The use of tunnelling for caudal catheter insertion minimizes the complications associated with opioids and other sedative medications required for adequate patient immobilization, reducing the risk of apnoea and allowing adequate analgesia for more than 3 weeks with a lower risk of insertion site infection.
The use of caudal catheters allows the epidural administration of local anaesthetic dilutions with adequate pain control, but the risk of infection is significantly increased because of proximity of the insertion site to the perineum.
