Objective:To discuss the effects of five-element music & Chinese Medicine gut purging exercise in bowel preparation for patients of colonoscopy.Methods:146 patients preparing for routine colonoscopy are randomly divided into 2 groups:73 patients in observation group,73 patients in control group.Patients in the control group used PEG-ELS for bowel preparation;patients in the observation group used five-element music and Chinese Medicine gut purging exercise.The stress reactions of patients were observed in both groups,as well as the quality of bowel preparation,adverse reactions and patients'endurance to bowel preparation.Results:After bowel preparation,and 5 min before endoscopy check,systolic pressure,diastolic pressure and heart rate of patients in observation group were lower than those in control group(t value:3.214,3.085,4.216).Quality score of preparation of right hemicolon,colon transversum,left hemicolon was higher than those of patients in control group(Z value:-2.997,-2.338,-2.551,-2.939).The total scores of nausea,vomiting,abdominal pain,distension and adverse reactions were lower than those of control group(Z value were-2.392,-2.023,-3.197,-3.368,respectively),and bowel preparation endurance was higher than that of control group(x2value was 9.505),the differences were statistically significant(P<0.05).There was no significant difference in general fatigue,palpitation and cold sweat between the two groups(P>0.05).Conclusion:Five-element music and Chinese Medicine gut purging exercise can reduce the stress response of patients for bowel preparation,improve the quality of bowel preparation and improve patient's tolerance for bowel preparation.
