BADEMCI, G. et al. Can facet joint infiltrative analgesia reduce postoperative pain in degenerative lumbar disc surgery?. Neurocirugía [online]. 2008, vol.19, n.1, pp.45-49. ISSN 1130-1473.

Objective. Perioperative analgesia effects the postoperative course of pain. The purpose of this study was to evaluate its possible relation with the consumption of dolantine and analgesics and the facet-induced pain and postoperative pain score in degenerative disc surgery. Methods. We employed perioperative intra- and perifacet bupivacaine infiltration technique to reduce the postoperative pain after lumbar disc surgery. The study was randomized and observer blinded enrolling 40 American Society of Anesthesiologists physical status class I-II patients scheduled for elective degenerative lumbar disc surgery. The patients were divided into two groups of 20 of which Group 1 underwent injection of bupivacaine into the subcutaneous and muscular layers around the incision site, while Group 2 underwent additional intra- and perifacetal joint infiltration. Postoperatively, the patients were provided with a programmed patient-controlled pump which was only activated on demand to infuse dolantine for the next 24 hours. In the postanesthesia care unit the delay for analgesia and the dose of dolantine used were recorded. Results. There was no statistical significance between these two groups regarding postoperative visual analoque scale scores. The time before the first analgesic request was significantly longer in facet group (p= 0,006). The cumulative dolantine dose was also significantly lower in the facet group (p= 0,001) Conclusion. The results indicate that facet joint infiltrative analgesia may have an effect on the postoperative analgesic requirement and reduce the dolantine consumption.
