连续性血液滤过治疗重症急性胰腺炎临床评价

Effects of continuons blood purification on patients with severe acute pancreatitis

摘要:

目的 探讨连续性静脉-静脉血液滤过(CVVH)治疗重症急性胰腺炎(SAP)的临床疗效.方法 对2005年6月至2010年6月天津医科大学第二医院ICU收治的45例SAP患者进行回顾性分析,随机(随机数字法)分为常规治疗组、综合治疗组.常规治疗组22例,采用快速而充分的液体复苏、血管活性药物改善脏器灌注、抑制胰酶分泌、足量广谱抗生素预防感染、早期肠道营养保护肠黏膜屏障等治疗;综合治疗组23例,在常规治疗基础上加CVVH治疗.分别观察两组患者入院时及治疗72 h后急性生理和慢性健康状况(APACHEⅡ)评分、多脏器功能障碍综合征(MODS)评分、肿瘤坏死因子-α(TNF-α)、白介素-6(IL-6)、白介素-8(IL-8)变化.比较两组患者呼吸机治疗时间、ICU住院时间及存活率差异.计量资料组内比较采用配对t检验,各组相关资料构成比及存活率比较采用X2检验,以P<0.05为差异有统计学意义.结果 两组患者入院时APACHEⅡ评分、MODS评分及BUN、Scr、TBIL、ALT、AMS、TNF-α、IL-6、IL-8及CRP比较差异均无统计学意义(P>0.05).与常规治疗组相比,治疗72 h后综合治疗组的临床症状改善明显,APACHEⅡ评分、MODS评分差异有统计学意义(P<0.05);BUN、Scr、TBIL、ALT、AMS、TNF-α、IL-6、IL-8及CRP均下降明显,差异具有统计学意义(P<0.05).综合治疗组和常规治疗组呼吸机治疗时间[(7.6±3.4)d vs. (11.5±4.7)d]、ICU住院时间[(12.3±7.8)dvs.(17.6±9.2)d]及抢救存活率( 86.96%vs.59.09%)比较差异有统计学意义(P<0.05).结论 在常规综合治疗的基础上加用CVVH治疗SAP,能有效清除患者致炎介质和毒素,维持内环境稳定,改善氧合功能,补充营养,提高抢救成功率.

Objective To explore the therapeutic effect of continuous veno-venous hemofiltration (CVVH) on the treatment of severe acute pancreatitis (SAP).Methods All data about forty-five patients with SAP admitted to the intensive care unit (ICU) from June 2005 through June 2010 were reviewed.These 45 patients were randomly (random number ) divided into routine treatment group (n =22 ) and comprehensive treatment group ( n =23 ).In control group,patients were rapidly given with a suffficient liquid support,vasoactive drug to increase organ perfusion,trypsin secretion inhibitor,broad-spectrum antibiotics,enteral nutrition with intestine membrane protective agent in early stage.In the comprehensive treatment group,patients received CVVH integrated with routine treatment.On admission and 72 h posttreatment,the scores of acute physiology and chronic health evaluation Ⅱ ( APACHE Ⅱ ) and multiple organ dysfunction syndrome (MODS),and the results of standard bettery of biochemistry tests indcluding blood urea nitrogen (BUN),serum cratinine (Scr),total bilirubin (TBIL),alanine aminotransferase (ALT),amylase (AMS),C-reactive protein (CRP),TNF-α,IL-6,IL-8 were observed.Time of mechanical ventilation support,length of ICU stay,and survival rate were compared between two groups.Results On admission between the two groups,no statistical significance was seen in the APACHE Ⅱ and MODS score,BUN,Scr,TBIL,ALT,AMS,CRP,TNF-α,IL-6,IL-8 (P > 0.05).But APACHE Ⅱ and MODS score were decreased significantly in comprehensive treatment group than in the routine treatment group,as well as the the level of BUN,Scr,TBIL,ALT,AMS,TNF-α,IL-6,IL-8 and CRP after 72h post-treatment (P<0.05 ).In routine treatment group and comprehensive treatment group,the time of respirator intervention and length of stay in ICU were (7.6±3.4) d vs.(11.5±4.7) d,(12.3±7.8) dvs.(17.6±9.2) d respectively,the statistical significance was shown ( P < 0.05 ).Compared to the comprehensive treatment group ( 86.96% ),the survival rate ( 59.09% ) were lower in routine treatment group ( P < 0.05 ).Conclusions CVVH combined with routine treatment,which can remove inflammatory agents and toxins,maintain homoeostasis,and improve oxygenation,is effective in treatment of SAP and can improve patient survival rate.
