Abstract

This study was conducted in order to evaluate three different non- invasive blood pressure measurement methods (NIBP) in comparison with direct blood pressure measurements in anesthetized dogs. Ten normal healthy Beagle dogs (mean age; 3.7 ± 1.01 yrs, mean body weight 10.2 ± 1.15 kg) were enrolled in this study. BP was measured using three different methods, i.e., Doppler (DOP), oscillometric, and high density oscillometric (HDO) methods, simultaneously, five times in each subject under anesthesia at three different locations (right, left front legs, and tail). The blood pressure value measured by the Doppler method was the closest to the value measured by the direct method. Although the accuracy and consistency of BP measured by three different non-invasive methods differed according to the method, all methods, except the conventional oscillometric method, were acceptable for monitoring systolic blood pressure in anesthetic dogs. The inter-measurement variations in DOP and HDO were minimal without affecting the consistency of the test results.
