术前呼吸训练改善肺减容术后患者呼吸功能效果观察

目的探讨术前呼吸训练对晚期慢性阻塞性肺疾病患者行肺减容术后呼吸功能的影响。方法将27例单、双侧肺减容术患者随机分为对照组(15例)和训练组(12例)。对照组术前不进行呼吸训练,训练组行深慢腹式呼吸、缩唇呼吸、咳嗽训练等呼吸训练。比较两组患者术后脱机时间和手术前后血气分析和肺功能等指标。结果训练组患者术后脱机时间明显短于对照组(P<0.05);两组患者手术前后血气分析和肺功能各项指标明显改善(均P<0.01);训练组术后3个月与6个月血气分析和肺功能各项指标明显优于对照组(均P<0.05)。结论术前常规呼吸训练利于肺减容术后患者呼吸功能早日恢复。

Clinical Observation on the Effect of Respiration Exercise on Respiratory Function After Lung Volume Reduction Surgery

Objective To explore the effect of respiration exercise on respiratory function after lung volume reduction surgery. Methods Twenty-seven cases of unilateral or bilateral lung volume reduction surgery were divided into an exercise group (n=12) and a control group (n=15). The control groups were using traditional method before the operation, while the patients in the exercise group were asked to perform respiration exercise before the surgery, including deep and slow abdominal respiration, half-closed lip respiration and coughing,etc. The control groups were using traditional method the patients were compared in terms of the interval from the time when the patients were on breathin apparatus and the time when they were off the machine after the operation, pre- and postoperative results of blood gas analysis and lung functions.Results The interval of the exercise group was significantly shorter than that of the control group (P<0.05). Blood gas results and lung functions were greatly improved after surgery in the exercise group (P<0.01 for all). There were significant differences in the results of blood gas analysis and lung functions between the exercise group and the controls 3 and 6 months after the operation (P<0.05 for all). Conclusion The regular respiration exercise before surgery can improve the respiratory function after lung volume reduction surgery.
