【摘要】 目的:分析血栓弹力图(TEG)在产科妊娠晚期孕妇中的应用价值。方法:选择笔者医院2019年7-12月收治的452例妊娠晚期孕妇,根据产后出血情况分为观察组(出血量≥500 ml)和对照组(出血量<500 ml),对比两组TEG参数(CI值、MA、α角、K、R)和常规凝血指标(TT、PT、APTT、Fib值)。结果:观察组产前CI值、MA值、α角均低于对照组,观察组K、R时间长于对照组,差异均有统计学意义(P<0.05)。观察组产前PT、APTT值均高于对照组,差异均有统计学意义(P<0.05),两组产前TT、FIB比较差异无统计学意义(P>0.05)。TEG预测产后大出血准确率(91.40%)、灵敏度(84.75%)均高于凝血四项(76.92%、67.79%),差异均有统计学意义(P<0.05)。结论:TEG指标能准确反映妊娠晚期孕妇凝血功能状态,预测产后出血准确率和灵敏度均高于常规凝血四项指标,能辅助评估妊娠晚期孕妇产后出血的风险,指导临床采取相应预防和治疗措施。

[Abstract] Objective: To analyze the application value of thrombelastogram (TEG) in obstetric pregnant women in the third trimester. Method: A total of 452 pregnant women in the third trimester from July to December 2019 in the authors hospital were selected and were divided into the observation group (blood loss≥500 ml) and the control group (blood loss<500 ml) according to the postpartum hemorrhage. The TEG parameters (CI, MA, α Angle, K, R) and conventional coagulation parameters (TT, PT, APTT, Fib) were compared between the two groups. Result: The Antenatal CI value, MA value and α Angle in the observation group were all lower than those in the control group, K and R in the observation group were longer than those in the control group, the differences were statistically significant (P<0.05). The prenatal PT and APTT values in the observation group were higher than those in the control group, the differences were statistically significant (P<0.05), while there were no statistically significant differences in the prenatal TT and FIB values of the two groups (P>0.05). The accuracy (91.40%) and sensitivity (84.75%) of TEG in predicting postpartum massive hemorrhage were higher than the four items of coagulation (76.92% and 67.79%), the differences were statistically significant (P<0.05). Conclusion: The TEG index can accurately reflect the coagulation function of pregnant women in the third trimester, and it is higher than the four indexes of conventional coagulation in predicting postpartum hemorrhage in accuracy and sensitivity. It can assist to evaluate the risk of postpartum hemorrhage in pregnant women in the third trimester, and guide clinical preventive and therapeutic measures.

产后出血一直是产妇死亡的首要原因,其中凝血功能障碍是产后出血的四大原因(宫缩乏力、产道损伤、胎盘因素和凝血功能障碍)之一。研究出能更准确诊断妊娠晚期孕妇凝血功能的指标,对预测产后大出血、指导产妇合理用血很有必要。妊娠期是女性特殊的生理过程,孕妇体内发生一系列适应性变化,其中血液成分也有很大的改变,特别是妊娠晚期的变化更为明显[1-2]。孕晚期凝血状态直接关系预后,正确评估凝血功能状态能有效预防多种疾病,并指导临床治疗,改善预后;高凝状态会增加血栓形成风险及子痫前期风险,而血小板减少的低凝状态会导致产后大出血、胎死腹中、新生儿颅内出血等严重不良事件[3]。产前低凝状态可导致产后出血风险增加,传统凝血功能检测只能反映凝血过程中部分状态,在产后大出血预测中具有局限性[4]。为此笔者对比研究产后不同出血情况的孕妇在孕晚期时常规凝血四项指标和血栓弹力图指标,以常规凝血四项指标为对照,分析血栓弹力图在该领域上的应用价值,报道如下。……
