Hypothermia is a common phenomenon in the perioperative period, and it affects 60 to 90% of patients submitted to anesthetic-surgical procedures. In order to minimize its incidence, warming methods are used. Such methods can be passive, such as orthopedic cotton, sheets and blankets, or active, such as warm-air blankets and thermal mattresses. In this scenario, the present study aimed at comparing two warming methods used in the intraoperative period. Patients submitted to abdominal surgery in the specialties of gynecology and gastric surgery from August to September 2010 were included in the study. After randomization, they were divided into two groups: one using a thermal blanket (group I) and one using orthopedic cotton (group II). At last, 9 patients were included. The variables for each question were considered according to occurrence frequency. Comparison between groups was performed by Student’s t test. With the purpose to analyze whether there was an association, the chi-square test or Fisher’s Exact test was used. Whenever it was applicable for multiple comparisons, Tukey’s test was utilized; p values < 0.05 were considered to be statistically significant for analysis. The sample comprised 6 males and 3 females submitted to gynecological and gastric surgeries. Their mean age was 48 years for group I and 46.2 years for group II. A predominance of general anesthesia was observed. The time of permanence in the operating room ranged from 80 to 360 minutes. With regard to warming parenteral solutions, the procedure was performed on 5 patients, and infusion of warm solution into the abdominal cavity was performed on 50% of the sample. Concerning the warming method used, 5 patients used a thermal blanket. In view of the results presented, it was not possible to conclude which warming method should be used due to sample size
