NCT00968955
First received: August 28, 2009
Last updated: September 28, 2011
Last verified: September 2011
  Purpose

The purpose of the study is to compare the effects of per-operative local infiltration analgesia with ropivacaine 0,2 % (150 ML) versus placebo on acute postoperative pain intensity after total hip arthroplasty.

The hypothesis is that local infiltration analgesia reduces the acute postoperative pain intensity.

Primary Outcome Measures:
  • Postoperative pain scores on the Visual Analog Scale (during walking) [ Time Frame: up to 8 hours ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Additional analgetics measured as cumulated amount i mg [ Time Frame: up to 8 hours ] [ Designated as safety issue: No ]
  • Time spend in hospital measured as nights after surgery [ Time Frame: At discharge (mean 2-3 nights) ] [ Designated as safety issue: No ]
  • Number of Participants with Adverse Events as a Measure of Safety and Tolerability [ Time Frame: up to 8 hours ] [ Designated as safety issue: Yes ]
  • Postoperative pain scores on the Visual Analog Scale (at rest) [ Time Frame: up to 8 hour ] [ Designated as safety issue: No ]

Detailed Description:

In spite of being one of the last century's most successful surgical procedures in treatment of advanced osteoarthritis total hip arthroplasty is still associated with postoperative pain and delayed rehabilitation. We therefore decided to evaluate the effects of per-operative local infiltration analgesia with ropivacaine 0,2 % (150 ML) versus placebo on acute postoperative pain intensity in a well defined, multimodal, fast-track setup after hip arthroplasty. The technique is widely used as standard treatment in many European centers despite its limited evidence.
