| Research Abstract |
1) Coagulation studies were carried out in 65 newborn infants with non-traumatic intracranial hemorrhage. Based on the findings of coagulation status, it was estimated that 31 out of 65 neonates were suffered from DIC and/or primary hemorrhagic disease of the newborn. Mortality of the cases with coagualtion abnormalities was significantly higher than that of cases without coagulation abnormalities.
2) Next study was carried out in order to clarify the effects of gabexate mesilate(FOY) and antithrombin III concentrates on DIC of newborn infants. FOY was superior to heparin in improvement of clinical findings of DIC, although no difference was seen in changes of loboratory findings on hemostasis between the patient group treated with FOY alone and the other treatment groups. Those results indicated that the administration of FOY was more effective than haparin therapy for the DIC of newborn infants. Furthermore, a combination therapy of FOY and antithrombin III concentrates is effective for the DIC in newborn infants in whom administration of FOY alone was not effective.
3) We administered factor XIII concentrate to premature infants within 6 hours of age to examine its effectiveness in reducing the incidence of severe intracranial hemorrhage. Seven(29%) out of 24 control infants sustained intraventricular hemorrhage, and 3(13%) of 24 infants receiving the treatment did. Incidence of severe intraventricular hemorrhage in treated and control infants with high risk for intraventricular hemorrhage was 20% and 83% respectively. Factor XIII concentrate appears to have a beneficial effects on the prevention of intraventricular hemorrhage in premature infants.
