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.     

前列腺素E1在老年患者非体外循环冠状动脉旁路移植术中的应用

目的探讨前列腺素E1(PGE1)对非体外循环冠状动脉旁路移植术(OPCAB)后患者的作用,以确定其疗效。方法选取我科2005年10～12月行OPCAB的老年患者40例,随机分为两组,每组20例。对照组患者接受常规治疗;PGE1组患者在返回ICU后静脉持续泵入PGE1制剂(剂量为5～20ng/kg.min),维持24～48h。于术后不同时间点监测心脏指数、体循环阻力、肺血管阻力等血流动力学指标,测量红细胞压积、凝血指数、动脉血氧分压、血清肌酐(Cr)及尿素氮(BUN)等指标,并进行比较。结果PGE1组患者术后体循环阻力和肺血管阻力均较对照组明显下降(P<0.05),而心脏指数则显著升高(P<0.05)。两组患者术后红细胞压积均下降,凝血功能术后当天下降、术后第1d升高,但PGE1组高凝状态较对照组明显减轻(P<0.05);术后两组患者的Cr和BUN水平均较术前升高,但PGE1组较对照组含量低(P<0.05)。结论PGE1在OPCAB患者术后恢复中发挥了有益的作用。

老年人心血管手术后急性肾功能损伤预后评价的临床观察

目的 探讨急性肾功能损伤(acute kidney injury,AKI)分级系统对老年心脏手术后患者预后的预测价值. 方法 收集2006年10月至2007年1月首次行冠状动脉移植术和(或)心脏瓣膜植换术的老年患者资料,记录患者性别、年龄、手术类型、尿量、血牛化指标和临床转归等,按照AKI网络工作组(acute kidney injury network,AKIN)分级及急性生理学和慢性健康状况评价系统(APACHEⅡ)评分在术后对患者进行评分并记录最高分值. 结果 225例患者中男169例(75.1%),女56例(24.9%),平均年龄(66.7±5.0)岁.住院病死率5.8%(13例).根据AKIN分级,最终发生不同程度AKI的患者占55.6%(125例);AKIN分级1级(96例)、2级(11例)、3级(18例)患者的住院病死率分别为2.1%(2例),9.1%(1例)和50.0%(9例).病死率随AKIN分级的递增有升高趋势(P<0.01).受试者工作特征曲线下面积分析AKIN和病死率具有相关性;Logistic回归分析结果显示,随AKIN分级的递增,相对死亡危险性增加. 结论 AKI是老年人心脏手术后的常见并发症之一,可增加术后病死率.AKIN分级系统对此类患者的预后及住院死亡有良好预测价值.     

体外膜肺氧合辅助后高胆红素血症的临床意义

Objective The incidence of post-operative hyperbilimbinemia, which is associated with poor outcomes in patients, was reported to be increased in recent years though it has been a rare complication for cardiac operations. Post-opera-tive impairment of liver function is highlighted. We evaluated the incidence and prognosis of post-operative hyperbiliruhinemia in adult patients who underwent cardiotomy with extracorporeal membrane oxygenation (ECMO) support. Methods Sixty-five adult patients who had received ECMO support after cardiac surgery from 2004 to 2008 were enrolled and evaluated retrospec-tively. Post-oporative hypethilirubinemia was defined as the serum level of the total bilirubin more than 51.3 μmol/L during postoperative period. Demographic and clinical data included gender, age, types of surgery, perioperative hemodynamic param-eters, biochemical variables, duration of the ventilation support, ICU stay and outcomes. Results The mean age of the pa-tients was (50.1 ± 13.9) years, forty-six patients(70.8%) were male. The main cardiac procedures were heart transplanta-tion for 9 patients, coronary artery bypass grafting and/or valve operations for 47 patients, congenital heart disease correction for 4 patients and other operations for 5 patients. Among all patients, fifty-one patients(78.5%) were weaned from ECMO succeas-fully and thirty-thrce patients were discharged from hospital. The overall mortality rate was 49.2%. Overall incidence of post-operative hyperbilirubinemia was 55.4%. In patients with postoperative hyperbilirubinemia, the mean peak value for serum to-tal bilirubin was 104.8 (68.5-156.7) μmol/l. The hospital mortality in the hyperbilirubinemia group was significantly higher than that in the non-hyperbilirubinemia group(66.7% vs. 27.6%, P <0.01). Moreover, postoperative hypethilirubinemia (adds ratio = 3. 895, 95% confidence interval, 1.088 - 13.947 ; P = 0.037) and SOFA score (odds ratio = 1.214, 95% confidence interval, 0.987 - 1.494, P = 0.047) and APACHE Ⅲ score (odds ratio = 1.096, 95% confidence interval, 1.028 - 1.169 ; P = 0.004) were associated with hospital mortality after adjusting for preoperative levels of the total bilirubin, direct bilirubin, gender and age. Conclusion Postoperative hyperbilirubinemia is one of the complications in adult patients who undergo cardiotomy with ECMO support, and is associated with increased hospital mortality.
