Women scheduled for abdominal hysterectomy needs postoperative pain treatment, i.e. morphine. Unfortunately morphine has side-effect: nausea, vomiting, sedation and dizziness, which is unpleasant for the patients and sometimes keeps them at bed longer time than needed. We investigate in new combinations of analgesics for postoperative pain, hoping to minimize the need for morphine.

Primary Outcome Measures:
  • The total amount of morphine needed postoperatively form 0 - 4 h, and 0 - 24 h, administered by the patient controlled pain treatment. (PCA) [ Time Frame: 0 - 24h ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Pain Score (VAS) at rest and at mobilisation. [ Time Frame: 0 - 24h ] [ Designated as safety issue: No ]
  • Postoperative nausea and vomiting. [ Time Frame: 0 - 24h ] [ Designated as safety issue: No ]
  • Sedation. [ Time Frame: 0 - 24h ] [ Designated as safety issue: No ]
  • Dizziness. [ Time Frame: 0 - 24h ] [ Designated as safety issue: No ]
  • All measurements are taken at 2, 4 and 24 h postoperatively. [ Time Frame: 0 - 24h ] [ Designated as safety issue: No ]
