ObjectiveTo investigate the effects of endoscopic direct spraying of compound alverine citrate on the intracolonic air bubbles in the colonoscopic examination, the colonoscopic examination time, and postoperative abdominal pain and distention. MethodsA total of 118 outpatients undergoing painless electronic colonoscopic examination were selected and randomly divided into a study group or a control group, with 59 patients in each group. Both groups received routine bowel preparation before the operation. During the colonoscopic examination, the study group used the spray of compound alverine citrate, while the control group used a normal saline spray, according to the visual field condition. The colonic cleanliness before spraying, intracolonic bubbles grade after spraying, colonoscopic examination time, intraoperative spray amount, and abdominal pain and distension within 24 hours after the operation were compared between the two groups. ResultsThere was no statistically significant difference in the Boston Bowel Preparation Scale score between the two groups before spraying (P＞0.05). Compared with the control group, the study group had better intracolonic bubble grade after spraying, shorter colonoscopic examination time, less intraoperative spray amount, and lower Visual Analogue Scale score for abdominal pain and incidence of abdominal distension within 24 hours after the operation (all P＜0.05). ConclusionDuring the colonoscopic examination, endoscopic direct spraying of compound alverine citrate can effectively remove bubbles, improve visual field clarity, shorten colonoscopic examination time, alleviate postoperative abdominal pain and distention, and improve the comfort of colonoscopic examination, which is worthy of clinical promotion and application.
