术前呼吸功能锻炼对瓣膜置换患者肺功能影响

Effect of Preoperative Respiratory Function Exercises on Pulmonary Function of Patients under Valvular Heart Disease Replacement

目的评估术前呼吸功能锻炼对改善肺功能的效果.方法随机选取2001年6月～2004年9月瓣膜置换术者48例,术前1～3周进行呼吸功能锻炼,观察锻炼前后患者肺功能改善情况.结果锻炼后患者的呼吸频率显著减慢,用力呼吸(FVC)、第1秒用力呼吸量(FEV1)、血氧饱和度(SaO2)、指脉氧饱和度(SpO2)较锻炼前均有不同程度提高(P＜0.01).结论呼吸功能锻炼可改善患者的肺功能,提高患者对手术的耐受性.

Objective To evaluate the effects of improvement of pulmonary function of pa- tients treated by preoperative respiratory function exercises. Methods From June 2001 to September 2004,48 valvular heart disease replacement patients were choosed randomly. The effects of improvement of pulmonary function result from respiratory function exercises 1 ～3 weeks before operation were observed and analyzed. Results After training,the patietnt＇s respiration frequency decreased notably, FVC ,FEV1 ,SaO2 ,and SpO2 all was improved to a certain extent after respiratory function exercises（ P 〈0. 01 ）. Conclusion Pulmonary function in valvular heart disease replacement patients was im- proved, operative＇endurance enhanced,and postoperative complication in respiratory organs decreased to an extent through respiratory function exercises.
