[Effect of small-doses ketamine on postoperative pain management with combinations morphine/ketoprofen or lidol/ketoprofen after major gynecological surgery] [corrected].

: We examine the potential beneficial effect of small-doses ketamine on postoperative pain management with combinations morphine/ketoprofen or lidol/ketoprofen after major gynecological surgery. After patient written consent, 50 healthy women, which were scheduled for abdominal gynecological surgery were randomly allocated into two groups depending of postoperative analgesic technique--morphine/ ketoprofen or lidol/ketoprofen. The quality of postoperative analgesia, total opioid consumption for the first postoperative day and unwished side effects were assessed. Demographic and surgical data were identical in the groups. Using ketamine during the anesthesia improve quality of postoperative analgesia in accordance with less opioid consumption for the combination morphine/ ketoprofen, but not for the combination lidol/ketoprofen. Adding small doses ketamine to combination morphine/ketoprofen improve postoperative analgesia; reduce morphine consumption and incidences of morphine-related side effects after major gynecological surgery.
