Thank you for a wonderful educational video Dr Ki-Jinn Chin. I have a question- sometimes I cannot appreciate the musculocutaneous nerve between biceps and coracobrachialis. It’s obvious at times and many times it’s not, what can I do in this situation?
(1) Perform a proximal-distal survey scan back and forth, and look to see a structure sliding towards and away from the artery. (2) occasionally it is impossible to find it, though this is rare in my experience. Inject 10ml or so around the median nerve region, and that should spread to the MCN, as they are often in same compartment. Test the area of interest, e.g. the LACN territory to see if it has been blocked. If not, you can rescue using a LACN block at the antecubital region (see my other video)
