The purpose of this study was to assess the effects of age, body condition score (BCS) and muscle condition score (MCS) on indirect radial and coccygeal Doppler systolic arterial blood pressure (SAP) measurements in dogs.
Sixty-two privately-owned dogs were enrolled between June and July 2016. The BCS and MCS were determined by two investigators. Blood pressure was measured per published guidelines and using headphones, and the order of measurement site was randomized. Dogs were positioned in right lateral recumbency for radial measurements and sternal recumbency or standing for coccygeal measurements. Associations between SAP and other variables were assessed by correlation coefficients and analysis of covariance.
Radial and coccygeal SAP measurements were moderately correlated ( = 0.45, < 0.01). Radial SAP measurements were higher than coccygeal SAP measurements (mean difference 9 mmHg, < 0.01), but discordance occurred in both directions. No difference was observed between the first measurement taken, the average of measurements 2-6, or the average of all 6 measurements for either the radial (128, 129, and 129 mmHg; = 0.36) or coccygeal (121, 122, and 122 mmHg; = 0.82) site. Associations were not found between SAP measurements for either site and age, weight, BCS, MCS, anxiety score, or cuff size. Heart rate decreased significantly from the start of acclimation to the end of the first data collection series regardless of site ( < 0.01).
Initial measurement site can be based on patient and operator preference given lack of associations with patient variables, but the same site should be used for serial SAP measurements given discordant results between sites.
本研究旨在评估年龄、体况评分（BCS）和肌肉状况评分（MCS）对犬间接桡动脉和尾动脉多普勒收缩期动脉血压（SAP）测量的影响。
2016年6月至7月纳入62只私人饲养的犬。BCS和MCS由两名研究人员确定。按照已发表的指南并使用头戴式耳机测量血压，测量部位的顺序是随机的。犬在右侧卧位进行桡动脉测量，在胸骨卧位或站立位进行尾动脉测量。通过相关系数和协方差分析评估SAP与其他变量之间的关联。
桡动脉和尾动脉的SAP测量值呈中度相关（r = 0.45，P < 0.01）。桡动脉的SAP测量值高于尾动脉的SAP测量值（平均差值9 mmHg，P < 0.01），但两个方向均出现不一致情况。对于桡动脉（128、129和129 mmHg；P = 0.36）或尾动脉（121、122和122 mmHg；P = 0.82）部位，首次测量值、第2 - 6次测量的平均值或全部6次测量的平均值之间均未观察到差异。在任何一个部位的SAP测量值与年龄、体重、BCS、MCS、焦虑评分或袖带尺寸之间均未发现关联。无论测量部位如何，从适应开始到第一个数据收集系列结束时，心率均显著下降（P < 0.01）。
鉴于与患者变量缺乏关联，初始测量部位可根据患者和操作者的偏好确定，但鉴于不同部位结果不一致，连续的SAP测量应使用相同的部位。
