随着临床医学技术的发展，越来越多的肝功能障碍病人可接受手术治疗并安全度过围手术期。肝功能损害是普通外科病人在围手术期可能发生的严重并发症之一。手术创伤、麻醉、应激及严重感染等均会导致肝脏损害。因此，围手术期应严密监测病人的肝功能变化，避免诱发和（或）加重肝脏损害的因素；对于肝功能异常的病人，应全面评估肝脏功能，改善凝血功能，加强营养支持等；避免麻醉药物、感染及缺血等因素加重肝脏损害，安全度过围手术期。

Abstract    With the progress of surgical and anaesthetic management，more and more operations in patients with a high-risk of perioperative liver failure can be performed successfully. Damage of liver function is one of severe complications in surgical patients in perioperative period. Surgical trauma, anesthetic medicines，stress, severe infections and other causes of liver damage should be avoided during operation. Close monitoring and prompt treatment perioperatively are vital to protecting patients from liver damage. Pre-existing liver diseases，preoperative liver function should be assessed comprehensively. Measures should be taken to improve the blood clotting function，nutrition status and to control infection to minimize perioperative liver insults.
