Abstract
BACKGROUND: In this study, we attempted to find the relations between blood pressure (BP) measured on the brachial artery (bBP) and BP assessed on the radial artery (rBP) in the right arm. METHODS:Three hundred and fifteen patients were enrolled in this study. Those who had peripheral vascular disease, wounds of arm skin or subcutaneous tissue infection were excluded. After a 15-minute equilibration and stabilization period after inducation of anesthesia, three bBP and rBP records were obtained sequentially using an oscillometric device with an adult cuff and infant cuff, respectively. Order for each BP was randomized. RESULTS: The bBP was significantly lower than the rBP (P<0.05). The difference between the two values varied from 13 to 18 mmHg in systolic BP (SBP), diastolic BP (DBP) and mean blood pressure (MAP) respectively. And the rBP was positively correlated with the bBP (r=0.872, 0.754, 0.765; P<0.001, <0.001, <0.001; SBP, DBP, MAP, respectively). CONCLUSION: The bBP value can be evaluated by the noninvasive measurements of rBP using an appropriate cuff in clinical practice.
