【摘要】 目的　探讨温氧合血持续灌注对被移植离体心脏保护的临床效果。方法　移植心脏取回后立即行温氧合血高钾 (钾浓度 10～ 2 0mmol/L)持续主动脉根部顺行灌注保护心肌 ,升主动脉开放前停止。结果　 3例移植心脏均自动复跳 ,复苏后心功能良好。结论　温氧合血高钾持续灌注可减少晶体用量 ,缩短供心的缺血时间 ,获得完善的心肌保护效果。更多还原

【Abstract】 OBJECTIVE Objective To study the myocardial protection effect on donor heart by continuous perfusion of warm blood plus potassium .METHODS Continuous perfusion of warm blood plus potassium was initiated immediately after the donor hearts were transferred to the operating room ,and terminated at the aortic cross-clamp release .RESULTS Three transplanted hearts returned to sinus rhythm spontaneously after reperfusion and showed satisfactory cardiac function.CONCLUSION Continuous perfusion of warm oxygenated blood plus potassium can reduce quantity of crystalled used,shorten the time of ischemia,and acquire better myocardial protection effect.更多还原
