Randomized Controlled Trial Comparative Study Clinical Trial
Prospective to a randomized double-blind controlled trial to assess efficacy of double caudal analgesia in hypospadias repair.
A prospective, randomised, double-blind, controlled trial to evaluate efficacy of double-caudal versus single-caudal injection for postoperative analgesia in hypospadias repair was performed. ⋯ A prospective study of double caudal analgesia showed good postoperative pain control after hypospadias surgery. This was followed by a prospective, randomised, double-blind controlled trial that has confirmed that double caudal injection of bupivacaine prolonged the duration of pain relief after hypospadias repair. The second or top-up caudal did not increase the total dose but supplemented and prolonged postoperative analgesia.
