Stroke:轻型脑卒中 哪些情况需开始静脉溶栓治疗?

2018年7月,发表于《Stroke》上的一项研究,考察了静脉溶栓治疗轻型脑卒中的影响因素。

背景&目的:2015年更新的美国食品药品监督管理局(FDA)溶栓说明书改变了许多禁忌证。因此,研究者旨在探讨影响轻型脑卒中静脉溶栓治疗决策的临床因素。

方法:一个专家小组选择了7个因素创建一系列情景问卷调查:国立卫生研究院脑卒中量表(NIHSS)、NIHSS量表的主要神经缺损部分、基线功能状况、先前缺血性脑卒中、先前脑出血、近期抗凝药物使用和治疗第1 h内症状的临时模式。使用部分析因设计(150个情景)为7个主要因素提供无混淆的作用估计,以及NIHSS的一阶交互作用。通过电子邮件将调查问卷发送给全国神经学家、急诊医生和同事组织。临床医生被随机分配至15个情景的10组之一。临床医生以0-5分的评分报道给予阿替普酶的客观可能性;量表分类被定为从0%到100%的6个概率。采用联合统计学分析。

结果:来自194名美国临床医生的反应得到156份完整的情景数据:74%为男性,平均年龄46岁,80%为神经病学家。单个情景的治疗平均概率范围是6%到95%。治疗概率从NIHSS评分=1分的24%增加到NIHSS评分=5分的41%。联合模型占总观察反应变异的25%。相比较,一个考察所有可能的相互作用模型占变异的30%。7个因素中,4个因素的加和占联合模型中总体相对重要性的58%,包括先前脑出血(18%)、近期抗凝药物使用(17%)、NIHSS评分(13%)和先前缺血性卒中(10%)。

结论:四个主要变量的加和仅占静脉输注阿替普酶治疗决策相关总变异的一小部分(<15%),反映出高度的可变性和复杂性。未来研究应该考虑其他变量,包括临床医生特征。
