Vasoactivity of the major intracranial arteries in newborn infants.

Vasoactivity of the major intracranial arteries in newborn infants.

Blood flow to the head and arms was measured by a new volumetric Doppler technique in 30 preterm infants and 10 full term infants. At least 80% of this blood flow is considered to perfuse the brain. At the same time mean blood velocity in the middle and anterior cerebral arteries was measured by Duplex Doppler scanning. While blood flow to the head and arms remained substantially constant in bo...

Intracranial Serratia infection in preterm newborn infants.

Four cases of cerebral Serratia infection in preterm infants were diagnosed with the aid of real-time sector sonography. Three cases had brain abscesses and one case had ventriculitis. In two cases brain abscesses had ruptured into the ventricles. Serratia brain abscess was common in our series of brain abscesses. Sonographic patterns of cerebritis, abscess formation, and ventriculitis correlat...

Vasoactivity of intraluminal and extraluminal agonists in perfused retinal arteries.

PURPOSE To evaluate the vasoactive response of isolated perfused arteries of the pig to K+ and adrenergic agonists and to compare the effects of intraluminal (IL) and extraluminal (EL) drug delivery. METHODS A new microperfusion system was developed, in which short lengths of porcine retinal arteries (outer diameter 90.4 +/- 2.7 microns) were cannulated at both ends and perfused at a controll...
