Abstract

We studied 45 very low birth weight infants for change in birth weight, urine output, serum Na level, ventilatory support and outcome between two groups after fluid restriction therapy. Group 1 (n=17) were infants whose weight loss were more than 5% of birth weight. Group 2 (n=17) were infants whose weight loss were more than 5% of birth weight. 1) Group 1 had more fluid intake and less urine output than group 2. 2) Urine specific gravity and serum Na level were within physiologic ranges in both groups. 3) Group 1 needed more ventilatory assistance than group 2. 4) Group 1 had more complications and higher death rate than group 2. PDA occurred more frequently in group 1. We concluded that greater initial weight loss in very low birth weight infants after fluid restriction can reduce the complications, especially PDA, and ventilatory support.
