Abstract
Perioperative hypothermia is still common and has relevant complication for the patient. An effective perioperative thermal management requires essentially an accurate method to measure core temperature. So far, only one study has investigated the new Temple Touch Pro™ (Medisim Ltd., Beit-Shemesh, Israel). during anesthesia Therefore, we assessed the agreement between the Temple Touch Pro™ thermometer (TTP) and distal esophageal temperature (TEso) in a second study. After approval by the local ethics committee we studied 100 adult patients undergoing surgery with general anesthesia. Before induction of anesthesia the TTP sensor unit was attached to the skin above the temporal artery. After induction of anesthesia an esophageal temperature probe was placed in the distal esophagus. Recordings started 10 min after placement of the esophageal temperature probe to allow adequate warming of the probes. Pairs of temperature values were documented in five-minute intervals until emergence of anesthesia. Accuracy of the two methods was assessed by Bland-Altman comparisons of differences with multiple measurements. Core temperatures obtained with the TTP in adults showed a mean bias of -0.04 °C with 95% limits of agreement within - 0.99 °C to + 0.91 °C compared to an esophageal temperature probe. We consider the TTP as a reasonable tool for perioperative temperature monitoring. It is not accurate enough to be used as a reference method in scientific studies, but may be a useful tool especially for conscious patients undergoing neuraxial anesthesia or regional anesthesia with sedation. Trial registration This study was registered in the German Clinical Trials Register (DRKS-ID: 00024050), day of registration 12/01/2021.

55 patients who underwent RALP from March 2019 to October 2019. Room temperature conditions were controlled between 24°C and 26°C, and pharyngeal temperature and TTP were measured simultaneously during RALP. A total of 10 points were extracted at the beginning of surgery, at the start of head lowering, every 30 minutes from the start of head lowering to 180 minutes, at the end of head lowering, and at the end of surgery, in order to compare the two temperature sets by calculating the mean value with the Wilcoxon test. The number of occurrences was compared using the χ-square test, with values below 35°C at each point of measurement as outliers.

It was a prospective method comparison study. Core body temperature was measured by TTP and RSP temperature probe (eardrum temperature) manufactured by Smiths medical.

Positive end-expiratory pressure (PEEP) causes carotid baroreceptor unloading, which leads to thermoregulatory peripheral vasoconstriction. However, the effects of PEEP on intraoperative thermoregulation in the prone position remain unknown.

The present study aimed to compare a range of cooling methods possibly utilised by occupational workers, focusing on their effect on body temperature, perception and manual dexterity.

To compare rectal temperature and core temperature measured by TTP during general anesthesia in pediatric patients.

The Temple Touch Pro (TTP) is a novel system that estimates core temperature from skin over the temporal artery. We tested the hypothesis that this noninvasive system estimates core temperature to an accuracy within 0.5°C.

Monitoring peri-operative body temperature in children is currently mainly achieved through invasive devices. The Temple Touch Pro Temperature Monitoring System estimates core temperature noninvasively based on heat flux thermometry.

Objective: To investigate the agreement of this noninvasive sensor against standard oesophageal core temperature.

During general anesthesia, human body easily reaches a hypothermic state, which is mainly caused by heat redistribution. Most studies suggested that humidified heated breathing circuits (HHBC) have little influence on maintenance of the core temperature during early phase of anesthesia. This study was aimed at examining heat preservation effect with HHBC in case of undergoing surgery with less exposure of surgical fields and short surgical duration.
