A 12-month-old infant with confirmed intussusception is scheduled for a barium enema reduction procedure. The infant has been experiencing intermittent severe abdominal pain, vomiting, and has passed one stool containing blood and mucus. Which nursing intervention should be the priority?

Understanding the Clinical Scenario

This question presents a classic case of intussusception, a condition where a proximal segment of intestine telescopes into a distal segment, most commonly affecting the ileocolic region in children aged 6-18 months ^[2]. The hallmark "currant jelly stool" (blood and mucus) and intermittent severe pain are strong clinical indicators. The infant is scheduled for a barium enema reduction, which is both a diagnostic and therapeutic procedure. However, the critical nursing priority lies in anticipating the potential for clinical deterioration and treatment failure.

Analyzing the Priority Intervention

The correct answer is to maintain NPO status and prepare for potential surgical intervention. This is the priority because of the underlying risk of bowel ischemia and the unpredictable success of non-operative reduction.

• Pathophysiology of Risk: The telescoping bowel pulls its mesentery along with it, compressing venous and lymphatic return. This leads to edema, arterial compression, and ultimately bowel ischemia and necrosis if the obstruction is not relieved ^[2]. While a barium enema is the first-line treatment, it is not always successful. The procedure itself carries a risk of perforation, especially if necrosis is already present. Therefore, the patient must be surgically "ready" before the procedure begins.



• Why NPO is Non-Negotiable: The infant has been vomiting and has a bowel obstruction. Any oral intake will increase intraluminal pressure, worsen vomiting, and elevate the risk of aspiration. More critically, if the enema fails or perforation occurs, the patient will require an emergency surgical reduction. An empty stomach is essential for safe general anesthesia. Maintaining NPO status is the foundational safety measure that bridges the gap between a planned non-invasive procedure and an unplanned surgical emergency.



• Clinical Course and Treatment Outcomes: A study on treatment outcomes in a similar setting highlights that while non-operative management is the goal, a significant proportion of patients require surgical intervention. The clinical profile often includes delayed presentation, which increases the likelihood of failed enema reduction and the need for operative management . The nurse's role is to continuously monitor for signs of deterioration—such as worsening pain, abdominal distension, or shock—that signal failed reduction or perforation, necessitating immediate escalation to surgery.

Why Other Options Are Not the Priority

While the other interventions may seem appropriate for comfort or hydration, they are contraindicated or secondary in this acute scenario.

• Administering Pain Medication (Option 1): While analgesia is important, administering it before a clear surgical plan is established can mask the classic signs of peritonitis or perforation, which are critical for ongoing assessment. The immediate priority is ensuring the safety of the planned procedure and preparing for its most serious complications. Pain management is a subsequent step, not the first priority.



• Encouraging Oral Fluids (Option 2): This is contraindicated. The infant has a mechanical bowel obstruction and is vomiting. Giving oral fluids will not correct dehydration effectively and will dangerously increase the risk of aspiration, especially if sedation or emergency surgery is required.



• Applying Warm Compresses (Option 3): This provides minimal comfort and does not address the life-threatening pathophysiology. It is a non-urgent comfort measure that delays essential, potentially life-saving preparation. It does not mitigate the risk of aspiration or surgical delay.

The core nursing principle in this scenario is safety and anticipation of the worst-case scenario. Because the success of a barium enema is not guaranteed and the risk of perforation exists, the nurse must first ensure the patient is physically prepared for an emergency laparotomy by strictly maintaining NPO status [1,2]. The diagnostic accuracy of initial assessment tools like ultrasound is high, but the definitive management trajectory can shift rapidly, making surgical preparedness the immediate nursing priority .
