目的:了解75例孕妇妊娠期无出血倾向血小板偏低的血小板参数变化及其临床意义。方法:对75例妊娠期血小板偏低的孕妇采取机测血小板联合标准涂片镜检方法,并用手工计数血小板的方法复检。结果:血小板计数随孕周增加而逐渐下降,妊娠后期较为显著。结论:妊娠中期易引起血小板假性减少,妊娠中期血小板数量持续减少者在妊娠末期易发生妊娠期高血压综合征。
Objective: To investigate the changes of platelet parameters in 75 pregnant women with no tendency of bleeding during pregnancy and its clinical significance. Methods: Seventy-five pregnant women with low platelet count during pregnancy were examined by the combined method of machine-tested platelet and standard smear and re-tested by manual counting of platelets. Results: The platelet count gradually decreased with the increase of gestational age, the latter part of pregnancy was more significant. Conclusion: In the second trimester of pregnancy, platelet pseudophagosis is easily induced. In the second trimester of pregnancy, the number of platelets continues to decrease. Pregnancy-induced hypertension syndrome tends to occur in the end of pregnancy.
