Continuous lumbar paravertebral block

This is a text tutorial that discusses the nerve stimulator-guided continuous lumbar plexus block. It is also known as the psoas compartment block or the lumbar paravertebral block. There is zero or almost zero good indica block. There is zero or almost zero good indicationtions for performing a single-injection lumbar plaxus block. And, if we do, we still have to use a Tuohy needle, because, like for all paravertebral blocks, the spinal roots are surrounded with dura and arachnoid maters.

Continuous femoral nerve block

This is a text tutorial that discusses the nerve stimulator-guided single-injection femoral nerve block. It deals with the applied anatomy and the technique in great detail. Like all other continuous nerve blocks, secondary block failure is a huge problem if the catheter is not placed in the correct perineural compartment (see the microanatomy section for detail). Experience has taught us that needle placement with ultrasound and then catheter placement with nerve stimulator guidance provides the best of both worlds and…

Single-injection Infraclavicular block

This is a text tutorial that discusses the nerve stimulator-guided single-injection and continuous infraclavicular block. It deals with the applied anatomy and the technique in great detail. This is a very successful block, but the continuous infraclavicular has to be done as described here aiming the needle toward the proximal parts of the cords where they are all together in the same circumneurium and before they split off to arrange around the axillary artery to form three separate cords. The…

Continuous cervical paravertebral block

This is a text tutorial that discusses the nerve stimulator-guided continuous cervical paravertebral block. It deals with the applied anatomy and the technique in great detail. The single-injection version of this and all other paravertebral blocks is identical, but a bolus of the local anesthetic agent is injected through the needle, and a catheter is not placed. Exactly the same equipment (large bore Tuohy needles) and approach should be needed. Like all other continuous nerve blocks, secondary block failure is…

Continuous axillary block

This is a text tutorial that discusses the nerve stimulator-guided continuous axillary block. It deals with the applied anatomy and the technique in great detail. Because al the nerves at this level are in their own circumneural sheath, this block is falling out of favor, because the continuous infraclavicular nerve block (below) is a better choice and the continuous axillary block has a high rate of secondary block failure because the nerves are all separate entities at this level, and…
