| description | Background Body temperature monitoring is essential during the perioperative period. However, core body temperature measurement requires invasive device that may cause complications. This study aimed to evaluate the accuracy of non-invasive Bair Hugger™ core body temperature monitoring system (BHTMS) at the wrist compared with esophageal temperature under general anesthesia. Methods Twenty adult patients of the American Society of Anesthesiologists physical status I or II were enrolled. BHTMS sensor was applied at wrist region. After tracheal intubation, an esophageal probe was inserted. Bair Hugger™ upper body warming blankets were used. Esophageal temperature (Teso) and BHTMS at wrist (Twrist) were recorded every 10 min. Results Total of 257 pairs of data sets were analyzed: Teso and Twrist had no statistically significant difference (P = 0.103). Median of Teso and Twrist were 36.5℃ and 36.4℃. Bland-Altman analysis showed Teso – Twrist of 0.14℃ ± 1.44. Subsequently, 99 pairs of 0–40 min data set were analyzed and showed significant difference at 0 and 10 min (P < 0.001) but no significant difference at 20, 30 and 40 min. Bland–Altman plot by times showed difference (Teso - Twrist) of 1.49℃ ± 2.00, 0.82℃ ± 1.30, 0.29℃ ± 1.32, –0.03℃ ± 0.84, and –0.12℃ ± 0.82 at 0, 10, 20, 30 and 40 min respectively. Conclusions BHTMS at wrist area under the upper body warming blanket is a potential alternative other than esophageal temperature for monitoring body temperature after 30 min of anesthesia induction. |
