Spinal Mepivicaine With Fentanyl for Outpatient Knee Arthroscopy

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00803725

Brief Summary:

The purpose of this study is to determine if the addition of intrathecal fentanyl to low dose mepivacaine spinal anesthesia provides adequate surgical anesthesia with shorter duration of motor blockade.

It is hypothesized that lower doses of spinal mepivacaine when combined with fentanyl will result in adequate surgical block for knee arthroscopy surgery with faster recovery and discharge compared to mepivacaine alone.
