    ABSTRACT: Serial electrocardiograms (ECGs) were studied prospectively in 80 apparently healthy newborn infants; 30 infants exposed in utero to prolonged tocolytic therapy (21 to ritodrine and 9 to isoxsuprine) and 50 infants non-exposed in utero to drugs (control group) matched for gestational age, Apgar score, and birth weight. Duration of exposure to tocolysis was at least 30 days (30-180 days) with an oral dosage of 10 mg 3 times daily. ECGs were graded for changes suggestive of ischaemia using the arbitrary grading system described by Jedeikin et al. In all infants with ECG features of myocardial ischaemia, serum creatine-phosphokinase iso-enzyme (CK-MB) activity was measured. Six out of 21 infants to ritodrine and six out of nine infants exposed to isoxsuprine showed a degree of ECG ischaemia which persisted for several weeks. No control infant presented grade 2 or 3 ECG changes after the 5th day of life. The results of this study seem to show that prolonged tocolytic therapy with beta-sympathomimetics has side-effects on the fetal myocardium and suggest that this treatment be reserved only for selective cases and/or for short periods of time.

    ABSTRACT: A fully automatic noninvasive device (Dinamap) was used for monitoring blood pressure (BP) and heart rate repetitively over 48 h in 21 full-term newborn infants (9 males and 12 females), aged 4 days in order to clarify the occurrence of a circadian rhythm (CR). The data collected were analyzed by computer statistical analysis. Mean values and standard error of BP and heart rate measured at hourly intervals in males and females were computed and plotted as chronograms. However, each newborn infant was analyzed for a CR of BP and heart rate by the single cosinor fit of a 24-hour cosine curve. The analysis of the chronograms revealed that the values of systolic and diastolic BP show an hour-by-hour significant fluctuation in male infants, but not in female infants. CR development of BP is present only in a minority of newborn infants and reveals sex and interindividual differences. CR of heart rate is absent in all infants. The physiological significance of these findings was discussed, and the importance of knowing the physiological variances of BP in infants in order to obtain a correct clinical evaluation was stressed.
