How to prevent suppuration
Boys and girls cannot do all this before they cut their hands or skin their shins, but they can do the next best thing—they can keep their hands and the rest of their bodies clean at all times, and thus have as few germs on them as possible. Then, when they have cut themselves, they can go straight to some place where there is soap and water, and can wash the wound thoroughly. After this is done, a clean bandage should be placed on the cut part to prevent any other germs from getting in. If this is done every time you cut yourself, you will probably never have an infection—that is, a wound that suppurates.
Two boys were playing together one day. They ran into each other and each got a little cut on his hand. One boy went home at once, washed the wound, and put on a clean bandage. He lost a little time from his play, but was soon back and never had any trouble on account of the cut. The other boy thought it was foolish to quit his play to take care of such a little thing, so he tied his hand up in a dirty handkerchief. Two weeks later he was very ill. His arm was badly swollen and had to be cut open in several places; indeed, he came near losing his arm. It always pays to take care of a wound, be it never so slight.
Deep wounds made with small instruments, such as small knives, nails or toy pistols, are especially dangerous, because they are hard to clean and because they quickly heal up on the surface and leave the germs to grow at the bottom of the wound. Such wounds as these are dangerous for another reason.
Where germs of lockjaw grow
There is a germ that gets into wounds but does not cause suppuration. It is the germ of tetanus, or lockjaw. It lives in the ground, especially in the ground about barns, and its peculiar feature is that it will not grow in the air. If it gets into a large, open wound, it is easily killed, because it cannot grow where there is air. But when it gets into a small, deep wound where it cannot be reached, it stays there until the wound heals over on the surface, and then it begins to grow. It does not make the parts swell, as the germs of suppuration do, but quietly continues to grow, without the wound showing any sign of infection. Finally it develops a very severe poison that is taken up by the blood; then the victim suddenly begins to have spasms about the face, and finally these spasms extend to the entire body and kill him. Whenever you get a wound so deep that you cannot wash it thoroughly, go to a doctor and let him clean it out with some medicine that will kill the germs that cannot be reached by washing.
How boils are caused
Sometimes the germs that cause suppuration get under the skin at a point where a hair has been pulled out, or even work down beside the hair itself. When this happens, they cause suppuration under the skin, and the result is a boil. A boil is merely an infection with the germs that cause suppuration.
Questions. 1. How do germs get through the skin? 2. Can we get rid of all the germs that cause suppuration? 3. Why is it impossible for "bad blood" alone to cause suppuration? 4. How does the surgeon prevent suppuration? 5. How may you prevent suppuration? 6. What is the danger of cutting corns with an ordinary knife or razor? 7. Where do germs of lockjaw grow? 8. What causes boils?
Remember. 1. Germs and not "bad blood" are the cause of suppuration. 2. Always keep as clean as possible, and immediately wash any cut, no matter how small. 3. If you have a deep wound, go at once to a doctor, and let him clean it out and kill the germs that may be at the bottom of the wound.
