Neonatal Case Study Presented by: Mikaela Hew MS CN June 11, 2013 UCSD Dietetic Internship 2012-2013
Outline and Objectives • Neonatal patient population • Normal digestive tract/abdominal wall development • What is Gastroschisis? • Case study patient, medical course, complications, labs, growth charts, medications, summary of feeding • Cholestasis of parenteral nutrition • Case study nutrition care process (estimated needs, diagnosis, monitoring and evaluation) • Prognosis/Conclusion
Introduction Gestational age • Preterm <37 weeks gestation • Term 37-42 weeks gestation • Post Term >42 weeks gestation Birth weight • Low birth weight (LBW) <2,500g • Very low birth weight (VLBW) <1,500g • Extremely low birth weight (ELBW) <1,000g Gastrointestinal and abdominal wall development
Gastroschisis: Definition Structural defect, or “hole” in the abdominal wall in which abdominal organs go out of the abdomen to the exterior of the body.
Gastroschisis: Pathophysiology and diagnosis PATHOPHYSIOLOGY • Defective development of mesenchyme in abdominal wall • Involution of the umbilical vein causing weakness or rupture DIAGNOSIS • Prenatal ultrasound 14 weeks after conception • Maternal Serum Alpha Fetoprotein (MSAFP)
Gastroschisis: Complications and Treatment COMPLICATIONS • Amniotic fluid exposureinterferes with normal development • Atresia • Hypothermia, dehydration, sepsis, hypoglycemia • Prolonged feeding problems, slow weight gain • Need for parenteral nutrition TREATMENT • Surgery: necrotic segments, reduction of the bowel, gastrostomy, ileostomy, jejunostomy • SILO placement: protective covering for organs until the bowel is slowly reduced (by hand) back into the abdominal cavity.
Gastroschisis: Patient Outcomes • Normal development, slow growth (Minnesota Neonatologists Study) • Need for prolonged parenteral nutrition • Depending on how much bowel is left, possible short gut/bowel syndrome • Intestinal dysmotility • Malabsorption from mucosal injury • Gastroesophageal reflux DIETARY MANAGEMENT
Case Study Patient “BB” is a baby boy, born at 34 weeks, 4 days • Weight: 2064g (37th%) Length: 45cm (56th%) Head Circumference:31cm (50th%) Mother 20 y/o G2P0111 • G2: pregnant twice • P0: did not carry any to full-term • P01: had one pre-term • P011: had one abortion (or spontaneous abortion/miscarriage) • P0111: one is living BB with no spontaneous cry, floppy. Radiant warmer, plastic bag, positive pressure ventilation, intubation and transfer to Neonatal Intensive Care Unit at 17 minutes of life. Born w/ Congenital Gastroschisis: necrosis, ischemia and perforation
APGAR Scores Quick test performed at 1 and 5 minutes after birth. • 1 minute: how well the baby tolerated the birthing process • 5 minutes: how well the baby is doing outside the mother’s womb Score out of 10 BB’s APGAR Scores: • 1 minute: 2 • 5 minutes: 8 (-1 color, -1 respiratory effort)
Infant Growth: Weight Normal for a preterm infant to lose weight after birth (≤15%) Birth weight should be regained by two weeks of life BB trends upward between the 10th-50th%tile
Infant Growth: Length Desired length of a preterm infant is about 0.8-1.1cm/week. For BB, now about 0.6-0.8cm/week at term. Length more accurately reflects lean body mass and is not influenced by fluid status. BB’s length experienced a few distinct drops in measurement, but is now trending back up along the 50th%tile.
Infant Growth: Head Circumference Normal for an infant to lose head circumference during the first postnatal week by approximately 0.5cm. Catch-up growth: 0.5cm/wk between birth and 3months. BB’s head circumference has grown steady from March to date >50th%tile.
