Arms Assigned Interventions
Active Comparator: A Drug: Epidural Ropivacaine, morphine
Infusion rate 4 ml/h in 48 h Solution 200 ml Ropivacaine 2mg/ml added 1 ml morphine 10 mg/ml
Experimental: B Drug: Ropivacaine, Ketorolac and Adrenaline
Wound infiltration: 100 ml Ropivacaine 2 mg/ml added 1 ml Ketorolac 30 mg/ml and 0,5 ml adrenaline 1 mg/ml Bolus injection: 20 ml Ropivacaine 7,5mg/ml added 1 ml Ketorolac 30 mg/ml and 0,5 ml adrenaline 1 mg/ml

Detailed Description:

Sufficient postoperative pain relief after total hip replacement is necessary to achieve normal mobilisation and a reduction of the surgical stress response. After total hip replacement epidural treatment has proven superior, with regards to pain relief, than treatment with parenteral infusions and periphery nerve blocks. Even though epidural treatment gives excellent pain relief adverse effect as motor block, urine retention, hypotension and itching occurs regularly which delays rehabilitation.

Treatment with the administration of local anesthetic in the operating field has shown its efficiency in reducing postoperative pain with a low incidence of adverse effects after various surgical procedures.

This study compares continuous epidural infusion of ropivacaine added morphine to a new technique, where ropivacaine, ketorolac and adrenaline is used to infiltrate the tissue around the hip joint during surgery, and is injected by an intraarticular catheter 8 hours postoperative.

Data of pain scores, analgesia consumption, adverse effects and mobilisation is collected for the first 4 postoperative days.
