PICO questionIn cats undergoing orchiectomy, does the use of intratesticular lidocaine reduce the pain in patients compared to not using intratesticular lidocaine?Clinical bottom lineWith 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. <img src="https://www.veterinaryevidence.org/rcvskmod/icons/pr-icon.jpg" alt="Peer Reviewed" /
