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),but there was no significant difference in endoscopy withdrawal time between the two groups (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),but the PaCO2 between the two groups showed no significant difference (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),but they were not 12h and 24h after the examination (P>0.05).Conclusion CO2 is safe and could reduce abdominal discomfort after colonoscopy,which is suit-able for clinical application.
