Impact of pregabalin on early phase post-thoracotomy pain compared with epidural analgesia

Background: The purpose of this randomized study was to compare the effects of pregabalin with epidural analgesia on early phase post-thoracotomy pain. Methods: This study was conducted on 90 adult patients who underwent thoracotomy. Patients were randomly divided into two groups, an epidural analgesia group, where 45 patients received 0.2% ropivacaine hydrochloride and fentanyl through a thoracic epidural catheter, and a pregabalin group, where 45 patients received 75 mg pregabalin orally twice daily. Both groups were also administered orally with celecoxib along with each treatment. Numerical rating scale (NRS) and sleep interference rate (SIR) were evaluated on the first day, third day, and fifth day after surgery. Anesthetic induction time, operation time, recovery time, the use of additional analgesic drugs and adverse effects were also examined. Results: NRS and SIR were significantly lower in the pregabalin group at all time points (P Conclusions: Pregabalin is considered to be a safe and effective treatment method which is an alternative to epidural analgesia for acute post-thoracotomy pain.
