(A)Spinal cord 尾端於 L3, 避免 L3 level 以上實施EA,
(B)Delayed myelinization of nerve fibers,onset time is shortened,
(C)Delayed ossification and growth of iliac crests, Tuffier’s line passes over L5-S1 interspace instead of L4-L5 interspace.
(D)Low plasma protein content (HSA and AAG), Increased unbound free fraction of all local anesthetic: greater danger of systemic toxicity
(E)Sympathetic immaturity, fluid preloading and use of vasoactive agents are larger then adult.
