  • 1. NECROTIZING ENTEROCOLITIS (NEC):IS A GASTROINTESTINAL DISEASE THAT IS FOUNDPRIMARILY IN PREMATURE INFANTS, ALTHOUGH ITCAN OCCUR IN FULL-TERM INFANTS AS WELL. ANINFECTION OR INFLAMMATION CAUSES THEDESTRUCTION OF ALL OR PART OF THE BOWEL (SMALLINTESTINE) OF THE BABY. THIS IS A SERIOUSCONDITION THAT REQUIRES CARE FROM YOUR BABYSDOCTOR. ALMOST ALL BABIES AT RISK FOR NEC AREALREADY HOSPITALIZED IN A NEONATAL INTENSIVECARE UNIT (NICU) AND UNDER CLOSE OBSERVATIONDUE TO THEIR SMALL SIZE.MOST COMMON GASTROINTESTINAL MEDICALAND/OR SURGICAL EMERGENCY OCCURRING INNEONATES
  • 2. CAUSES:No exact cause is known for NEC. The bowel and intestine of a prematurebaby is not fully developed, and may not be able to handle the stressof food moving through them. A decrease in oxygen or blood flow to theintestines may cause damage, allowing bacteria to enter through thewall , leading to infection and inflammation. This can damage thestrength of the intestinal tissue. If the bacteria remain long enough,they can make a hole in the wall of the intestine.NEC is most often found in premature, very low-birthweight babies.NEC usually occurs in the first two weeks of life, but can occur aslate as three months of age.NEC usually occurs soon after you have started feeding your baby.
  • 3.  CLINICAL FEATURES: If your baby experiences any of these symptoms, do not assume it is due to NEC. The symptoms of NEC are very similar to other, less serious, digestive conditions. Every baby experiences the symptoms of NEC differently. The symptoms may include: Difficulty feeding Feedings stay in babys stomach longer than expected A sudden increase in bowel movements, or lack of bowel movements Bowel movements may be bloody Baby doesnt pass a lot of gas Babys belly may be bloated, tender to the touch, or red Vomit may be greenish in color Baby shows general signs of infection, such as:
  • 4.  Initial symptoms may be subtle and can include the following  Feeding intolerance  Delayed gastric emptying  Abdominal distention and/or tenderness  Ileus/decreased bowel soundsStopping breathing or difficulty breathing  Low heart rate  Sluggishness  Vomiting  Temperature instability  Cool, clammy skin
  • 5. Incidence and age at onset:more common in premature infantsBut can also be seen in term babiesInversely related to birth weight and gestational ageTerm infants develop NEC earlier after birth than preemiesAverage age of onset occurs within first week of lifeAffected term neonates are usually systemically ill with otherconditions such as birth asphyxia, respiratory distress or congenitalheart diseasePremature babies are at risk for several weeks after birthBabies who are breastfed have a lower incidence of NEC than formula-fed babiesMor

  • 7.  How is NEC managed? Medical management consists of stopping feeds, nasogastric drainage to suction (tube in baby’s stomach to "suck out" contents), 7- 14 days of antibiotics and IV nutrition. Close monitoring of fluid status, electrolytes, coagulation and oxygen requirements are also necessary. 60-80% of babies with NEC are managed medically and symptoms resolve without surgery. Feedings postoperatively are started slowly.
  • 8.  What if surgery is needed? Surgery is necessary if medical management fails or the bowel is perforated (torn). After opening the abdomen, the surgeon may find a swollen, purple bowel with areas of necrosed(dead) bowel. The usual areas involved are the terminal ileum, Cecum and right colon but the whole bowel may be involved. The goal is to remove only that bowel that is fully necrosed(dead) and to leave any marginal areas in the hope that they will survive. This may require an ostomy and/or another operation within 24-48 hours to evaluate any surviving bowel. The nutritional outcome is roughly based on the remaining intestinal length and the medical and surgical team will discuss this with you.
