Abstract
In this prospective, double-blinded, randomized, clinical trial, it was evaluated whether paracetamol, as an adjunct to NSAID and opioid analgesia, might limit the requirements for intraoperative fentanyl and postoperative methadone administration in dogs undergoing a singlesite thoracolumbar hemilaminectomy for surgical treatment of an intervertebral disc extrusion. Twelve client-owned dogs were randomly assigned to two multimodal analgesia groups: NSAID + paracetamol group (group NP) and NSAID + placebo group (group N). Intraoperative analgesic assessment was based on the clinical evaluation of a nociceptive response, whereas postoperative analgesic assessment was determined by using the short form of the Glasgow Composite Pain Scale. No statistically significant difference was found in both groups for the intraoperative need for fentanyl (P = 0.18). The probability of having to administer rescue analgesia postoperatively was significantly higher in group N than in group NP (P = 0.01). For both groups, there were no serious side effects reported, nor was any significant difference found between both groups regarding the occurrence of side effects (P = 0.55). Despite multimodal perioperative pain management consisting of a full μ-agonist opioid, a NSAID and paracetamol, intraoperative rescue analgesia was still required, although the need for postoperative opioid based analgesia was significantly lower in group NP.
