Figure 3

Completeness of sensory block of individual nerves 0–30 minutes after block administration. Completeness of sensory block over time for each major nerve of the upper extremity. (a) Axillary nerve, (b) intercostobrachial and medial brachial cutaneous nerves, (c) medial antebrachial cutaneous nerve, (d) musculocutaneous nerve, (e) median nerve, (f) ulnar nerve, and (g) radial nerve. Supraclavicular block: straight line; infraclavicular block: dashed line; axillary block: dotted line.
