Can Caudal Dexmedetomidine Provide Effective Analgesia?

The goal of this clinical trial is to evaluate if caudal dexmedetomidine can provide effective analgesia during inguinoscrotal surgeries in pediatrics, if used caudally alone (and not as an adjunct to caudal bupivacaine). The main question it aims to answer is: * Can caudal dexmedetomidine provide effective analgesia? Participants will be pediatrics aged from 1 to 6 years ASA-I and ASA-II undergoing inguinoscrotal surgeries. - A total of 50 pediatric patients who will undergo inguinoscrotal surgery will be allocated randomly into 2 equal groups: * Group B (n =25): In this group, and after induction of general anesthesia, pediatric patients will receive a caudal injection of bupivacaine 0.125 % in a dose of 1ml/kg. * Group D (n =25): In this group, and after injection of general anesthesia, pediatric patients will receive a caudal injection of dexmedetomidine in a dose of 1.5 mcg/kg.
