Which finding would indicate the most concerning complication requiring immediate intervention? ## 보기 1. Serosanguineous drainage on the dressing with mild erythema around the incision edges 2. Sudden increase in serosanguineous drainage with visible separation of wound edges **✔ 정답** 3. Small amount of purulent drainage with localized warmth at one end of the incision 4. Moderate edema around the incision site with patient reporting increased pain rated 6/10 **정답: 2** ## 해설 Sudden increase in serosanguineous drainage with visible wound edge separation indicates wound dehiscence, a serious complication requiring immediate intervention to prevent evisceration. Other findings suggest infection or normal healing. ## 심화 해설 Understanding Wound Dehiscence as a Critical Postoperative Complication When assessing a surgical wound, your primary goal is to differentiate between the expected inflammatory healing response and the onset of a true surgical emergency. On postoperative day 5, the wound is typically in the proliferative phase of healing, where collagen is being laid down, but the tensile strength of the wound is still only a fraction of normal tissue. This is a critical window where mechanical stress or underlying infection can lead to catastrophic failure of the wound closure. Analysis of the Correct Answer The correct answer is the sudden increase in serosanguineous drainage with visible separation of wound edges. This presentation is the clinical definition of acute wound dehiscence. The term "sudden increase" is the key differentiator here, as it signifies a mechanical failure of the suture line rather than a gradual infectious process. The visible separation of the wound edges, or "gaping," indicates that the fascial layers have pulled apart. As highlighted in the provided case reports, surgical wound dehiscence is a life-threatening postoperative complication directly related to a failure of wound healing [1]. The serosanguineous fluid you observe is not a new exudate but rather peritoneal or tissue fluid that is now leaking through the disrupted closure. This situation requires immediate intervention because the loss of abdominal wall integrity exposes the patient to a high risk of evisceration, where abdominal contents protrude through the wound. This is a surgical emergency that demands covering the wound with sterile, saline-moistened dressings and immediate notification of the surgeon. Why the Other Options Are Less Immediately Critical While all the other options represent abnormal findings that require nursing action, they do not signal the same level of immediate, life-threatening urgency as a dehisced wound. Option 1: Serosanguineous drainage with mild erythema is a classic picture of a normal inflammatory phase of healing. A small amount of serosanguineous fluid is expected as part of the tissue exudate, and mild erythema confined to the incision edges is a normal response to the trauma of surgery and suture material. This finding requires continued monitoring and documentation but not immediate escalation. Option 3: A small amount of purulent drainage with localized warmth is highly indicative of a surgical site infection (SSI). This is a significant complication that delays healing and can predispose the wound to dehiscence, as seen in the case report where a patient developed a surgical site infection and the wound dehisced on postoperative day five [1]. However, at this stage, the infection is described as localized. The appropriate immediate interventions would be to culture the drainage, notify the provider for possible antibiotic therapy, and implement wound care measures. It does not yet present the acute structural failure that defines dehiscence. Option 4: Moderate edema and a pain level of 6/10 are concerning and warrant a thorough assessment. Edema can be a sign of excessive inflammation, a developing seroma, or a hematoma. Increased pain can be an early indicator of infection or compartment-like pressure. While this finding requires pain management and investigation into the cause of the edema, it lacks the cardinal sign of wound edge separation that makes dehiscence the most urgent priority. The integrity of the wound closure is not yet visibly compromised. The Pathophysiology of Dehiscence and Clinical Implications The mechanism behind wound dehiscence is a disruption of the sutured fascial layers before sufficient healing has occurred. This can be triggered by excessive strain, such as coughing or vomiting, or by a wound infection that digests the collagen matrix and suture material. The case reports underscore that this complication is not merely a local wound problem but a systemic threat. One case describes how a failure of abdominal wall integrity, secondary to an eventration, led directly to an anastomotic dehiscence, demonstrating the critical structural role of the closed wound [2]. For you as a nurse, recognizing the "sudden" nature of the drainage and the "visible separation" is the clinical trigger for action. This is a "failure to rescue" scenario on the NCLEX-RN, where your ability to recognize a subtle change—a sudden gush of fluid—as the first sign of a catastrophic event is being tested. The immediate nursing priority is to prevent evisceration by keeping the patient in a low Fowler's position with knees bent to reduce abdominal tension, covering the wound with a sterile saline dressing to keep the organs moist, and preparing the patient for an emergency return to the operating room. ## 임상 시나리오 Clinical Guide: Recognizing Acute Wound Dehiscence Postoperative Day 5 Assessment Priority Pathophysiology During the proliferative phase (day 4–21), collagen synthesis and angiogenesis occur, but wound tensile strength remains critically low. A sudden increase in mechanical stress or underlying infection can cause the fascial and skin layers to separate, leading to dehiscence. The serosanguineous fluid observed is often peritoneal or interstitial fluid leaking through the disrupted suture line. Key Assessment Findings - **Sudden increase in drainage:** A hallmark sign of mechanical suture line failure, not a gradual infectious process. - **Visible separation of wound edges:** Indicates fascial disruption; often described as a “gaping” wound. - **Patient report of a “popping” sensation:** May precede visible dehiscence and should be treated as an emergency. Immediate Nursing Actions - Stay with the patient and call for help; activate the rapid response team if available. - Cover the wound with sterile, saline-moistened gauze to protect exposed tissue. - Monitor for signs of evisceration (protruding organs); if present, do not reinsert organs and keep them moist with sterile saline. - Position the patient supine with knees slightly flexed to reduce abdominal wall tension. - Prepare the patient for emergency surgical repair and maintain NPO status. Differential Diagnosis Differentiate from wound infection, which presents with purulent drainage, localized warmth, and gradual onset. Dehiscence is characterized by a sudden change in drainage volume and visible separation. Infection can predispose to dehiscence, but the immediate threat is the loss of abdominal wall integrity. ## 핵심 개념 - **Wound Dehiscence** — Partial or complete separation of wound edges, often occurring 5-8 days postoperatively when suture strength is low; a surgical emergency. - **Serosanguineous Drainage** — Thin, pink-tinged fluid composed of serum and blood; a sudden increase may indicate fascial disruption and leaking tissue fluid. - **Proliferative Phase** — The second stage of wound healing (day 4-21) involving collagen deposition and angiogenesis, where wound tensile strength is still minimal. - **Evisceration** — Protrusion of abdominal organs through a dehisced wound, a life-threatening progression of wound dehiscence requiring immediate sterile coverage. - **Purulent Drainage** — Thick, yellow-green fluid containing leukocytes and bacteria, typically indicating a wound infection rather than acute mechanical failure. ## 같은 주제 문제 - [A nurse is assessing a postoperative patient's surgical wound on the second day after abdo…](https://mymerci.kr/pages/nclex_q.php?qn_id=542713) - [A nurse is preparing to change a sterile dressing on a postoperative chest wound.
