Objective To evaluate the effect of visual and audiovisual distraction on anxiety and acceptance levels among patients undergoing colonoscopy. Methods A total of 180 consecutive patients undergoing colonoscopy were randomly divided into three groups: group A received visual distraction; group B received audiovisual distraction; and group C received routine care alone. Levels of anxiety and willingness to accept the same intervention if the procedure needed to be repeated were compared among the three groups. Results The reduction of anxiety score after colonoscopy in group A and group B was greater than that in group C, but the difference was not statistically significant. The rate of willingness to accept the same intervention if the procedure needed to be repeated was significantly different among the three groups: the rates for group A and group B were higher than for group C (Plt;0.05). Conclusions Both visual distraction and audiovisual distraction can significantly improve patients’ acceptance of colonoscopy. Visual distraction and audiovisual distraction have no significant effect on reducing anxiety.
Colonoscopy examination is the gold standard for diagnosis and treatment of colon diseases and screening for early cancer. Good quality of bowel preparation, which is also called intestinal cleanliness, is the prerequisite for full visualization of colonic mucosal lesions and their details. In clinic, more intestinal cleansing agents, such as polyethylene glycol and magneium suifate, have bad taste and high dosage, which can not be tolerated by some patients and affect the effect of bowel preparation. The use of oral adjuvant, add adjuvant to intestinal cleansing agents, new low-volume or very low-volume polyethylene glycol-ascorbic acid preparation methods, can reduce the incidence of adverse reactions, such as nausea and vomiting in patients, improve their tolerance, satisfaction and so on. This article reviews the methods of improving the taste and reducing the adverse reactions of intestinal cleansing agents at home and abroad to offer references for clinical practice.
