A 71-year-old man is evaluated on the surgical ward immediately after experiencing a sudden "tearing" sensation in his abdomen during a severe bout of coughing. He is on postoperative day 6 following an open sigmoid resection for complicated diverticulitis. His temperature is (), blood pressure is , and pulse is . When the abdominal binder and surgical dressings are removed, a large volume of serosanguineous fluid is noted, and loops of small intestine are visibly protruding through the separated midline fascial defect.
Arrange the following next steps in the most appropriate chronological sequence for managing this patient's acute complication.
- 1Position the patient supine with hips and knees flexed
- 2Cover the protruding viscera with sterile, saline-moistened dressings
- 3Establish intravenous access for fluid resuscitation and broad-spectrum antibiotics
- 4Transport the patient to the operating room for emergent surgical exploration and closure
Answer
The correct sequence for managing abdominal evisceration is to first reduce abdominal tension by positioning the patient supine with flexed knees, followed by protecting the exposed bowel with moist sterile dressings, then initiating medical preparation with intravenous fluids and antibiotics, and finally transporting the patient to the operating room for definitive surgical closure.
Abdominal evisceration is a surgical emergency characterized by disruption of all layers of the abdominal wall with protrusion of intra-abdominal organs, often triggered by a sudden increase in intra-abdominal pressure (e.g., severe coughing). The most critical immediate goal is to prevent further evisceration and bowel ischemia. Positioning the patient supine with hips and knees flexed relaxes the abdominal musculature and reduces intra-abdominal pressure. Next, the exposed bowel must be covered with sterile, warm, saline-moistened dressings to prevent tissue desiccation and necrosis. Once the bowel is protected, the patient is hemodynamically stabilized and prepped with intravenous fluids and broad-spectrum antibiotics. Finally, the patient must be urgently transported to the operating room for formal surgical exploration, peritoneal washout, and fascial closure.
