【论文摘要】目的 探讨血液灌流(HP)联合高容量血液滤过(HVHF)治疗急性呼吸窘迫综合征(ARDS)的临床效果。 方法2012年5月~2015年5月,将69例ARDS患者随机分为观察组35例,对照组34例。观察组采用HP联合HVHF治疗,对照组采用HVHF治 疗。 结果 观察组治疗后第1天、3天的APACHEⅡ评分、PIP水平均低于治疗前,PO2/FiO2及CL水平均高于治疗前,差异有统计学意义 (P<0.05);观察组治疗后第3天的相关指标与对照组比较差异有统计学意义(P<0.05);治疗后第1天的APACHEⅡ评分低于对照 组,两组差异有统计学意义(P<0.05)。治疗后第1天,两组的TNF-α、IL-6、IL-8水平与治疗前比较均明显降低,且观察组的降低程度 大于对照组,两组差异有统计学意义(P<0.05)。 结论 HP联合HVHF治疗ARDS可有效改善患者的肺功能,从而显著改善其预后。 【论文关键词】急性呼吸窘迫综合征;血液灌流;血液滤过 Effect analysis of hemoperfusion combined with high volume hemofiltration treating acute respiratory distress syndrome LIU Wei-ming JIN Tong-xin LIN Yao-guo QIU Xue-hua CHEN Guan-shuai ICU,Dalang Hosiptal of Dongguan City in Guangdong Province,Dongguan 523770,China [Abstract] Objective To investigate the clinical effect of hemoperfusion (HP) combined with high volume hemofiltration (HVHF) treating acute respiratory distress syndrome (ARDS). Methods From May 2012 to May 2015,69 cases with ARDS were randomly divided into observation grouyp(35 cases) and control group (34 cases).Observation group was treated by HP combined with HVHF,while control group was treated with HVHF. Results APACHEⅡscore,PIP level in observation group after on the 1st day,3rd day treatment was lower than that before treatment respectively,while PO2/FiO2 and CL level was higher than that before treatment respectively,and the difference was statistically significant (P<0.05);there was a statistical difference of the related indexes in observation group after on the 3rd day treatment compared with control group respectively (P<0.05),and after on the 1st day treatment, APACHEⅡscore was lower than that of control group,and there was a statistical difference between two groups (P<0.05).After on the 1st day treatment,TNF-α, IL-6,IL-8 level of two groups was obviously reduced compared with that before treatment respectively,and reduction range in observation group was larger than that of control group,and there was a statistical difference between two groups (P<0.05). Conclusion HP combined with HVHF treating ARDS can effectively improve lung function of patients to improve obviously the prognosis of patients. [Key words] Acute respiratory distress syndrome;Hemoperfusion;Hemofiltration 急性呼吸窘迫综合征(acute respiratory distress syndrome,ARDS)是临床常见的一种疾病,以进行性低氧血症及呼吸窘迫为主要临床表现,肺部影像学表现为非均一性的渗出性病变,对患者的肺功能 及呼吸系统均造成严重影响[1]。ARDS具有起病迅速、发展速度快、预后较差、常出现多器官功能障碍综合征及死亡率高等特点,是临床诊疗中的常见危重症 [2-3]。采用机械通气及保护性肺通气等方法可改善患者的呼吸功能,使ARDS患者的抢救成功率明显提高,但对于ARDS炎症性肺损伤的效果不 佳,ARDS患者的病死率仍然处于较高水平[4]。笔者收集来我院治疗的ARDS患者35例并用血液灌流(hemoperfusion,HP)联合高容量 血液滤过(high volume hemofitration,HVHF)治疗,效果较好。 1 资料与方法 1.1 一般资料 69例ARDS患者均为2012年5月~2015年5月我科收治的病例,男性40例,女性29例,年龄30~81岁,平均 (55.8±9.6)岁,治疗前急性生理学与慢性健康状况评分系统Ⅱ(APACHEⅡ评分)为(24.85±4.7)分,致病诱因为:肺部感染28例,外 科术后8例,急性重症胰腺炎5例,全身性感染9例, 肝衰竭10例, 肺栓塞3例,中毒4例,误吸2例。将患者随机分为两组,观察组35例,对照组34例,两组患者在性别、年龄、APACHEⅡ评分等方面比较差异无统计学意 义(P>0.05),具有可比性。 1.2 方法 观察组采用HP联合HVHF治疗,对照组单独用HVHF治疗。HP治疗过程中使用CRRT机(德国贝朗CRRT),HA330型树脂血液灌流 器(珠海丽珠医用生物材料有限公司)行血液灌流,1次/d,3 h/次,血流量为200~250 ml/min,间隔24 h重复进行,共治疗3次。HVHF常规行股静脉穿刺或右颈内静脉置管建立临时血管通路,必要时为了保证血管通路的畅通可采用双管置管。应用BM25机器 (美国Baxter公司),血液流速为200~250 ml/min,置换液以PORT配方为基础,以患者病情及电解质分析结果为依据,随时调整各种离子的浓度,置换液采用前稀释法输入,置换速度为 4000~6000 ml/h,选用F60聚砜膜滤器,面积为1.2 m2,每24小时更换滤器,8~12 h/次,根据出入量调整脱水量,对无出血倾向的患者以低分子肝素钙抗凝,对有出血倾向的患者用无肝素治疗。 1.3 观察指标 APACHEⅡ评分、氧合指数(PO2/FiO2)、气道峰压(PIP)、肺顺应性(CL);炎症因子:TNF-α、IL-6、IL-8、IL-10水平采用ELISA检测。 |
