Abstract
Hypothermia is common occurrence in patients undergoing colonic surgeries. We hypothesized that the underbody forced air warming blankets will be better than conventional over-body forced air warming blankets for prevention of hypothermia during laparoscopic colon surgeries. After ethics approval, sixty patients undergoing elective laparoscopic colon surgeries were randomly divided into two groups to receive warming by underbody forced air warming blanket (n = 30) or over-body forced air warming blanket (n = 30). In the operating room, epidural catheter was inserted and thereafter warming was started with the forced air warmer with temperature set at 44 °C. Intraoperatively core temperature (using nasopharyngeal probe), vitals, incidence of postoperative shivering and time to reach Aldrete Score of 10 in the postoperative period were recorded. The core temperature was higher with an underbody blanket at 60 min (36.1 ± 0.5 °C vs. 35.7 ± 0.5 °C, P = 0.005), 90 min (35.9 ± 0.5 °C vs. 35.6 ± 0.5 °C, P = 0.009), 120 min (35.9 ± 0.5 °C vs. 35.5 ± 0.4 °C, P = 0.007), and 150 min (35.9 ± 0.5 °C vs. 35.6 ± 0.4 °C, P = 0.011). In the post anesthesia care unit, the time to reach an Aldrete score of 10 was also less in the underbody blanket group (14.3 ± 2.5 min vs. 16.8 ± 3.6 min) (P = 0.003). However, there were no clinically meaningful differences in any outcome. Underbody and over-body blankets were comparably effective in preventing hypothermia in patients undergoing laparoscopic colorectal surgery under general anaesthesia.
