Abstract:

Objective To explore the changes of the inflammatory mediators and myocardial injury duringthe hepato-reperfusion in patients undergoing liver transplantation. Methods A total number of 24 recipients who underwent liver transplantation received general anesthesia. Blood samples were collected from central veinbefore skin incision(T0 baseline),at 1 min of hepato-reperfusion(T1),2 h of neohepatic stage(T2),the end of surgery(T3)and four hours after surgery(T4),24 h after operation(T5). Concentration of TNF-α,IL-6,cardiac troponin I(cTnI),creatine kinase MB(CK-MB)and lactate dehydrogenase(LDH)activity were detected in blood serum. Results All patients completed surgery successfully. Hemodynamic changed obviously during the anhepaticphase and hepato-reperfusion. The serum TNF-α,IL-6,cTnI and CK-MB concentrations and LDH activity at T2-T5 increased significantly compared with the baseline at T0〔TNF-α(ng/L):182±29、89±22、71±26、28±13 vs. 21±8,IL-6(ng/L):1751±255、1420±251、947±219、417±97 vs. 70±18,cTnI(μg/L):0.126±0.045、0.215±0.065、0.252±0.055、0.198±0.045 vs. 0.042±0.018,CK-MB(μg/L):5.1±1.7、10.3±2.2、15.2±2.5、10.3±2.2 vs. 1.6±0.5,LDH(U/L):547±216、620±251、751±255、417±97 vs. 170±58,P < 0.05 or P < 0.01)〕. Conclusion To some degree,myocardial injury could be found during the neohepatic stage in patients undergoing liver transplantation,which may be associated with a great deal of inflammatory mediatorsreleasing. 

摘要:

目的 探讨肝移植患者新肝期血清炎症因子的变化及对心肌的损伤机制。方法 收集 2013 年3 月至 2014 年 10 月天津市第一中心医院 24 例于静吸复合全身麻醉下行原位肝移植术患者。分别于切皮前即刻(T0)、新肝期 1 分钟(T1)、2 小时(T2)、术毕(T3)、术后 4 小时(T4)及 24 小时(T5)采集患者中心静脉血,检测血清中肿瘤坏死因子 -α(TNF-α)、白细胞介素 -6(IL-6)、心肌肌钙蛋白 I(cTnI)、肌酸激酶同工酶(CK-MB )浓度和乳酸脱氢酶(LDH)活性。结果 所有患者均顺利完成手术,术中无肝期和新肝再灌注期血流动力学变化明显。与 T0 比较,T2 ~ 5 血清 TNF-α、IL-6、cTnI、CK-MB 浓度和 LDH 高〔TNF-α(ng/L):182±29、89±22、71±26、28±13 比 21±8,IL-6(ng/L):1751±255、1420±251、947±219、417±97 比 70±18,cTnI(μg/L):0.126±0.045、0.215±0.065、0.252±0.055、0.198±0.045 比 0.042±0.018,CK-MB(μg/L):5.1±1.7、10.3±2.2、15.2±2.5、10.3±2.2 比 1.6±0.5,LDH (U/L):547±216、620±251、751±255、417±97 比 170±58,P < 0.05 或 P < 0.01〕。结论 肝移植患者新肝期存在一定程度的心肌损伤,其机制可能与炎症细胞因子的大量释放有关。
