To analysis the trend of maternal death time and explore the impact of the variety of death causes and birth place to maternal death time. According to the data provided by Beijing Maternal and Children Health Hospital, the 372 death cases of pregnant and lying-in women from 1995 to 2010, a retrospective study was performed to analyze the death causes, maternal death time and the influencing factors. The MMR declined from 27.9 per 100 000 live births from 1995 to 2000 to 14.8 per 100 000 live births from 2006 to 2010, with a decline of 46.9%. Among the maternal death within 24 hours of delivery, 79.7% (106/133) died of obstetric hemorrhage, hypertensive disorder complicating pregnancy and amniotic fluid embolism. It took up 47.8% (64/134) from 1995 to 2000, reduced to 37.5% (45/120) from 2006 to 2010. At the same time, the maternal mortality ratio within 24 hours reduced from 40.2%(54/134) to 28.3% (34/120), the variation of death time was consistent with the causes of maternal mortality (χ² = 59.109, P < 0.05). Indirect obstetric causes increased significantly from 2006 to 2010, 53.2% (33/62) of pregnant women with heart disease, cerebrovascular disease and pulmonary embolism died in prenatal or more than 120 hours postnatal. Among the maternal death delved in hospital, 29.0% (29/100) died within 24 hours, 52 cases delved at home or in private clinics, 43 cases (82.6%) died within 24 h postnatal. There were significant differences between birth place and death time (χ² = 24.500, P < 0.05). Maternal death time changed from 24 hours of delivery to prenatal or postnatal a long time. The maternal mortality causes and hospital delivery is an important factor affecting maternal time.
