Aykanat VM, et al. - To ascertain the dependability of two frequently employed temperature measurement devices, forehead temporal artery temperature and tympanic measurement, in addition to an indwelling urinary catheter with temperature probe, vs the final nasopharyngeal core temperature at the end of surgery, researchers undertook this prospective analysis of 100 patients. Correct detection of only 54% of hypothermic cases was enabled by the forehead measurement device. Findings revealed the imprecision as well as the non-reliability of two frequently employed temperature measurement devices, forehead temporal artery temperature and tympanic measurement, vs nasopharyngeal core temperature, after major surgery. However, the indwelling catheter with temperature sensor affords an accurate as well as acceptable tool for continuous core temperature measurement in the post‐anaesthesia care unit.
