UnlabelledThe results of 1133 axillary catheter brachial blocks are reported. Effectiveness and side-effects were monitored in a prospective manner over a period of 1 year.MethodThe puncture was performed with an 18-gauge plastic cannula fitted with a solid steel stylet. The stylet has a 45 degrees, short bevel with rounded edges. When puncturing the axillary neurovascular sheath, no attempt was made to elicit paresthesias with the needle. A distinct "click" and very easy advancement of the plastic cannula were signs of being well inside the neurovascular sheath. To confirm the correct positioning, 0.5-3 ml refrigerated saline solution were injected. If no paresthesias could be produced, a new puncture was performed using a nerve stimulator. The plastic cannula was fixed to the skin. For long-lasting operations or if postoperative analgesia or sympatholysis was required, a more flexible catheter was introduced through the plastic cannula. As an initial dose 40 ml 1% mepivacaine was injected via the cannula. If there was an insufficient block after 20 min, another 20 ml 1% mepivacaine was given. For long-lasting operations, 40 ml 1% mepivacaine was injected every 2 h.ResultsSurgery was completed in 72% of patients; 24% required some form of supplementation including 17.2% of patients who received a "top-up" after 20 min (Table 1). In 3.8% of cases the technique was considered to be a complete failure, meaning that patients needed some type of general anesthesia including the use of i.v. ketamine.(ABSTRACT TRUNCATED AT 250 WORDS)
