Wound dehiscence (separation) is influenced by systemic factors like diabetes, malnutrition, obesity, steroid use, and malignancy, alongside local factors such as infection, poor blood supply (ischemia), increased wound tension (coughing, distention), and devitalized tissue, all impairing the critical healing process by disrupting cellular repair and collagen formation.
The causes of dehiscence are similar to the causes of poor wound healing and include ischemia, infection, increased abdominal pressure, diabetes, malnutrition, smoking, and obesity. [1] Superficial dehiscence is when the wound edges begin to separate and by increased bleeding or drainage at the site.
Factors Affecting Wound Healing
Common Causes of Wound Dehiscence
Medical conditions that increase wound dehiscence include:
SYSTEMIC STRATEGIES TO PREVENT DEHISCENCE
Research has shown that surgery length plays a role; if an operation is longer than two and a half hours, there is an increased chance of dehiscence. In addition, people who need emergency surgery are more likely to have wounds that dehisce than are patients who have scheduled surgery.
Wound Dehiscence Treatment
Mild cases of partial dehiscence may be managed with proper wound care, antibiotics, and close monitoring. However, in more severe cases, especially complete dehiscence, surgical intervention may be needed to properly close the wound and prevent further complications.
Factors that can slow the wound healing process include: Dead skin (necrosis) – dead skin and foreign materials interfere with the healing process. Infection – an open wound may develop a bacterial infection. The body fights the infection rather than healing the wound.
possible indicators of dehiscence may be: a sudden pain around the wound area; tachycardia; abnormal and/or excessive serous or sero-sanguineous discharge; opening of the wound; change in wound contour; viscera visible at the skin surface; abnormal serous or sero-sanguineous discharge.

5 Factors That Affect Wound Healing
with poor circulation. This may be due to local pressure, vascular disease or diabetes. Poor nutrition/malnutrition - Nutrition has a significant impact on wound healing. Lack of protein will result in insufficient building blocks for cell regeneration.
Diabetes is one of many factors that can increase the risk of dehiscence and impede wound healing in general. The disease can impact blood circulation, slow wound healing, and affect the immune system, making these patients more susceptible to complications like infection.
Wound dehiscence usually happens within 3-10 days after the operation. This can be due to infections, injuries, early stitch removal, weak tissue in the area of the wound, incorrect suture technique, or stretching of the wound due to lifting, vomiting, or coughing violently.
The good news is that wound dehiscence is treatable. The choice of treatment depends on several factors, including the extent of the dehiscence and the presence of infection. Treatment options include wound care, resuturing, wound dressings, or even surgical revision.
Vitamin C deficiency has been found to impair wound healing and has also been associated with an increased risk of wound infection. Research has shown vitamin C supplementation helps promote pressure ulcer healing.
The panel identified 4 major barriers to wound healing and used the T.I.M.E acronym as an easy reminder of those barriers: Tissue nonviable or deficient, Infection or inflammation, Moisture imbalance, Edge of wound non- advancing8.
Eating well during wound healing helps you heal faster and fight infection. During healing your body needs more calories, protein, fluid, vitamin A, vitamin C, and zinc. The best source of these nutrients is food. If you are not eating enough healthy food, you may need to take a supplement.
Below, we share the best beverages to support a smooth, efficient healing process.
So, what is the hardest wound to heal? The answer lies in chronic wounds, particularly diabetic foot ulcers, pressure ulcers (bedsores), and venous leg ulcers.
Don't use abrasive or rough washcloths for skin care and wound healing. Don't scratch dry, itching areas. Scratching can cause further skin damage and increase the risk of infection, which can impede the healing process. Don't apply tape of any kind to dry, sensitive, fragile skin.
Simple wound care is all that is required in the majority of cases, with regular wound packing and cleaning with sterile saline. The patient should be advised the wound will heal by secondary intention as a result of the dehiscence and that this can take several weeks.
Poor Circulation
During the healing process, your body's red blood cells carry new cells to the site to begin rebuilding tissue. Poor blood circulation can slow down this process, making the wound that much longer to heal. Chronic conditions, such as diabetes and obesity, can cause poor blood circulation.
Uterine scar dehiscence can complicate caesarean section with complications like post partum hemorrhage, endomyometritis, localized/generalized peritonitis, and sepsis.
