[Hydrocephaly in newborns with perinatal brain damage of moderate severity.]
A prospective examination of 103 newborns with hypoxic damage of the central nervous system of moderate severity was conducted on the 4-7, 10-14 and 21-28 days after birth and included clinical examination, neurosonographic study with dopplerography of great brain arteries and biochemical study of venous blood and urine. Children with ventriculomegalia were treated with diacarb. A control group included 15 newborns without signs of survived hypoxia. Ventriculomegalia was found in 29% of children in the main group and remained till the end of neonatal period in 15%, with moderate and large dilatation in 63,5% and mild dilatation of anterior horns of lateral ventriculars in 36,5%. The markers of development and long remaining ventriculomegalia are specified as follows: the morphofunctional immaturity of the brain (RR=1,7; 95%CI 1,16-2,45), absence of compensatory reduction of resistance index (RI) in anterior brain arteries on 4-7 days of life (RR=3,03; 95%CI 2,11-4,31), metabolic acidosis – the bicarbonate level in the venous blood less than 21 mmol/l (RR=2,9; 95% CI 1,66-5,02), carbanhydrase activation – bicarbonate concentration in the urine less than 5 mmol/mcmol of creatinine on 4-7 days of life (RR=3,81; 95%CI 2,87-5,02). Diacarb in ventriculomegalia should be prescribed only in case of disturbance of the organism compensatory reaction because it causes the significant increase of compensatory reduced RI. The drug has a nephrotoxic effect and causes metabolic acidosis.
