Inadvertent epidural anesthesia associated with catheterization following continuous psoas compartment block in a patient with scoliosis

摘要

Rationale:Psoas compartment block (PCB) is typically performed using surface anatomical landmarks and neurostimulation for guidance. However, anatomical anomalies, such as scoliosis, make this technique unreliable, posing a challenge for the anesthesiologist when inducing regional anesthesia.
