Are Venous Circulatory Abnormalities Important in the Pathogenesis of Hemorrhagic and/or Ischemic Cerebral Injury?

摘要: The venous circulatory changes in 12 intubated premature infants with fluctuations or elevations arterial BP were studied. objectives of the study to determine whether important alterations pressure occur associated suctioning. Venous and catheters present all infants. Perfusion was derived from difference between mean pressure. At rest, minimal change BP, pressure, perfusion observed. Elevations accompanied by pronounced However, because magnitude direction not consistent, resulted. Fluctuations which also resulted continuous Induced muscle paralysis two obliterated These data demonstrate that marked accompany common abnormalities; such on side circulation may be pathogenesis neonatal hemorrhagic and/or ischemic injury.
