[Normal blood pressure values in neonates and physiologic factors in its variability].
Noninvasive examination of blood pressure by ultrasound sphygmomanometry (LUD 802-TESLA) carried out in 150 physiologic neonates provided insight into resting values of systolic and diastolic blood pressure and heart rate in this series of our urban population (mean value on postnatal day 2:64 +/- 10/36 +/- 7 Torr--8.5 +/- 1.3/5 +/- 0.9 kPa, HR 119 +/- 11. min-1). The paper quantifies the postnatal development of blood pressure over the first days of life, as well as the gradual differentiation of values in wakefulness and sleep and reactive changes at food intake, changes of posture, and at crying. Our original finding of circadian blood pressure variation already in the first postnatal days has been confirmed, with individual blood pressure chronograms exhibiting a predominance of the ultradian component.
