Abstract:
【Objective】 To explore the corresponding strategies of blood preparation for placenta previa operation in our hospital according to the situation of blood transfusion during and after operation. 【Methods】 Ninety pregnant women with placenta previa (complete, partial or marginal) undergoing the caesarean operation and blood transfusion in our hospital from January 2011 to September 2020 were selected as the research objects. The corresponding data about intraoperative/postoperative blood loss, blood transfusion and blood preparation were collected, analyzed and compared. 【Results】 There was no significant differences in age between complete and marginal placenta previa(P>0.05), but significant differences in intraoperative/postoperative blood loss and the units of blood transfusion (P<0.05). The blood loss of marginal placenta previa was less (≤1 000 mL) and the units of blood transfusion were mainly 3 (2, 3) U. Complete placenta previa was more likely to cause serious postpartum bleeding (>1 000 mL). The difference between ordering and transfusion units of complete and marginal placenta previa were 0.4 and 0, respectively. When the complete placenta previa was accompanied by placenta increta or placenta percreta, the blood loss was larger (>1 000 mL) and the units of blood transfusion ranged from 4.5 U to 6 U, while the blood loss was generally low (≤1 000 mL) and the units of blood transfusion was concentrated at 3 (2, 4) U without placenta accreta nor implantation.The difference between ordering and transfusion units of complete placenta previa with non-implantation, placenta accreta, placenta increta and placenta percreta were 0.165, 0.33, 0.5 and 1, respectively. 【Conclusion】 For marginal placenta previa, 3U blood is recommended for routine preparation, 3U blood for complete placenta previa with non-implantation or placenta accrete, and 4.5-6U for complete placenta previa with placenta increta or placenta percreta.
