Dexmedetomidine Sedation Versus General Anaesthesia for Inguinal Hernia Surgery in Infants

Summary

This is a prospective randomized controlled trial comparing dexmedetomidine sedation with caudal anaesthesia, and general sevoflurane anaesthesia with caudal anaesthesia for inguinal herniotomies in neonates and infants below 3 months of age. The investigators will compare the efficacy and adverse events associated with each of these techniques and neurodevelopmental outcomes of the infants in each group at 6 months and 2 years of age.
