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.

Comparative Study
Comparison of tranexamic acid plasma concentrations when administered via intraosseous and intravenous routes.
There is a lack of information regarding intraosseous (IO) administration of tranexamic acid (TXA). Our hypothesis was that a single bolus IO injection of TXA will have a similar pharmacokinetic profile to TXA administered at the same dose IV. ⋯ The results of this study support pharmacokinetic bioequivalence of IO and IV administration of TXA.

Despite the low diagnostic yield of echocardiogra0, it is often used in the evaluation of syncope. This study determined whether patients without abnormalities in the initial evaluation benefit from transthoracic echocardiogram (TTE) and the clinical factors predicting an abnormal TTE. ⋯ A patient who is older than 59years or has an abnormal ECG or an elevated BNP level may benefit from TTE. Otherwise, TTE should be deferred in patients with no risk factors in the initial evaluation.
