Objective:to examine changes in arterial blood pressure (abp) after birth in extremely preterm infants.study design:prospective observational study of infants 230/7 to 266/7 weeks gestational age (ga). antihypotensive therapy use and abp measurements were recorded for the first 24 h.result:a cohort of 367 infants had 18 709 abp measurements recorded. abp decreased for the first 3 h, reached a nadir at 4 to 5 h and then increased at an average rate of 0.2 mm hg h−1. the rise in abp from hour 4 to 24 was similar for untreated infants (n=164) and infants given any antihypotensive therapy (n=203), a fluid bolus (n=135) or dopamine (n=92). ga-specific trends were similar. abp tended to be lower as ga decreased, but varied widely at each ga.conclusion:abp increased spontaneously over the first 24 postnatal hours for extremely preterm infants. the rate of rise in abp did not change with antihypotensive therapy.
