术前呼吸功能锻炼对胸心外科手术患者肺功能的影响

Effects of Preoperative Respiratory Exercise on Lung Function in Patients Undergoing Thoracic and Cardiac Surgery

目的观察术前呼吸功能锻炼对胸心外科手术患者肺功能的影响。方法选取在本院进行胸外手术的80例患者作为研究对象。随机分为对照组(采用常规治疗)和实验组(在术前给予呼吸功能锻炼指导),各40例。观察两组患者各项肺功能指标的差异。结果经过呼吸功能锻炼指导后,实验组最大通气量、时间通气量、血氧饱和度、时间肺活量等肺功能指标均显著优于对照组(P <0.05)。实验组并发症发生率显著低于对照组(P <0.05)。结论对胸心外科手术患者实施术前呼吸功能锻炼,可以改善肺功能,提高手术耐受力。

Objective To observe the effects of preoperative respiratory exercise on lung function of patients undergoing thoracic and cardiac surgery. Methods A total of 80 patients admitted to our hospital for thoracic surgery were selected as subjects. The patients were randomly divided into control group(conventional treatment)and experimental group(preoperative instruction on respiratory function exercise),with 40 cases each. To observe the difference of pulmonary function indexes between the two groups. Results After respiratory function exercise,the most significant indexes of lung function in the experimental group were superior to the control group(P <0.05). The complication rate of the experimental group was significantly lower than that of the control group(P <0.05). Conclusion Preoperative breathing exercises for patients undergoing thoracic and cardiac surgery can improve lung function and surgical tolerance.
