Abstract
Objective To explore the trend of postpartum hemorrhage after two-child policy and to analyze the high-risk risks of postpartum hemorrhage so as to put forward intervention measures to reduce the postpartum hemorrhage. Methods We retrospectively selected 8 784 delivery women with routine production inspection and hospitalized at a ClassⅢ Grade A hospital from 2014 to 2018. We collected the general information, record of production inspection, delivery record and analyzed the trend of postpartum hemorrhage rate, blood loss and related high-risk factors. Results From 2014 to 2018, there were statistical differences in the postpartum hemorrhage rate, serious postpartum hemorrhage rate and blood loss (P<0.05) . The trend showed an increasing trend. In 2017, the postpartum hemorrhage rate, serious postpartum hemorrhage rate and blood loss were 16.9%, 6.1% and (540.1±758.2) ml respectively highest in those years. From 2014 to 2018, the percentage of delivery women with advanced ages, multiple pregnancy, pregnancy times≥2, history of cesarean section≥2 were increasing; delivery women with the prenatal hemoglobin≤110 g/L and percentage of natural labor were decreasing with a statistical difference (P<0.05) ; the percentage of emergency cesarean section was on the rise; the percentage of placental expulsion time from 15 to 30 minutes declined with statistical differences (P<0.05) ; the percentage of placental expulsion time≥30 minutes and above was no significant trend. Conclusions From 2014 to 2018, the postpartum hemorrhage rate, serious postpartum hemorrhage rate and blood loss did not show an increasing trend. However, the percentage of high-risk pregnant and delivery women increased gradually. Therefore, we should carry out the pregnancy risk assessment rating for pregnant and delivery women and formulate a suitable high-risk assessment tool for postpartum hemorrhage so as to reduce the incidence of postpartum hemorrhage.
