Nerve block

Question 1

What is location of proximal (Cambridge or Farquarson method) paravertebral nerve block?

Answer 1

Just caudal to transverse process of T13, L1 and L2

Question 2

What is the diff. between proximal (cambridge or farquarson) and distal (magda) paravertebral nerve block?

Answer 2

proximal: caudal to transverse process of T13, L1 and L2
distal: above and below the transverse process of L1, L2 and L4

both desensitise the same nerves despite the location because the nerves tend to go caudally after they emerge from spinal foramen
