A nurse is assessing a surgical wound on postoperative day 5. Which finding would indicate the most concerning complication requiring immediate intervention?

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.

• 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.

1. Stay with the patient and call for help; activate the rapid response team if available.
2. Cover the wound with sterile, saline-moistened gauze to protect exposed tissue.
3. Monitor for signs of evisceration (protruding organs); if present, do not reinsert organs and keep them moist with sterile saline.
4. Position the patient supine with knees slightly flexed to reduce abdominal wall tension.
5. Prepare the patient for emergency surgical repair and maintain NPO status.

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.
