中药穴位贴敷对中风后便秘的预防效果研究

【目的】探讨中药穴位贴敷预防中风后便秘的临床效果。【方法】采用随机双盲对照的研究设计方案，将96例中风阳类证患者随机分为观察组和对照组各48例。2组患者均在中风疾病治疗的基础上进行预防便秘的常规护理，对照组给予安慰剂穴位贴敷治疗，观察组给予自制的大黄芒硝敷脐贴穴位贴敷治疗。观察2组患者便秘发生率、使用缓泻剂及不良反应情况。【结果】（1）经干预后，观察组在第7天、第14天的便秘发生率均低于对照组（P＜0.05或P＜0.01）。（2）干预后第7天和第14天，观察组的Bristol大便性状评分均较干预前显著提高（P＜0.05），而对照组提高不明显（P＞0.05），观察组在改善大便性状方面优于对照组（P ＜0.05）。（3）观察组使用缓泻剂的例次较对照组显著减少，差异有统计学意义（P＜0.05）。（4）对照组的不良反应发生率为6.25%，观察组为8.33%，差异无统计学意义（P＞0.05）；且所有患者的不良反应症状均较轻，未有中止治疗者。【结论】中药穴位贴敷预防中风后便秘效果好，操作简单且安全。

Preventive Effect of Acupoint Application of Chinese Medicine on Post-stroke Constipation

Objective To observe the effect of acupoint application of Chinese medicine on preventing constipation after stroke. Methods By means of randomized, double-blind, controlled study design, 96 patients of yang-syndrome stroke were randomly divided into observation group and control group, 48 cases in each group. Both groups were given conventional treatment for stroke and routine nursing for preventing constipation, and additionally, the control group was given acupoint application of placebo while the observation group was given acupoint application of self-made umbilical paste of Radix et Rhizoma Rhei(Dahuang) and Natrii Sulfas (Mangxiao). The incidence of constipation, frequency of laxative usage and adverse reactions of the two groups were observed. Results (1) The incidence of constipation of the observation group was lower than the control group on treatment day 7 and 14 , the difference being statistical significant(P < 0.05 or P < 0.01).(2)On treatment day 7 and 14, the Bristol scores of stool properties of observation group were increased compared with those before treatment(P < 0.05), but the changes of scores in the control group were insignificant(P > 0.05). The observation group had better effect on improving stool properties(P < 0.05).(3) The frequency of use of laxatives was reduced in the observation group compared with the control group, the difference being significant(P<0.05).(4) The incidence of adverse reaction was 6.25%in the control group and was 8.333%in the observation group, the difference being insignificant (P>0.05). The adverse reaction of both groups was mild, and had no effect on the accomplishment of the treatment. Conclusion Acupoint application of Chinese medicine is effective and safe on preventing constipation after stroke, showing good prospects for clinical application.
