How long do I spray Ethyl Chloride on the procedure site?
Spray Ethyl Chloride to the site for 4 to 10 seconds from the can or 3 to 7 seconds from the bottle. Both the can and bottle should be sprayed from a distance of 3 to 9 inches until the skin begins to blanch. The length of time will depend on the skin’s sensitivity to cold; plus a number of variables such as differences in blood flow, sensory perception, weight, fat content, metabolism etc. The practitioner needs to be observant while spraying. When the skin begins to turn white, the numbing has taken effect and it is time to stop spraying. Do not frost the skin.
