3. Results
A total of 115 patients were enrolled, 58 assigned to prewarming
group and 57 to the control group. Seven patients
elected to discontinue the study (3 in prewarming group and
4 in non-prewarming group). Because of surgeon preference
and surgical procedure requirements, 6 patients (4 prewarming
and 2 non-prewarming) were unable to receive intraoperative
warming and were therefore excluded from the analysis. The
final analysis thus included 102 patients (Fig. 1).
Baseline and intraoperative factors were balanced between
the randomized groups (ie, absolute standardized difference
b0.39), except that prewarmed patients were more likely to
have been intubated (Table 1).
