Letter to the editor regarding ‘Modified thoracoabdominal nerve block through perichondrial approach (M-TAPA): an anatomical study evaluating dye spread following simulated injection in soft embalmed Thiel cadaver’

With great interest, we read the original research article by Sawada et al describing valuable local anesthetic diffusion findings using modified thoracoabdominal nerve block through perichondrial approach (M-TAPA).[1][1] During cadaveric dissection, spread of the injectate dye to the intercostal
