Abstract:
Objective To investigate the relationship between noninvasive brachial artery blood pressure (B) and radial artery blood pressure (R) of the right arm.Methods Two hundred and ninetyfive patients with 149 males and age of (47 ± 16) years were studied.The height of patients was 163 ± 8 cm,and weight of patients was (61.2 ± 7.8) kg.The patients with peripheral vascular disease,wounds of arm skin or subcutaneous tissue infection were all excluded.Their B (with adult cuffs) and R (with infant cuffs) of the right arm were measured and analyzed after the patients under general anesthesia and stable hemodynamics.The relationships between B and R were analyzed by linear regression,the differences between B and R of each interval were compared using one-way ANOVA and then followed by SNK procedure.Results Right brachial artery blood pressure was significantly lower than radial artery blood pressure.The differences between the two varied from 13 to 18 mmHg in systolic BP (SBP),diastolic BP (DBP) and mean blood pressure (MAP).And linear regression was most applicable to describe their correlation [r=0.841 (SBP),0.808 (DBP),0.833 (MAP),all P＜0.01].Conclusions Radial artery blood pressure measured with infant cuffs can well reflect the variation of brachial artery blood pressure.
