Optimum Concentration of Caudal Ropivacaine & Clonidine - A Satisfactory Analgesic Solution for Paediatric Infraumbilical Surgery Pain.

Introduction: Ropivacaine is amide local anaesthetic pure S(-)enantiomer of bupivacaine. Its duration of analgesia is similar to that of Bupivacaine (in equivalent doses) but the motor block is slower in onset, less intense, shorter in duration for a given level of sensory block with lesser cardiac side effects but addition of an adjuvant like clonidine which is an imidazoline derivative has been studied for its sedative, anxiolytic and analgesic properties.

Aim: This study was aimed to show the optimum concentrations of Ropivacaine and Clonidine to maximize analgesia without side effects by evaluating its safety and efficacy.
