Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Comparison of carprofen and pethidine as postoperative analgesics in the cat.
The postoperative analgesia and sedation in cats given carprofen (4.0 mg/kg bodyweight by subcutaneous injection preoperatively) was compared to that in cats given pethidine (3.3 mg/kg bodyweight by intramuscular injection postoperatively) in a controlled, randomised, blinded, multicentre clinical trial. Further dosing with the particular analgesic was allowed if a cat was exhibiting unacceptable pain. ⋯ In conclusion, carprofen provided as good a level of postoperative analgesia as pethidine, but of a longer duration (at least 24 hours) and was well tolerated. It thus provides an option for 'pre-emptive analgesia' in cats about to undergo surgery.
