The Value Assessment Of MCA Blood Flow Parameters On The Intracranial Hemorrhage In Premature Infants

Objective Explore the intracranial hemorrhage, premature craniocerebral dopplerultrasonography (TCD) check the middle cerebral artery (MCA) of cerebral blood flowvelocity (CBFV) compared with normal preterm infants, the change rule of differentdegree of intracranial hemorrhage, premature TCD examination MCA different changes ofthe blood flow parameters, discusses different gestational age, birth weight, influence onpreterm infant intracranial hemorrhage (ICH), for intracranial hemorrhage in the prematureinfant early prediction, diagnosis and treatment to provide new ideas and targets.Methods In March2013to January2014in our hospital pediatric hospital treatment andnew born February all conform to experiment the inclusion criteria and sign agreement of65cases were premature application of CT examination clear symptomatic intracranialbleeding, according to the premature symptomatic intracranial hemorrhage were dividedinto group of29cases of intracerebral haemorrhage, no intracranial hemorrhage group,control group36cases, at the same time, record its clinical manifestations. And applicationof craniocerebral doppler flow imaging (cdfi) in the postnatal day age1,3and7day ageage check MCA blood flow parameters. The inclusion criteria for amniotic fluid, and thereis no history of asphyxia rescue, unincorporated severe congenital disease, birth defectsand agreed to participate in the experiment of premature infant and their families. MCAblood flow parameters of each child records, including systolic peak flow velocity (Vs),diastolic peak flow velocity (Vd), resistance index (RI), pulse index (PI) in the blood flowparameters, such as application value in evaluation of intracranial hemorrhage in thepremature infant, and discuss the analysis of intracerebral hemorrhage group with MCA Vs,Vd, RI, PI the dynamic change of the blood flow parameters, such as was the associatedwith the incidence of intracerebral haemorrhage.Results Intracranial hemorrhage group premature Vs, Vd faster than control group inpremature infants, statistically significant differences (P <0.05);②of intracranial hemorrhage, Vs, Vd, the more obvious increase fast, however the more severe intracranialhemorrhage, RI, the lower the value of PI, statistically significant difference (P <premature gestational age0.05);③Is smaller, the more prone to intracranial hemorrhage,statistically significant differences (2=6.133, P <0.05);④premature infant birth weightis lower, the more prone to intracranial hemorrhage, differences are statistically significant(2=10.181, P <10.181).Conclusion Premature high incidence of intracerebral haemorrhage, of which the smallergestational age, birth weight, the lower the higher the risk of premature, so all prematureconventional cerebral doppler ultrasound. Premature infants with intracranial hemorrhageabnormal changes of the cerebral blood flow, application of TCD examination can befound that MCA blood flow parameters are changed, intracranial hemorrhage in prematureinfants MCA Vs, Vd, RI, PI is the blood flow parameters, such as intracranial hemorrhagein premature infants, its change has a certain regularity and to a certain extent, haspredictive value to the cases, and TCD have timely, noninvasive and accurate, therepeatability of higher advantage, has the important practical value in the clinical work,worthy of further promotion.
