Created: 16/9/2005
This is use of extreme cold to damage peripheral nerves and provide pain relief that lasts for several months. This technique causes axonal degeneration without epineural or perineural damage, allowing slow regeneration of the axon without neuritis or neuroma formation.

Compressed gas (CO2 or N2O) is passed through a narrow tube and allowed suddenly to expand at its tip. The work done by the gas as it expands results in a temperature drop (Joule-Thomson effect) and is an example of an adiabatic change. Temperatures reach -70oC.

[William Thomson (Lord Kelvin) 1824-1907, Irish born Scottish physicist].
