摘要 目的探讨活化血浆凝固时间(APCT)对血小板减低所致出血的预示价值及输注疗效的评估价值。方法血液病患者40名血小板计数(Plt)均<50×109/L,其中有散在出血点或鼻衄症状的24例,无出血症状的16例,有22例进行了血小板输注(其中21例有出血症状)。抽取患者静脉血,以3.8%的拘橼酸钠抗凝后,测定Plt和APCT。结果出血组患者的APCT与未出血组相比明显延长,出血组和未出血组的Plt和APCT分别为(7.9±3.4)×109/L、(104.2±6.2)s,(19.7±14.3)×109/L、(74.0±9.2)s,P<0.05。以APCT≥90s为界点值,对预示血小板减少所致出血的敏感度为100%,特异性为93.7%;以Plt≤15×109/L为界点值,预示敏感度为95.8%,特异性为50.0%。22名患者输注血小板后1,24h的APCT均明显缩短,APCT由输注前的(103.7±11.3)s分别缩短为输注后1h的(60.0±9.7)s、24h的(68.5±9.8)s,P<0.01。18名患者血小板输注后24h的APCT均<80s,其出血症状均消失,但其中有1例CCI、3例PPR显示血小板输注无效;血小板输注后24h的APCT>80s的3名患者的出血症状无明显改善,而CCI、PPR只有1例显示血小板输注无效。结论APCT是血小板预防性输注的良好指征,其特异性明显优于Plt。APCT同时反映血小板数量和质量的变化,能较全面的评估血小板的输注疗效。
