Comparative Study of Spinal Anesthesia by Bupivacaine Heavy (0.5%), Bupivacaine Heavy (0.5%) with Ketamin or Midzolam in Paediatric Patients

Abstract

Background: Various anatomical and physiological differences make neural blockade in paediatric surgery different from that in adults. Recent availability of preservative free midazolam and ketamine used as adjuvants, prompted us to take up this study to explore the advantages to be gained by the use of these adjuvant drugs in spinal anaesthesia. The aim of this study was to evaluate spinal anaesthesia in children by using 0.5% bupivacaine which and either preservative free ketamine of preservative free midazolam adjuvants to 0.5% bupivacaine. Materials and Methods: In 60 patients of 7-12 age group years posted for routine surgeries below the level of umbilicus were included after fitness according to ASA grading I and II. Group I received spinal anaesthesia using bupivacaine heavy 0.5%, Group II received spinal anaesthesia using bupivacaine heavy 0.5% with preservative free ketamine, Group III received spinal anaesthesia using bupivacaine heavy 0.5% with preservative free midazolam. Observation: There was statistically no significant (p>0.05) difference between mean values of onset of sensory blockade (min) and height of sensory blockade in the three groups. While statistically highly significant (p
