穴位贴敷时长与支气管哮喘疗效的相关性探讨

Relative Effect of Bronchial Asthma with Acupoint Application Related to Application Length

目的:观察基于"冬病夏治"理论穴位贴敷防治支气管哮喘的临床疗效,并探讨贴敷时长与疗效的关系。方法:收集126例处于缓解期的支气管哮喘患者,依据贴敷时长的不同,按随机数字表分为4 h组、6 h组、8 h组和10 h组,用中药膏贴贴敷,取双侧肺俞穴、膈俞穴等,从夏至第1天开始贴敷治疗,每7天贴敷1次,总贴敷8次。记录4组哮喘患者治疗前及治疗结束1年后的喘息(分)、哮鸣音(分)、哮喘年发作次数(次/年)情况。结果:治疗后4 h组疗效差于其它3组(P<0.05),6 h组疗效与8 h组、10 h组比较差异有统计学意义(P<0.05),8 h组与10 h组疗效比较差异无统计学意义(P>0.05)。4组患者治疗后临床症状积分均下降(P<0.05)。对4组患者治疗后临床症状组间进行比较,4 h组、6 h组各项指标的改善差于8 h组、10 h组(P<0.05),8 h组与10 h组各项指标比较差异无统计学意义(P>0.05)。结论:冬病夏治穴位贴敷是防治哮喘的一种有效方法,随贴敷时长的增加,疗效也显著提高,但当贴敷时长达到一定范围时,疗效不再随贴敷时长的延长而增加,贴敷时长为8 h防治效果达到最佳。

Objective： To observe the clinical effect of acupoint application based on＂winter disease and summer treatment＂to prevent and treat bronchial asthma,and to explore the relationship between application length and curative effect. Methods： 126 bronchial patients at remission stage were randomly divided into the 4 h group,the 6 h group,the 8 h group and the 10 h group. Ointment patches were used to BL 13 and BL17 from the beginning of the Summer Solstice,the application was done once a week for eight continuous times. The breathing scores,wheezing scores,seizure frequency per year were recorded before and after one-year treatment among four groups. Results： The effect of the 4 h group was worse than the other three groups（P〈0. 05）,among which,the 6 h group,the 8 h group,and the 10 h group have statistically difference（P〈0. 05）,wheareas the 8h group and the 10 h group have no statistically difference（P〉0. 05）. The scores of clinical symptom decreased in all four groups after treatment（P〈0. 05）,among which the indicators improvement of the 4 h group and the 6 h group were worse than the 8 h group and 10 h group（P〈0. 05）,but there was no significant difference between the 8 h group and the 10 h group（P〉0. 05）. Conclusion： Acupoint application is an effective method for the prevention and treatment of asthma. The curative effect is increased along with the increased application length. However,the effect will not be further increased when the length arrived at eight hours.
