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.     

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.

肾功能评分在心脏瓣膜术后急性肾损伤的应用

目的:研究旨在探讨肾脏衰竭危险、肾脏损伤、肾功能衰竭、肾功能丧失及终末期肾病(RIFLE)分级,对我院成年心脏瓣膜手术后患者临床转归的应用价值。方法:收集2006年10月至2007年3月首次行心脏瓣膜手术的成年患者资料。记录患者性别、年龄、手术类型、尿量、血生化指标和临床转归等。按照RIFLE分级在术后对患者进行评分并记录最高分值。结果:465例患者,男性182例(39.1%),女性283例(60.9%),平均年龄(50.0±11.9)岁。住院病死率2.4%。根据RIFLE分级,最终发生不同程度急性肾功能损伤(AKI)的患者共占32.0%;R级、I级和F级4组患者的住院病死率分别为:1.4%、7.7%和16.3%,以F级患者的病死率为最高(P<0.01)。受试者工作特征曲线(ROC)曲线下面积分析RIFLE和死亡之间有很好的相关性。结论:AKI是心脏瓣膜手术后的常见并发症之一,明显增加术后病死率。RIFLE分级对此类患者的预后及住院病死率有较好预测能力。

肺复张在冠状动脉旁路移植术后低氧血症的临床观察

目的评价肺复张术(RM)对非体外循环冠状动脉旁路移植手术术后低氧血症患者的疗效以及潜在的不良反应。方法纳入OPCABG术后低氧血症患者(氧合指数<200mmHg)监测并记录有创持续动脉压(artery blood pressure,ABP)、血气分析(arterial blood gas,ABG)。肺复张术采用PCV方法,PC 40cm H2O,PEEP 20cm H2O,持续30s,如果患者出现血压或SPO2明显下降,或出现新发生的心律失常,立即中止肺复张术。结果实施RM患者氧和明显改善(P<0.05),与对照组相比在RM后1h差异显著,6h患者在PEEP升高至一定水平时均会出现一过性动脉压下降,降低PEEP水平后很快恢复;所有病例均顺利出院,未发生气压伤或其他并发症。结论 RM治疗OPCABG术后低氧血症是安全的,可以明显改善患者的氧和状态。     

胸主动脉夹层动脉瘤腔内修复术联合药物治疗稳定型B型主动脉夹层

目的对比分析胸主动脉腔内修复术(TEVAR)联合药物与单纯药物治疗对稳定型Standford B型主动脉夹层患者疗效及安全性的影响。方法回顾性分析本院2015年5月至2016年7月收治的142例稳定型Standford B型主动脉夹层患者的临床资料,按照不同治疗方式分为治疗组(n=71)与对照组(n=71)。对照组患者单纯给予药物治疗,治疗组患者在对照组患者基础上联合TEVAR进行治疗,对比分析2组患者的治疗效果及安全性。结果治疗组患者院内死亡率为8. 45%,对照组患者院内死亡率为18. 31%,2组比较差异具有统计学意义(P 0. 05)。治疗组患者术后并发症发生率为12. 68%,对照组患者并未出现主要并发症,2组比较差异具有统计学意义(P 0. 05)。治疗组患者出院30 d内病死率为0,对照组患者出院30 d内病死率为8. 45%,2组比较差异具有统计学意义(P 0. 05)。术后随访6个月、1年、2年的生存率,治疗组分别为94. 37%、85. 92%、77. 46%,对照组分别为91. 55%、83. 10%、71. 83%,2组比较差异无统计学意义(χ2=0. 351,P=0. 172)。结论 TEVAR联合药物治疗稳定型Standford B型主动脉夹层具有良好的近、中期疗效,但术后相关并发症发生率较高,影响预后生存率,应严格把握手术适应证,选择良好手术时机,谨慎术中操作。
