Randomized Controlled Trial Comparative Study
[Spinal anaesthesia in day-case surgery. Optimisation of procedures].
Since prilocaine is being increasingly used for day case surgery as a short acting local anaesthetic for spinal anaesthesia and because of its low risk for transient neurological symptoms, we compared it to bupivacaine. ⋯ Under the present study conditions, hyperbaric prilocaine 2% was superior to hyperbaric bupivacaine 0.5% due to a shorter effect profile but otherwise equivalent quality of block. However, puncture in a sitting position and positioning with elevated torso for restriction of the cranial expansion of block spread might cause an enhanced sacral block with delayed recovery of bladder function.
