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.
