Objective To analyze the effect of different modes of autologous blood reinfusion on coagulation function of fetus and dangerous placenta previa pregnant woman undergoing cesarean section.
Methods Ninety pregnant women with dangerous placenta previa were divided into dilution group (n=45) and blood recycle group (n=45). Blood compositionplatelet count (PLT), erythrocyte hematocrit (Hct), hemoglobin (Hb), blood coagulation function indexesprothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), hemodynamic indicators (heart rate, mean arterial pressure, blood oxygen saturation) of pregnant women before and after treatment, neonatal 1 min and 5min Apgar scores and adverse reactions of two groups were compared.
Results The 1 min and 5 min Apgar scores in the blood recyclegroup were (9.23±0.53) and (9.87±0.61), respectively, and (9.31±0.57) and (9.89±0.60) respectively, in the dilution group, but no differences were found in two groups (t=0.379, 0.673, P=0.681, 0.482). The incidence of adverse reactions in the blood recycle group was significantly lower than that in the dilution group (4.44% versus 22.22%, P < 0.05).
Conclusion Both hemodilutional autologous transfusion and intraoperative autotransfusion have little influence on blood composition, coagulation function, hemodynamics of pregnant women and fetal physiological activities. However, intraoperative autotransfusion mode is more flexible in use and has fewer adverse reactions.
