Debbie Codding, RN, BSN Oak Harbor, WA >> Debbie, Remember my post about the baby with citrulinemia? When the body cannot process the amino acid, argenine, the ammonia levels become toxic. It's a metabolic disease like PKU. The baby I worked with had an ammonia level in the 400's when he was hospitalized with seizures. We have a neo here who did research on this condition at the University of FLorida (I believe). Please e-mail me if you want more information. This baby presented with "poor feeding", spitting up and his mother had TONS of milk and a forceful letdown. They did a barium swallow at 3-4 days of age. He was jaundiced, finally lethargic and not eating when they sent him for a bili -he seized at the hospital. This baby was in ICU for some time and does obviously have some residual deficits. He is was maintained on carefully calculated EBM and a medication that helps with digestion of protein. Liz Flight, RN, CLE, IBCLC
