Patients scheduled for primary total hip replacement needs postoperative pain treatment: i.e. morphine. Unfortunately morphine has side-effects: 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 and improve the patients pain score after operation.

Further study details as provided by Glostrup University Hospital, Copenhagen:

Primary Outcome Measures:
  • The total amount of morphine needed postoperatively from 0-4 h, and 0-24 h, administered by a patient controlled pain treatment. (PCA)

Secondary Outcome Measures:
  • Pain score (VAS) at rest and at mobilisation.
  • Postoperative nausea and vomiting.
  • Sedation.
  • Dizziness
  • All measurements are taken at 2,4 and 24 h postoperatively

Estimated Enrollment: 120
Study Start Date: October 2005
Study Completion Date: June 2007
Detailed Description:
We investigate the effect of paracetamol versus paracetamol + pregabalin versus paracetamol + pregabalin + dexamethasone on pain and morphine usage in the first 24 hours postoperatively in patients getting a new hip alloplastic.
