Comparison of Nasopharyngeal Temperature Measured at Fossa of Rosenmuller and Blindly Inserted Temperature Probe with Esophageal Temperature: A Cross-Sectional Study.

Introduction: Monitoring body temperature and maintaining normothermia are now essentially the standard-of-care during anesthesia. This study was designed to compare the temperature measured by nasopharyngeal temperature probes inserted by landmark method and fiberscope-guided method with esophageal temperature. We hypothesized that placing the temperature probe at the level of fossa of Rosenmuller will reflect core temperature as it is in close relationship to the brain.
