The Use of Ultrasonography for Verifying Gastric Tube Placement in Newborns.

<bold>Background: </bold>The use of gastric tubes in newborns admitted to a neonatal intensive care unit is fairly high, and there is a risk of serious complications related to this procedure.<bold>Purpose: </bold>Considering the need to find a method that does not involve the patient's exposure to radiation, this study aimed to evaluate the diagnostic accuracy of ultrasonography for verifying gastric tube placement in newborns.<bold>Methods: </bold>This was a prospective, double-blind, observational study performed in a neonatal intensive care unit, in which 159 infants had gastric intubation using ultrasound examination and radiological imaging, to verify positioning. Results were analyzed in terms of diagnostic accuracy.<bold>Results: </bold>The tubes were correctly positioned in 157 cases (98.7%), according to radiological images, and in 156 cases (98.1%), according to ultrasound. The sensitivity analysis was 0.98 and the positive predictive value was 0.99. It was not possible to perform a specificity analysis, as there were not enough negative cases in the sample.<bold>Implications For Practice: </bold>The use of ultrasonography to identify correct positioning of gastric tubes in infants and newborns shows good sensitivity.<bold>Implications For Research: </bold>It was not possible to evaluate the ultrasonography specificity; further studies with greater samples are probably necessary, so that this objective can be achieved.Video Abstract available at https://journals.lww.com/advancesinneonatalcare/Pages/videogallery.aspx?videoId=29&autoPlay=true.
