BACKGROUND AND OBJECTIVES Commercially available bupivacaine is a racemic mixture of S(-) and R(+) enantiomers. Although the S(-) bupivacaine enantiomer is less toxic than R(+) bupivacaine to cardiovascular and central nervous systems, its relative efficacy has not yet been determined in spinal anesthesia for pediatric surgery. The aim of this study was to evaluate the effects of spinal anesthe...

We have compared bupivacaine 5 mg ml-1, either isobaric in saline 0.9% or hyperbaric in 8% glucose, for spinal anaesthesia in 100 children, aged 2-115 months, in a double-blind, randomized, parallel group, prospective study. Children were premedicated with diazepam 0.5 mg kg-1 orally. Seventy-two children were sedated before, and 25 children after, lumbar puncture, with either propofol or thiop...
