A Comparison of the Postoperative Analgesic Efficacy of Two Different Doses of Caudal Clonidine as Adjunct to Caudal Bupivacaine in Infraumbilical Surgeries in Younger Children.

Managing peri operative pain in smaller children is challenging but beneficial. Caudal epidural block with local anaesthetic and adjuvant in proper dose can significantly prolong the duration of analgesia while avoiding dose related side effects of both the drugs. We selected clonidine as adjuvant to bupivacaine in caudal blocks for perioperative pain management in 80 children during infra umbilical surgeries performed under general anaesthesia. MethodsThe children were randomly allocated into two groups, Group A (n=40) and Group B (n=40). Group A received caudal bupivacaine (0.125%) 0.75 mL/Kg plus clonidine 1 μg/Kg in 1 mL normal saline and Group B received caudal bupivacaine (0.125%) 0.75 mL/Kg plus clonidine 0.5 μg/Kg in 1 mL normal saline, after inhalational anaesthesia. Heart rate, blood pressure, respiratory rate, oxygen saturation, sedation score, Bromage score and pain score were monitored and recorded peri-operatively. Time to first rescue analgesic at pain score of 12, total number of rescue analgesic doses required, and side effects were also recorded. Data was analysed using appropriate statistical tests. ResultsGroup B patients had significantly higher heart rates, systolic and diastolic blood pressures, respiratory rates and pain scores compared to Group A patients at 50 mins post operatively. The requirement of rescue analgesics in Group B was earlier and higher than Group A. Group A patients remained haemodynamically stable and pain free for longer period. There was no significant difference in side effects between the groups. ConclusionsAddition of 1 μg/Kg clonidine to caudal epidural bupivacaine improves the quality and prolongs the duration of postoperative analgesia compared to addition of 0.5 μg/Kg clonidine without causing significant side effects.
