Feeding Intolerance or Early Necrotizing Enterocolitis?
A 27 3/7-week, 980-g infant is now 14 days old. She has been stable on high-flow nasal cannula at 3 L/min and receiving fortified human milk at 120 mL/kg/day by nasogastric tube. Over 12 hours she develops a tense, distended abdomen, greenish gastric residuals of 8 mL, temperature instability at 36.2°C, heart rate 172, blood pressure 45/25 mm Hg, capillary refill 4 seconds, and one bloody stool. Laboratory results: WBC 3.2 × 10^9/L, platelets 68 × 10^9/L, CRP 45 mg/L, pH 7.22, base deficit 8 mmol/L, lactate 3.8 mmol/L, glucose 45 mg/dL. Abdominal radiograph shows dilated loops and pneumatosis intestinalis in the right lower quadrant, without free air or portal venous gas. The surgical team recommends re-examination in 6 hours. The nurse is concerned about delay.
1. What are the immediate priorities, and should the nurse advocate for earlier surgical evaluation? Support your answer.

Immediate priorities: stop feeds, place the nasogastric tube to low intermittent suction, obtain blood cultures, start broad-spectrum antibiotics (ampicillin, gentamicin, and metronidazole per unit protocol), give a 10–20 mL/kg normal saline bolus for hypoperfusion, correct glucose 45 mg/dL, and obtain serial ABG, lactate, CBC, and platelets. Yes, advocate for earlier surgical evaluation. Pneumatosis plus thrombocytopenia, acidosis, and hypotension indicates Bell stage IIB or worse, not simple feeding intolerance. A 6-hour delay risks progression to perforation. Use the chain of command and state the objective findings: pneumatosis, lactate 3.8, platelets 68, base deficit 8, and bloody stool. Monitor: abdominal girth, skin color, urine output, and repeat abdominal radiograph in 6 hours or sooner if deterioration.
2. Which findings would mandate immediate return to surgery or bedside decompression, and how would you monitor?
Read the worked answer
Mandatory escalation: pneumoperitoneum, fixed dilated loop, portal venous gas, abdominal wall erythema or induration, bilious emesis, bloody stool with instability, rising lactate, worsening acidosis, increasing ventilator needs, hypotension, or oliguria. These suggest perforation or necrosis and need immediate surgical review, not a scheduled recheck. Nursing: serial abdominal examinations and girth measurements, strict intake and output, daily weight, pain assessment, avoidance of rectal temperatures and enemas, monitoring of platelet count and coagulation, and preparation for possible bedside decompression or laparotomy.
