NEC this is what the doctor's diagnosed Derek with at 1 week old on August 21,2010
Dr.William McCarren called and told me over the phone that he was sick with this and we needed to come in and discuss more..he was a very sick little boy,I was afraid of what lied ahead.
*NOTE PICTURES*
#1 Derek,before they found NEC-looks great for 2lbs 11oz & 10 weeks early!(always trying to pull something out,notice the finger grabbing the nose canula)
#2 Is Derek,right after they diagnosed him with NEC,receiving a blood transfusion-1 of what would be 15 transfusions,during the course of his stay!(notice the dark red in color tube,that he is holding, running into the IV in his head..thats the transfusion)
#3&4 This is Derek,the week after they diagnosed him with NEC he was 3 weeks old..I was allowed to pick him up and carry him to the transport bed..I got emotional,this was a BIG day! (Notice how bloated/swallon he was..every pic still makes me cry.)
What is NEC you ask?
Necrotizing enterocolitis (NEC) is one of them. "Necrotizing" means the death of tissue, "entero" refers to the small intestine, "colo" to the large intestine, and "itis" means inflammation. But knowing what the words mean is only the start of understanding this infant disease.
A gastrointestinal disease that mostly affects premature infants, NEC involves infection and inflammation that causes destruction of the bowel (intestine) or part of the bowel. Although it affects only 1 in 2,000 to 4,000 births, or between 1% and 5% of neonatal intensive care unit (NICU) admissions, NEC is the most common and serious gastrointestinal disorder among hospitalized preterm infants.
NEC usually occurs within the first 2 weeks of life, usually after milk feeding has begun (at first, feedings are usually given through a tube that goes directly to the baby's stomach). About 10% of babies weighing less than 3 lbs.-5 oz. (1,500 grams) experience NEC. These premature infants have immature bowels, which are sensitive to changes in blood flow and prone to infection. They may have difficulty with blood and oxygen circulation and digestion, which increases their chances of developing NEC.
Causes
The exact cause of NEC is unknown, but one theory is that the intestinal tissues of premature infants are weakened by too little oxygen or blood flow. So when feedings are started, the added stress of food moving through the intestine allows bacteria normally found in the intestine to invade and damage the wall of the intestinal tissues. The damage may affect only a short segment of the intestine or can progress quickly to involve a much larger portion.
The infant is unable to continue feedings and starts to appear ill if bacteria continue to spread through the wall of the intestines and sometimes into the bloodstream. He or she may also develop imbalances in the minerals in the blood.
In severe cases of NEC, a hole (perforation) may develop in the intestine, allowing bacteria to leak into the abdomen and cause life-threatening infection (peritonitis). Because the infant's body systems are immature, even with quick treatment for NEC there may be serious complications.
Other factors seem to increase the risk of developing NEC. Some experts believe that the makeup of infant formula, the rate of delivery of the formula, or the immaturity of the mucous membranes in the intestines can cause NEC. (Babies who are fed breast milk can also develop NEC, but their risk is lower.)
Another theory is that babies born through difficult deliveries with lowered oxygen levels can develop NEC. When there isn't enough oxygen, the body sends the available oxygen and blood to vital organs instead of the gastrointestinal tract, and NEC can result.Babies with an increased number of red blood cells (polycythemia) in circulation also seem to be at higher risk for NEC. Too many red blood cells thicken the blood and hinder the transport of oxygen to the intestines.
NEC sometimes seems to occur in "epidemics," affecting several infants in the same nursery. Although this may be due to coincidence, it suggests the possibility that it could in some cases be spread from one baby to another, despite the fact that all nurseries have very strict precautions to prevent the spread of infection
Signs and Symptoms-(Derek had all these symptoms)
The symptoms of NEC can resemble those of other digestive conditions, and may vary from infant to infant. Common symptoms include:
•poor tolerance to feedings
•feedings stay in stomach longer than expected
•decreased bowel sounds
•abdominal distension (bloating) and tenderness
•greenish (bile-colored) vomit
•redness of the abdomen
•increase in stools, or lack of stools
•bloody stools
More subtle signs of NEC might include apnea (periodic stoppage of breathing), bradycardia (slowed heart rate)lethargy, and fluctuating body temperature. Advanced cases may show fluid in the peritoneal (abdominal) cavity, peritonitis (infection of the membrane lining the abdomen).
Diagnosis and Treatment-
The diagnosis of NEC is usually confirmed by the presence of an abnormal gas pattern as seen on an X-ray. This is indicated by a "bubbly" appearance of gas in the walls of the intestine, large veins of the liver, or the presence of air outside of the intestines in the abdominal cavity. A surgeon may insert a needle into the abdominal cavity to withdraw fluid to determine whether there is a hole in the intestines.
Most infants with NEC are treated medically, and symptoms end without the need for surgery. Treatment includes:
•stopping feedings
•nasogastric drainage (inserting a tube through the nasal passages down to the stomach to remove air and fluid from the stomach and intestine)
•intravenous (IV) fluids for fluid replacement and nutrition
•antibiotics for infection
•frequent examinations and X-rays of the abdomen
The baby's belly size is measured and watched carefully, and periodic blood samples are taken to look for bacteria. Stools are also checked for blood. If the abdomen is so swollen that it interferes with breathing, extra oxygen or mechanically assisted breathing (a ventilator) is used to help the baby breathe.
A baby who responds favorably may be back on regular feedings within 72 hours, although in most cases feedings are withheld and antibiotics are continued for 7 to 10 days. If the bowel perforates (tears) or the condition worsens, surgery may be indicated.
(THIS HAPPENED IN DEREK'S CASE)Severe cases of NEC may require removal of a segment of intestine. Sometimes after removal of diseased bowel, the healthy areas can be sewn back together. Other times, especially if the baby is very ill or there is spillage of stool in the abdomen, the surgeon will bring an area of the intestine or bowel to an opening on the abdomen (called an ostomy).
Most infants who develop NEC recover fully and do not have further feeding problems. In some cases, scarring and narrowing of the bowel may occur and can cause future intestinal obstruction or blockage.
Another residual problem may be malabsorption (the inability of the bowel to absorb nutrients normally). This is more common in children who required surgery for NEC and had part of their intestine removed.
