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.
