[Duplex Doppler echography as a non-invasive method of evaluating cerebral blood flux, in full-term newborns, in the immediate neonatal period].
The Doppler effect and its application on the human body is described as well as its specific use in pediatric age: cerebral blood flow, liver and renal transplants, vascular-renal and portal hypertension and characterization of mass, tissue and structure. The results of 107 studies with Doppler duplex echograph on 86 neonates are analysed. The anterior and posterior cerebral arteries were sounded. The parameters taken into consideration were ten maximum systolic velocity (VS), the final diastolic velocity (VD), Bada's pulsatility index (IP) and the morphology of the curve. In 35 normal newborns the results were: maximum systolic velocity 24.08 +/- 4.30 cm/s, the final diastolic velocity 8.77 +/- 1.86 cm/s, Bada's pulsatility index. In the caesarean born neonates in both forms of anaesthesia, and those born by EVA delivery (stimulation, suction and analgesia) slight increases were observed, in comparison with the normal newborn group, in the maximum systolic velocity and Bada's pulsatility index.
