[Effects of increasing spinal hyperbaric lidocaine concentrations on spinal cord and meninges: experimental study in dogs].
Lidocaine concentration potentially able to determine nervous tissue injury is still not well established. This study aimed at investigating the effect of increasing spinal lidocaine concentrations in single injection through Quincke needle. ⋯ In this study, spinal lidocaine in concentrations above 7.5% in single injection through Quincke needle has determined histological changes on spinal cord, but not on meninges.
