Acute impact of posthemorrhagic ventricular dilatation on cerebral oxygenation in preterm infants with intraventricular haemorrhage.

and lower cFTOE levels during the study period. In these patients, ventricular decompression did not further affect cerebral oxygenation, as they already demonstrated improved cerebral hemodynamics, whereas an immediate improvement was observed in those without prior lumbar punctures.
