患者右侧桡动脉与肱动脉无创血压值的关系

Relationship between noninvasive brachial artery blood pressure and radial artery blood pressure ofthe right arm of patients

目的研究患者右侧桡动脉（B）与肱动脉无创血压值（R）的关系。方法随机选择全麻下手术前的患者295例，年龄（47±16）岁，男：女比例为149：146，身高（163±8）cm，体质量（61．2±7．8）kg。排除主动脉或外周血管疾病、右臂外伤或感染等情况者。待其生命体征平稳后分别采用成人袖带及儿童袖带测量其右上肢肱动脉与桡动脉血压无创血压值，并记录为收缩压（SBP）／舒张压（DBP）及平均压（MAP）。用SPSS16．0统计软件进行数据分析，肱、桡动脉血压相关性分析采用线性回归法，各区问的桡、肱动脉差值的比较采用单因素方差分析，各区间两两比较采用SNK-q法。结果成人袖带所测右上臂肱动脉血压明显低于儿童袖带所测右前臂桡动脉血压，它们之间具有显著的线性相关性[r=0．841（SBP）、0．808（DBP）、0．833（MAP），均P〈0．01]。肱、桡SBP、DBP和MBP之间的差值为13-18mmHg（1mmHg=0．133kPa）。结论选择儿童袖带测量患者桡动脉血压可较好的反映肱动脉血压值的变化。

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 ninety- five 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.
