Participants 72 preschool children at risk of poor development due to maternal placental insufficiency (documented with an abnormal umbilical artery Doppler velocity waveform). Mean age 4 years (range 2–5 years); 53% female. Exclusion criteria were gestational age under 29 weeks at birth; families that did not speak French at home; location outside metropolitan area; chromosome disorders; conge...

Arterial compliance (C) has been measured in 18 children known to have had a single umbilical artery at birth. Non-invasive ultrasonic Doppler techniques were used to measure C for the aorta, iliac, and leg arteries. Anomalous compliance was found between the two iliac vessels, and it is suggested that this is the result of haemodynamic stress-induced changes during development. The demonstrati...

Background: The mainstay of care for lowering maternal and perinatal mortality morbidity is antepartum foetal surveillance. Numerous techniques are used, including fetal movements, Vibroacoustic stimulation tests, contraction stress biophysical profiles the fetus, modified profiles, non-stress testing Doppler Umbilical artery fetus's. heart reaction to internal extrinsic stimuli seen on electro...

A computer linked Doppler system was used to make continuous measurements of cerebral blood flow velocity (CBFV) from the middle cerebral artery, mean arterial blood pressure (MAP) from the umbilical artery, and heart rate before, during, and for 20 minutes after the endotracheal administration of 200 mg/kg of porcine surfactant in 10 preterm infants with respiratory distress syndrome. Within t...
