RESUMO
We prospectively evaluated the feasibility and efficacy of a simple method for inserting 5.1-cm brachial plexus catheters using a fascial click technique. In 120 patients, after inserting an axillary catheter by a resident and verifying adequate position using a nerve stimulator, 0.7 mL/kg 1% mepivacaine was injected. Success of blockade (analgesia at 40 min in the 4 terminal nerves), analgesia efficacy, and resident autonomy were recorded. The primary success rate was 87%. Reinjections were performed preoperatively and perioperatively in 40% and 50% of patients, respectively. The resident completed the technique in 91% of cases. We conclude that this technique is easily performed by residents in training and is associated with frequent success for anesthesia and postoperative analgesia.
