人工肝支持系统在肝功能衰竭中的应用

肝功能衰竭是多种因素引起的严重肝脏损害,在儿科病因更为复杂且病情凶险,传统的内科综合治疗效果欠佳,病死率高.人工肝支持系统也常称为人工肝,是一种能够替代或模拟正常肝脏的部分或全部功能的体外装置,可以使因肝功能衰竭所产生的各种有害物质得以清除,并替代肝脏的部分代谢功能,以维持患者生命.人工肝应用至今已逾50年,其血液净化方式包括血液透析、血浆置换、血液灌流、吸附、全血或血浆滤过以及应用肝组织或细胞研制的有生物效应的治疗方法等.由于肝脏有强大的再生能力,人工肝可为病变肝脏自身再生恢复或接受肝移植尽可能争取时间.随着人工肝支持系统相关技术的不断完善,非生物型人工肝治疗已在临床广泛应用,并取得很好的疗效,成为各种重症肝功能衰竭的重要治疗手段之一.人工肝在儿科临床也有应用报道,但资料有限,仍需要进一步研究和实践.

Abstract：

Despite a combination of all available treatment, the mortality of liver failure is very high,especially in children patients. Artificial liver support methods have been tested for over 50 years. Standard techniques of blood purification like hemodialysis, adsorption, hemo or plasma filtration as well as bioreactorbased approaches using liver cells or tissues have been used. It' s believed that the damaged liver has the ability to return to normal. Artificial liver support systems are expected to be useful for temporary support of liver function. If the liver does not regenerate to normal functions, an artificial liver support system may be useful as a bridge to liver transplantation. In conclusion, artificial liver support method appears to be a reliable therapy for advanced liver diseases and has significantly decreased the mortality of liver failure. Artificial liver support system has been used in children patients as well, but it still needs more researches.
