摘　　要：目的探讨冠脉搭桥术后低氧血症患者早期呼吸训练器治疗的疗效。方法选取2013年1月2018年5月我院行冠脉搭桥术患者48例作为研究对象,按照治疗方式的不同分为对照组(22例)与观察组(26例),对照组采取常规治疗,观察组在对照组基础中联合呼吸训练器展开呼吸功能锻炼。观察两组术前、拔管3d后1秒用力呼气容积(forced expiratory volume in one second,PEV_1)、PEV_1/FVC用力呼气量占用力肺活量(forced vital capacity,FVC)的比重,记录两组术前、拔管3d后PaO_2、PaCO_2、机械通气时间与总住院时间。结果两组术前PEV_1、PEV_1/FVC均无统计学差异(P> 0. 05);拔管后3d,观察组PEV_1/FVC显著高于对照组(P <0. 05);两组机械通气时间和ICU住院时间无统计学差异(P> 0. 05)。观察组总住院时间短于对照组(P <0. 05);两组术前PaO_2、PaCO_2均无统计学差异(P> 0. 05),拔管后3d,观察组PaO_2显著高于对照组(P <0. 05),两组PaCO_2各时间点均无统计学差异(P> 0. 05)。结论行冠脉搭桥术后患者早期给予呼吸训练器治疗,可提高机体肺部功能,促进氧合,使患者尽早恢复健康。Objective To investigate the effect of early respiratory exerciser training in the treatment of patients with hypoxemia after coronary artery bypass grafting.Methods 48patients underwent coronary artery bypass grafting in our hos- pital from January 2013to May 2018were selected and divided into two groups according to the different treatment meth- ods.Control group (n =22)received the routine treatment,based on this,the observation group (n =26)received early respiratory exerciser training.Then various indicators were observed and recorded before operation and 3d after the extubation, including forced expiratory volume in one second (PEV1),PEV1/forced vital capacity (PEVJFVC),PaO2,PaCO2,me- chanical ventilation time and total length of stay.Results The PEV1 and had PEV1/FVC had no difference before operation (P >0.05).At the post-extubation 3d,the PEV1/FVC of the observation group was higher than that of the control group (P <0.05).The duration of mechanical ventilation and the ICU stay of two groups had no difference (P >0.05), however,the total length of stay of the observation group was shorter than that of the control group (P <0.05).The PaO2 and PaCO2had no difference before operation (P >0.05).At the post-extubation 3d,the PaO2of the observation group was higher than that of the control group (P <0.05),while no difference was found in PaCO2between groups at each time point (P >0.05).Conclusion The application of early respiratory exerciser training can effectively ameliorate the pulmonary function,promote the oxygenation and recovery for patients with hypoxemia after coronary artery bypass grafting.
