Objective To investigate the effect of open surgery versus laparoscopic carbon dioxide pneumoperitoneum on nasopharyngeal temperature.Methods A total of 96 patients who underwent an elective abdominal surgery in our hospital from January 2020 to June 2021 were included as the research objects.They were divided into the open surgery group and laparoscopy group according to different surgical methods,with 48 cases per group.The nasopharyngeal temperature,recovery time,norepinephrine and epinephrine levels,and the incidence of agitation,shivering and hypothermia were compared between groups.Results At the beginning of the surgery,there was no significant difference in nasopharyngeal temperature between the two groups(P>0.05).The nasopharyngeal temperature in laparoscopy group was significantly higher at 1h,2h of surgery and at the end of the surgery than that of open surgery group(P<0.05).The recovery time of open surgery group was significantly shorter than that of laparoscopy group(P<0.05).At the beginning of the surgery,there were no significant differences in norepinephrine and epinephrine levels between groups(P>0.05),which,at 2h of surgery and at the end of the surgery,were significantly lower in the open surgery group than those of laparoscopy group(P<0.05).The incidences of agitation,shivering and hypothermia were significantly lower in the open surgery group than those of laparoscopy group(P<0.05).Conclusion Compared with open surgery,carbon dioxide pneumoperitoneum in laparoscopic surgery is more likely to lead to hypothermia.
