目的探讨食管癌病人手术后呼吸功能变化的规律。方法 2002年1月至2006年1月,选取200例食管癌病人,行食管癌切除食管胃弓上吻合术100例,弓下吻合术100例。在手术前3 d 和手术后1、2、3、5、7、10、14 d 进行肺功能和血气分析测定,动态观察呼吸功能的变化规律。结果肺功能各项指标于术后第2 d 降至最低,以后呈逐渐升高趋势,至术后14 d 恢复到术前的60%;动脉氧分压恢复到术前的90%。肺功能各项指标、动脉氧分压弓上吻合术较弓下吻合术低。结论食管癌术后呼吸功能明显减退,造成低氧血症,应积极纠正。
Objective To investigate the changes of respiratory function after esophageal cancer surgery. Methods From January 2002 to January 2006, 200 cases of esophageal cancer patients underwent esophagectomy and esophagogastric anastomosis in 100 cases under esophageal anastomosis. Lung function and blood gas analysis were performed 3 days before surgery and 1, 2, 3, 5, 7, 10 and 14 days after surgery. The changes of respiratory function were observed dynamically. Results The indexes of pulmonary function decreased to the lowest on the 2nd postoperative day, and then increased gradually to 60% postoperatively on the 14th postoperative day. The arterial partial pressure of oxygen returned to 90% preoperatively. Pulmonary function indicators, arterial oxygen pressure bow anastomosis than bow anastomosis is low. Conclusion Postoperative esophageal respiratory function was significantly decreased, resulting in hypoxemia, should be actively corrected.
