Comparison of Epidural Oxycodone and Epidural Morphine

The primary objectives of this study are to compare the efficacy of pain relief between epidural oxycodone and epidural morphine for postoperative analgesia after elective caesarean section and to compare the incidence and severity of pruritus. Secondary objectives are to compare other side effects of epidural administered oxycodone and morphine (nausea and vomiting, sedation, respiratory depression) and to investigate the safety and efficacy of epidural oxycodone and epidural morphine after use for postoperative analgesia in caesarean sections.
