[Caudal anesthesia in children].

Caudal block is the most frequently epidural block performed in children. A better knowledge of the child anatomy, physiology and pharmacokinetics has increased the safety of regional anaesthesia in children. The technique of puncture has been adapted to the child anatomy and special needles fit for children are now manufactured. The children, as well as adult, have benefited of new drugs (opioids, alpha 2 agonists) which increase the indications regarding time duration or pain intensity. If complications are still possible the respect of safety rules and the use of adapted equipment make caudal block a safe regional anaesthesia.
