原位肝移植术临床麻醉管理的探讨

目的 探讨成年人原位肝移植术期的变化及麻醉处理。方法 采用全身麻醉或全身麻醉或全身麻醉复合硬外麻醉；无肝期采用体外静脉转流；术中监测动力学、呼吸功能、血气、生化、凝血功能、体温、血糖、尿量及出血量。根据原位肝移植术无肝前期、无肝期、新肝期的特点，给予相应的麻醉处理。结果 无肝期均外静脉转流技术，可以使术中血液动力学埸于稳定。无肝期初期及新肝期理。结果 无肝期均采用体外静脉转流技术，可以使术中血液动

Anesthetic management for patients undergoing orthotopic liver transplantation

Objective To investigate the peri operative changes and anesthetic management during orthotopic liver transplantation (OLT) Methods General anesthesia or general anesthesia combined with epidural anesthesia was applied During the anhepatic phase, extracorporeal veno venous bypass (EVVB) was established Hemodynamics, respiratory function, blood gas, biochemistry, blood coagulation function, body temperature, blood glucose, urinary output and bleeding output were monitored According to the different characteristics of the pre anheptic phase, anheptic phase and neoheptic phase during OLT, the corresponding anesthetic management was supplied Results Applying EVVB during the anheptic phase could keep hemodynamics stable, but in 15 min of the primary anheptic and neoheptic stages a transient circulatory instablity occurred,and the rapid blood volume expansion was required Through comprehensive management, there was no obvious acid base disturbance during the phases The hypocalcemia, hypokalemia and hyperglycemia occurred and thebody temperature changed greatly,to require timly corrective measures Certain coagulative disturbances occurred, to require the supplement of coagulation factors, proper hemostatic drugs and protamine for neutralizing heparin Intraoperatively, anti rejection drugs were required Peri operatively, the blood glucose levels were higher than normal Conclusions Utilizing EVVB during the anheptic phase can be helpful to maintain hemodynamics stable, prevent obvious acidosis and hyperkalemia The anesthetic management during the neoheptic phase should be required to correcte hypothermia, hypocalcemia, hypokalemia, hyperglycemia and disturbence of coagulation
