慢性阻塞性肺疾病合并肺部感染患者使用高频胸壁振荡排痰仪排痰的效果观察

Effects of high-frequency chest wall oscillatory device on sputum excretion in patient with chronic obstructive pulmonary disease accompanied by pulmonary infection

目的探讨慢性阻塞性肺疾病合并肺部感染患者使用高频胸壁振荡排痰仪排痰的效果。方法慢性阻塞性肺疾病合并肺部感染患者80例分为振动组和振荡组,各40例。振动组患者采用振动排痰仪排痰,振荡组采用高频胸壁振荡排痰仪排痰。观察2组患者治疗后1 d、3 d日排痰量,治疗前后心率、呼吸、血氧饱和度水平。结果振荡组治疗后1 d、3 d日排痰量均高于振动组,差异有统计学意义(P<0.01)。2组治疗后心率、呼吸差异无统计学意义(P>0.05)。振荡组治疗后血氧饱和度高于振动组,差异有统计学意义(P<0.01)。结论慢性阻塞性肺疾病合并肺部感染患者使用高频胸壁振荡排痰仪排痰的效果显著。

Objective To investigate the effects of high-frequency chest wall oscillatory de-vice on sputum excretion in patient with chronic obstructive pulmonary disease （CO PD） accompa-nied by pulmonary infection. Methods A total o f 80 patients with COPD accompanied by pul-monary infection were assigned to the vibration group （n = 40） and the oscillation group （n - 40） , with vibration sputum elimination device and high-frequency chest wall oscillatory device re-spectively. The daily sputum volume at day 1 and day 3 after treatment were recorded. The heart r ate , respiratory rate and oxyhemoglobin saturation were compared between two groups. Results The sputum volume was higher in the oscillation group than that of vibration group at day 1 and day 3 after treatmen t, with significant difference （ P 〈0.01）. There was no significant difference in heart rate and respiratory rate between two groups after treatment （P 〉0. 05）. The oxyhemo-globin saturation was higher in the observation group than that of co n trols, with a significant difference （P 〈 0. 01） . Conclusion High-frequency chest wall oscillatory device is effective in sputum excretion for patients with COPD accompanied by pulmonary infection.
