Background: Caudal block is recommended for analgesia during and after hypospadias repair operation of the penis in children. Aim of work: Compare the effectiveness of caudal block vs. dorsal penile block in children undergoing hypospadias repair surgery with respect to postoperative analgesia and appeal for rescue analgesics during the first 24 hours. Patient and Methods: The study was conducted on 40 male children, ASA I-II, 4-8 years of age undergoing hypospadias repair surgery under general anesthesia. Children were randomly classified into two groups: (Group P) (penile group=20 patients) received a penile block of 2mL bupivacaine 0.25 per cent on each side, (Group C) (caudal block group=20 patients) with a caudal block of 0.25 per cent (1mg / kg) bupivacaine. Postoperative pain assessment will be conducted by mCHEOPS Children's Hospital of Eastern Ontario Pain Scale (request for rescue analgesic and complete analgesic dosage (mg.). Results: The PACU mCHEOPS pain score was lower in Group C at 2 hrs, 4 hrs and 6 hrs postoperative. Also, the time firstly needed for rescue analgesia was statistically significantly and lower in group C. The overall analgesic rescue requirement in Group C was also significantly lower. Conclusion: T Caudal block tended to be more effective in lowering postoperative pain scores and decreasing the need for rescue analgesia.
