Background: The caudal epidural block is one of the most commonly used regional techniques for post-operative pain management in pediatric age group patients undergoing infraumbilical surgeries. Adjuvants use increases the duration of analgesia and decrease local anesthetic dose requirement so decreasing the risk of toxicity.
Aims and Objectives: The aim of present study was to evaluate and compare the efficacy of caudal block with 0.25% levobupivacaine 1 mL/kg and 0.25% levobupivacaine 1 mL/kg+dexamethasone 0.1 mg/kg for post-operative pain relief in pediatric patients undergoing infraumbilical surgeries. The secondary objective of the study was to compare hemodynamic parameters and side effects if any.
Materials and Methods: A prospective, randomized, comparative, and double-blind study design was conducted in 60 patients in JAH super specialty group of hospitals. All patients belonging to physical status of American Society of Anesthesiologists Grade I and II, aged 1–6 years, were randomly allocated into two groups: Group 1 (n=30) received levobupivacaine 0.25% 1 mL/kg in 0.5 mL saline and Group 2 (n=30) received levobupivacaine 0.25% 1 ml/kg with dexamethasone 0.1 mg/kg for caudal block in pediatric patients undergoing infraumbilical surgeries. Primary outcome was duration of analgesia using face, legs, activity, cry, and consolability scale at interval of 0, 15, 30, 60, 90, 120, 150, and 180 min postoperatively. The secondary outcome of study included hemodynamic parameters and adverse events during the post-operative period.
Results: The mean duration of analgesia in Group 1 (L) was 430.77±16.71 min and in Group 2 (L+D) was 805.00±36.71 min with statistically significant result.
Conclusion: On adding dexamethasone to levobupivacaine in caudal block significantly prolongs duration of analgesia in post-operative period. It also provides more hemodynamic stability during intraoperative and post-operative period and associated with minimal side effects.
