胸壁振动辅助治疗毛细支气管炎的临床效果观察

Effect of chest wall vibration therapy on bronchiolitis

目的观察应用胸壁振动辅助治疗毛细支气管炎的临床效果。方法将64例毛细支气管炎患儿随机分为胸壁振动组与药物对照组。比较2组患儿治疗前和治疗第3天血氧分压(PaO_2)、二氧化碳分压(PaCO_2)、血氧饱和度(SaO_2)、心率(HR)及呼吸(R)的变化,观察并分析排痰效果及住院时间。结果2组患儿治疗第3天,PaO_2、PaCO_2、SaO_2、HR和R均较治疗前有明显改善,差异有统计学意义(P<0.01);胸壁振动组各项指标的改善较药物对照组更明显,差异有统计学意义(P<0.01),且PaO_2和SaO_2达到正常范围。胸壁振动组吸痰时间和平均住院时间均明显较药物对照组短,差异有统计学意义(P<0.01)。结论应用胸壁振动辅助治疗毛细支气管炎可以改善患儿通气、换气功能和临床症状,缩短住院时间。

Objective To study the effect of chest wall vibration therapy on bronchiolitis. Methods A total of 64 patients with bronchiolitis were divided into an experimental group and a control group, the former included 34 cases and the latter included 30 cases. The experimental group received both routine treatment and chest wall vibration, while the control group only received routine treatment. PaO2 , PaCO2 , SaO2 , Heart Rate （HR） and Respiration （R） were observed, respectively, in the experimental group and the control group at the beginning and the end of the third day. Time needed for expectoration and length of hospital stay in the two groups were observed. Results It was shown that PaO2 , PaCO2 , SaO2 , HR, R were significantly improved at the end of the third day when compared with those at the beginning in both groups（ P 〈 0.01 ）. When comparing the results of PaO2, PaCO2 , SaO2, HR, R at the end of the 3rd day, it was shown that significant differences existed between the experimental group and the control group （P 〈0.01 ） , with the PaO2 and SaO2 reached the normal range in the experimental group. The time needed for expelling sputa and length of hospital stay of the experimental group were shorter than those of the control group （P 〈0.01 ）. Conclusion Chest wall vibration is particularly effective for treating bronchiolitis and can improve the function of aeration and ventilation.
