| Research Abstract |
As is already well known, intracranial bleeding at perinatal period is one of the highest mortality in newborninfant. In addition there are many those cases in asphyxiated newborns.
In order to clalify these pathological fibrinolytic systems and platelet metabolism, following studies were tried.
50 cases of cordvenous blood were tested.
(Methods) i) Bloodcoagulation-Fibrinolytic system.1)Fibrinogen,2)FDP,3)SFMC.
ii) platelet-Aggregation.
iii) plateletvolume.
(Results)
Characteristic features of asphyxiated newborn infants are as follows.
i)Increasing of SFMC. 4.8 <plus-minus> 1.6 % (normal 3.1 <plus-minus> 0FMC.
ii)Low values of platelet-Aggregation. 8.2 <plus-minus> 1.7 (<OMEGA>) (normal infants. 11.6 <plus-minus> 2.4)
(Collagen.)
iii)High values of plateletvolume. 8.6 <plus-minus> 1.4 c.u. (normal 7.5 <plus-minus> 1.3 c <pl
(Concluion.)
These features indicate that asphyxiated newborn shows hypercoagulability and slow circulation, and it could be the reason of Disseminated Intravascular Coagulation.(DIC.)
