The hospital collected 110 cases of patients with different degrees of HDP who attended the hospital from September 2016 to December 2017 and were delivered in the hospital for inclusion in the study. According to the severity of hypertension, the above population was divided into the HDP group (59 Cases), mild preeclampsia group (28 cases), severe preeclampsia group (17 cases), eclampsia group (20 cases), observe the incidence of postpartum hemorrhage in each group.

In short, the incidence of postpartum hemorrhage in the severe preeclampsia group and the eclampsia group was significantly higher than that of the HDP group and mild preeclampsia; and the incidence of postpartum hemorrhage in the eclampsia group was also significantly higher than that of the severe preeclampsia group. The incidence of postpartum hemorrhage is positively correlated with the severity of HDP. As the severity of HDP increases, the incidence of postpartum hemorrhage also increases.

Therefore, for patients with HDP, active measures should be taken to prevent postpartum hemorrhage, strengthen health care during pregnancy, and correct anemia and proteinemia in time; maintain a balanced diet, supplement calcium ions and maintain a balance, avoid prolonged use of antispasmodic drugs, and pay attention to the fetus Intrauterine state; when the condition is severe, the patient should be communicated and the pregnancy should be terminated. With the increase in the severity of HDP, the incidence of postpartum hemorrhage has also further increased. Active measures should be taken to prevent postpartum hemorrhage, strengthen health care during pregnancy, and correct anemia and proteinemia in time. At the same time, we should take precautions before they happen, make intervention predictions for pregnant women in advance, and actively carry out pregnancy screening. A large number of studies have proved that the serum PlGF value has a high predictive value for pregnancy-induced hypertension.。
