心脏术后体外膜肺氧合支持治疗的医院感染分析

目的分析进行体外膜肺氧合(ECMO)支持治疗患者医院感染情况。方法回顾性收集、分析医院2005年8月-2009年8月应用ECMO辅助治疗患者的医院感染资料。结果 120例患者,平均年龄(51.6±13.9)岁,医院感染49例,感染率40.8%;分离病原菌146株,其中革兰阴性菌81株,占55.5%,革兰阳性菌51株,占34.9%,真菌14株,占9.6%;医院感染组患者死亡27例,病死率为55.1%,非医院感染组死亡26例,病死率为36.6%,两组患者病死率差异有统计学意义(P<0.05);logistic回归分析医院感染与二次气管插管以及ICU滞留时间有关。结论医院感染是ECMO支持治疗的常见并发症之一,并且二次气管插管以及ICU滞留时间是其独立危险因素,严格无菌操作,合理使用抗菌药物,以降低病死率。     

肾功能损伤分级系统在成人心脏术后的应用

Objective The aim of this study was to evaluate of adilty of two acute renal failure-specific scoring systenms (the classification by Bellome et al and the AKIN criteria) for predicting hospital mortality after cardiac surgery in adult patients. Methods Between October 1 st 2006 to Decemjber 31 st 2006, 509 adult patients who ungerwent coronary artery bypass grafting (CABG) and/ or valve operation were enrolled in this study. The medical data collection included gender, age, types of operation, perioperative he- modynamic parameters, urine output, biochemical parameters and outcome. Renal function was assessed daily according to the classi- ficatinn by Bellomo and the AKIN criteria, respectively. As references, Acure Physiology and Chronic Health Evaluation(APACHE) Ⅱ and Sepsis-related Organ Failure Assessment (SOFA) score were also calculated. Resuits Three hundred and forty-one patients were male (67.0%), and 168 were female (33.0%), mean age was (56.2±12.0) years old. Tnree hundred and nine patieats un- derwent CABG, 182 underwent valve operation and 18 underwent CABG plus valve operation, Mean duration of ventilation support was (20.4±17.7) houra, and the ICU stay was (1.4±1.0) days. Postoperative hospital stay was (13.8±9.1) days. According to the classification by Bellomo., the highest in-hospital mortality was 52.9% in ARFS group. Mahiplicatinn of in-hospital morality rate was abserved (X2 for trend, P<0.01) in 0.4% (non-ARF), 1.2% (stage 1), 12.0% (stal～ 2) and 32.4% (stage 3) of pa- tients based on the AKIN criteria. By applying the area under the receiver operating characteristic ourve, the classification by Bellomo and the AKIN criteria had good discriminative power. Furthering, multivariate logistic regression analysis verified that the Odds Ratio of the AKIN criteria was 5.478 (P =0.028, 95% Confidence Interval 1.027- 24.856), after adjusting for gender and age. Con- clusion Analytical data confinned good discriminative power of both the AKIN criteria and the classification by Bellomo for predicting hospital mortality of adult postoperative patient with ARF.

肾功能分级在成人心脏术后肾功能衰竭的应用

Objective To evaluate the ability of the RIFLE classification to predict hospital mortality in adult patients who underwent cardiac surgery. Methods From October Ist 2006 to December 31st 2006, five hundred and nine adult patients who underwent coronary artery bypass grafting and/or valve operation were enrolled in this study. Renal function was assessed daily according to the RIFLE classification, meanwhile, APACHE Ⅱ score and SOFA score were also evaluated, as well as the maximum scores were recorded. Results Mean duration of ventilation support was 18(14 - 19) hours, the time of ICU stay was 1.4 ± 1.0 days, and the time of postoperative hospital stay was 12. 0(10.0- 15.0) days. 167 patients (32. 8%) incurred postoperative ARF according to the RIFLE classification. The overall mortality was 4. 3% (22/502). A significant increase (P < 0. 01) was observed for mortality based on RIFLE classification. By applying the area under the receiver operating characteristic curve, the RIFLE classification had more powerful discrimination power [0. 933, (95% CI 0. 872 -0. 995) ,P <0. 001]. Conclusions ARF is one of the major complications in postcardiotomy patients. Analytical data suggested the good discriminative power of the RIFLE classification for predicting inpatient mortality of adult postoperative patient with ARF, and the RIFLE classification is simple and practically performed. According to the RIFLE classification, patients with RIFLE class I or class F incur a significantly increased risk of in-hospital mortality compared with those who never develop ARF.

无创正压通气在心脏手术后急性左心衰竭患者的应用

目的:观察无创正压通气(NPPV)治疗心脏手术后,急性左心衰竭患者的临床疗效。方法:分析2012年7月至2013年6月期间,56例非体外冠状动脉旁路移植(OPCABG)术后发生急性左心衰竭的患者的临床资料,其中男性39例,女性17例,年龄48~65岁,平均年龄(57±5)岁。患者被随机分为对照组(28例)及NPPV组(28例),对照组给予常规治疗并辅以高浓度氧气吸入;NPPV组患者常规治疗同时应用无创正压通气治疗。比较两组患者治疗前后心率(HR)、呼吸频率(RR)、血乳酸(Lac)、动脉血气等以及二次气管插管、监护室停留时间等指标的变化。结果:对照组中1例患者因大面积脑梗死死亡,其余患者均存活出院。NPPV组中1例患者因无法耐受无创正压通气转为有创机械通气,1例因治疗失败二次插管;NPPV组患者二次气管插管[(2)vs.(12)例,P=0.001]及监护室停留时间[(4.3±1.1)vs.(7.3±1.5)h,P0.001]明显少于对照组;两组患者治疗后各指标明显好于治疗前,NPPV组改善较对照组更为显著。结论:NPPV可以明显改善OPCABG术后左心衰竭患者的缺氧状况,降低二次气管插管的概率,缩短监护室停留时间。
