## 문제

A premature infant in the NICU, born at 28 weeks gestation weighing 1,200 grams 10 days ago and receiving enteral feedings, has been diagnosed with necrotizing enterocolitis (NEC) presenting with feeding intolerance, abdominal distension, and bloody stools. Which nursing intervention should be the priority?

A 28-week gestational age infant weighing 1,200 grams was born 10 days ago and has been receiving enteral feedings. The infant now presents with feeding intolerance, abdominal distension, and bloody stools.

1. Discontinue all enteral feedings immediately and maintain NPO status **✔ 정답**
2. Reduce the feeding volume by 50% and monitor for improvement
3. Switch from breast milk to specialized preterm formula
4. Increase feeding frequency while decreasing individual feeding volumes

**정답: 1**

## 해설

Immediate cessation of enteral feedings (NPO) is critical to prevent further intestinal damage and perforation in NEC. Other options may worsen the condition by continuing feedings.

Clinical Context

The scenario describes a 28-week preterm infant with a birth weight of 1,200 grams who is 10 days old and has been receiving enteral feedings. The classic triad of necrotizing enterocolitis (NEC) is now present: feeding intolerance, abdominal distension, and bloody stools. NEC is an acquired condition involving ischemic necrosis of the intestinal mucosa and represents the most common gastrointestinal emergency in the neonatal period [2]. The disease is particularly devastating in preterm infants, with high morbidity and mortality, and is known to cause highly severe and prolonged pain [1][3].

Priority Intervention Analysis

The correct answer is to discontinue all enteral feedings immediately and maintain NPO status. This is the foundational, non-negotiable first step in the acute management of NEC. The pathophysiology of NEC involves a complex interplay of intestinal ischemia, bacterial colonization, and formula or breast milk substrate in the gut lumen. Continued delivery of enteral nutrition provides a metabolic substrate for gas-forming bacteria, which exacerbates intestinal distension, intramural air (pneumatosis intestinalis), and the inflammatory cascade that drives mucosal necrosis [3]. By stopping all feedings, the nurse immediately removes the ongoing luminal insult, allowing for bowel rest—a critical component of medical management aimed at halting disease progression.

The other options are contraindicated in the acute presentation of NEC. Reducing feeding volume by 50% (Option 2) or manipulating feeding frequency and volume (Option 4) fails to achieve complete bowel rest and perpetuates the inflammatory process. Switching to a specialized preterm formula (Option 3) is inappropriate because any enteral substrate, regardless of type, will worsen the condition during the acute phase. The priority is complete cessation, not modification, of enteral intake.

Clinical Staging and Nursing Implications

Management of NEC is guided by Bell’s staging criteria, which classifies severity based on clinical and radiographic manifestations [3]. The infant’s presentation with bloody stools and abdominal distension corresponds to Bell’s Stage II (definite NEC). Medical management at this stage is intensive and includes NPO status, nasogastric decompression, broad-spectrum intravenous antibiotics, and serial abdominal examinations. The nurse’s immediate priority is to halt the disease process by discontinuing feedings, which also facilitates gastric decompression and reduces the risk of perforation. Pain management is another critical, though secondary, nursing consideration, as NEC is likely the most painful intestinal disease affecting preterm infants, and uncontrolled pain is associated with adverse short- and long-term outcomes [1]. However, the foundational intervention that must precede all other therapies is the immediate cessation of enteral feedings.References (research sources)

NEC Acute Management: Priority Nursing InterventionImmediate Cessation of Enteral Feedings
Upon recognizing the classic NEC triad (feeding intolerance, abdominal distension, bloody stools), the priority is to discontinue all enteral feedings and maintain NPO status.

This intervention provides bowel rest by removing the luminal substrate (milk/formula) that gas-forming bacteria metabolize, which exacerbates pneumatosis intestinalis and the inflammatory cascade driving mucosal necrosis.

CautionDo not attempt to simply reduce the volume or change the formula type. Any enteral intake during the acute phase is contraindicated. Decompression via an orogastric tube and initiation of IV fluids/antibiotics are concurrent next steps after making the patient NPO.

- **Necrotizing Enterocolitis (NEC)** — An acquired neonatal gastrointestinal emergency involving ischemic necrosis of the intestinal mucosa, commonly presenting with the triad of feeding intolerance, abdominal distension, and bloody stools.
- **NPO (Nil Per Os)** — A medical order meaning nothing by mouth; in NEC, it is the immediate intervention to provide complete bowel rest and remove luminal substrate for bacteria.
- **Pneumatosis Intestinalis** — The presence of gas within the bowel wall, a hallmark radiographic finding in advanced NEC resulting from gas-forming bacteria.
- **Bowel Rest** — A critical management strategy for NEC involving cessation of all enteral feedings to reduce metabolic demand, inflammation, and bacterial fermentation.
