Abstract: Caudal epidural analgesia is one of the most commonly performed regional techniques in paediatric anaesthesia for intra and post-operative analgesia. However, the duration of analgesia is limited by the duration of action of local anaesthetics. Addition of opioids like morphine, fentanyl is associated with side effects like respiratory depression, urinary retention and pruritus. Dexmedetomidine a α2 agonist is known for its analgesic effects with lesser side effects. Hence, this study was conducted to know the efficacy and safety of addition of dexmedetomidine to bupivacaine in a single shot caudal block in children. This study was conducted among 60 children in the age group of 1 – 10 years coming for various elective infraumbilical surgical procedures. They were divided into two groups of 30 each. Group B received caudal 0.25% bupivacaine 1ml/kg and group D received caudal 0.25% bupivacaine 1ml/kg with dexmedetomidine 1 μg/kg. The pain score in the two groups were similar up to 2 hours after surgery but was higher in group B at the end of 3rd and 4th hour compared with group D. This study showed that the addition of dexmedetomidine in the dose of 1μg/kg to 0.25% bupivacaine 1ml/kg reduced the anaesthetic requirement, prolonged the duration of analgesia with less post operative analgesic requirement after a single shot caudal block with minimal side effects in children.
