Abstract: | We have evaluated the efficacy of new electric warming blankets, which meet
the requirements of the international standard for perioperative electrical
and thermal safety, in preventing intraoperative hypothermia. We studied 18
patients undergoing abdominal surgery, allocated to one of two groups: in
the control group, there was no prevention of intraoperative hypothermia (n
= 8) and in the electric blanket group, two electric blankets covered the
legs and upper body (n = 10). Anaesthesia duration was similar in the two
groups (mean 201 (SEM 11) min), as was ambient temperature (20.5 (0.1)
degrees C). Core temperature decreased during operation by 1.5 (0.1)
degrees C in the control group, but only by 0.3 (0.2) degree C in the
electric blanket group (P < 0.01). Five patients shivered in the control
group compared with one in the electric blanket group (P < 0.05). We
conclude that cutaneous warming with electric blankets was an effective
means of preventing intraoperative hypothermia during prolonged abdominal
surgery.
