In cases of shockin which strychnin has been administered before the salineinfusion is started there is always a risk that the saline infusionwill cause the strychnin to be absorbed too rapidly. In suchcases symptoms of strychnin poisoning may develop. Intravenous Infusion without Dissection.—A needle having ancbtuse-angle point (Fig. 157) is substituted for the intravenous.

Without previous dissection the needle is thrust intothe distended vein at an oblique angle while the saline is the procedure is the same as ordinary intravenousinfusion. With a little practice the introduction of the needleinto the vein is quite simple.
