Ultrasound-Guided Infraclavicular Brachial Plexus Block: Prospective Randomized Comparison of the Lateral Sagittal and Costoclavicular Approach

Background and Objectives It has recently been proposed that an infraclavicular brachial plexus block (BPB) at the costoclavicular (CC) space may overcome some of the limitations of the lateral sagittal (LS) approach. In this study, we hypothesized that the CC approach will produce faster onset of sensory blockade of the 4 major terminal nerves of the brachial plexus than the LS approach. Methods Forty patients undergoing elective upper extremity surgery under a BPB were randomized to receive either the LS (Gp-LS, n = 20) or CC approach (Gp-CC, n = 20) for infraclavicular BPB. Twenty-five milliliters of 0.5% ropivacaine was used for the BPB in both study groups. Sensory-motor blockade of the ipsilateral median, radial, ulnar, and musculocutaneous nerves was assessed by a blinded observer at regular intervals for 45 minutes after the block. Sensory block was assessed using a verbal rating scale (0–100) and motor block using a 3-point qualitative scale (0–2). Onset of sensory (primary outcome variable) and motor blockade was defined as the time it took to achieve a sensory verbal rating scale of 30 or less and motor grade of 1 or less, respectively. Time to readiness for surgery was defined as the time it took to achieve a sensory score of 30 or less and motor grade of 1 or less in all the 4 nerves tested. Results The overall sensory onset time (median [interquartile range]) was significantly faster (P = 0.004) in Gp-CC (10 [10–26.25] minutes) than in Gp-LS (20 [15–30] minutes). The overall sensory score was significantly lower in Gp-CC than in Gp-LS at 5 (P
