Abstract

Nursing
Temperature measurement in an intensive care environment requires accurate estimation of core temperature via reliable equipment. Intermittent rectal probes were routinely used to measure core temperature in all extubated patients admitted to the Intensive Care Unit (ICU) which was the setting for this project. The nursing and medical staff identified various problems associated with this practice and a quality improvement project was implemented to compare temperatures recorded using three different routes: rectal, infrared tympanic and nasopharyngeal. Forty-nine patients were included in the study. Nasopharyngeal temperature measurements were recorded for all intubated patients and rectal temperature measurements were recorded for all extubated patients. During data collection, infrared tympanic temperature measurements were recorded at the same time as all other temperature measurements. The main comparison was between the rectal route and the infrared tympanic route because of the problems with the rectal probes that had been identified by staff. The results indicated statistically significant correlations between temperatures measured at the different sites. These results confirmed previous literature and the ICU involved in this study replaced rectal temperature measurement via intermittent probe insertion with infrared tympanic thermometry for the measurement of core temperature in extubated patients.
