    Epidural local anes: GI effect
    • GI effects of neuraxial anesthesia are largely result of sympathectomy.
    • Abdominal organs derive sympathetic innervation from T6-L2.
    • Blockade of these fibers results in unopposed parasympathetic activity [CN X].
    • Secretions increase, sphincters relax, and the bowel becomes constricted.
    • Nausea is common complication of neuraxial anesthesia.
