本研究旨在探讨术前肺功能常规检查异常与剖胸后心肺并发症的关系。资料取自18个月中剖胸的72例病人,均为男性,平均年龄56.6岁。使用水封式肺量计,用力深呼气3次,吸入雾化气管扩张剂后重复3次,然后从6次中最佳肺量图计算用力肺活量、1秒钟用力呼气量及二者的比值。由12秒钟通气量推算1分钟最大通气量。另用闭式氦稀释法检测用力肺活量,以标准肺量测定技术计算其他肺容量,并测定稳定状态弥散量。手术后病人分为两组:组1无并发症;组2有1种或多种并发症。
The purpose of this study was to investigate the relationship between routine preoperative pulmonary function tests and cardiopulmonary complications after thoracotomy. Data from 72 patients in the 18-month mid-sectioned chest, both men, with an average age of 56.6 years. Use water-sealed spirometer, forced deep breath 3 times, inhalation of aerosol tracheal dilator repeated 3 times, and then from 6 times the best spirometry calculation of forced vital capacity, forced expiratory volume of 1 second and both The ratio. The maximum ventilation for 1 minute is calculated from the ventilation for 12 seconds. Another closed helium dilution test for forced vital capacity, the standard spirometry to calculate other lung capacity, and to determine the steady state dispersion. Patients were divided into two groups after surgery: group 1 without complications; group 2 with 1 or more complications.
