Which block technique allows for intraoperative touch-ups?

• A. Proximal paravertebral block
• B. Distal paravertebral block
• C. Coccygeal block
• D. Intramuscular injection

Answer: (B)

The distal paravertebral block technique is particularly advantageous for allowing intraoperative touch-ups during procedures. This technique targets specific nerves just outside the vertebral column, which innervate the abdominal wall structures of the animal. By delivering local anesthetic in this area, veterinarians can achieve effective analgesia and, crucially, have the flexibility to administer additional anesthetic as needed during surgery.

This is important in surgical settings where patient comfort and precision in pain management are paramount. The ability to perform "touch-ups" allows for real-time adjustments to anesthesia levels, ensuring that the animal remains comfortable and pain-free throughout the procedure. This contrasts with other techniques, which may not offer the same level of adjustability once the anesthetic is administered.
