摘要
选择 15例胸降主动脉瘤非体外循环下手术病人 ,按阻断期间输血方法将其随机分 3组 ,A组 ( 5例 ) :失血回收并经上肢外周静脉输入 ;B组 ( 5例 ) :用体外循环机泵 ,将出血回收并间断经股动脉插管回输体内 ,输血流量 <50 0ml/min ;C组 ( 5例 ) :途径同组B ,采取“短阵定量快速输入”法 ,即每次输血 2 0 0～ 30 0ml,流量 >150 0ml/min。主动脉阻断时 3组股动脉压均明显下降 ,3组间无统计学差异。经三种不同输血方法处理后 ,阻断 30min时 ,B组桡动脉压显著高于C组 (P <0 0 1) ,而股动脉压明显低于C组 (P <0 0 5) ,但高于A组(P <0 0 5)。C组股动脉压显著高于A组 (P <0 0 1)及B组 (P <0 0 5)。开放主动脉时B组股动脉压显著低于A组 (P <0 0 5) ;与自身桡动脉压比较下降非常显著 (P <0 0 1)。C组能有效地提高阻断期间股动脉压。B组桡动脉压提高显著 ,但股动脉压提高不明显。
In order find effectire method to increase the spinal cord perfusion pressure(SCPP)during aortic crossclamp in descending thoracic aortic aneurysm surgery,we studied the effects of three methods of transfusion on femoral arterial pressure.According to the sites and speeds of transfusion during aortic cross clamping,fifteen patients with descending aortic aneurysm were divided into three groups:Group A,vein on arm by drip;Group B,femoral artery by pump with a speed<500ml/min;Group C,femoral artery by pump with a speed>1500ml/min.The femoral arterial pressure(FAP)was increased by 2.8±0.8mmHg in group A,7.8±1.3mmHg in group B and 33.4±9.4mmHg in group C during transfusion.At 30min of aortic cross\|clamping,the FAP in group C was significantly higher than group A( P <0 01)and Group B( P <0 05).The femoral arterial pressure was increased effectively through transfusion into femoral artery by pump with a speed>1500ml/min and this may lead to a better protection for spinal cord during descending aortic aneurysm surgery.
