Abstract

PURPOSE
The purpose of this study was to compare the effects of 21℃ CO₂ and 37℃ CO₂ pneumoperitoneum on body temperature, blood pressure, heart rate, and acid-base balance.
METHODS
Data were collected at a 1300-bed university hospital in Incheon, from February through September 2012. A total of 74 patients who underwent laparoscopic colectomy under general anesthesia with desflurane were randomly allocated to either a control group or an experimental group. The control group received 21℃ CO₂ pneumoperitoneum; the experimental group received 37℃ CO₂ pneumoperitoneum. The pneumoperitoneum of the two groups was under abdominal pressure 15 mmHg. Body temperature, systolic blood pressure, heart rate and acid-base balance were assessed at 30 minutes and 90 minutes after pneumoperitoneum, and again at 30 minutes after arriving at the Post Anesthesia Care Unit.
RESULTS
Body temperature in the 37℃ CO2 pneumoperitoneum group was significantly higher (F=9.43, p<.001) compared to the 21℃ CO₂ group. However, there were no statistically significant differences in systolic blood pressure (p=.895), heart rate (p=.340), pH (p=.231), PaCO₂ (p=.490) and HCO3- (p=.768) between the two groups.
CONCLUSION
Pneumoperitoneum of 37℃ CO₂ is effective for the increase of body temperature compared to pneumoperitonium of 21℃ CO₂, and it does not result in a decrease of blood pressure, heart rate or acid-base imbalance.
