Could Peri-anal Block be Effective as Caudal Block in Trans-anal Pull-through Surgery for Children With Hirschsprung Disease??. A Randomized Controlled Trial.

Caudal anesthesia is one of the most commonly used regional anesthetic and analgesic technique in pediatric patient as it is an easy safe and reliable method that can be performed for both intraoperative and postoperative analgesia in patient undergoing lower abdominal and lower limb surgery. It can be used for upper abdominal surgery by increasing the volume of local anesthetic injected or through advancing a catheter.

Caudal anesthesia is a common practice given along with general anesthesia to decrease intraoperative inhalational anesthesia requirements, postoperative pain and emergence agitation.

So many patients are complaining from ano-rectal pathologies, these diseases are common in both sexes and all age groups. The spectrum of anorectal disorders ranges from benign and irritating (pruritus- ani) to potentially life-threatening (anorectal cancer) and the surgical intervention is performed mostly under general or regional anesthesia.

While general and regional anesthetics provide reliable anesthesia, they are often associated with nausea,vomiting, urinary retention and motor blockade of lower limbs. Moreover, repeated spinal or epidural punctures performed by inexperienced anesthesiologists often cause delays in the tight schedule of operations.

Several reports have described various forms of local anesthetic infiltration for ano- rectal surgery , hemorrhoidectomy,anal fistula or fissure surgeries or lateral sphincterotomy. Local peri-anal infiltration is a simple procedure that can be easily learned and performed by surgeon and this method allows the operation to begin almost immediately.
