Comparison of Efficacy of Oral versus Regional Clonidine for Postoperative Analgesia following Ilioinguinal/iliohypogastric Block in Children: A Prospective, Randomized, Double-blinded, Placebo-controlled Study.

Both oral and regional clonidine was equally efficacious in prolongation of duration and quality of analgesia. Oral clonidine produces better preoperative sedation and parenteral separation which is an added advantage in pediatric population.
