肺癌切除术的死亡率为2.1～12.4%。死亡原因中肺部合并症最常见,也有人认为与手术后肺顺应性改变导致肺工作量增加有关。最近研究指出,上腹部手术可引起膈肌功能降低,但未见研究部胸手术对肺机制和呼吸肌功能的影响的报道。本文研究肺切除术后肺机制和呼吸肌功能的改变,以及这些改变与术后呼吸衰竭的关系。病人和方法 20例肺癌行肺切除术患者;男19例,女1例,平均年龄63(34～75)岁。术前肺功能
Mortality for lung cancer resection ranged from 2.1 to 12.4%. Pulmonary complications are the most common cause of death and others are thought to be associated with increased lung workload due to changes in lung compliance following surgery. Recent studies have pointed out that upper abdominal surgery can cause decreased diaphragmatic function, but no study of thoracic surgery on the lung mechanism and respiratory muscle function reported. This article studies the changes in lung mechanisms and respiratory muscle function after pneumonectomy, and the relationship between these changes and postoperative respiratory failure. Patients and Methods Twenty patients with lung cancer underwent pneumonectomy. There were 19 males and 1 females with an average age of 63 (34-75) years. Preoperative lung function
