Introduction
Caudal epidural block is a reliable technique in paediatric patients but associated with various complications especially with higher concentration of drugs. We proposed a comparative study between levobupivacaine and ropivacaine at low concentration (0.125%) with clonidine at low dose (1 mcg/kg) taken as adjuvant. We aimed to see duration of post-operative analgesia, degree of motor blockade and other associated complications.
Materials and Methods
Eighty paediatric patients (1–6 years), American society of anaesthesiologists grade I and II, undergoing infra-umbilical surgery under general anaesthesia were randomly allocated into two groups of 40 each. Group A patients were given caudal levobupivacaine (0.125%) and Group B patients were given caudal ropivacaine (0.125%). Clonidine (1 mcg/kg) was taken as adjuvant in both the groups. Post-operative pain, sedation and motor blockade were assessed at 30 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, 18 hours and 24 hours using Observational Pain Scale, modified Bromage Scale and four-point sedation score, respectively. Any other complications were also noted.
Results
Motor blockade was not associated with any of the patients. Duration of post-operative sedation was similar in both the groups. Duration of post-operative analgesia was significantly higher in Group A (p < 0.0001). Adverse effects and complications were negligible in both the groups.
Conclusion
Both levobupivacaine and ropivacaine can be used safely at low concentration (0.125%) taking clonidine at low dose (1 mcg/kg) as adjuvant in paediatric caudal epidural block without significant motor blockade and other complications, duration of post-operative analgesia being significantly higher in the levobupivacaine group.
