Continuous Regional Analgesia After Total Knee Arthroplasty

Nantes University Hospital50 enrolled

Overview

This prospective, comparative and double blind study is aimed to determine if normal saline or dextrose 5% in water will modify the stimulation during the insertion of the stimulating catheter used for continuous femoral and sciatic blocks in total knee replacement.

The operator is blinded to the medium fluid to expand the perineural femoral and sciatic nerves before threading in the stimulating catheter. He records all the electric data of electrolocation of nerve, which will be compared to determine whether or not a difference in intensity is found between normal saline or dextrose 5% in water.
