[Noninvasive blood pressure determination in newborn infants].

In 69 newborns (birth weight 900-3820 grams; gestational age 27-41 weeks) the Dinamap device was used to establish normative values for systolic and diastolic blood pressure, mean arterial pressure and pulse pressure for this indirect, non-invasive blood pressure monitoring system. Reference values for the first day after delivery in different birth weight groups are given and the changes during the first three days of life are shown. Blood pressure variability as a possible additional parameter in neonatal monitoring was found to be independent of birth weight and gestational age.
