持续性血液滤过在治疗危重症合并电解质紊乱患者中的应用

目的观察持续性静脉-静脉血液滤过(continuous veno-venous hemofiltration,CVVH)在治疗危重症合并电解质紊乱患者中的应用效果和总结其护理经验。方法对246例危重症合并电解质紊乱患者给予CVVH治疗,并测定CVVH治疗前后患者血清K^+、Na^+、Cl^-、肌酐和尿素氮的浓度。结果治疗后患者血清K^+、Na^+、Cl^-浓度明显升高,肌酐和尿素氮均下降,治疗前后比较,差异具有统计学意义(均P<0.05)。结论危重症合并电解质紊乱患者采用CVVH治疗可纠正电解质紊乱,使受损的心、肝、肾等脏器的功能得到恢复;精心的护理是治疗能顺利进行的保证。

Objective To investigate the effect of continuous vein-to-vein hemofiltration （CVVH） on electrolyte disturbances from severe diseases and summarize the nursing strategies. Method 246 patients with severe diseases combined with electrolyte disturbances were managed with continuous vein-to-vein bemofihration, the serum concentrations of K＋、Na＋、Cl^-, Cr and UN before management and after management were tested. Result After management, the serum concentrations of K＋、Na＋、Cl^- were increased significantly and the concentrations of Cr and UN decreased significantly （P 〈 0.05）. Conclusions CVVH may correct the disturbances of electrotypes so as to reduce the damage to organs, accelerate the recovery of heart, liver and kidney. The delicate nursing care is the assurance for the smooth treatment.
