Parameters circulation in arteria cerebri anterior at newborns with perinatal pathology

Abstract

With the purpose of definition of parameters cerebral circulation (CC) we used transcranial ultrasonic dopplerometria artery cerebra anterior (АСА) at 40 term infants in the age of 1-6 day (the scanner Aloka- 650, transducer 5 MHz) at children with the complicated current of the perinatal period (basic group - 32 children with neurology diseases, hypotrophia, infants of diabetic mothers) and control group (8 healthy newborns).

Maximal value of systolic cerebral blood flow velocity in АСА at all newborn control group changed from 25,6 up to 51 cm/s, in too time at 22 (71%) children of the basic group it was lower 25,6 cm/s (P < 0,001), and here have come 8 of 10 children of diabetic mothers. Minimal value of diastolic cerebral blood flow velocity in АСА also was authentically above at newborn control group (8,1 - 14,0 cm/s). The systolic-diastolic ratio (S/D). index of resistance (Rl) at children of the basic group had the greater disorder of meanings (in the control an index S/D has made 2.71 - 3.92, Rl - 0.63 - 0,74). At newborn with Rl > 0.75, it was marked more expressed neurology diseases with prevalence of an oppression of cerebral function, than at children with Rl < 0,75.
