Continuous Regional Analgesia After Total Knee Arthroplasty
Continuous Regional Analgesia After Total Knee Arthroplasty
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.
