PS01.152: BODY TEMPERATURE IN THORACOSCOPIC ESOPHAGECTOMY AND AIR CONDITIONING SYSTEM OF OPERATION ROOM

Abstract Background It is well known that the perioperative hypothermia often cause the perioperative complications. In this study the hypothermia during the thoracoscopic esophagectomy and the relationship between the hypothermia and the air conditioning system of operation room were evaluated. Methods The subject of this study was 58 patients with esophageal cancer. Fifty of them were male and the others were female and the age was 65.2 + -8.4 years old. Forty three of 58 patients underwent the surgery in the old operation rooms (Group A) and 15 of them underwent it in the operation rooms with new air condirioning system (Group B). The 18 measuring points were picked up for each patient, which were from 10 to 180 minutes after start. The body temperatures were measured every 10 minutes after starting anesthesia. The temperature difference comparing with the starting point of surgery and the frequency of hypothermic state were evaluated. ‘Hypothermic state’ was defined that the temperature reduce more than 0.3 centigrade in comparison with the temperature at the starting point of surgery in this study. Results < 1 > The body temperature reduced early 60 minutes and then rose slowly. It reduce 0.22 + -0.35 centigrade at 60 minutes after starting surgery in comparison with the starting point of surgery. < 2–1 > The temperature of the patients in Group A reduced 0.24 + -0.03 centigrade and 0.32 + -0.09 centigrade at 30 and 60 minutes after starting surgery. But, the temperature of the patients in Group B reduced only 0.05 + -0.01 centigrade at 30 minutes after starting surgery and the temperature recovered at 60 minutes. These differences were statistically significant. < 2–2 > The total measuring points were 774 points in Group A and 270 points in Group B. The hypothermic state was observed 353 measuring points (45.6%) in Group A, and only 8 points (3.0%) in Group B. This difference was statistically significant. Conclusion The new operation rooms, in which the temperature of the air flow for the patients and that for surgeons can be set separately, is useful for keeping the body temperature of the patients adequately.
