Correlation of Intraoperative Recordings from a Forehead Mounted Liquid Crystal Thermometer and Esophageal Thermistor.
Abstract
This study evaluated the performance of a liquid crystal temperature device during general anesthesia. Eighteen patients undergoing general anesthesia were the study population. After obtaining informed consent, the liquid crystal device was placed on the patient's forehead in the holding area. Patients were brought to the OR suite where general anesthesia was induced via IV technique and maintained with Isoflurane and N2O or Desflurane and N2O. An esophageal stethoscope/thermistor was placed shortly after induction of anesthesia for temperature assessment and correlation with the recordings of the liquid crystal device. One hundred and ninety temperature comparisons were recorded. Statistical analysis using Pearson's correlation coefficient gave an R= .653 significant at the p< .01 level. The forehead mounted liquid crystal thermometer appears to be comparable to intraoperative temperature recordings with that of the esophageal thermistor.
