Description
Background: The goal of this project is to improve the accuracy of temperature readings in the cardiac operating room and, in turn, improve patient safety.
Methods: The project obtained nasopharyngeal, tympanic, and bladder/rectal temperature measurements from twenty CPB cases. Measurements were obtained at six critical points: time of incision, initiation of CPB, aortic cross clamping, removal of aortic cross clamping, CPB termination, sternal closure. Data was analyzed to determine discrepancies among methods of measuring temperature for each type of probe utilized. Plan: Tympanic probes are unreliable and provide lower temperature measurements when compared to other probes Do: Temperatures recorded from different temperature probes Study: Tympanic measurements were negative 0.61 degrees Celsius on average Act: Perform additional studies with larger populations and include bypass circuit probes
Results: The average tympanic temperature measurements were consistently lower than nasopharyngeal temperature measurements for twenty pediatric cardiopulmonary bypass cases. The average difference was negative 0.61 degrees Celsius.
Conclusions: The data obtained suggests that tympanic probes are inferior to nasopharyngeal probes. Additional studies should be conducted with larger patient populations in order to confirm the findings of this quality improvement project. Additionally, it may prove beneficial to include bypass circuit temperature probes in evaluating future data
