Summary
Caudal block is often performed to relieve postoperative pain in pediatric urological
surgery. Recently, pudendal block is also used in penile surgery and it has advantage because
of less side effects such as transient weakness of low extremities, but limited to use in
penile surgery. Local anesthesia is a single shot injection, so additional analgesic drugs is
required when the effect of local anesthetics are disappeared. Dexmedetomidine, an alpha
adrenergic agonist, is commonly used in pediatric sedation. It has analgesic effect and
potentiates the effect of local anesthetics. There are many studies about the potentiation of
the effect of local anesthetics when added to dexmedetomidine in adults, it has been limited
in pediatrics. Recent study said that local anesthetics with dexmedetomidine had prolonged
duration of analgesia in caudal block, also in ilioinguinal block. Thus it is expected to
have a prolonged effect when investigators use dexmedetomidine in pediatrics as well as
adults.
