 The investigator who testing the block is dont know the dose. Sensory block was evaluated for each nerve distribution using ice to test cold sensation, comparing the anaesthetized arm with the contralateral arm, and graded on a three-point scale 0, no difference between sides; 1, some difference between arms but cold still sensed in the blocked arm; 2, no cold sensation in the blocked arm. Motor block for each nerve was evaluated by asking the patient to extend the flexed arm and wrist radial nerve, flex the wrist and oppose the second and third fingers and thumb median nerve, flex and oppose fifth finger towards the thumb ulnar nerve and was graded as 0, no change; 1, reduced contraction; 2, no contraction. Data were collected every 5 min for the first 60 min, and then 1,2,4,6,8,10,12,18,24 hours. motor and sensory scale, the total value should be higher than 10, if not surgical anesthesia was considered unsuccessful. sensitive block score must be at least five. VAS determination was performed with a scale of numbers between 0 and 10 cm. 1mgkg tramadol and 15 mgkg paracetamol IV infusion were administered to patients with a reequirement for additional analgesia VAS 4 . The total number of patients who required additional analgesic drugs was noted. During the initial procedures, the operation and postoperatively, patient satisfaction was evaluated as poor 1, moderate 2, good 3 or very good 4.
