ABSTRACT
Studies have shown that the application of semipermeable membranes to the skin of premature newborns (NBs) can aid in protecting the skin, reduce disturbances in fluid and electrolyte levels, and decrease neonatal mortality. The aim of this study was to verify the effect of using semipermeable membranes in low-birth-weight preterm newborns (PTNBs). A randomized controlled trial was carried out in the neonatal intensive care unit (NICU) with 42 NBs split evenly into an intervention group (IG), in which semipermeable membranes were used to cover large areas of the skin for the first 7 days of life, and a control group (CG), which received normal care. The variables investigated for the study were weight, hydration status, urinary density, glycemic control, sodium concentration, and daily hydration quota. The following variables displayed significant daily variation: weight, hydration quota, and sodium concentration. Statistically significant individual effects by day and by group were found only for sodium concentration. In the overall analysis of the intersubject effects, sodium concentration, alone, proved to be significant (p = .055). Significant effects by group in relation to the sodium concentration were found, with the IG showing a lower average sodium concentration than the CG. Thus, the use of semipermeable membranes reduced fluid loss in premature NBs in the current study, confirming the findings of previous studies. Guidelines for practice may now be warranted.

An investigation was made on the effectiveness of using semipermeable membrane on the skin of preterm infants on the evolution of weight loss and blood glucose values, water share, urine specific gravity and sodium. This is an experimental study, of the randomized clinical trial type, carried out from March to August 2008 in the Neonatal Intensive Care Unit of the Teaching Maternity Assis Chateaubriand (TMAC) in the city of Fortaleza-Ceará. The sample consisted of 42 preterm infants. The data were presented in tables and charts. In the application of the semipermeable membrane, the preterm infants of the intervention group (IG) had a decrease in the sodium levels and the daily flow demands, they also presented fewer hyperglycemia episodes and the urinary density was kept within normal patterns. The semipermeable membrane is, in fact, an effective therapeutic resource to minimize transepidermal water losses.

Neste estudo, investigou-se a eficácia do uso da membrana semipermeável na pele de recém-nascido pré-termo sobre a evolução da perda ponderal e valores da glicemia, cota hídrica, densidade urinária e sódio. Estudo experimental, tipo ensaio clínico randomizado, realizado no período de março a agosto de 2008, na Unidade de Terapia Intensiva Neonatal, de uma maternidade pública, na cidade de Fortaleza-Ceará, Brasil. A amostra foi constituída de 42 recém-nascidos pré-termo. Os dados foram apresentados em tabelas e quadros. Na aplicação da membrana semipermeável, os recém-nascidos pré-termos do Grupo de Intervenção tiveram uma diminuição de níveis de sódio e de exigências fluidas diárias, como também apresentaram menores episódios de hiperglicemia e a densidade urinária foi mantida dentro dos padrões de normalidade. A membrana semipermeável é, de fato, um recurso terapêutico eficaz para minimizar as perdas de água transepidérmicas.
