Agreement between lower esophageal and nasopharyngeal temperatures in children ventilated with an endotracheal tube with leak

ConclusionsNasopharyngeal temperature accurately reflects lower esophageal temperature when there is minimal or no ETT leak. When a larger ETT leak is present, nasopharyngeal temperature is on average 0.1°C cooler than lower esophageal temperature. As the nasopharyngeal temperature probe site confers the advantage of simplicity of accurate placement compared to its esophageal counterpart, our findings support the use of nasopharyngeal temperature probes in children ventilated with both cuffed and uncuffed ETTs.
