Clinical Study of Placental Abruption / 日本農村医学会雑誌

ABSTRACT

　　Placental abruption occurs suddenly and may cause maternal and fetal mortality. Forced delivery is the only way to improve perinatal outcome, but the aftereffects could be severe despite a high survival rate.　　Our hospital manages approximately 170 cases of maternal transport annually, including cases of severe placental abruption. Longer transport time can lead to undesirable maternal and fetal outcome. Hence this study, we compared the perinatal backgrounds and outcome of placental abruption retrospectively between the cases managed by maternal transport and by the local hospital (our hospital). The study included 54 cases of placental abruption during the period from January 2008 to December 2012, of which 27 cases were managed by our hospital, the other halves were managed by maternal transport. There were 6 intrauterine fetal deaths but not a single maternal death. There were no significant differences in the amount of blood lost and obstetric DIC (disseminated intravascular coagulopathy) score between two groups (p＝0.342, p＝0.649), and the number of cases that needed anti-DIC therapy and blood transfusion in each group was statistically similar (p＝0.807, p＝0.115). The time taken from the on-set of placental abruption to delivery was significantly shorter for the cases managed by our hospital (in-hospital management 143±133 minutes, maternal transport management 265±176 minutes, p‹0.05), while obstetric DIC score and Apgar score showed no significant differences (p＝0.336, p＝0.780) between the two groups. Thus, it could be said there were no correlations between the time taken from onset to delivery and perinatal outcome. It should be noted, however, maternal and fetal outcome of placental abruption could be fatal even with the rapid intervention, so quick diagnosis and management at the first contact are crucial. Thus, we concluded that forced delivery managed by the local hospitals is necessary for the potential better perinatal outcome, and an ideal system to manage maternal and/or neonate transport after the delivery should be established immediately.
