Abstract：Objective To analyze the application effect of autologous blood continuous transfusion machine in caesarean section for patients with dangerous placenta previa. Methods A retrospective analysis was made on 120 cases of dangerous placenta previa diagnosed in the First Affiliated Hospital of Xinjiang Medical University from July 2016 to August 2018. They were divided into group A (n = 60) and group B (n = 60) according to whether autologous blood continuous transfusion machine was used during operation. Sixty patients in group A used autologous blood continuous transfusion machine during operation, while 60 patients in group B did not use autologous blood continuous transfusion machine. The intraoperative bleeding volume, blood transfusion and the changes of blood test indexes were compared between the two groups. Results There was no difference in intraoperative bleeding volume between the two groups (P > 0.05), The volume and rate of intraoperative transfusion of allogeneic blood products in group A were lower than those in group B (P < 0.05), and the preoperative preparation time in group A was lower than that in group B (P < 0.05). The levels of blood platelets (PLT), hemoglobin (Hb), and hematocrit (HCT) in the two groups were significantly lower than those before operation (P < 0.05), but there was no difference between the two groups (P > 0.05). Conclusion Continuous autologous blood transfusion machine can effectively reduce the amount and ratio of blood products transfusion, maintain circulating blood volume and save blood resources in the caesarean section in patients with dangerous placenta previa.
