Correlation of Component Blood Transfusion of Hypertension Patients with Pregnancy and Postpartum Hemorrhage by Ying Li, Jinjing Wang, Kai Wang, Tao Peng, Hongyan Liu, Hong Zheng, Qiong Hu

Background: To analyze the correlation of component blood transfusion and prognosis of patients with pregnancy-induced hypertension (PIH) and postpartum hemorrhage (PPH) in assisted reproductive technology (ART). Methods: A retrospective analysis of clinical data on 85 pregnant women with ART-induced PIH and PPH was completed. They were divided into observation group and control group based on whether there was component transfusion after massive hemorrhage. The plasma coagulation and blood platelet-related indexes of the two groups of patients were assayed before blood transfusion, 24 hours after blood transfusion, and 12 weeks post-partum. The incidence of adverse reactions of blood transfusion within one week of blood transfusion, the proportion of patients transferred to the general ward, the blood pressure, and biochemical indexes at 12 weeks postpartum were recorded.
Results: There was no significant difference in coagulation function before blood transfusion between the two groups of patients (p > 0.05). After 24 hours of massive blood transfusion, APTT, PT, and TT in the observation group were obviously shorter than those in the control group (p < 0.001), whereas FIB and PLT were higher than the control group (p < 0.01). In contrast to the control group at 12 weeks postpartum, the APTT, TT, and PT of the observation group were shortened (p < 0.05), while the FIB level was higher (p < 0.01). The probability of adverse reactions of transfusion in the observation group was lower than the control group (p < 0.05). The correlation between component transfusion and disease improvement after one week of transfusion and 12 weeks postpartum was 0.350 (0.159 - 0.530) (p < 0.01) and 0.441 (0.258 - 0.608) (p < 0.001).
Conclusions: Component blood transfusion in ART-induced PIH patients can improve their coagulation function, reduce the probability of adverse reactions caused by massive blood transfusion, and improve their prognosis.
