[The effectiveness of using semipermeable membrane in preterm infants to reduce transepidermal losses]. / Eficácia do uso de membrana semipermeável em neonatos pré-termo na redução de perdas transepidérmicas.

ABSTRACT

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.
