External Oblique Intercostal Block - Anatomical Principles [Nov 2023]

This is a brief overview of the anatomical principles underlying the external oblique intercostal (EOI) block, which is a relatively novel technique proposed for upper abdominal analgesia.

I accidentally discovered this technique many years ago while attempting to perform deep serratus plane blocks for rib fractures. Early on, I did not always appreciate the difference in thickness of the EO and serratus anterior and sometimes deposited LA under the EO...but, fortunately, I found that both techniques were successful! Glad that Hesham got this published!

Thanks for this..
Wish to see the block you give, your tips and tricks.
