The perioperative management of patients with pulmonary hypertension requires an in-depth knowledge of the underlying disease, its related pathophysiology, effects of anaesthesia and surgery, as well as the appropriate pharmacotherapy. With respect to preoperative assessment, it is essential to review all available diagnostic findings, evaluate the patient's physical state, and to plan the anaesthetic procedure. Intraoperatively, the prevention of increases in pulmonary resistance and right ventricular decompensation appears essential. For this purpose, stress, hypothermia, decreased systemic perfusion, hypercapnia, hypoxemia, acidosis, and invasive mechanical ventilation should be avoided. If the pulmonary artery pressure exacerbates, application of inhaled nitric oxide or prostacyclins (iloprost), phosphodiesterase-III-inhibitors (milrinone) and phosphodiesterase-V-inhibitors (sildenafil), reflect first-line treatment options. In order to support the right ventricle, inotropes (adrenalin, dobutamine, levosimendan) or inodilators (milrinone) increase its contractility. Dependent on severity of disease and the magnitude of surgical intervention, patients with pulmonary hypertension require a specific continuous monitoring as well as trained staff in the postoperative period.
肺动脉高压患者的围手术期管理需要深入了解基础疾病、其相关病理生理学、麻醉和手术的影响以及适当的药物治疗。关于术前评估,回顾所有可用的诊断结果、评估患者的身体状况并规划麻醉程序至关重要。术中,预防肺阻力增加和右心室失代偿似乎至关重要。为此,应避免应激、体温过低、全身灌注减少、高碳酸血症、低氧血症、酸中毒和有创机械通气。如果肺动脉压加剧,吸入一氧化氮或前列环素(伊洛前列素)、磷酸二酯酶-III抑制剂(米力农)和磷酸二酯酶-V抑制剂(西地那非)的应用是一线治疗选择。为了支持右心室,正性肌力药物(肾上腺素、多巴酚丁胺、左西孟旦)或血管扩张剂(米力农)可增加其收缩力。根据疾病的严重程度和手术干预的程度,肺动脉高压患者在术后需要进行特定的持续监测以及训练有素的工作人员。
