Comparison Between Non-invasive Heat-flux and Invasive Core Temperature Monitoring
- Conditions
- Body Temperature Changes
- Registration Number
- NCT03368040
- Lead Sponsor
- University Hospital, Bonn
- Brief Summary
The body core temperature drops during general anesthesia. To maintain homeostasis, patients require warming measures. Different methods to measure body core temperature exist, which are either highly accurate but invasive, or non-invasive but non-accurate. A new monitoring device, Tcore(TM), enables a non-invasive but accurate core temperature assessment.
This study is performed to quantify accuracy and bias of the Tcore system in comparison with the blood temperature, which is the gold standard of core temperature measurement.

- Primary Outcome Measures
Name Time Method Bias of heat-flux temperature monitoring [%] from insertion of thermometers to end of surgery Over the time course of surgery, the body core temperature is actually measured in the bloodstream (Tbl) and estimated by the heat-flux thermometer (Thf). The bias or median prediction error (MPE) is calculated as median of PE, which is (Tbl-Thf)/Tbl.
- Secondary Outcome Measures
Name Time Method Inaccuracy of heat-flux temperature monitoring [%] from insertion of thermometers to end of surgery Over the time course of surgery, the body core temperature is actually measured in the bloodstream (Tbl) and estimated by the heat-flux thermometer (Thf). The inaccuracy or median absolute prediction error (MAPE) is calculated as median of abs(PE), which is (Tbl-Thf)/Tbl.
