摘要 目的探讨不同剂量血液滤过治疗小儿脓毒症休克的临床效果及对安全性的影响。方法将小儿脓毒症休克60例按照随机数表法分为A、B、C组各20例;所有患儿均在确诊为脓毒症休克的6 h内进组进行连续性静脉血液滤过(continuous veno-venous hemofiltration,CVVH)治疗,A组置换量为65 mL·kg^(-1)·h^(-1),B组置换量为50 mL·kg^(-1)·h^(-1),C组置换量为35 mL·kg^(-1)·h^(-1);对比3组接受血液滤过0 h、24 h、48 h、72 h的氧合指数、血清肌酐、血尿素氮、动脉血乳酸、血清炎症因子(IL-6、IL-10和TNF-ɑ)、降钙素原(procalcitonin,PCT),并统计3组28 d病死率。结果 3组氧合指数均呈逐渐升高趋势,升高幅度依次为A组、B组和C组;血清肌酐A组和B组均呈逐渐下降趋势, C组上下波动;血尿素氮A组呈逐渐下降,B组和C组上下波动;3组IL-6呈逐渐下降趋势,降幅依次为A组、B组和C组;3组IL-10均呈先升高,后降低;TNF-ɑA组和B组逐渐降低,C组先升高,后降低;以上6项指标在组间、时点间以及组间·时点间交互作用差异均有统计学意义(P<0.05)。3组PCT、血乳酸水平均呈逐渐下降趋势,下降幅度依次为A组、B组和C组,其组间、时点间、组间·时点间交互作用差异均有统计学意义(P<0.05)。28 d病死率A组10.0%,B组30.0%,C组50.0%,A组病死率最低,与C组差异有统计学意义(P<0.05)。结论大剂量组能较好地改善脓毒症休克患儿氧合及肾功能,减轻其炎症反应,降低其病死率和提高其预后效果。
