Effect of Hip/Shoulder-Width Ratio on Sensory Blockade After Intrathecal Anesthesia for Adult Subumblical Herniorraphy

November 9, 2024 updated by: Amr Abdelazeem Fouad, Assiut University

Spinal anesthesia is a straightforward and reliable technique frequently employed in lower body surgeries, achieving adequate surgical conditions through the injection of a small amount of local anesthetic (LA) into the intrathecal space . One advantage of spinal anesthesia over general anesthesia is reduced exposure to potentially depressant drugs .
