Abstract：Objective To make a comparison between noninvasive blood pressure (NIBP) and invasive blood pressure (IBP). Method Totally 450 patients undergoing selective surgery received radial artery or dorsalispedis artery puncture and catheter under local anesthesia to figure out the difference between NIBP and IBP. Results The systolic blood pressure difference of IBP from different positions and NIBP were as follows:left radial artery group (18.20 ± 0.67, 15.27 ± 0.62) mmHg, right radial artery group (18.54 ± 0.79, 14.68 ± 0.77) mmHg, left foot dorsal artery group (41.98 ± 2.26, 40.54 ± 1.77) mmHg and right foot dorsal artery group (37.57 ± 0.01, 37.93 ± 2.90) mmHg. The noninvasive systolic blood pressure difference between left and right arms was (2.84 ± 0.45) mmHg, the noninvasive diastolic blood pressure difference (3.19 ± 0.34) mmHg, and the noninvasive mean blood pressure difference (2.85 ± 0.35) mmHg. The NIBP of right arm was higher than that of left arm. Conclusions IBP is higher than NIBP, and the invasive artery systolic blood pressure is about 20mmHg higher than noninvasive systolic blood pressure. Meanwhile we confirm that systolic blood pressure gradually rises over 30 years old, and diastolic blood pressure increases while gradually declines after 50.
