振动排痰仪对肺部感染合并呼吸衰竭患者的疗效观察

摘要 目的：探讨振动排痰仪在肺部感染合并呼吸衰竭治疗中的应用价值。 方法：将2008年7月-2010年7月我科收治的58例肺部感染合并呼吸衰竭患者随机分成两组：A组（治疗组）29例，B组（对照组）29例。A组采用振动排痰仪行排痰治疗；B组应用人工叩背法行排痰治疗。观察并比较两组治疗前后SpO2、 PaO2,、PaCO2、肺部湿罗音、痰量、ICU住院时间。 结果：A组排痰效果及肺部湿罗音改善均优于B组。A组和B组治疗后第7天的SpO2分别为（94.48±3.18）%、（92.21±2.88）%；PaO2分别为（70.38±6.90）mmHg、（66.31±7.49）mmHg；PaCO2分别为（40.34±3.63）mmHg、（43.41±3.27）mmHg；ICU住院时间分别为（9.31±2.59）天，（11.66±3.53）天，两组比较差异均有统计学意义（P<0.05）。结论：振动排痰仪对肺部感染合并呼吸衰竭患者协助排痰效果显著，有利于感染控制，改善患者肺功能，缩短住院天数，值得临床推广。

Observation of clinical value of percussive mobilizer sputum elimination apparatus in patients pulmonary infection and respiratory failure

Abstracts Objective：To investigate the clinical value of percussive mobilizer sputum elimination apparatus in pulmonary infection combined with respiratory failure. Methods：From July 2008 to July 2010, 58 patients with pulmonary infection combined with respiratory failure were randomly divided into two groups: 29 patients in group A (treatment goup) and 29 patients in group B (control group). A group were treated with G5 Percussive Mobilizer made in America, B group were treated with knock expectoration.The SpO2, PaO2, PaCO2, moist rales of lung, expectoration, the daily sputum volume and ICU stay were observed and compared. Results：Compared group B, the efficiency of sputum elimination and improvement of moist rales were better in group A.There were significant differences between group A and group B in SpO2 ((94.48±3.18) % versus (92.21±2.88) %), PaO2 ((70.38±6.90) mmHg versus (66.31±7.49) mmHg), PaCO2 ((40.34±3.63) mmHg versus (43.41±3.27) mmHg) ICU stay ((9.31±2.59)d versus (11.66±3.53)d) (P<0.05). Conclusion：Percussive mobilizer sputum elimination apparatus had signifeant effect in assisting expectoration in patients with pulmonary infection and respiratory failure, which could help to control the infection, improve the pulmonary function and reduce ICU days. It is worthy to be popularized.
