Spinal anesthesia using small amounts of tetrodotoxin or desoxytetrodotoxin

摘要

Vertebrates can be anesthetized regionally by a subarachnoid administration of tetrodotoxin or desoxytetrodotoxin. The amount of tetrodotoxin which should be administered in a preferred embodiment ranges between 1 and 12 micrograms, whereas the amount of desoxytetrodotoxin ranges between 10 and 120 micrograms.
