I have lately noticed in The Journal various articles on the use of ethyl chlorid as a short general anesthetic, and some specially constructed masks.
To my mind the latter are too expensive for the general practitioner, and I desire to present a method that I use in the receiving ward of the Cincinnati Hospital.
With the patient on his back, I place over his mouth and nose two layers of thin gauze. Over this I place a tin or glass funnel around the bottom of which is wrapped a towel, as shown in the accompanying illustration. The ethyl chlorid is sprayed down the small end of the funnel.
The gauze keeps the nose from being frozen, and the towel prevents too great a loss of ethyl chlorid, yet gives free access of air, so that the vapor can not be too concentrated. The patient readily goes to sleep.
