A wound is an injury to living tissue caused by a cut, blow, or other impact, usually an injury in which the skin is cut or broken. The skin is the largest organ in the human body, making up 15% of the human body. It is responsible for the temperature and protection of the body from various external influences. Wound healing is the body's normal response to injury, surgical or traumatic, causing disruption of tissue integrity. Surgical wounds are classified according to their degree of microbiology (2014 Advanced Tissues). Class I - clean - an uninfected surgical wound in which no inflammation is encountered and in which the uninfected respiratory, food, genital or urinary tract is not penetrated. In addition, clean wounds are first closed and, if necessary, drained with closed drainage. Incisional surgical wounds following non-penetrating trauma should be included in this category. If they meet the criteria, the infection rate for Class 1 wounds is 1-5%. No drainage is necessary. These wounds are common during eye surgeries, small skin incisions, and vascular and neurological procedures. To be considered a clean wound, the procedure must not involve any prior rupture of membranes before surgery (CDC Guideline 1999). Include any open wounds for drainage, as well as procedures including the digestive, urinary and respiratory tracts. , yet entered without causing much trauma to the tract. Other clean and contaminated wounds include procedures in which an organ or body part has suffered a rupture. Some common clean contamination procedures include ear surgery on an infected ear, removal of pins or wires from previous surgeries as well as C-sections which include a break before the procedure is preferred..... . middle of paper ...... The final phase of healing, when scar tissue forms. The wound has a high bacterial content, a wound has passed for a long time since the injury or wounds with a severe crush component with significant temporal devitalization. The wound edges are brought together within 3 to 4 days and tensile strength develops with primary closure (wound healing phases). Wound Healing Complications, There are various complications that can arise during the wound healing process. These types of situations can be life threatening and one must be able to recognize the seriousness of these signs and stop things that may occur before complications become life-threatening. Bleeding from the wound may ooze, bleeding may indicate slipped sutures and trauma to blood vessels or tissues. Dehiscence may occur; this is when the layers of the wound separate, patients can suffer from complications after this
