Caudal loco regional anesthesia is a quite simple and secure procedure. That is a prospective study made on seventy children operated in orthopaedics, urology and general surgery below the ombilicus. The caudal epidural anesthesia followed a general anesthesia in all seventy cases and brought relief in terms of analgesia, even for those painful surgical procedures. The good post operative status with only some minor complications leads us to use widespreadly caudal epidural.
