目的 觀察體外靜脈靜脈轉流對患者血流動力學的影響。
方法 原位異體肝移植患者14例，術中使用離心泵，部分肝素化方法行體外靜脈轉流。
結果 體外靜脈轉流時間（98.9±23.6）min，轉流量（1 168±260）ml/min，轉流期及新肝5分鐘心排血量（CO）明顯下降，但仍維持在正常水平，體循環阻力（SVR）、肺循環阻力（PVR）轉流30分鐘后明顯增加，心率（HR）、平均動脈壓（MAP）、中心靜脈壓（CVP）、平均肺動脈壓（MPAP）、肺毛細血管楔壓（PCWP）等在轉流期均無明顯變化，新肝早期MAP明顯下降，SVR明顯增加。
結論 無肝期采用離心泵行體外靜脈轉流，有助于穩定血流動力學，但新肝早期仍有明顯血壓下降，主要通過適量快速泵灌注全血來糾正。
