ABSTRACT

Background: To compare the clinical efficiency of local anesthesics in Supraclavicular blokade, for upper extremity surgical procedures. Material and methods: Randomized, time-course followed, prospective, and comparative study, in which 60 patients were included. These patients showed E and U, I and II B physical evaluation of the A.S.A. classification scale, and were scheduled for surgery of upper extremities. The patients were distributed in two groups. Group A: Supraclavicular anesthesia, with lidocaine 1% simple 400 mg., plus bupivacaine 0.5%, 50 mg. for 40 ml volume. Group B: Supraclavicular anesthesia with Ropivacaine 0.75%, 150 mg, unique dose in 40 ml. of volumen. Same preanesthetic medication was administered for all patients with Nalbuphine 300 mcg/kg and Atropine 10 mcg/Kg. Population characteristics, latency time, anesthesic time, surgery time, mean blood pressure, heart rate, oxygen saturation, duration and magnitude of motor block and anesthesia/analgesia quality were compared. Results: Group A showed the shortest latency time 5 ± 2 minutes, group B 8 ± 1.5 min. Surgery time was 3.20± 1.20 hours in group A, and 3.40±1.3 hs. for group B. Analgesia time was 5.50±1.6 hours in group A, and 6.20±1.2 hours for group B, p‹0.05. During surgery and in the postoperative period, hemodynamic variables did not show any statistically significative difference between patients from the same group, and in different groups. We observed adequate senstive block and also longer in B; the motor block was shorter in B. In one hundred percent of the patients evaluated, the anesthesia/analgesia was excellent. Discusion: The two groups approaches for the brachial plexus block are safe and efficient; nevertheless, ropivacain anesthesia resulted in a longer latency, duration, and less motor blockade for the patients.
