胺碘酮对房性快速性心律失常危重患者心率控制影响的建模 (AMIRA)
2019年9月24日 更新者:Joe Elie Salem、Groupe Hospitalier Pitie-Salpetriere
目的胺碘酮是控制房性心动过速 (ATs) 危重患者心率的金标准药物;然而,影响其功效的有效剂量和协变量仍然未知。
因此,研究人员对这些患者中胺碘酮诱导的心率降低进行了药效学建模。
方法和结果 这项观察性研究包括 80 名连续接受胺碘酮治疗 AT 的重病患者。
使用非线性混合效应模型,在住院治疗开始后长达 6 天的时间内,对总共 1348 次时间-心率观察和 361 次胺碘酮给药进行了分析。
在重症监护前使用胺碘酮进行预处理、阵发性与持续性 AT、儿茶酚胺输注以及液体和镁负荷是模型中评估的协变量。
对于未接受胺碘酮预处理的患者的阵发性 AT,第一天 300 mg 静脉负荷剂量结合 800 mg 口服剂量,随后口服 800 mg/天,持续 4 天可有效达到 80 次心率和 115 bpm 在第一天,并在接下来的 4 天内保持它。
持续性 AT 患者的相应剂量是其两倍。
使用静脉内镁 (p<0.02) 和液体负荷 (p<0.02) 与更早和更大的心率降低相关,而使用多巴酚丁胺具有相反的影响 (p<0.05)。
结论 在患有 AT 的危重患者中,控制心率所需的胺碘酮剂量受 AT 类型和其他易于测量的情况的影响,这可能允许更好地个体化胺碘酮剂量。
