OBJECTIVE: To assess the safety and efficacy of @entity544 ( @entity515 ) in colonoscopy examination. METHODS: We randomized 349 @entity1 to undergo colonoscopy with insufflation of air (n=175) or @entity515 (n=174). At colonoscopy, p (ET @entity515 ) was observed at 4 time points: before the exam, arrived caecum, back rectum, and after the exam. @entity1 's experience of @entity158 in the end and after the examination at 1, 3, 6, and 24 h was registered using a visual analog scale (VAS). Sedation was not used routinely. RESULTS: The groups were similar in age, sex, inspection time, and caecal intubation rate (all P>0.05). There were no significant differences in p (ET @entity515 ) values between the 2 groups before and after the procedure (all P>0.05). VAS scores in the @entity515 group at various time points after the examination were significantly lower than those in the air group (all P<0.05). The percent of VAS scores of 0 in the @entity515 group after 1, 3, 6, and 24 h was significantly higher than that in the air group (all P<0.01). CONCLUSION: Injection of @entity515 for colonoscopy will not cause @entity515 retention, and it may significantly reduce the @entity158 , which is safe and effective.
