摘要

Study Objectives

To determine whether the covering of healthy children during anesthetic induction reduces hypothermia at the end of minor surgeries.

Design

Randomized, single-blinded, prospective study.

Setting

Operating room and postoperative recovery area of a university-affiliated hospital.

Patients

50 ASA physical status 1 patients, aged 6 months to 3.5 years, scheduled for simple urological surgeries.

Interventions

Subjects were randomly assigned to one of two groups: covered or uncovered. Children in the covered group (Group C) were actively warmed on arrival in the operating room (OR) using cotton blankets and a warm forced-air blanket set at 43掳C. Children in the uncovered group (Group U) remained uncovered during the induction of general anesthesia. Children in both groups were actively warmed following placement of surgical drapes.

Measurements

Temperature (in Celsius) during the study procedure was recorded for each patient.

Main Results

Mean core body temperature at the end of induction did not differ in the two groups, 36.4掳C in Group C and 36.6掳C in Group U. Mean core body temperature at the end of surgery did not differ between the two groups: 36.9掳C in Group C and 37.0掳C in Group U.

Conclusion

Leaving healthy children uncovered during induction of general anesthesia does not have a clinically significant effect on core temperature at the end of induction or of surgery.
