PICO question

In dogs undergoing hindlimb orthopaedic surgery does epidural with local anaesthetic and buprenorphine provide equivalent intra- and postoperative analgesia as epidural with local anaesthetic and morphine?


Clinical bottom line

Category of research question


The number and type of study designs reviewed

One double-blinded randomised controlled trial

Strength of evidence


Outcomes reported

Epidural analgesia with buprenorphine and bupivacaine may provide equivalent analgesia to more traditional morphine and bupivacaine epidural injection


There is weak evidence that buprenorphine may provide equivalent analgesia to morphine when combined with bupivacaine epidurally. The reduced regulatory requirements imposed on buprenorphine may sway some clinicians to utilise buprenorphine but further, higher powered, controlled trials are necessary to confirm equivalency


How to apply this evidence in practice

The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.
