Abdominal Ultrasound Scanning for NEC in Babies at the Threshold of Viability
Topic overview
Study evaluating abdominal ultrasound for diagnosing NEC in extremely premature infants born <24 weeks gestation. AUSS findings (complex ascites, inflamed bowel, aperistaltic bowel) reliably identified surgical candidates, outperforming plain radiography in this vulnerable population.
Key takeaways
- Abdominal ultrasound reliably identifies surgical NEC in extremely preterm infants (<24 weeks) with atypical presentations.
- Complex ascites, inflamed bowel, and aperistaltic bowel on ultrasound correlate with surgical NEC requiring laparotomy.
- Plain radiographs often show only nonspecific findings (paucity of gas) in extremely preterm NEC cases.
- Simple free fluid or pneumatosis alone on ultrasound may indicate non-operative NEC management is appropriate.
- Ultrasound adds critical diagnostic value when clinical and radiographic findings are equivocal in micro-preemies.
