Which local anesthetic is commonly used in a combination analgesic protocol known as MLK for dogs?
Lidocaine
Why is the use of constant-rate infusion lidocaine during anesthesia not recommended for cats?
It has negative cardiovascular effects
What is the benefit of using lidocaine patches in dogs and cats?
Low systemic absorption rate and high local tissue concentration
What is the recommended application time for eutectic 2.5% lidocaine and 2.5% prilocaine cream for use in dogs, cats, rabbits, horses, and pigs?

Why is bupivacaine liposomal-encapsulated injectable suspension approved for single-dose infiltration into the surgical site?
To release bupivacaine locally due to its small molecule size
Test your knowledge about the use of local and regional analgesic techniques in decreasing intraoperative nociception and postoperative pain. Explore the conduction blockade of nerve fibers by local anesthetics and the related factors such as nerve size, myelination, and activity frequency.
