Infraclavicular @entity616 has recently become a technique of increasing interest. However, no approach has provided easily identifiable landmarks, good conditions for catheter placement, and lack of complications (mainly pneumothorax). We describe a modified approach of the Raj technique based on the identification of the anterior acromial process, jugular notch, and emergence of the axillary artery within the axillary fossa, with the arm abducted to 90 degrees and elevated by approximately 30 degrees. We evaluated the clinical characteristics of this approach by injecting 40 to 50 mL of @entity1342 0.6% in 150 @entity1 scheduled for elective surgery of the forearm, wrist, or hand. Success was defined as a sensory block of the 5 nerves with territories distal to the elbow within 30 min after performing the block. The success rate was 97% when a distal response (flexion or extension of the wrist or fingers) was elicited and 44% when a proximal (contraction of the triceps, biceps) was obtained using a nerve stimulator. Complications were rare: aspiration of blood was seen in 2% of @entity1 and @entity1410 was seen at the puncture site in 0.6%; no pneumothorax occurred. Eleven @entity1 (7%) complained of some @entity158 during the procedure. We conclude that the modified approach of the Raj technique for @entity616 is very effective when a distal nerve stimulator response is obtained with a small complication rate and a high degree of @entity1 satisfaction. IMPLICATIONS: We describe a modified approach of the Raj technique for the infraclavicular brachial plexus. The elicitation of a distal nerve stimulator response is associated with a high success rate, a low incidence of complications and a high degree of @entity1 satisfaction.
