The Effect of the Minimum Effective Volume for Suprainguinal Fascia Iliaca Block in Fresh Cadavers

The goal of ultrasound-guided suprainguinal fascia iliaca block (USG-SFIB) is anesthetic spread to three nerves, which are lateral femoral cutaneous nerve (LFCN), (FN), and obturator (ON). 90 % minimum effective volume (MEV90) for USG-SFIB each result studied showed the successful effect in various block. So, Thus, study purposes demonstrate efficiency (MEV90,62.5 ml) confirm staining dye connective tissue (nerve layer) that focused on by histological examination cadavers. layer ON epineurium (100 %) un-staining perineurium & endoneurium. Therefore, minimal (MEV) USG-SFIB. Moreover, stain at stained only.
