98 pediatric patients aged 6months to 12years who underwent caudal levobupivacaine for hypospadias surgery were evaluated retrospectively.Patients with intravenous morphine added group 1; patients with intravenous clonidine added group 2, caudal morphine added group 3, and caudal clonidine added group 4patients. When the CHEOPS pain scores of 6 or higher were assessed according to the groups at the 1st hour, there were 8 cases in the intravenous morphine group(40%), 5cases in the intravenous clonidine group (25%), and 3 cases in the caudal morphine group (15%).When the CHEOPS pain scores of 6 or higher were assessed according to the groups at the 12th hour, there were 5cases in the intravenous morphine group(25%), 10cases in the intravenous clonidine group (50%), and 4 cases in the caudal morphine group(20%).When the CHEOPS pain scores of 6 or higher were assessed according to the groups at the 24th hour, there were 10 cases in the intravenous morphine group(50%), 10cases in the intravenous clonidine group (50%), 9 cases in the caudal morphine group(45%) and 2 cases in the caudal clonidine group (10%) (p0.05). The lowest pain scores at the 1st, 12th, and 24th hours were recorded in the caudal clonidine group.It has the lowest, best pain scores at 6hours.By these methods, in favor of the clonidine group, we agreed that the analgesia lasts for 12 hours postoperatively, so the postoperative stress that the children and their families have can be minimized.
