摘要 目的观察去甲肾上腺素对肝移植患者术中血流动力学及乳酸的影响。方法选择50例行非转流经典原位肝移植术患者,随机分为多巴胺组(D组,n=25)和去甲肾上腺素组(N组,n=25)。D组术中持续泵入多巴胺,速率为2~20μg·kg-1.min-1;N组术中持续泵入去甲肾上腺素,速率为0.01~0.4μg·kg-1.min-1,术中两组均调节泵入速率使平均动脉压维持在60~80mmHg。分别记录两组患者麻醉诱导后切皮前(T0)、手术开始后40min(T1)、无肝期40min(T2)、新肝期40min(T3)、术毕(T4)患者的心率(HR)、平均动脉压(MAP)、中心静脉压(CVP)、平均肺动脉压(MPAP)、心输出量(CO)、体循环血管阻力(SVR)、肺循环血管阻力(PVR)及血糖(GLU)、乳酸(LAC)的值。结果与T0相比,两组患者在T2~T4时段HR明显增快,组间比较差异有统计学意义(P<0.05);两组患者在T2与T0时比较,CVP、MPAP、CO明显降低,SVR、PVR明显增高(P<0.05),两组患者在T3时与T2比较,CVP、MPAP、CO明显增高,SVR、PVR明显降低(P<0.05),组间比较差异无统计学意义(P>0.05);与T0相比,两组患者在T1~T4时段GLU、LAC持续增高(P<0.05),组间比较差异有统计学意义(P<0.05)。结论肝移植术期间出现显著的血流动力学及GLU、LAC的变化,去甲肾上腺素在维持肝移植患者术中血流动力学方面优于多巴胺。
