Objective

To investigate the change tendency of platelet(PLT) count in healthy pregnant women, and study the correlation between platelet count and postpartum hemorrhage, and perinatal outcomes.

Methods

From July 2006 to June 2007, the clinical data of 2 655 healthy pregnant women who delivered in the West China Second University Hospital, Sichuan University were investigated retrospectively.

Results

① The reference value of platelet count >80×109/L for the healthy pregnant women. The platelet count decreased during normal pregnancy. ② The incidence of gestational thrombocytopenia (GT) of healthy pregnant women before delivering was 22.29%. ③ There were no significant correlation between platelet count and the gravidity, parity, age, and occupation (P>0.05). ④ There were no significant difference between groups compared with volume of bleeding during caesarean section and vaginal delivery(P>0.05). Platelet transfusion could decrease bleeding volume during caesarean section. ⑤ There were no significant correlation between platelet count and perinatal outcomes(P>0.05).

Conclusion

The incidence of gestational thrombocytopenia is high. But there are no significant correlation between platelet count and perinatal outcomes. Platelet transfusion can reduce bleeding volume in caesarean section.
