Randomized Controlled Trial Clinical TrialEffect of aspiration of cerebro-spinal fluid on spinal anaesthesia with isobaric 0.5% bupivacaine.
The effect of changing the volume of cerebro-spinal fluid (CSF) before spinal anaesthesia with 3 ml of isobaric 0.5% bupivacaine was investigated in 60 elderly (58-77 years) orthopaedic or urological patients. The patients were randomly allocated to three groups. They received the spinal anaesthetic either with or without the aspiration of 3 ml of CSF. ⋯ The anaesthesia was satisfactory in most cases. One death occurred because of a massive pulmonary embolism. The clinical significance of aspirating CSF before attempting spinal anaesthesia with 3 ml of 0.5% isobaric bupivacaine was found to be small.
