Abstract
Accurate measurement of body temperature is crucial post-cardiovascular surgery, given the intricate and high-risk nature of cardiovascular procedures. In this prospective observational study, the safety and efficacy of infrared tympanic thermometers (ITT) and non-contact infrared temporal artery thermometers (NCTAT) were assessed in intensive care patients recovering from cardiovascular surgery. Conducted at a state hospital in Istanbul from April to July 2016, the study included 60 eligible patients meeting the specified criteria. Results indicated a slightly higher body temperature measurement with ITT (36.42±0.72) compared to NCTAT (36.02±0.79). NCTAT and ITT values were found (right ear: bias =0.39°C, limits of agreement: -1.99°C to 1.21°C; left ear: bias =0.29°C, limits of agreement: -1.59°C to 1.01°C) in the statistical evaluation by Bland and Altman analysis method. Repeatability, intragroup correlation and scatter plots of both measuring devices did not show a significant difference. In conclusion, within the cardiovascular surgical intensive care unit, both types of thermometers prove suitable for body temperature measurement. Healthcare professionals can make informed choices between the two based on the distinct advantages and disadvantages associated with each device.
