麻醉方式对急性后循环脑卒中血管内治疗患者神经功能结局的影响

目的:比较急性后循环缺血性脑卒中患者在血管内治疗时选择清醒镇静和全身麻醉两种方式对患者神经功能结局的影响。方法:回顾性分析2017年1月至2022年12月在急性卒中质量评估与管理在线数据库(来源于CASE-Ⅱ研究,NCT04487340)登记的656例急性后循环脑卒中血管内治疗患者的临床资料,根据麻醉方式不同分为清醒镇静组(163例)和全身麻醉组(493例)。倾向性评分匹配后428例患者纳入分析,其中清醒镇静组(155例),全身麻醉组(273例)。比较两组手术方式、病因分型、血管再通情况、24 h出血转化、3个月改良Rankin量表(mRS)评分和3个月死亡的差异,采用二元logistic回归分析不同麻醉方式对神经功能结局等的影响。结果:倾向性评分匹配后,清醒镇静与全身麻醉患者除手术方式差异有统计学意义(P<0.01),两组病因分型、血管再通情况、出血转化、3个月mRS评分和3个月死亡差异均无统计学意义(均P>0.05)。二元logistic回归分析结果显示,清醒镇静与全身麻醉患者在血管内治疗后良好功能结局方面差异无统计学意义(OR=1.151,95%CI:0.751~1.765,P>0.05),在患者3个月mRS评分3分及以下、3个月mRS评分4分及以下、3个月死亡、血管再通良好和24 h出血转化方面差异也无统计学意义(均P>0.05)。结论:对于接受血管内治疗的后循环脑卒中患者,采用清醒镇静或全身麻醉对患者神经功能结局无明显影响。

IDENTIFICATION OF A LINEAR FLOW-CONCENTRATION SYSTEM WITH SEVERAL DEGREES OF FREEDOM AND FORMULAS FOR EVALUATION PARAMETERS OF YANGTZE FLOW CONCENTRATION CURVE

Ⅰ. LINEAR LUMPED FLOW-CONCENTRATION SYSTEM WITH SEVERAL DEGREES OF FREEDOM On account of the nonuniformity of rainfall in spatial distribution, the computation of basin-flow concentration or river-network flow concentration, based on the subareas divided by isochrones and tributaries respectively, the river channel flow concentration curve is different from the computation of flow concentration for a river reach with tributaries iatervening in the upper and lower sections under concrete conditions. But there exist
