Least favorite block and why?

In my heart of hearts I do not have a block I dislike; however with that being said my “least favorite” is the classic approach to the sciatic nerve.  I find this to be a challenging block to perform as finding anatomic landmarks on our ever-changing patient population continues to be more and more difficult and uncomfortable for patients.  I also find this block hard to teach to residents.

Favorite journal Article in the last 2 years:

Desmet M. et al. I.V. and perineural dexamethasone are equivalent in increasing the analgesic duration of a single-shot interscalene block with ropivacaine for shoulder surgery: a prospective, randomized, placebo-controlled study. British Journal of Anaesthesia 2013; 111(3):445-452.

Favorite journal article of all time:

Hebl, James R., et al. “A pre-emptive multimodal pathway featuring peripheral nerve block improves perioperative outcomes after major orthopedic surgery.” Regional anesthesia and pain medicine 33.6 (2008): 510-517.

Favorite (featured) block:

Selective Tibial Nerve Blockade

Why is it your favorite block?

It is the unique anatomic and sonographic features of the sciatic nerve as it branches into the common fibular and tibial nerves in the popliteal fossa that places this block at the top of my favorite list.

3-5 articles about the block?

  1. Sinha, Sanjay K., et al. Femoral nerve block with selective tibial nerve block provides effective analgesia without foot drop after total knee arthroplasty: a prospective, randomized, observer-blinded study. Anesth Analg 115.1 (2012): 202-206.
  2. Buys MJ, et al. Ultrasound-guided sciatic nerve block in the popliteal fossa using a lateral approach: onset time comparing separate tibial and common peroneal nerve injections versus injecting proximal to the bifurcation. Anesth Analg. 2010 Feb 1;110(2):635-7

Pearls, tips, and tricks for success:

Patient comfort, ergonomics and patient positioning. I cannot stress this enough when teaching regional anesthesia.
