The effect of preemptive use of pregabalin on postoperative morphine consumption and analgesia levels after laparoscopic colorectal surgery: a controlled randomized trial.

Abstract

In order to reduce postoperative opioid administration and pain levels in patients submitted to laparoscopic colectomy, we assessed the efficacy of preemptive use of pregabalin (PG), as part of a multimodal analgesia scheme, in a randomized controlled trial setting. Overall, fifty adult patients scheduled for elective laparoscopic colectomy were included and randomized in our trial. In the experimental group, 23 patients received preoperatively 2 doses of 150mg PG per os, whereas the control group consisted of 27 cases, where a matching to PG placebo was administered at the same scheme. The two groups had identical analgesia and anesthesia regimens otherwise. Our study endpoints included postoperative morphine consumption, postoperative pain, and complication rates. Patients in the PG group displayed a significantly reduced morphine consumption at 8h, 24h, and 48h postoperatively. The two groups were comparable in terms of postoperative pain (rest and movement assessment) and side effects. The preoperative addition of PG resulted in a significant reduction of the postoperative opioid consumption in patients undergoing laparoscopic colectomy. However, an association with the postoperative pain scores was not identified.
