take care of the great qaantity of fluid in the vessels and 

 tissues. A return to the normal volume, force, and rate of 

 the pulse, and of color to the mucous membranes, will lead 

 us to stop the saline infusion. The use of intravenous saline 

 injections is frequently followed by a reaction. within half an 

 hour, characterized by a severe rigor, succeeded by sweat- 

 ing, labored breathing, a strong pulse and increased urinary 

 secretion. 



Hypodermoclysis. 



Injection of warm (103° to 105° F.) normal salt solution 

 into the muscular tissue of the neck, abdomen or flank, is 

 done aseptically with the same apparatus employed for in- 

 travenous saline infusions, using a large hollow needle to 

 thrust under the skin directly into the muscular tissue, 

 instead of the glass tube for intravenous injection ; or a 

 fountain syringe filled with saline solution and attached 

 to a sterile aspirating needle may be used ; or a reversed 

 aspirator apparatus may be utilized : i.e., by filling the 

 jar with salt solution and forcing the air into the jar, 

 thus displacing the fluid. The fountain syringe is the 

 best apparatus. Hypodermoclysis may be employed in 

 the same cases as intravenous infusion, and is a better 

 method on account of its simplicity. We are guided as 

 to the quantity of solution desirable by the same indica- 

 tions noted above as referring to intravenous saline injec- 

 tions. Hypodermoclysis may be done in several places, 

 and absorption is assisted by massage. Salt solutions are 

 injected under the udder in females, and are occasionally 

 thrown into the peritoneal cavity, particularly after opera- 

 tions in this region, before closing the abdominal walls.
