Individuals at greatest risk for wound dehiscence (wound separation) are often older adults, smokers, obese, diabetic, malnourished, or have compromised immune systems, chronic conditions like COPD, anemia, or infections, and undergo lengthy or emergency surgeries, with post-operative factors like coughing, vomiting, or increased abdominal pressure also significantly raising risk.
more at risk of wound dehiscence if they are over 65 years old, have signs of systemic and local wound infection, are obese, or have had a previous surgery in the same anatomical region[18]. Most dehiscence occurs 4–14 days following surgery[4,5,7–9,19].
Patients older than 65 years are more likely to develop wound dehiscence because of deterioration in tissue repair mechanism compared with younger patients [3]. Other well-known risk factors include hypoproteinemia, local wound infection, anemia, hypertension, and emergency surgery [1].
Medical conditions that increase wound dehiscence include:
Common risk factors for abnormal healing include the presence of necrotic tissue, infection, ischemia, smoking, diabetes, malnutrition, glucocorticoid use, and radiation exposure. When dehiscence is identified, it is crucial to determine the extent of wound failure.
The symptoms of wound dehiscence can vary depending on the severity and location of the dehiscence, but common signs include: Visible Separation: The most obvious symptom is the visible partial or complete opening of the wound. Increased Pain: The patient may experience increased pain at the surgical site.
burns; animal bites; any type of penetrating wound, such as from a rusty nail or rose thorns; and. wounds contaminated with soil, manure or foreign objects such as wood fragments.
People who smoke cigarettes and drink alcohol are more likely to experience slower healing rates than those who don't smoke or drink. Both habits inhibit wound healing by suppressing your body's inflammatory response and restricting the flow of blood, oxygen, nutrients, and reparative cells to the injured area.
The two categories of dehiscence are partial dehiscence when only a wound's edges pull apart and complete dehiscence when the entire site reopens and exposes layers of underlying tissue, muscle, and sometimes, organs.
Issues that come up can include:
Wound healing, as a normal biological process in the human body, is achieved through four precisely and highly programmed phases: hemostasis, inflammation, proliferation, and remodeling.
The four main types of open wounds are abrasions, lacerations, avulsions and puncture wounds and they may occur together.
Obesity has been identified as the single most important risk factor for postoperative sternal infection in coronary bypass surgery patients. It is also a major risk factor for sternal dehiscence, with or without infection, for any type of cardiac operation.
Proper bandage and external support can be critically important to preventing dehiscence in areas subject to motion or weight-bearing. Care and proper bandage care are used to avoid circulatory compromise during bandage application.
The split can happen in just the skin layers, or the entire wound can open back up. Wound dehiscence often can happen with abdominal surgeries, such as C-sections (when babies are delivered through an incision in the abdomen) and laparotomies (which allow doctors to examine the abdominal organs).
For example, infants (up to 2 years old) and older adults (aged 65 or older) are at higher risk for developing infections due to underdeveloped or weakened immune systems. Additionally, anyone with chronic medical conditions (such as diabetes) are also at higher risk of developing an 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.
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.
The most cited cause includes infection and high tension on the wound edges. Other risk factors include tobacco use, lengthy operative times, obesity, and large resection volumes. Local wound management and healing by secondary intention is appropriate for partial dehiscence.
5 Factors That Affect Wound Healing
Patients suffering from diabetes and obesity are at high risk of developing chronic wounds. Vast majority of people who have a prolonged open wound usually also have other major health conditions. The simultaneous presence of a combination of chronic diseases is called comorbidity.
Puncture wounds can be challenging to clean and may carry a higher risk of infection. - Examples: Injuries from nails, needles, or animal bites.
However, the most severe wounds we treat often involve infected ischemic diabetic foot ulcers and stage 4 pressure ulcers, which are also called bedsores. They are the hardest to treat and the ones that also bring the biggest consequences and complications to patients.
Coronary artery disease, peripheral vascular disease, cancer, and diabetes mellitus are a few of the chronic diseases that can compromise wound healing. Patients with chronic diseases should be followed closely through their course of care to provide the best plan. Immunosuppression and radiation therapy.
