Abstract
PICO question
In cats undergoing orchiectomy, does the use of intratesticular lidocaine reduce the pain in patients compared to not using intratesticular lidocaine?
Clinical bottom line
With a low grade of evidence, when compared to a pre-medication with pure-µ agonist opioids, intratesticular lidocaine does not appear to provide significant benefit. However, based on our clinical scenario where pre-medication is with a partial-µ opioid like buprenorphine, there may be benefit in utilising intratesticular lidocaine.
