It is a woman’s nature to love beauty, and the most important concern of many new mothers after cesarean delivery is the wound on the stomach, in addition to the child. Surgical incisions can be divided into three categories: clean incisions, represented by “I”, are non-traumatic, uninfected wounds; sterile incisions with sutures, such as subtotal thyroidectomy, etc. Potentially contaminated incisions, represented by “II”, are sutured incisions that may be contaminated during surgery, such as cesarean wounds and lateral incisions. Areas where the skin is not easily and thoroughly sterilized are in this category. Contaminated incisions, represented by “III”, are incisions near infected areas or where the tissue is directly exposed to infected materials, such as septic appendicitis surgery and surgical wounds with necrotic intestinal obstruction. Not only the wounds are graded, the wound healing is also classified according to the grade, generally divided into three grades: Grade A healing, represented by “A”, refers to excellent healing, no adverse reactions to the initial healing. Grade B healing, represented by “B”, refers to poor healing, with inflammatory reactions at the healing site, such as redness, swelling, hard nodes, hematoma, fluid accumulation, etc., but no suppuration. Grade C healing, represented by “C”, means that the incision is septic and needs to be cut and drained. Recording method: If the wound healing after cesarean section is excellent, it will be recorded as “II/A”. The wound healing process is divided into four phases: coagulation phase, inflammation phase, repair phase, and maturation phase. Coagulation phase: From the moment of wound formation, the first reaction of the body is its own hemostatic process. This process includes some very complex biological reactions. Inflammatory phase: from the first 2-3 days of trauma formation onwards. The repair phase: can be divided into 2 stages: epithelial regeneration and granulation tissue formation,? 2-24 days from the formation of the trauma. Maturation phase: When the wound is completely covered by regenerated epithelial cells, the healing process of the wound is not completely finished. This is the maturation period of the trauma. This is because the new granulation tissue and epithelial cells need to further divide and differentiate and transform to make them stronger before finally allowing the wound to heal completely. There are many factors affecting wound healing, which can be generally categorized into local and systemic factors. Local factors: including infection, foreign body residue, insufficient local braking, local blood circulation status, surgical operation, dressing change method, etc. Systemic factors: including age, obesity, malnutrition (mainly hypoproteinemia and deficiency of vitamins, trace elements zinc, iron, copper, manganese, etc.), the influence of drugs and radiation, systemic diseases (such as diabetes, uremia, liver disease, leukemia, allergic diseases or AIDS, etc. all affect wound healing), smoking, psychological factors. Treatment of wounds: red potion: that is, 2% mercury bromine red solution, mainly sterilization, disinfection, antisepsis and promote the role of wound healing, but poor antibacterial effect, and contains organic compounds of mercury, harmful to humans, is rarely used. Purple potion: can accelerate wound healing, commonly used for superficial skin, not suitable for knife wounds or sharp stab wounds. Hydrogen peroxide: hydrogen peroxide, with disinfection and sterilization, but the concentration is large, easy to burn the skin of the wound, mainly for a certain infection of superficial local wounds. Boric acid water: cleaning, astringent and antibacterial effect, commonly used for skin, mucous membrane and wound rinse cleaning, stomatitis gargle. Iodine: mainly used for surface disinfection of non-mucosal wounds. Commonly used for skin disinfection before surgery, injection and wound disinfection. It is generally not used for ulcerated wounds and is prohibited for people with iodine allergy. Pay attention to the concentration when using, otherwise there will be skin burns. Iodophor: It is mainly used for surface disinfection of non-mucosal wounds. It is easy to use, non-irritating and odorless, and can be applied directly to the lateral cut wound without pigmentation. Alcohol: The concentration of medical disinfectant alcohol is 70%-75%. It is generally used for disinfection and sterilization of wounds after caesarean section.
