动脉血压直接测量与间接测量的相关性研究

目的探讨动脉血压直接测量值与间接测量值的相关性.方法选择50例冠状动脉造影和PTCA及支架术病人,用Seldinger's法穿刺右股动脉并用多导生理仪直接测量主动脉根部的血压,用标准台式水银柱血压计间接测量肱动脉血压值,二者进行比较.结果动脉血压的收缩压直接测量值与间接测量值有显著相关性(P<0.05),舒张压以变音为准的间接测量值与直接测量值也有显著相关性(P<0.05),且比以消失音为准的间接测量值相关性更强.结论在老年动脉硬化患者间接测量动脉血压可以反映动脉血压的实际水平,但收缩压与动脉实际血压相关性最好,克氏分期法,以变音为准的舒张压更能反映血压的实际值.

On Research of Correlation between Direct and Indirect Measured A rterial Blood Pressure

Objective\ To investigate the correlation between direct and indirect measured arterial blood pressure.Method\ Fifty cases with coronary angiography and PTCA Stenting were recruited and right femoral artery was punctuated with seldinger's method.The direct arterial blood pressure was measured by multichannel physiological recorder;the indirect blood pressure was done by the method of korotkoff with a stethoscope from mercury sphygmomanometer.Result\ The direct systolic arterial blood pressure has a significant correlative with indirect arterial blood pressure (r=0.92,P<0.05),the diastolic pressure has a closed correlative with indirect arterial blood pressure when muffling sound was used as well.Conclusion\ Noninvasive blood pressure has a significant correlative with invasive blood pressure.For the phases of korotkoff,muffling sound is more accurate in getting a diastolic blood pressure.
