Текст A. Desmurgiya
Desmurgiya (от греч. δεσμός — «связь, повязка» и έργον --«дело») — is a part of medicine studying the rules of wound treatment, dressings and the methods of their applying.A wound is any break in the
skin or mucus membrane. Wounds include cuts, scrapes, scratches and punctured skin. They often occur as a result of an accident or injury, but sur-gical incisions, sutures, and stitches also cause wounds. Minor wounds usually aren't serious, but even cuts and scrapes require care.Serious and infected wounds require medical attention. You should also seek attention if the wound is deep, if you cannot close it yourself, if you cannot stop the bleeding or get the dirt out, or if it does not heal. There are dif-ferent types of wound treat-ment, and the type a patient receives will depend on the injury being treated.
