Blood Levels of Local Anaesthetic in Knee Arthroplasty

• Status: Completed
• Trial end date: 2013-01-01
• Target enrollment: 0
• Participant gender: All

Summary

The primary goal is to evaluate ropivacaine blood concentrations during and after local anaesthetic (ropivacaine) infiltration - the Caledonian technique - for total knee replacement surgery. The investigators plan to measure these levels by testing blood samples taken over a timed period.

This will allow us to confirm whether the current regimen of local anaesthetic use is within safe limits.
