ABSTRACT
Objective To explore the application of CO2 as an insufflation agent in patients under-going colonoscopy by comparing carbon dioxide(CO2 )and air.Methods Consecutive 681 patients who un-derwent conventional colonoscopy from January to May in 2014 at endoscopy center of our hospital were in-cluded.The patients were randomly divided into the air group and CO2 group.The gas flow,capacity,oper-ation time,PaCO2 and abdominal pain during and 20 min,40 min,1 h,2 h,12 h,24 h after colonoscopy were recorded.The safety and advantages of CO2 in the colonoscopy were analyzed.Results The intubation time of CO2 group was significantly shorter than that of air group (P 0.05).There was also no difference in air flow and the total volume between the two groups (P >0.05).PaCO2 of two groups were within the nor-mal range.PaCO2 during examination was significantly higher than that before and 20 minutes after examina-tion (P 0.05).The abdominal pain scores during and 20 min,40 min,1 h,2 h after the examination of air group were signifi-cantly higher than those of CO2 group (P 0.05).Conclusion CO2 is safe and could reduce abdominal discomfort after colonoscopy,which is suit-able for clinical application.
