Abstract
Infants admitted to the Neonatal Intensive Care Unit have many risk factors that may predispose them to hypertension. To determine if infants with Bronchopulmonary Dysplasia (BPD) are at greater risk for hypertension, we evaluated blood-pressure (BP) in 114 infants with a birthweight < 2 kilograms. BPs were obtained in infants hospitalized for one month or longer either directly or by Doppler method if direct method was unavailable. BP was evaluated at one week and one month of age. The incidence of patent ductus arteriosus and presence and grade of intraventricular hemorrhage were examined. In addition, we analyzed the duration of umbilical artery placement. All data were analyzed by birthweight groups. There was significant increase (p < .01) in mean and systolic BPs from one week to one month in infants with BPD and < 1000 grams. At one month the infants < 1000 grams and with BPD had significantly higher BPs than those without BPD in the same weight group (p < .01). There was no correlation in these infants with the incidence of intraventricular hemorrhage or patent ductus arteriosus. The mean duration of umbilical artery catheter placement in infants < 1000 grams with BPD was 12 days compared to 3.8 days in those infants without BPD in the same weight group. The infants with BPD and < 1000 grams birthweight thus are at risk for hypertension.
