BackgroundEffective management of postoperative pain leads to increased patient satisfaction, earlier mobilization, reduced hospital stay and costs. One of the methods used for management of postoperative pain is preemptive analgesia-blockade of afferent nerve fibers before a painful stimulus. It modifies peripheral and central nervous system processing of noxious stimuli and reduces postoperative opioid consumption. In this study, we sought to determine whether the preoperative use of pregabalin reduced postoperative pain and morphine consumption in thyroidectomy.Materials And MethodsThe observation was conducted on patients undergoing thyroidectomy surgery in two groups of 30 each. Of the two groups, one received a single oral dose of pregabalin 1 h preoperatively. Both the group of patients undergoes anesthesia in a similar manner. Following surgery the efficacy of the preoperative dose of pregabalin is observed by measuring the total opioid consumption 6 h postoperatively and assessing verbal numeric pain scales.ResultsThe mean time to request of rescue analgesia in pregabalin group was 322.07 ± 69.106 min when compared to morphine group 256.33 ± 111.978 min (P < 0.05). The mean pain scores in the postoperative period were also significantly lower in patients receiving pregabalin.ConclusionSingle oral dose of pregabalin was effective in reducing acute postoperative pain in thyroidectomy patients. It prolongs the time to the request of rescue analgesia and also results in lower postoperative pain scores in the immediate postoperative period. However a statistically significant low opioid consumption could not be proved.
