SUMMARY Perioperative hypothermia could produce multiple adverse effects. The aim of this study is to evaluate the benefits of a passive method of body heat conservation; a plastic cover with an air chamber and refractory aluminium surface to prevente hupothermia in otolaryngological surgery. 20 aleatorized patients were divided in 2 groups : the control and the cover group. Central body temperature was measured with a tympanic thermometer previous to the induction, postinduction phase, at the time of arrival at the recovery room; and every 15 minutes until normothermia was reached. Postoperative shiver was registered. 3 patients had hypothermia in the postinduction phase, 2 in the control group and 1 in the cover group. At the recovery room 11 patients developed hypothermia, 7 in the control group and 4 in the cover group. Althoug tympanic temperature in patients in the cover group at postinduction phase and at the recovery room was greater than in the control group, the difference was no statisticallysignificance (p>0.05). The incidence of hypothermia in the cover group was lower than in the other one, althoug that has no statistically significancy (p=0.369) We conclued that our evaluation of the cover method was not effective for the prevention of hypothermia.
