Abstract

Block of brachial plexus is a regional analgesia commonly used for thoracic limb surgery in different animal species. Articaine HCl with epinephrine is indicated for local infiltrative anesthesia in both simple and complex dental procedures in humans. This study aimed to evaluate the effectiveness of articaine HCl with epinephrine for brachial plexus blockage in goats, using ultrasonography for guidance. The study involved two cadavers for anatomical exploration of the brachial plexus, as well as 18 adult goats of both sexes. A 7.5-9 MHz micro-convex transducer was employed to visualize the brachial plexus and guide the sterile needle to inject 4% articaine HCl with epinephrine. The used dose was 0.25 mL kg^-1 (10mg/kg). The beginning and length of both motor and sensory impairments were registered following the injection. The results showed the onset times for motor and sensory blocks were 1.4 ± 0.45 min and 2 ± 0.41 min, respectively. The duration of motor and sensory blocks was 186.4 ± 13 min, and 176.4 ± 13 min, respectively. Importantly, the brachial plexus block was not associated with any catastrophic vascular injection, seizures, and paresthesia. Based on the findings of this study, it can be concluded that 4% articaine HCl with epinephrine is effective for brachial plexus blockage, especially when guided by ultrasonography.
