关于肺动脉高压（PH）患者麻醉方法的选择尚未达成共识。我们报道了两例在严重 PH 患者开腹手术时无需全身麻醉而安全进行椎管内麻醉的病例。 病例 1：一名 59 岁女性，患有房间隔缺损和腹部巨大肿瘤，平均肺动脉压(PAP) 为 39 mmHg，肺血管阻力 (PVR) 为 3.5 Wood 单位。病例 2：一名 23 岁女性，患有遗传性肺动脉高压（平均 PAP，65 mmHg；PVR，16.45 Wood 单位）。两名患者均在椎管内麻醉下接受开腹手术，术中使用血管收缩剂，没有发生循环衰竭。虽然麻醉护理必须根据 PH 的病理学和严重程度进行个性化，但椎管内麻醉可能是接受腹部手术的严重 PH 患者的一种选择。© 2024 . 作者。

There is no consensus regarding the choice of anesthetic method for patients with pulmonary hypertension (PH). We report two cases in which neuraxial anesthesia was safely performed without general anesthesia during open abdominal surgery in patients with severe PH.Case 1: A 59-year-old woman had an atrial septal defect and a huge abdominal tumor with a mean pulmonary arterial pressure (PAP) of 39 mmHg and pulmonary vascular resistance (PVR) of 3.5 Wood units. Case 2: A 23-year-old woman who had hereditary pulmonary artery hypertension (mean PAP, 65 mmHg; PVR, 16.45 Wood units). Both patients underwent open abdominal surgery under neuraxial anesthesia without circulatory collapse with intraoperative administration of vasoconstrictors.Although anesthetic care must be personalized depending on the pathology and severity of PH, neuraxial anesthesia may be an option for patients with severe PH undergoing abdominal surgery.© 2024.
