Optimizing Local Anesthetic Concentration for Continuous Lumbar Plexus Nerve Blocks

NCT00912873 Phase 4 COMPLETED Results posted

This is a research study to determine if the concentration of local anesthetic through a catheter next to the nerves that go to the hip that is undergoing surgery, affects muscle strength and sense of touch experienced after surgery. This study is looking at the varying concentrations of local anesthetic placed through the catheter.

Primary outcomes

Percent Change From Baseline in Quadriceps Femoris Maximum Voluntary Isometric Contraction (MVIC) — The study primary endpoint will be the difference in MVIC the morning following surgery compared with the preoperative MVIC, expressed as a percentage of the preoperative MVIC: (preop - postop ) / preop x 100.
Quadriceps femoris muscle strength evaluated using a portable, hand-held, isometric force dynamometer (MicroFET2, Lafayette Instrument Company, Lafayette, IN) to measure the maximum voluntary isometric contraction (MVIC) in a seated position. The study primary endpoint will be the difference in MVIC the morning following surgery compared with the preoperative MVIC, expressed as a percentage of the preoperative MVIC: (preop - postop ) / preop x 100.
