Comparison of Ultrasound Guided Saphenous Nerve Block using Two Different Anatomical Approaches in patients undergoing knee surgery

The present study was designed to compare and evaluate to applicable the ultrasound guided saphenous nerve blocks which are supsartorial approach and medial condyl approach, and measure to onset time, block duration time, patient satisfaction. Sixty patients between 18 to 60 years of age undergoing sub-knee surgery were randomized to two groups. Intervention(s): Saphenous nerve block performs using the ultrasound-guided technique with 5 mL 0.25 % levobupivacaine+ %1 lidocaine with either subsartorial tecnique or medial condyl tecnique. Main outcome measures: Blocks duration time, block onset time and patient satisfaction over the course of 24 hours.
