Understanding the Emergency
The scenario describes
wound evisceration — a full-thickness separation of the surgical incision with protrusion of abdominal contents, in this case loops of bowel. This is a surgical emergency distinct from simple dehiscence, because the exposed bowel is at immediate risk for
desiccation,
contamination, and
vascular compromise. The coughing spell on the sixth postoperative day is a classic precipitating event, as a sudden rise in intra-abdominal pressure stresses a healing but still fragile fascial closure .
The immediate nursing priorities are to reduce tension on the abdominal wall and protect the exposed viscera from drying and infection until surgical repair can be arranged. The patient is kept
NPO because emergency laparotomy under general anesthesia is anticipated .
Positioning: Why Low Fowler’s with Knees Flexed
The correct position is
low Fowler’s with the
knees flexed. This position serves two biomechanical purposes. First, flexing the hips and knees
relaxes the rectus abdominis and other anterior abdominal wall muscles, reducing tension on the separated fascial edges. Second, the slight head elevation of low Fowler’s (approximately 15–30 degrees) is more comfortable and physiologically tolerable than flat supine while still avoiding the increased intra-abdominal pressure that would occur in high Fowler’s position. High Fowler’s would pull the abdominal wall taut and could worsen protrusion of the bowel.
| Position | Effect on Abdominal Wall | Appropriateness in Evisceration |
|---|
| Flat supine, legs straight | Moderate baseline tension; no muscle relaxation from hip flexion | Less effective than knees-flexed position |
| Low Fowler’s, knees flexed | Reduced tension via hip/knee flexion; minimal intra-abdominal pressure increase | Optimal |
| High Fowler’s, legs straight | Increased intra-abdominal pressure; abdominal wall stretched | Contraindicated |
Watch out! Do not attempt to reinsert the bowel into the abdominal cavity. This is outside nursing scope and can introduce bacteria, cause trauma to friable bowel, or trap ischemic loops.
Wound Covering: Saline-Moistened Sterile Dressing
The exposed bowel must be covered with a
sterile dressing moistened with sterile normal saline. The moisture serves a critical protective function:
it prevents the serosal surface of the bowel from drying out, which would lead to tissue necrosis, adhesion formation, and increased risk of perforation. A dry gauze dressing would adhere to the delicate bowel wall and cause mechanical injury when removed, and it offers no protection against desiccation.
The dressing should be applied loosely, without pressure, and kept moist until the surgical team assumes care. Sterile technique is essential because the peritoneal cavity is now open to the environment, creating a direct portal for bacterial contamination and peritonitis .
Clinical Correlation with the Evidence
Case reports consistently describe evisceration as occurring after a sudden increase in intra-abdominal pressure — coughing, straining, or other Valsalva-type maneuvers — typically between the fifth and tenth postoperative day, when sutures may be intact but fascial healing is still incomplete . The presence of comorbid conditions that impair wound healing, such as diabetes mellitus, chronic obstructive pulmonary disease, or hypertension, increases the risk of fascial dehiscence progressing to evisceration . In the scenario, the patient’s coughing spell is the immediate trigger, and the nurse’s role is to stabilize the situation while summoning surgical assistance.
Key point! The combination of low Fowler’s position with knees flexed and a saline-moistened sterile dressing addresses the two immediate threats: mechanical tension on the wound and desiccation of the exposed bowel. Both interventions are performed while the patient remains NPO and the surgeon is notified for emergency operative repair .
