Introduction: the insertion of the gastric tube in neonatology is a widely used procedure, but it presents risks according to its different techniques.
Objective: to explore current literature regarding the best measurement methods and techniques for checking gastric tube insertion in neonates.
Methods: scoping review of literature in PubMed, ScienceDirect, LILACS and GoogleScholar databases, using "neonate, gastric tube and placement" and their acronyms as descriptors, in original articles, between 2009 and 2023.
Results and Discussion: 17 articles were included, classifying them into "measuring methods" or "verification techniques" *. Measurement methods found were: tip of the nose-earlobe-xiphoid process (NEX), tip of the nose-earlobe-midpoint between xiphoid process and umbilical scar (NEMU), weight-based formula, height-based formula and modified NEX. NEX was deprecated. Checking techniques, discarding the gold-standard, were: wheezing auscultation, gastric content aspiration, ultrasound, pH and indigo-carmine, with ultrasound and pH being more reliable.
Conclusion: results showed that NEMU and the weight-based formula are superior as a measurement method. In verification techniques, ultrasound and pH stand out. There is a lack of protocols and regulations for this procedure.
