原位肝移植应用静脉-静脉转流的酸碱状态

Observation of Acid Base Status during Clinical Orthotopic Liver Transplantation with Veno venous Bypass

总结６例原位肝移植术。在无肝期使用离心泵行体外静脉－静脉转流。术期血气分析结果显示，与转流前相比，ｐＨ变化不大，在７．３５～７．４５范围内，ＢＥ变化轻微，未低于－５ｍｍｏｌ／Ｌ，表明体外静脉转流下原位肝移植术能避免严重的代谢性酸中毒，所有病人术后恢复良好。

Six end phase liver patients received orthotopic liver transplantation. Veno venous bypass was performed during anhepatic phase. The acid base and blood gases analysis showet that BE slightly decreased at 60 min on bypass and pH was in between 7 35 and 7 45. It is concluded that the clinical ortholopic liver transplantation under veno venous bypass could effectly avoid metabolic acidosis.
