Comparative Study
Intrathecally administered ropivacaine is less neurotoxic than procaine, bupivacaine, and levobupivacaine in a rat spinal model.
The aim of this study was to compare the neurotoxicity of intrathecal procaine, bupivacaine, levobupivacaine, and ropivacaine in an animal model. ⋯ All four local anesthetics seemed to cause identical neurotoxic lesions commencing in the PR and extending to the PC by axonal degeneration. Bupivacaine appeared to be the most neurotoxic of the four drugs, and the neurotoxicity at higher doses increased by volume with procaine > levobupivacaine > ropivacaine.
