Análisis del concepto de sondaje orogástrico en neonatos prematuros, según el método evolutivo / Concept analisys orogastric tube in premature neonates according to the evolucionary method

OBJETIVO: analizar el concepto de sondaje orogástrico en neonatos prematuros en las publicaciones científicas, con base en el método evolucionario. METODOLOGÍA: se trata de un estudio de análisis del concepto fundamentado en las etapas del Método Evolucionario, donde lo más destacado es la investigación inductiva y descriptiva, con énfasis en la naturaleza del concepto, que se construyó a partir de una revisión de literatura realizada en las bases de datos CINHAL, Medline/PubMed, Lilacs, BDENF y Scielo, con los términos "orogastric tube" OR "oral gastric tube" AND "Infant, Premature". RESULTADOS: Se organizó la síntesis del análisis del concepto, en la cual constan los atributos esenciales y los términos sustitutos que a menudo están asociados al concepto de sonda orogástrica, en los más distintos contextos y áreas. Además, se señalaron los eventos anteriores prevalentes para expresar la ocurrencia del concepto analizado y los eventos consecuentes que se manifiestan como resultado del uso del concepto. CONCLUSIÓN: el método utilizado permitió identificar, organizar y aplicar el concepto del estudio, de forma a explorar el significado atribuido al concepto de sondaje orogástrico en neonatos prematuros.

OBJECTIVE: to analyze the concept of orogastric tube in premature neonates in scientific publications based on evolutionary method. METHOD: It is a concept analysis study based on the steps of Evolutionary Method, in which the highlight is the inductive and descriptive research, with emphasis on the concept of nature, which was built from a literature review conductedin the following databases: CINAHL Complete, Medline / PubMed®, LILACS, BDENF and Scielo using the terms "orogastric tube" OR "oral gastric tube" AND "Infant, Premature". RESULTS: From the reading of this material found was organized synthesis of concept analysis, bearing the essential attributes and terms substitutes that are often associated with the concept orogastric tube, in various contexts and areas. In addition, they indicated is the prevailing background events to express the concept occurring in question and the events consequential occur as a result of the use of the concept. CONCLUSION: the method used allowed to identify, organize and apply the study concept, in order to explore the meaning attributed to the concept of orogastric probing in preterm infants.

Effects of Orogastric Tubes on the Videofluoroscopic Swallowing Study Findings in Infants / 대한연하장애학회지

OBJECTIVE: An orogastric tube is used frequently in infants because infants are obligate nose breathers and nasogastric tubes can cause partial nasal obstruction. This study examined whether the presence of an orogastric tube could affect the swallowing parameters assessed by a videofluoroscopic swallowing study in infants with dysphagia caused by a variety of reasons. METHODS: Tests were conducted in 15 infants aged less than 150 days after birth who used an orogastric tube due to dysphagia. Two tests were conducted. The first was conducted with an orogastric tube inserted. Subsequently, the orogastric tube was removed with a 5-minute break before the second test. Skilled physiatrists then analyzed the recorded video. The number of sucks required for one swallow, abnormalities of the pharyngeal phase, and penetration-aspiration scales were evaluated. RESULTS: After removing the orogastric tube, the number of sucks required for one swallow reduced significantly (2.50±1.73 vs. 3.45±2.54, P=0.04). On the other hand, no statistical significance was observed in the results of the pharyngeal phase and penetration-aspiration scale (5.60±3.16 vs. 5.9±3.81, P=0.41) with and without the orogastric tube. CONCLUSION: These findings showed that the insertion or non-insertion of an orogastric tube might not affect the swallowing abnormalities in the pharyngeal phase and the risk of aspiration. In addition, an orogastric tube may have a negative effect on the swallowing function in the oral phase.
