BACKGROUNDRegional anaesthesia plays an enormous role in providing pain relief both in the intra-operative and post-operative periods in paediatrics. Caudal epidural anaesthesia is the most commonly performed regional anaesthetic technique in children. The availability of newer drugs with reduced toxic potentials led us to conduct a study in which we compared the duration of postoperative analgesia between the drugs for infraumbilical surgeries.To compare Bupivacaine and Ropivacaine in a concentration of 0.25%, given in a volume of 1 mL/kg through a single Presurgical Caudal block in children aged 2-8 years undergoing surgeries like herniotomy and circumcision in terms of duration of postoperative analgesia.
MATERIALS AND METHODSThe present study was carried out in the Department of Anaesthesiology, Govt. Chengalpattu Medical College, Chengalpattu, in 60 patients of either sex of ASA Grade I, between the ages of 2 and 8 years. These patients were systematically randomised into groups of 30 each, Group A received 1 mL/kg of 0.25% Bupivacaine (0.5% solution diluted in equal volumes of normal saline) and Group B received 1 mL/kg of 0.25% Ropivacaine (0.5% solution diluted in equal volumes of Normal Saline) through the caudal route.Statistical Analysis -The data was analysed by statistical software SPSS 17.0 and XLSTAT 2013. Independent student 't' test was used to find the significance in continuous data between the two groups. Chi-square test was used to analyse categorical data.
RESULTSThe two groups were comparable in their baseline characteristics like age, sex, weight, height, vital signs, duration and type of surgery. The duration of postoperative pain relief between the groups were 182.83±12.64 mins. in Group A and 110.17±8.66 in Group B with a P < 0.001. The time to full motor recovery was significantly less in Ropivacaine group than in bupivacaine group. In Group A 239.00±21.55 mins. and in Group B 162.00±20.24 mins. with a P < 0.001.
CONCLUSIONCaudal Bupivacaine 0.25% in a dose of 1 mL/kg provided reliable and long lasting analgesia when compared to Ropivacaine 0.25% in children undergoing infraumbilical surgeries.
