The best drop bottle is prepared as follows(Fig. 66) : Cut the lead cap neatly out of the ether can. Take theether can cork and cut two deep grooves in the sides. Inone of the grooves place a little wick of cotton (not gauze) ;leave the other groove free for the admission of air. Placethe cork with the cotton wick in the can; allow the wick tobecome soaked with ether, which will drizzle off the frayedend. With a pair of scissors, cut the wet wick so that theend is square instead of frayed. A large, clean drop, whoserapidity is easily controlled, is then obtained. An emer-gency drop bottle may be provided by making a singlepinhole in the centre of the lead cap in a can of ether, which. ETHER ANESTHESIA 125 has not been opened. If the can is now grasped in thepalm of the hand, the rise in temperature resulting willcause the ether to spray out when the can is inverted. Adrop may then be secured by controlling the spray withthe finger tip. The Administration.—When the open drop method isemployed, ether, as a rule, is the sole anaesthetic may sometimes render the induction more pleasantfor the patient by dropping upon the mask a little essenceof orange, wintergreen or some pungent essential oil,before the ether is given. This occasionally serves to maskthe disagreeable odor. The trick of a smooth induction,however, consists in two things: First, in causing the pa-tient to breathe somewhat more frequently and deeply thannormal. Secondly, in the control of the drop so that therewill be no spasm of the respiration. One of the bestmethods of controlling the respiration is to ask the patientto count slowly and loudly.
