ABSTRACT
Objetive: To compare the clinical efficiency of a local anesthetic drugs combination, against a recent local anesthetic drug alone in the axilary blockage anaesthesia for upper extremity ortopedic surgery procedures. Material and methods: This is a randomized, time-course followed, prospective, blind, and comparative study, in which 60 patients were included. These patients showed E and U, I and II B physical state evaluation according to the ASA score, and they were surgical intervened in upper extremities orthepedic surgery, including the middle and distal region of the limb. Then, the patients were distributed in two groups. Group A: Axilary anaesthesia; group with 400 mg of 1% simple lidocaine, plus 50 mg of 0.5% Bupivacaine in a 40 ml final volume. Group B: Axillary anesthesia with 150 mg of 3.75% Ropivacaine in a unique dose of 40 ml final volume. Premedication was normalized for all patients with 300 mcg/kg of Nalbufine, and 10 mcg/kg of Atropin Sulphate. Population characteristics, latency time, anesthesic time, surgery time, middle blood preassure, heart rate, oxygen saturation, duration and magnitude of motor blockage, and anaesthesia/analgesia quality, were compared. Results: Group A showed shorter latency time than group B 7±3 vs 11±1.5 min. respectively, p‹0.05). Surgery time was 3.40±1.10 hours in group A, and 3.50±1.2 hs. for group B (p›0.05). Analgesia time was 4.45±1.3 hours in group A, and 6.45±1.3 hours for group B, p‹0.05. Motor blockage duration time was compared and we found 3.40±1.4 hs. for group A and 3.10±1.3 hs. 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 those from the comparative groups. There was a sensory appropiate and longer blockage in group B, as well as a shorter motor blockage than group A. One hundred percent of the patients, evaluated the anesthesia/analgesia as excellent in both groups. Conclusions: Both groups entirely comply with the desired objective; nevertheless, Ropivacaine anesthesia resulted in a longer latency and duration, and shorter motor blockage for the patients.REFERENCES
