- Primary Outcome Measures
Name Time Method It is expected to find the lowest effective dose of the local anesthetic ropivacaine in the saphenous blockade guided by ultrasound using the up and down method of Dixon. In this method the previous patient is control of the next patient. Diffused and accepted method for effective dose calculations. Analgesia will be verified by the visual analgesic scale and analgesic consumption in the postoperative period and the motor block will be evaluated by the Bromage scale and the use of the force dynamometer. Thus it is expected to find the minim dose that does not promote motor blockade and that allows the patient to go to hospital on the same day, without pain and without motor block.
