Often patients undergo procedural sedation in order to achieve adequate pain control and muscle relaxation. Alternatively or adjunctively, you can inject the shoulder joint with an anesthetic. Personally, I have had variable effectiveness with this technique. In cases of inadequate pain control, I always wonder if I was actually in the joint. How can you improve your success rate in injecting into glenohumeral joint injection? Trick of the trade: Ultrasound guided shoulder injection I found a great video on this technique, which is essentially a hematoma block in the joint. This screencasted talk is by Dr. Mike Stone (Highland Hospital) as part of his 2011 ACEP Scientific Assembly lecture on nerve blocks. Coincidentally, I ran into Mike at this week's UCSF Topics in Emergency Medicine course where he gave a talk on the use of ultrasound for the hypotensive patient. When I mentioned that I was going to highlight his shoulder injection trick on this blog, he whipped out his laptop and gave me the 6 minute portion of his ACEP talk. Wow, that was really nice of him. To view his entire video on nerve blocks, check out the video here . Things I learned about injecting the shoulder 1. Use a spinal needle. A traditional needle often will not reach the glenohumeral joint. 2. You almost always get a flash of blood (hemarthrosis) when you are in the joint. Also check out Dr. Stone's great ultrasound website called Point of Care http://pointofcare.blogspot.com/ I'm a fan. |

Who loves relocating shoulder dislocations as much as I do?
