目的探讨妊娠晚期孕妇(孕28～40w)血凝四项指标变化。方法选择妊娠晚期孕妇200例与健康育龄非孕妇200例,测定PT﹑APTT﹑TT﹑FIB四项指标,并对结果进行分析研究。结果两组人群血凝指标中APTT(P<0.05),TT(P<0.05),FIB(P<0.001),PT(P<0.001)均有统计学意义,妊娠晚期孕妇PT、APTT、TT凝固时间均有缩短,FIB明显增高。结论妊娠晚期孕妇的血凝四项指标发生了改变,提示应密切关注其凝血功能的变化,预防并发症的发生.
Objective To investigate the changes of four indexes of hemagglutination during the third trimester of pregnancy (28 ~ 40w pregnant). Methods Two hundred pregnant women in the third trimester of pregnancy and 200 non-pregnant women of childbearing age were enrolled in the study. The four indexes of PT, APTT, TT and FIB were determined, and the results were analyzed. Results The levels of APTT (P <0.05), TT (P <0.05), FIB (P <0.001) and PT (P <0.001) in the two groups were statistically significant The time was shortened, FIB increased significantly. Conclusions The four indexes of blood coagulation in pregnant women in the third trimester have changed, suggesting that they should pay close attention to the changes of coagulation function and prevent the occurrence of complications.
