氨甲环酸可预防创伤后出血和产后出血所导致的死亡。研究人员开展研究探究氨甲环酸是否可减轻血肿扩张、改善因颅内出血引发的中风患者的预后。Nikola Sprigg等人在12个国家的124家医院的急性中风病房的颅内出血的成年患者中开展一国际性、随机性的安慰剂为对照的临床试验。受试者按1:1被随机分至实验组或对照组,在出现症状的8个小时内,实验组予以氨甲环酸 1g 静推、随后氨甲环酸 1g 静脉维持8h;

氨甲环酸可预防创伤后出血和产后出血所导致的死亡。研究人员开展研究探究氨甲环酸是否可减轻血肿扩张、改善因颅内出血引发的中风患者的预后。

Nikola Sprigg等人在12个国家的124家医院的急性中风病房的颅内出血的成年患者中开展一国际性、随机性的安慰剂为对照的临床试验。受试者按1:1被随机分至实验组或对照组,在出现症状的8个小时内,实验组予以氨甲环酸 1g 静推、随后氨甲环酸 1g 静脉维持8h;对照组组予以对应剂量的安慰剂。主要预后指标是分组治疗90天时的功能状态。

2013年3月1日-2017年9月30日共招募了2325位受试者,其中1161位患者接受氨甲环酸治疗,1164位患者接受安慰剂治疗。最终对2307位(99%)的患者进行预后评估。两组间治疗90天时的功能状态无显著差异(校正优势比[aOR] 0.88,95% CI 0.76-1.03,p=0.11)。虽然治疗7天时,氨甲环酸组的死亡率比安慰剂组的更低(101[9%] vs 123[11%];aOR 0.73,0.53-0.99,p=0.0406),但90天时的死亡率没有差异(250[22%] vs 249[21%];校正风险比 0.92,95% CI 0.77-1.10,p=0.37)。治疗2天、7天、90天时,氨甲环酸治疗的患者比安慰剂组患者的重度副反应均更少(379[33%] vs 417[36%]、456[39%] vs 497[43%]、521[45%] vs 556[48%])。

患者颅内出血后,接受氨甲环酸的早期死亡率和重度副反应减少,但治疗90天时的功能状态与安慰剂组相比并没有明显差异。应开展样本量更大的随机试验来进一步验证氨甲环酸的临床治疗效果。
