摘　　要：目的观察并初步评价在严重烧伤早期进行连续性血液净化治疗的可行性及临床疗效。方法选择笔者单位2013年1月-2015年7月收治且符合入选标准的41例严重烧伤患者，按随机数字表法并结合患者个人意愿分为常规治疗组21例和血液净化组20例。常规治疗组患者按照严重烧伤救治原则给予常规治疗；血液净化组患者在常规治疗基础上，人院后及时进行连续性静脉．静脉血液透析滤过模式的血液净化治疗，持续至伤后72h。伤后1、2、3d，观察并记录患者的生命体征、补液量、尿量；采集患者股动脉血，检测乳酸、碳酸氢根、剩余碱，并计算氧合指数。伤后12、24、48、72h，采集患者股静脉血，检测白细胞计数、血小板计数、中性粒细胞、心肌型肌酸激酶同工酶、肌酸激酶、乳酸脱氢酶、AST、ALT（计算AST／ALT比值）、肌酐、尿素氮、血糖。随访记录患者伤后2个月内感染、脓毒症、MODS发生率和病死率。对数据行X2检验、重复测量方差分析、t检验、Wilcoxon检验，并进行Bonferroni校正。结果41例患者均顺利完成试验，无脱落病例。（1）伤后1～3d，2组患者生命体征、补液量和尿量比较，差异均无统计学意义（t值为-1．64～1．48，P值均大于0．05）。（2）与常规治疗组比较，血液净化组患者乳酸水平仅于伤后2、3d显著降低（z值分别为-2．37、-2．46，P值均小于0．05），碳酸氢根、剩余碱水平仅于伤后3d显著降低（t值均为-2．51，P值均小于0．05）。血液净化组患者伤后3d氧合指数为（370±98）mmHg（1mmHg=0．133kPa），显著高于常规治疗组的（305±81）mmHg（t=2．27，P〈0．05）。（3）伤后12～72h，2组患者白细胞计数、血小板计数、中性粒细胞、肌酸激酶、乳酸脱氢酶、AST、ALT、AST／ALT比值比较，差异均无统计学意义（t值为-1．47～1．19，Z值为-1．58～-0．03，P值均大�Objective To observe and primarily evaluate the feasibility and validity of continuous blood purification （CBP） during the early stage of severe burn. Methods Forty-one patients with severe burn admitted to our ward from January 2013 to July 2015, conforming to the study criteria, were divided into conventional treatment group （CT, n = 21 ） and blood purification group （BP, n = 20） according to the random number table and patient＇s personal consent. Patients in group CT received CT conforming to the traditional resuscitation principle for severe burn, while patients in group BP received CT and blood purification treatment in the mode of continuous venous-venous hemodiafihration in addition up to post injury hour （PIH） 72. On post injury day （PID） 1, 2, 3, the vital signs, volume of fluid input, and volume of the urine output were observed and recorded; femoral artery blood was drawn to determine lactate, bicarbonate radical, and base excess, and oxygen index was calculated. At PIH 12, 24, 48, 72, femoral vein blood was drawn to determine white cell count, platelet count, neutrophils, creatine kinase-MB, creatine kiuase, lactic dehydrogenase, aspartate transaminase （AST） , alanine aminotransferase （ALT） , creatinine, urea nitrogen, and blood glucose （the ratio of AST to ALT was calculated）. The incidence of infection, sepsis, and multiple organ dysfunction syndrome （MODS） and the mortality of patients were recorded during 2 months after injury. Data were processed with chi-square test, analysis of variance for repeated measurement, t test and Wilcoxon test, and the values of P were adjusted by Bonferroni. Results The observation was completed in the 41 patients without exclusion. （ 1 ） There were no statistically significant differences in vital signs, volume of fluid input, and volume of the urine output of patients between two groups on PID 1, 2, 3 （with t values from - 1.64 to 1.48, P values above 0.05 ）. （2） Compared with that in group CT, the level of lactate
