Esophageal, tympanic, rectal, and skin temperatures in children undergoing surgery with general anesthesia.
The purpose of this study was to determine the degrees of agreement between various sites of temperature measurement and examine the trend of body temperature in children during surgery under general anaesthesia. Thirty-six consecutive children who underwent surgery with general anaesthesia, had temperatures measured at the oesophagus, skin, ear canal and rectum at baseline, every 15 minutes for the first hour and every 30 minutes thereafter. Spearman correlation and Bland-Altman analyses were used to compare data and trends of mean differences assessed by line graphs. ⋯ Bland-Altman plots showed that the least difference (bias) at baseline (0.3°C) was between the oesophageal and tympanic temperatures while at 1 hour (0.13°C ) was between the oesophageal and rectal temperatures. The oesophageal site was the closest to rectal for monitoring core temperature while the skin was the least reliable site in the study population. In the situation where oesophageal probe is not routine or functioning, rectal or tympanic temperatures may be used.

Agreement between temporal artery, oral, and axillary temperature measurements in the perioperative period.
This study examined agreement in temperature readings preoperatively and postoperatively between temporal artery and electronic oral/axillary thermometers as well as the seconds required to obtain temperature readings across the three measuring modes. Using a repeated measures design, 86 adult subjects had temporal artery, oral, and axillary temperatures taken upon admission to the surgical area and upon admission to the PACU. ⋯ Seconds to temperature measurement was significantly different both preoperatively and postoperatively, with temporal artery measurement the fastest, followed by oral and then axillary. Results support the use of the temporal artery thermometers as an alternative for perioperative noninvasive temperature monitoring.
