Clinical significance of adverse outcomes of placental abruption developing at home.

We reviewed the obstetric records of 40 singleton deliveries complicated by placental abruption which developed at patients' homes after 24 weeks' gestation. Of the 40 cases complicated by placental abruption which developed at home, 13 cases (33%) were defined as showing adverse outcomes (5 cases of IUFD and 8 cases of UA pH < 7.0). The rate of patients who complained of abdominal pain without bleeding was higher in the adverse outcome group than in the control group (p = 0.02). The average time interval between the onset and hospital (or clinic) visit in the adverse outcome group was longer than in the control group (p = 0.03). Adverse outcomes due to placental abruption which developed at home were associated with the symptom of pain without bleeding and a long time interval between the onset and hospital (or clinic) visit.
