Abstract
The circadian amplitude of neonatal blood pressure, monitored for 2 days at 30-minute intervals during the first week of life on 39 babies exposed in utero to betamimetics, was statistically significantly larger than that of the 126 unexposed babies. The respective circadian double amplitudes (± SEM) were 7.9 ± 0.8 vs. 5.6 ± 0.3 mm Hg for systolic blood pressure (P=0.005) and 5.7 ± 0.6 vs. 4.0 ± 0.2 mm Hg for diastolic blood pressure (P = 0.020). An above-threshold circadian amplitude of blood pressure being associated with an increased cardiovascular disease risk, the results, corroborated independently during adolescence, warrant caution in prescribing betamimetics to prevent premature labor.
