A prospective study on the accuracy of two methods to confirm the positioning of the nasogastric tube

Abstract

The objective of this study is to analyze the accuracy and limitations of the combined method (auscultation and pH measurement) and ultrasonography to confirm the positioning of the nasogastric tube (NG) in hospitalized adult patients. It is an observational, prospective study of the evaluation of different diagnostic methods. Data will be collected in the clinical and surgical wards of a university hospital, in São Paulo state. The sample will consist of all patients who agree to participate in this study during the period of data collection that will correspond to 13 (thirteen) months. The study will be operationalized in four steps: (1st) integrative review of the literature, (2nd) elaboration and refinement of the data collection form, (3rd) pilot study, and (4th) data collect. The combined method and the ultrasound method will be performed in all participants of the study, for future comparison with the X-ray examination, considered the gold standard in the confirmation of the NG position. Socio-demographic, clinical and therapeutic data will be obtained from medical records and will be recorded in the data collection form, which one was developed for this study. The direct costs of each method used to confirm NG placement will be measured and the impact of each method on the average direct cost of the patient will be evaluated. The expectation is that the results of this study demonstrate the availability and safety of two methods used in the placement confirmation of blindly NG, inserted at the bedside. Also, it is expected that such methods will present lower costs when compared to radiography, which is considered gold standard in the placement confirmation of enteral tubes. (AU)
