“Ethyl Chloride spray can be used to freeze a small local area of skin for punctures, skin biopsy, or incision of small abcesses. Ethyl Chloride is sprayed on the skin for 3 to 7 s from an inverted bottle and a distance of 10 to
20 cm, with the jet aimed so that it meets the skin at an acute angle to lessen the shock of impact. Surface anaesthesia results from cooling (<4 o C) which occurs during the evaporation process

“ Conclusions and Clinical Relevance —Vapocoolant spray was safe and effective in reducing horses' responses to arthrocentesis. The use of such products prior to joint injections may reduce procedural nociception and pain anticipation in unsedated horses and may improve the safety of personnel performing such procedures.”
“Ethyl chloride acts as a local analgesic (pain relief) when sprayed topically onto the skin. It has no anaesthetic properties but rather works as a vapo-coolant. A thin film of liquid is sprayed onto the skin, which makes the skin cold and less sensitive as the liquid evaporates. It works very quickly (in a few seconds) but the effect wears off quickly too as the skin warms up again in a few minutes. It can be very useful for children who are allergic to topical anaesthetics, or for those who get very upset when the cream is applied before tests.”
