The results showed that adsorbents, which were grafted with tertiary amine and long spacing arms, had the best adsorption capacities and good blood compatibility. It is hopeful to be used as adsorbent in hemoperfusion for clinical clearance of endotoxin. The influence of original concentration of endotoxin on adsorption and the adsorption mechanism were also investigated.展开更多
文摘目的探讨oXiris-内毒素吸附技术治疗终末期肾病(end-stage renal disease,ESRD)合并脓毒症的疗效。方法回顾性收集2020年1月1日—2023年7月30日于河南科技大学第一附属医院住院治疗的ESRD合并脓毒症患者41例,其中oXiris组22例,连续性静脉-静脉血液滤过(continuous veno-venous hemofiltration,CVVH)联合血液灌流(hemoperfusion,HP)组19例。比较2组患者住院死亡率、ICU住院时长、机械通气时长、连续性肾脏替代治疗时长、机械通气患者数、使用滤器数以及在血液净化治疗开始时及治疗后急性生理与慢性健康评分(acute physiology and chronic health evaluation,APACHE-Ⅱ)、去甲肾上腺素(norepinephrine,NE)用量以及实验室检查结果。结果oXiris组患者机械通气时长少于CVVH+HP组(Z=-3.749,P=0.001)。治疗后oXiris组APACHE-Ⅱ评分(t=-4.481,P=0.001)、NE用量(t=-2.036,P=0.049)、C反应蛋白(Z=-2.850,P=0.004)、白细胞介素-6(Z=-2.512,P=0.012)水平较CVVH+HP组降低。结论oXiris-内毒素吸附技术能有效降低ESRD合并脓毒症患者炎症介质,且效果优于CVVH+HP,具有良好的临床应用价值。
