Abstract
The paper presents a comparative description of the block methods of the brachial plexus in dogs under the control of neurostimulation and sonography. It should be noted that during conduction anesthesia using ultrasound scanning, the problem of constant and long-term visualization of the needle position remains. At the same time, in order to reduce the subjective factor, a method of electrical nerve stimulation was developed, which allows "to find” target nerves by visualizing the motor responses of muscles until the injection of local anesthetics. To confirm the identification of the nerve plexus structures, we used 2 methods: ultrasound leveling for group 1 and double control - ultrasound leveling and electrical stimulation - for the 2nd group. The study involved 28 dogs. The effectiveness of the development of a complete blockade was evaluated based on changes in hemodynamics and respiratory changes in response to a deep pain sensitivity test on each finger of the anesthetized limb. As a result of our study, the double control method showed the most diagnostic accuracy in identifying all the nerve structures of the brachial plexus and amounted to 100 %. In the ultrasound-guided group, the effectiveness of surgical anesthesia was lower and amounted to 86 % for blockade of the brachial plexus by axillary access and 72 % for the paravertebral cervical method.
