Abstract:
Core temperature (T Core ) monitoring is essential in intensive care medicine. Bladder temperature is the standard of care in many institutions, but not possible in all patients. We therefore compared core temperature measured with a zero-heat flux thermometer (T ZHF ) and with a bladder catheter (T Bladder ) against blood temperature (T Blood ) as a gold standard in 50 critically ill patients in a prospective, observational study. Every 30 min T Blood , T Bladder and T ZHF were documented simultaneously. Bland–Altman statistics were used for interpretation. 7018 pairs of measurements for the comparison of T Blood with T ZHF and 7265 pairs of measurements for the comparison of T Blood with T Bladder could be used. T Bladder represented T Blood more accurate than T ZHF . In the Bland Altman analyses the bias was smaller (0.05 °C vs. − 0.12 °C) and limits of agreement were narrower (0.64 °C to − 0.54 °C vs. 0.51 °C to – 0.76 °C), but not in clinically meaningful amounts. In conclusion the results for zero-heat-flux and bladder temperatures were virtually identical within about a tenth of a degree, although T ZHF tended to underestimate T Blood . Therefore, either is suitable for clinical use. German Clinical Trials Register, DRKS00015482, Registered on 20th September 2018, http://apps.who.int/trialsearch/Trial2.aspx?TrialID=DRKS00015482 .
