RESUMEN
BACKGROUND: Enteral feeding by a transpyloric tube in critically ill infants is indicated when there is a failure in gastric feeding. However, there is a wide variability regarding the insertion technique. PURPOSE: To perform a systematic review of the methods for inserting a transpyloric feeding tube in newborns and infants. DATA SOURCES: Nine databases, without date or language restrictions, accessed in September 2021. STUDY SELECTION: A systematic review of experimental and nonexperimental studies, according to the "Patient/problem; Intervention; Comparison; Outcome" strategy and the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" guidelines. The clinical question was about the measurement and insertion techniques, as well as the success rates of properly placing a transpyloric tube in newborns and infants. DATA EXTRACTION: Two authors (N.M.Q. and J.F.S.) analyzed 6 observational descriptive prospective studies, all of them published in peer-reviewed indexed medical journals and one in the official journal of the National Association of Neonatal Nurses. RESULTS: The success rate varied between 70% and 100%. There was an important variability in the type of tube, measurement method, and insertion techniques. It was found that the most common strategies to achieve proper positioning were glabella-calcaneal measurements, gastric air insufflation, and right lateral decubitus. IMPLICATIONS FOR PRACTICE: A transpyloric catheter insertion protocol needs to be established in each neonatal unit, according to the literature findings. IMPLICATIONS FOR RESEARCH: Randomized controlled studies that evaluate the gastric air insufflation technique and other adjuvant measures could elucidate the knowledge gap concerning the correct positioning of transpyloric tubing in newborns and infants.
