290 OUR BODIES AND HOW WE LIVE 



When wounds are made with ragged edges, such as 

 broken glass and splinters, more skill is called for. Remove 

 every bit of the foreign substance. If the skin about the 

 wound seems to need washing, it should be done with an 

 antiseptic solution. Bring the torn edges together and hold 

 them in place with strips of plaster. 



Wounds made by rusty nails and tools, if neglected, 

 often lead to serious results from blood poisoning. Keep 

 such wounds clean by washing or syringing them twice 

 a day with antiseptics which kill the bacteria or prevent 

 their growth. 



Deaths following injuries from toy pistols and percussion 

 caps have become so frequent in recent years that it is not 

 safe to depend upon home treatment for such accidents. 

 All such wounds should be treated at 

 once by skilled physicians.

 in a proper way for a variety of imaginary cuts. 



After putting on the plaster, practice bandaging the parts with strips 

 of cotton cloth rolled for the purpose. Practice using the handker- 

 chief for a variety of bandages. 



401. Injuries to the Blood Vessels. It is very important 

 to know the difference between the bleeding from an artery 

 and that from a vein. If an artery bleeds, the blood leaps in 

 spurts and is of a scarlet color. If a vein bleeds, the blood 

 oozes in a steady stream and is of a somewhat darker color. 



Bleeding from an artery is dangerous in proportion to 

 the size of the vessel, and as a result life itself may be 

 speedily lost. In arterial bleeding, always remember to make 

 deep pressure between the wound and the heart.
