I was just wondering how many people have had a scalene block specifically testing for scalene nerve/vascular compression? If you have, where did you have it done and what technique was used?

The reason I'm wondering about this is because my local pain medicine anesthesiologist thinks that a scalene block means numbing the entire arm as though for shoulder surgery. Apparently there must be at least two types of scalene blocks...one that relaxes the muscle and another that numbs the brachial plexus. I would really like to find someone that performs the former, either in Minnesota or elsewhere, as I'm sure others would, too. Are only the top TOS docs doing these types of blocks????
