Previous studies have shown that ultrasonography (USG), as an alternative to radiography, has a good accuracy in confirming nasogastric tube (NGT) position. Color flow detection of air insufflation is a novel approach in verifying NGT position. In our study, we aimed at evaluating its sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy in confirming the NGT position, as compared with 2-dimensional (2D) USG. ⋯ Color flow detection of air insufflation improves the diagnostic accuracy of ultrasound in verifying NGT position. It is a quick investigation such that fasting time of patients and their length of ED stay can be shortened.
