Brief Summary:
The purpose of this study is to determine whether general anaesthesia or regional anaesthesia is best for patients undergoing Total Hip Arthroplasty.

Condition or disease Intervention/treatment Phase
Osteoarthritis Drug: GA-arm, remifentanil Drug: RA-arm Not Applicable

Detailed Description:

A randomized controlled trial (RCT) with a follow up time of 48 hrs. Patients scheduled for primary Total Hip Arthroplasty. A total of 120 patients randomly assigned to one of the two alternatives (general anaesthesia (GA) or regional anaesthesia (RA)).

General anaesthesia compared to intrathecal anaesthesia will give shorter length of hospital stay (LOS) for patients undergoing total hip arthroplasty (THA).

Primary endpoint:


Secondary endpoints:

Postoperative pain? Postoperative orthostatic function (dizziness) Time until the patient meets the discharge criteria from PACU How many patients will need at least one urinary bladder catheterisation

Arm Intervention/treatment
Placebo Comparator: RA-arm
RA-arm: the patients in this arm will receive intrathecal anaesthesia consisting of bupivacaine 15 mg
Drug: RA-arm
Intrathecal (i.e. spinal) anesthesia with isobaric bupivacaine 15 mg administered intrathecally at L4-L5.
Other Name: Regional anesthesia

Experimental: GA-arm, remifentanil
GA-arm: patients in this arm will receive general anaesthesia consisting of Target Controlled Infusion (TCI) of remifentanil and propofol
Drug: GA-arm, remifentanil
Remifentanil and propofol will be delivered intravenously via TCI pumps according to the "Marsh" and "Minto" algorithm
Other Name: GA: TCI consisting of remifentanil an propofol

Primary Outcome Measures :
  1. Length of Hospital Stay [ Time Frame: Up to 4 days after surgery ]
    Time from the end of surgery until the patients meets the discharge criteria will be evaluated. Discharge criteria: able to get in and out of bed, Able to get dressed. Able to sit down in a chair and get up again. Able to walk 50 meters wit/without crutches. Able to flex knee 70 degrees. Able to walk stairs. Pain manageable with oral analgesics. Acceptance to be discharged

Secondary Outcome Measures :
  1. Post Operative Pain [ Time Frame: from end of surgey until 48 hrs later ]
    Pain will be monitored using a Visual Analogue Scale. Pain will be monitored with the patient in four different positions. VAS 100 mm used for assessment of pain (0 = no pain, 100 = worst imaginable pain). At each time and position the median VAS-pain score was reported (generally the distribution of pain scores are not normally distributed and hence median value was used)

Other Outcome Measures:
  1. Time Hrs Until the Patient Meets the Discharge Criteria From PACU [ Time Frame: 12 hrs ]
    Hours until the patient meets the discharge criteria from PACU will be monitored every 15 min from teh time the patient arrives to PACU until he/she meets the discharge criteria
