Formalin Blocks Nerve Conduction

Formalin Blocks Nerve Conduction 

In vitro
  • At concentrations of 10 mM and higher, formaldehyde can completely block nerve conduction in A and C fibers. At 30 mM, formaldehyde can irreversibly block all A fibers, but some slow C fibers may survive. 
  • In vivo
    In pilot experiments with rat skin, high concentrations of formaldehyde can transiently excite and then block all sensory nerve endings. This is followed by a second phase of discharge in small Aδ- and C-fibers.
