目的观察负压温吸理疗对支气管哮喘患者最大呼气流量 (Peakexpiratoryflow ,PEF)的影响及其临床疗效。方法 97例轻中度急性发作哮喘患者随机分为溴化异丙托品吸入对照组和负压温吸理疗加溴化异丙托品吸入治疗组 ,于治疗前及治疗后 30分钟 ,1,2 ,3,4小时分别测定PEF值 ,并判断其临床疗效。结果治疗组和对照组的有效率分别为 90 2 %和 71 7% (P <0 0 5 ) ,PEF峰值时间分别为治疗后 2小时 (4 48 4± 5 3 1L/min)和 1小时 (4 10 7± 48 1L/min) ,4小时内PEF增量百分比(△PEF % )分别为 2 7 9± 8 8%和 17 6± 7 5 % (P <0 0 1)。结论负压温吸理疗有一定的支气管扩张作用 ,可作为支气管哮喘治疗的一种辅助手段。
Objective To observe the effect of negative pressure warm-suction therapy on the maximum expiratory flow (PEF) in patients with bronchial asthma and its clinical efficacy. Methods A total of 97 patients with mild-to-moderate acute asthma were randomly divided into two groups: inhaled ipratropium bromide control group and vacuum temperature inhalation therapy plus ipratropium bromide inhalation group. Before and 30 minutes after treatment, 2, 3,4 hours were measured PEF values, and determine the clinical efficacy. Results The effective rates of treatment group and control group were 90 2% and 71 7% respectively (P 0 05). The peak time of PEF was 2 484 ± 5 3 1 L / min and 1 hour after treatment respectively 4 10 7 ± 48 1L / min), PEF% increase within 4 hours were 279 ± 8 8% and 17 6 ± 7 5%, respectively (P 0 01). Conclusion Negative pressure thermotherapy has certain bronchodilator effect, which can be used as an adjunct to bronchial asthma therapy.
