摘要
目的:研究连续性肾替代治疗(CRRT)对外周血中肿瘤坏死因子(TNF),白细胞介素1β(IL1β),白细胞介素8(IL8)和内皮衍生血管舒张因子(一氧化氮,NO)浓度的影响。方法:9例重症急性肾衰(ARF)患者在明确诊断之后行CRRT,每天持续10~12h。采用动静脉内瘘或中心静脉留置单针双腔导管建立血管通路,AK10血泵建立体外循环,血滤器采用FH66D型(聚酰胺膜,06m2)。治疗前和治疗1h,2h,3h,6h,9h和12h(或结束时)取血和超滤液检测TNF,IL1β,IL8和NO的浓度。结果:9例患者均存活且脱离肾脏替代治疗。四种细胞因子在超滤液中均未能检出。CRRT开始1h后外周血中TNF浓度轻度升高,但在治疗过程中缓慢降低,6h时达到最低水平,与治疗前和治疗1h相比差异显著(1064±522ng/L比1678±789ng/L和1722±735ng/L,P值分别<005和<001),随后直到12h时,其浓度基本稳定无显著变化;IL1β水平在治疗后有下降趋势,6h降至最低值,但与治疗前相比差异不显著,6~12h间有所回升,IL8浓度也呈同样变化趋势。NO水平在CRRT开始后亦缓?
