Research Abstract

We assessed the hypothesis that serum hypoosmolality promoted closure of the ductus arteriosus (DA). We showed both from human clinical observations and rat experiments that serum hypoosmolality augmented DA closure. The results suggest the importance of maintaining the serum osmolality in a proper levelfor early preterm infants early after birth.
