目的探讨连续性肾脏替代治疗(CRRT)对热射病合并多器官功能障碍综合征(MODS)的治疗价值及其疗效。方法对2010年7月15日至8月30日在本院采用CRRT治疗合并MODS的19例热射病患者的临床资料进行回顾性分析。所有患者采用连续性静-静脉血液滤过(CVVH)模式,CVVH置换液初始温度为28~32℃,持续2.0~2.5 h,之后置换液维持36℃。观察患者的预后及不良反应,监测患者CRRT治疗前后的体温、心率(HR)、平均动脉压(MAP)、急性生理学与慢性健康状况评分系统Ⅱ(APACHEⅡ)评分、氧合指数(PaO2/FiO2);检测血清尿素氮(BUN)、肌酐(SCr)、肌红蛋白(Mb)、肌酸激酶(CK)、丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)及动脉血乳酸(Lac)水平。结果15例痊愈或好转,4例死亡。与治疗前比较,经CVVH治疗后患者体温、HR(次/min)、MAP(mm Hg,1 mm Hg=0.133 kPa)、APACHEⅡ评分(分)、PaO2/FiO2(mm Hg)均明显改善(体温:36.8±0.2比41.6±0.3,HR:93.6±10.3比132.5±11.4,MAP:69.8±9.9比45.2±7.7,APACHEⅡ评分:12.3±3.9比29.6±4.6,PaO2/FiO2:213.6±95.4比126.5±87.4,均P<0.05);BUN(mmol/L)、SCr(μmol/L)、Mb(μg/L)、CK(U/L)、ALT(U/L)、AST(U/L)、Lac(mmol/L)均显著降低(BUN:23.9±5.3比42.6±5.4,SCr:123±47比356±51,Mb:201±45比468±39,CK:217±32比843±41,ALT:79±36比894±88,AST:57±28比867±92,Lac:3.5±2.4比16.6±3.9,均P<0.05)。CRRT治疗过程中,血流动力学稳定,无明显副作用发生。结论 CRRT可有效降低热射病患者核心体温,清除BUN、SCr、Mb等代谢产物,减轻炎症反应,支持肝、肾等重要器官功能。CRRT治疗合并MODS的热射病患者安全、有效。
Objective To investigate the value and efficacy of continuous renal replacement therapy(CRRT) for treatment of heat stroke patients complicated by multiple organ dysfunction syndrome(MODS). Methods The clinical data of 19 heat stroke patients complicated by MODS admitted into the hospital in a period from July 15,2010 to August 30,2010 and treated by CRRT were analyzed retrospectively. Continuous venovenous hemofiltation(CVVH) mode was used in all patients and the initial temperature of replacement fluid range was 28℃to 32℃persisting in 2.0 to 2.5 hours and afterward it maintained at 36℃. Prognosis and adverse effect were observed,the patients' body temperature,heart rate(HR),mean arterial pressure(MAP),acute physiology and chronic health evaluationⅡ(APACHEⅡ)scores,oxygenation index(PaO2/FiO2),the levels of serum urea nitrogen(BUN),serum creatinine(SCr), myoglobin(Mb),creatine kinase(CK),alanine aminotransferase(ALT),aspartate aminotransferase(AST)and arterial lactate(Lac)were monitored before and after CRRT treatment. Results Fifteen patients were cured or improved,and 4 died. Compared with those before CRRT treatment,body temperature(℃),HR(bmp),MAP(mm Hg,1 mm Hg=0.133 kPa),APACHEⅡevaluation(score),PaO2/FiO2(mm Hg)were significantly improved(body temperature:36.8±0.2 vs. 41.6±0.3,HR:93.6±10.3 vs. 132.5±11.4,MAP:69.8±9.9 vs. 45.2±7.7,APACHEⅡ:12.3±3.9 vs. 29.6±4.6,PaO2/FiO2:213.6±95.4 vs. 126.5±87.4,all P〈0.05);the levels of BUN(mmol/L),SCr(μmol/L), Mb(μg/L),CK(U/L),ALT(U/L),AST(U/L),Lac(mmol/L)were significantly reduced after the treatment(BUN:23.9±5.3 vs. 42.6±5.4,SCr:123±47 vs. 356±51,Mb:201±45 vs. 468±39,CK:217±32 vs. 843±41,ALT:79±36 vs. 894±88,AST:57±28 vs. 867±92,Lac:3.5±2.4 vs. 16.6±3.9,all P〈0.05). In the process of the treatment,hemodynamics was stable,and no obvious side effects occurred. Conclusion CRRT treatment can exac
