Objective

To evaluate a veterinary-specific oscillometric noninvasive blood pressure (NIBP) system according to the guidelines of the American College of Veterinary Internal Medicine (ACVIM) Consensus Statement.

Study design

Prospective clinical study.

Animals

A total of 33 client-owned cats (20 females and 13 males).

Methods

Cats were premedicated with methadone (0.3 mg kg⁻¹) and alfaxalone (2 mg kg⁻¹) intramuscularly. After 15 minutes anesthesia was induced with isoflurane (3%) in 100% oxygen by facemask while breathing spontaneously. A 22 gauge catheter was placed in the median caudal artery and systolic (SAP), diastolic (DAP) and mean (MAP) arterial pressures were measured. NIBP measurements were collected by placing the cuff (40% of limb circumference) on the right or left antebrachium. The agreement between the two methods was evaluated with the Bland–Altman methods, and the oscillometric NIBP device was evaluated using the ACVIM guidelines for validation of devices.

Results

Data from 30 of the 33 cats were analyzed. Five paired measurements were taken from each cat, totaling 150 paired measurements. Mean bias (limits of agreements) for SAP, DAP and MAP were 2.7 (−22.7 to 28.1), 0.9 (−22.3 to 24.2) and 1.3 (−20.4 to 23.0). The oscillometric NIBP passed all validation criteria, except correlation which was <0.9 for SAP, DAP and MAP.

Conclusions and clinical relevance

The Vet20 did not meet all validation criteria by the ACVIM. However, all criteria except correlation were met.

示波血压监测仪Vet20 SunTech在麻醉的健康猫中的验证。

目的

根据美国兽医内部医学学院（ACVIM）共识声明的指南，评估兽医专用示波无创血压（NIBP）系统。

学习规划

前瞻性临床研究。

动物

共有33只客户拥有的猫（雌性20只，雄性13只）。

方法

用肌内注射美沙酮（0.3 mg kg ^-1）和阿法沙酮（2 mg kg ^-1）对猫进行药物治疗。15分钟后，在自发呼吸的同时，通过面罩用100％氧气中的异氟烷（3％）诱导麻醉。将22号导管放置在尾动脉正中，并测量收缩压（SAP），舒张压（DAP）和平均（MAP）动脉压。通过将袖带（四肢围度的40％）放在右或左前臂上来收集NIBP测量值。两种方法之间的一致性使用Bland–Altman方法进行了评估，而示波NIBP设备则使用ACVIM指南对设备进行了评估。

结果

分析了33只猫中30只的数据。从每只猫进行五次配对测量，总共进行150次配对测量。SAP，DAP和MAP的平均偏差（协议限制）为2.7（-22.7至28.1），0.9（-22.3至24.2）和1.3（-20.4至23.0）。示波法NIBP通过了所有验证标准，但相关性对于SAP，DAP和MAP而言<0.9。

结论与临床意义

Vet20不符合ACVIM的所有验证标准。但是，除相关性外，所有标准均已满足。
