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.
背景
在这项研究中，我们试图寻找肱动脉（bBP）测量的血压（BP）与右臂桡动脉（rBP）评估的血压之间的关系。
方法
本研究纳入了 315 例患者。排除了患有周围血管疾病、手臂皮肤伤口或皮下组织感染的患者。在麻醉诱导后 15 分钟的平衡和稳定期后，使用带有成人袖带和婴儿袖带的振荡式装置依次获得三个 bBP 和 rBP 记录。每个 BP 的顺序是随机的。
结果
bBP 明显低于 rBP（P<0.05）。这两个值在收缩压（SBP）、舒张压（DBP）和平均血压（MAP）上的差异分别为 13-18mmHg。rBP 与 bBP 呈正相关（r=0.872、0.754、0.765；P<0.001、<0.001、<0.001；SBP、DBP、MAP，分别）。
结论
在临床实践中，可以使用适当的袖带通过对 rBP 的无创测量来评估 bBP 值。
