The primary aim of this study is to evaluate if multiple postoperative administrations with a solution of ropivacaine, ketorolac and epinephrine into the operating field through a catheter would affect morphine consumption. Secondary end-points are pain intensity, side effects and length of stay.

Condition Intervention Phase
Pain, Postoperative Pain Drug: ropivacaine and ketorolac Drug: Ketorolac Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Local Infiltration Analgesia in Total Hip Arthroplasty - Efficacy of Multiple Bolus Injections With Ropivacaine and Ketorolac

Further study details as provided by University of Aarhus:

Primary Outcome Measures:
  • Morphine consumption [ Time Frame: 24 hours postoperatively ]
    Cummulative morphine comsumption postoperatively

Secondary Outcome Measures:
  • Pain intensity [ Time Frame: 24 hours postoperatively ]
    Pain intensity measured on the visual analog scale (VAS) at rest and during walking

  • Postoperative nausea [ Time Frame: 24 hours postoperatively ]
    Number of episodes of nausea measured on a 3 points rating scale (mild, moderate and severe)

Enrollment: 80
Study Start Date: March 2010
Study Completion Date: September 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: RK-group Drug: ropivacaine and ketorolac
The RK-group receives four intra-articular injections via catheter with a total volume of 40 ml (380 mg ropivacaine and 60 mg ketorolac) combined with 4 intravenous injections of saline during 24 hours postoperatively
Active Comparator: K-group Drug: Ketorolac
The K-group receives four intra-articular injections via catheter with a total volume of 40 ml saline combined with 4 intravenous injections of ketorolac (total 60 mg) during 24 hours postoperatively
