PEC 1 & 2 Blocks, Serratus Anterior Block

I’ve been hearing more and more about PEC 2 block for mastectomy.  What’s wonderful about this block is that it seems that the risk of pneumothorax is lower than for a paravertebral block.

  • U/S guidance: probe position similar to infraclavicular block. Find 3rd, 4th rib.
  • Pt position: Head away from side of block. Ipsilateral arm abducted.
  • PEC 2: Inject 20 ml 0.25% bupi between pec minor and serratus.
  • PEC 1: Inject 10 ml 0.25% bupi between pec major and pec minor.
  • Serratus: 5th rib, mid-axillary line. Inject 30 ml 0.125% bupi along top (superficial) and bottom (deep) of serratus muscle (which is just deep to the latissmus dorsi).

Paravertebral Block: basics and cancer recurrence

 

From J Anaesthesiol Clin Pharmacol. 2011 Jan-Mar; 27(1): 5–11.
Why do paravertebral blocks?

From NYSORA

But wait… what about the potential side effects/adverse events from a paravertebral block?

Why not do a TIVA with propofol and dexmetetomedine and local anesthesia via surgeon?  Where’s that study to compare?

** Update **  July 20, 2016 –> What about the PEC 1&2 Blocks as well as Serratus block?
