PROSPECTIVE APPLICATION OF AN INDEX OF NEONATAL NECROTIZING ENTEROCOLITIS

Fifty-five patients were scored 1 to 3 according to the criteria: the character of stools, abdominal findings on palpation, x-ray evidence of pneumatosis intestinalis, the development of pulmonary insufficiency, and the duration of symptoms to positive x-rays. Fifteen patients with scores of less than five were considered to have subclinical NEC with one late death. Twenty-nine of 30 patients with scores of 5-10 responded to medical management with 2 deaths related to recurrent bouts of sepsis without recurrent NEC. Eleven patients required surgery with index scores of 10-14 with 6 deaths occuring uniformly in those patients with scores of 12 or more. Two patients were scored inappropriately low due to the lack of the passage of a stool for analysis. One patient with a score of 4 did not pass a stool but had the other diagnostic criteria for the single false negative of the series. This index correctly determined the severity of NEC of 53 of 55 patients, identified the patients who required surgical intervention and predicted survival. © 1979 Grune & Stratton, Inc.
