Postpneumonectomy综合症包括纵隔移位导致动态通过压缩的主要气道阻塞支气管和气管远端。少数病例报告描述的发展ARDS患者postpneumonectomy综合症。啤酒et al。(2017)描述的死亡率postpneumonectomy ARDS从33%到88%不等。一个可能遇到的困难插管和通风作为参数基于理想体重可能不适用。容易定位通风和医学界已经成功地在孤立的情况下使用。我们现在的这种情况下,强调管理的挑战。一个70岁的男性与远程的历史越战老兵右全肺切除术前三十年出现发烧、咳嗽和呼吸困难。物理考试是重要的T 36.3°C时,英国石油(BP) 162/73,心率145 BPM, RR 22次/分钟,ht。1.72、wt。78公斤,传播正确的左侧肺的声音和干罗音。实验室显示白细胞23.92 / nL和原降钙素0.84 ng / mL。 CXR showed left infiltrate and opacification of right hemithorax with right mediastinal shift. EKG showed atrial fibrillation. He was started on broad spectrum antibiotics for pneumonia, but deteriorated, and was intubated for respiratory distress from ARDS. Vasopressors were initiated for shock. Given the history of pneumonectomy, he was initially ventilated with lower tidal volumes (320 mL). However, incremental changes were made to tidal volumes, and ETT was repositioned several times for hypoxia. Epoprostenol and cisatracurium were also initiated. Positional changes would lead to sudden desaturation; hence, prone positioning ventilation was not done. He was not considered for ECMO due to his pneumonectomy status. Unfortunately, his condition worsened progressively and he expired. The guidelines for ARDS are well established. However, postpneumonectomy patients are unique as seen in our patient. It is unclear whether an endobronchial tube advanced into the left bronchus could have helped difficult airway management resulting from suspected postpneumonectomy syndrome as suggested by CXR. Higher tidal volumes were also unsuccessful in alleviating hypoxia and led to persistently elevated plateau pressures and driving pressures as high as 23, which was inconsistent with our goal of lung protective ventilation. Few case reports describe the successful use of prone positioning ventilation or ECMO in postpneumonectomy patients with ARDS. Although not well studied, low tidal volumes supported with ECMO may have been a favorable strategy for our patient.

postpneumonectomy状态是一个独特的实体相关的解剖和生理的挑战。其中一个挑战是postpneumonectomy综合症,患者中常见的肺切除术,其中包括动态气道阻塞造成压缩主支气管和远端气管的脊柱或主动脉由于旋转和纵隔转移。这些病人带来特别困难的挑战在通风由于增加呼吸道死腔和减少静脉返回容易分流和发展肺水肿(
