The canula is first filled with the saline solu-tion, and is then connected with a funnel by means of arubber tube (Fig. 131), which is filled with saline solutionto displace the air, and upon raising the funnel above thepart the solution enters the vein; care should be taken tosee that the funnel is kept well supplied with the solutionuntil a sufficient quantity has been introduced. Thequantity introduced is regulated by the condition of thepatients pulse. Saline solution may also be introduced into a vein by Fig. Funnel and tube for intravenous injection. means of a syringe when the apparatus described cannotbe obtained. Infusion of Saline Solution—Hypodermoclysis.—The introduction of saline solution into the cellular tissuehas been followed by results equally as satisfactory as those ARTIFICIAL RESPIRATION. 149 obtained by intravenous injection, and this procedure isnow very frequently employed. The saline solution is conveyed into the cellular tissuethrough a large hypodermic needle, which should be ster-ilized by boiling, and is then introduced into the connec-tive tissue, being previously connected by a rubber tubewith a reservoir containing warm sterilized salt usual situations for the introduction of the solutionare the external portions of the thighs and the anteriorand lateral portions of the abdominal walls. As much astwo or three pints of the solution are often introduced inthis manner, with good results. Infusion
