Abstract:Objective To explore the intervention measures, complications and blood transfusion in the puerpera with different amount of postpartum hemorrhage (PPH). Methods A retrospective analysis was performed on the clinical data of 280 women with postpartum hemorrhage who gave birth at the First Hospital of Shanxi Medical University from June 2018 to May 2021.According to the amount of bleeding, the patients were divided into 1 000-2 000 ml group(n=213), 2 000-＜3 000 ml group(n=32) and ≥3 000 ml group(n=35). The intervention measures, complications during and postpartum and blood transfusion the intervention measures, complications and blood transfusion were observed and compared among the three groups. Results There were statistical differences in gestational weeks, times of pregnancy and delivery, scarred uterus, placenta previa, placenta accreta, dangerous placenta accreta, cesarean section rate and the incidence of transfer to ICU among three groups (P<0.01, P<0.05). There were statistical differences in the intervention measures of uterine compression suture（31.5%，62.5%，60.0%）, uterine artery ligation （0.5%，9.4%，20.0%）, pelvic vascular embolization （2.8%，9.4%，11.4%）, total hysterectomy and subtotal hysterectomy (P<0.01, P<0.05). There were significant differences in the incidences of disseminated intravascular coagulation (DIC) （0，6.3%，20.0%）, hemorrhagic shock （0.5％，3.1%，34.3%） and lung injury （0，6.3%，2.9%） among three groups(P<0.05). With the increase of bleeding volume, the infusion of red blood cells and fresh frozen plasma increased in 246 patients who received infusion therapy of blood product among three groups (H=126.228, 35.598, P<0.01). Conclusion The early warning grading of postpartum hemorrhage is helpful to take targeted drug, surgical intervention measures and reasonable blood component infusion so as to improve the maternal outcomes of PPH.
