David Rosenblum, MD Garden City and Brooklyn Pain Physician, world renown for his work on the PainExam Podcast, PainExam Pain Management Board Review and NRAP Academy’s Continuing Medical Education Programs, discusses: a case of paresthesia in the upper neck realted to C3 and C4 stenosis and considers a selective nerve root block while wondering if a deep cervical plexus block would suffice. Rational : Desire to avoid epidural due to proximity to spinal cord Ultrasound approach of cervial plexus may anesthetize C3 and C4 roots and may be sufficient to do with ultrasound alone Unfortunately, no data found to support this particular situation, however, it may be safe and effective if performed properly.
