Abstract [Objective]To explore the influence of the temperature of carbon dioxide(CO2 )gas on the re-covery of patients after laparoscopic gastrointestinal operation.[Methods]Totally 125 patients after laparo-scopic gastrointestinal operation were divided into 2 groups.In the experimental group(n=62),pneumoper-itoneum was established with CO2 gas heated to 37℃.In the control group(n=63),pneumoperitoneum was established with routine method.Body temperature before and after operation,tracheal extubation time,anal exhaust time and gastric extubation time in two groups were observed.Numerical rating scale(NRS)was used to evaluate the pain of surgical wound.[Results]There was no significant difference in body temperature be-fore operation between two groups (P>0.05).After operation,body temperature in the experimental group was obviously higher than in the control group(P<0.05).The tracheal extubation time,anal exhaust time, gastric extubation time and wound pain score in the experimental group were obviously lower than those in the control group,and there was significant difference(P<0.05).The incidence of postoperative complications was compared between two groups.Chills occurred in 6 cases(9.7%)of experimental group,which were sig-nificantly lower than those of control group(35 cases,55.6%),and there was significant difference between two groups(P<0.05).Gastrointestinal dysfunction occurred in 7 cases(11.3%)of experimental group, which were significantly lower than those of control group(26 cases,41.3%),and there was significant differ-ence between two groups(P<0.05).[Conclusion]Pneumoperitoneum established by CO2 gas heated to 37℃can promote the recovery of patients after laparoscopic gastrointestinal surgery.
