Level B

Key Takeaways

Evaluate your patient. Will he be safe if he feels pain or something funny? If he isn’t safe without pain, abort the plan and offer a recumbent castration.

Stay close to the horse and with your handler on the same side

Give your preop medications (NSAID +/- antibiotic) PREOP.

Do not use xylazine alone as your sedation. Xylazine+butorphanol or detomidine +butorphanol would be much safer.

Block the spermatic cords and the skin with lidocaine.

If complications (hemorrhage, evisceration), you will want to lie him down. Be prepared for that possibility.
