Direct arterial blood pressure was measured in 128 infants admitted to a neonatal intensive care unit. Birth weight and gestational age were the most significant factors influencing initial blood pressure. A significant reduction in mortality occurred in infants with initial blood pressures less than 40 cm H2O whose blood volume was expanded with albumin or whole blood. Further studies are needed to better identify those high risk infants whose prognosis may be improved by the use of volume expanders.
