术前呼吸功能锻炼对胸心外科手术患者的应用效果分析

Analysis on Application Effect of Preoperative Respiratory Function Exercise in Patients Undergoing Cardiothoracic Surgery

目的:探讨术前呼吸功能锻炼对胸心外科手术患者的应用效果。方法:选取2017年3月-2018年3月湖北省襄阳市老河口第一医院收治的70例胸心外科手术患者作为研究对象,随机分为两组,各35例。对照组实施术前常规训练,观察组实施术前呼吸功能锻炼,比较两组患者肺功能指标、血气分析指标及并发症发生率。结果:干预前,两组各肺功能指标比较,差异无统计学意义(P>0.05);干预后,观察组呼吸频率低于对照组,用力肺活量、1 s呼气量及最大深吸气量均高于对照组,差异有统计学意义(P<0.05);干预后,观察组的动脉血氧分压、动脉血氧饱和度均高于对照组,差异有统计学意义(P<0.05);观察组术后并发症发生率低于对照组,差异有统计学意义(P<0.05)。结论:术前呼吸功能锻炼对胸心外科手术患者的应用效果显著,改善了患者的肺部功能及血气分析指标,降低了术后并发症发生率,值得推广应用。

Objective:To investigate the application effect of preoperative respiratory function exercise in patients undergoing cardiothoracic surgery.Methods:A total of 70 patients with cardiothoracic surgery admitted to the First Hospital of Laohekou in Xiangyang City from March 2017 to March 2018 were selected as the study subjects and randomly divided into two groups,with 35 patients in each group.The control group received routine exercise and the observation group received preoperative respiratory function exercise.The pulmonary function index,blood gas analysis index and incidence of complication in two groups were compared.Results:Before the intervention,there was no significant difference in the pulmonary function indexes between the two groups(P>0.05);after the intervention,the respiratory rate of the observation group was lower than that of the control group,and the forced vital capacity,forced expiratory volume within 1 second and maximum deep inspiratory capacity were all higher than those of the control group,the difference was statistically significant(P<0.05).After intervention,the arterial blood oxygen partial pressure and arterial blood oxygen saturation in the observation group were higher than those in the control group,and the difference was statistically significant(P<0.05).The incidence of postoperative complications in the observation group was lower than that in the control group,and the difference was statistically significant(P<0.05).Conclusion:Preoperative respiratory function exercise has a significant application effect on patients undergoing cardiothoracic surgery,improves the patients'pulmonary function and blood gas analysis indicators,and reduces the incidence of postoperative complications,which is worthy of popularization and application.
