况。由于凝血功能低下,我们无法实施神经轴阻滞。我们进行了清醒气管插管,并在自主通气下使用七氟醚维持全身麻醉,同时补充吗啡、芬太尼和氯胺酮,直至胃食管交界处切除并在食管内放置引流导管。通过七氟醚麻醉充分获得了手术所需的肌肉松弛,无需使用肌肉松弛剂。放置引流导管后,机械通气直至手术结束。手术过程顺利。患者顺利从全身麻醉中苏醒并拔管。该患者的术后过程也很顺利。
