Background: Arterial blood pressure (BP) monitoring is essential to evaluate cardiovascular performance in clinical practice and during anesthetic procedures in veterinary patients. Measurement of blood pressure can be performed directly (invasively) or indirectly (non invasively). When using non-invasive methods such as the Doppler ultrasonic and oscillometric devices, the accuracy of these methods should be evaluated before they can be used in clinical practice. The present study aimed to determine the agreement between systolic arterial blood pressure (SAP) measured by the Doppler ultrasonic and the Petmap oscillometric device in conscious dogs.Materials, Methods & Results: Thirty one healthy dogs weighing 13.2 ± 4.5 kg were used. The dogs were positioned in lateral recumbency and SAP measurements were performed in the non-dependent thoracic limb. All blood pressure measurements were performed using the blood pressure cuff provided by the manufacturer of the Petmap device. The cuff was positioned proximal to the carpus and its width was approximately 50% of limb circumference. Blood pressure measurements with the Doppler ultrasonic were conducted using a standard technique. A sphygmomanometer was connected to the cuff and the Doppler flow probe was positioned over the common metacarpal artery after the hair was clipped and conductive gel was applied. Three consecutive measurements of SAP were obtained with the Doppler and the mean was used for analysis. Immediately after measurements with the Doppler, the blood pressure cuff was connected to the Petmap, a single automated measurement was obtained and the SAP value was recorded. For each dog, eight pairs of SAP measurements (Doppler measurements followed by the Petmap measurement) were obtained with a minimum of 5-min intervals.[...](AU)
