Postoperative pain is usually treated with opioids. Among them, oxycodone is popular in the daily practice as it is administered orally and is easily titrated. However, side-effects include increase duration and frequency of apneic episodes. Some authors believe that tramadol has less impact on these apneic episodes during the first postoperative night, based on a trial that reported conclusive results only during the first 2 postoperative hours. The objective of this randomized controlled trial is to compare the effect of postoperative pain treatment of oxycodone with tramadol on apneic episodes during the first and third postoperative nights.
