Postoperative Wound: Effective Care and Rapid Healing

Introduction: The Importance of Proper Postoperative Wound Care

A postoperative wound is an inevitable part of any surgical intervention, requiring special attention and meticulous care. Proper wound management after surgery is critically important to prevent complications, accelerate the healing process, and ensure the best functional and aesthetic outcomes. The speed of the patient's recovery, as well as their overall well-being and quality of life after hospital discharge, depends on how competently this care is organized.

Stages of Wound Healing: What Happens After Surgery?

Postoperative wound healing is a complex biological process that typically goes through several consecutive stages:

• Inflammatory phase: Begins immediately after injury and lasts for several days. It is characterized by the cleansing of the wound from damaged tissues and microorganisms, as well as the influx of immune cells.
• Proliferative phase: During this period, new tissue (granulation tissue) actively forms, blood vessels grow, and epithelization occurs—the closing of the wound surface with new skin cells.
• Remodeling (maturation) phase: Lasts from several weeks to a year or more. During this time, collagen fibers reorganize, and the scar becomes stronger and less noticeable.

The speed and quality of healing are influenced by many factors, including the patient's general health status, the presence of comorbidities, and the adequacy of postoperative care.

Prevention of Complications: Key Aspects of Care

One of the most serious complications of the postoperative period is surgical site infection (SSI). According to a meta-analysis, the incidence of SSI in the surgical treatment of facial soft tissue injuries is about 3.30% [6]. Effective prevention of SSI and other complications includes several important areas:

• Aseptic dressings: Regular dressing changes under sterile conditions and treating the wound with antiseptics as prescribed by a doctor. This helps maintain wound cleanliness and prevents bacterial penetration.
• Wound monitoring: Careful observation of the wound allows for the timely detection of signs of inflammation or other issues.
• Specialized methods: For patients at high risk of developing SSI—such as those with obesity, diabetes mellitus, or immunosuppression after open abdominal surgery—prophylactic negative pressure wound therapy (pNPWT) may be recommended. A study showed that the use of pNPWT significantly reduces the incidence of SSI (from 35.6% to 5.3%), shortens epithelization time, and reduces hospital stay duration compared to standard dressings [5]. This method involves creating controlled negative pressure over the wound, which helps remove exudate, reduce edema, and improve blood supply.

Factors Influencing the Speed and Quality of Healing

The effectiveness of postoperative wound healing depends on a multitude of internal and external factors:

• Nutrition: Adequate intake of proteins, vitamins, and micronutrients is critically important for tissue regeneration. Low serum albumin levels on the second day after emergency surgery for perforated gastric or duodenal ulcers correlate with an increased length of hospital stay and risk of postoperative complications [8]. This emphasizes the importance of nutritional support in the early postoperative period.
• General patient condition: Age and the presence of chronic diseases (e.g., diabetes mellitus, cardiovascular pathologies, immunodeficiency states) can slow down healing and increase the risk of complications [5]. In elderly patients undergoing emergency surgery, recovery may take longer [4].
• Physical activity and rehabilitation: Early mobilization and adequate physical activity recommended by a doctor promote improved blood circulation and general bodily tone, which positively affects healing. For example, neurorehabilitation after endovascular procedures for ischemic stroke was associated with better outcomes [1].
• Adherence to medical recommendations: Strictly following doctor's instructions regarding wound care, medication intake, and activity restrictions is the key to successful recovery.

These results confirm the effectiveness of ERAS protocols in both elective and emergency surgery, including vulnerable patient populations such as the elderly [4].

Modern Approaches to Enhanced Recovery (ERAS)

Enhanced Recovery After Surgery (ERAS) protocols represent a comprehensive, multidisciplinary approach aimed at minimizing the stress of surgical intervention and accelerating patient rehabilitation. These protocols include the optimization of preoperative preparation, intraoperative management, and postoperative care.

Studies show significant benefits of ERAS:

• Reduction in hospital stay: In patients with perforated gastric ulcers who received enhanced postoperative recovery, the average length of hospital stay was significantly lower (6.93 days versus 12.3 days in the control group) [2]. Similar results were obtained in elderly patients who underwent emergency surgery for perforated ulcers, where ERAS protocols led to faster functional recovery and shortened hospital stays [4].
• Reduction in complication rates: The implementation of ERAS is associated with a decrease in postoperative complications [2, 4].
• Accelerated functional recovery: Patients following ERAS protocols demonstrate earlier recovery of intestinal peristalsis (first bowel movement, passing gas) [2, 4], which is an important indicator of normalized gastrointestinal tract function after abdominal surgeries.
• Pain reduction: ERAS protocols often include optimized pain management, which contributes to a more comfortable recovery [4].

When to See a Doctor: Signs of Trouble

Despite careful care, complications can sometimes arise. It is important to consult a doctor immediately if you notice the following signs:

• Increased pain in the wound area that is not relieved by regular painkillers.
• Redness, swelling, or elevated skin temperature around the wound.
• Discharge from the wound (pus, cloudy fluid, unpleasant odor).
• Separation of wound edges (dehiscence).
• Elevated body temperature (fever).
• General deterioration in well-being, weakness.