Vitamin Supplementation FAT SOLUBLE VITAMINS: • Vitamin A: If premature, lower liver stores, lower serum retinol values • Vitamin E: If preterm, low body stores. Supplementation varies depending on formula feeders, receiving therapeutic iron • Vitamin D: If preterm, limited reserves. If on PN, may have adequate serum levels (most often supplied adequately in parenteral nutrition) OTHER VITAMINS: • Vitamin K: endogenous production impaired by long term parenteral nutrition or antibiotic usage • Multivitamin may be warranted in low volume feedings
Mineral Supplementation ELECTROLYTES • Sodium and potassium: excreted quickly during first 10-14 days in preterm infants. • Magnesium, calcium, phosphorus are all accrued during the last trimester of pregnancy. IRON • Lower in preterm infant than term infant • Supplementation not indicated during first 2 weeks of life TRACE MINERALS • Zinc for breastfed infants • Copper affected by dietary zinc
Nutritionally related medications/supplements • At birth: Plasmalyte A IV bolus 21mL and 1,000mL infusion (water, electrolytes and 21kcal/L) NaCl26mL, Vitamin K 1mg, Dextrose 10% • AQUADEKS 0.5mL 4/24-5/15 (likely supplemented in suspicion of malabsorption) • Cholecalciferol400units 4/8-4/26 and 4/28-5/15 and 5/26-5/30 and 6/4-6/6 • Epoetin Alfa 300units/kg 4/14-4/23 • Pepcid 4/7-4/7 • Prevacid4/19-5/11 and 5/25-5/30 and 6/4 to current • Ferrous Sulfate 6.9 mg 4/14-4/25 (increased while on epoetinalfa) • Ferrous Sulfate 4.65mg 4/25-4/26 and 4/28-5/11 (decreased once patient started on small enteral feeds) • Ferrous Sulfate 5.4mg 5/11-5/15 • Ferrous Sulfate 11.5mg 5/29-5/30 • Fish Oil/DHA 100mg/mL 4/14-4/26 • Actigall 15mg/kg 4/17-5/15 • NaClinfusions since birth • Na Acetate in TPN since birth • Trace elements in TPN since birth • Pediatric multivitamin in TPN since birth
Summary of Feeding (See Handout) • Bowel unable to be utilized due to Gastroschisis, areas of necrosis and ischemiaTotal Parenteral Nutrition • Glucose infusion rate range: 8.8-15.6mg/kg/min • MBM used for 3 monthsPregestimilNeocate via Nipple and Gavage • Persistently elevated direct bilirubin • IL lowered 1/18 from 2.5 to 2g/kg • IL lowered 4/27 from 3 to 2.5g/kg • IL lowered 5/21 from 2.5 to 1g/kg • History of high output to ostomy with distal re-feeds. • Late March: 26-49.6mL/kg/d • 4/29-5/4: 23-62/mL/kg/d • Fish oil stopped 4/26 • Frequent NPO for procedures/tests, ostomy output • TPN has been providing 100% of estimated nutrition needs up until 2 weeks ago
Cholestasis of Parenteral Nutrition • Diagnosed 2/11, approximately 1 month after birth • Common problem in the NICU • Causes: • Long term dependence on TPN • Prematurity • Spontaneous ileal perforation • Gastroschisis • Multiple gastrointestinal surgical procedures
Cholestasis of Parenteral Nutrition • Pathophysiology for elevated Direct Bilirubin: • Impaired hepatic bile flow • Immature organ development including adynamic gallbladder (bowel disuse) • Upsurge in release of direct bilirubin as infant matures • Direct liver damage resulting from TPN • Pathophysiology for high Alkaline Phosphatase • Damaged liver which regurgitates hepatic alkaline phosphatase back into the serum • Impaired biliary excretion of the enzyme
Cholestasis of Parenteral Nutrition Medical Nutrition Therapy • Discontinuation of TPN with advancements of enteral feeding • Cyclic TPN • Decreased doses of lipid infusion • Fish oil based IV fat emulsions, or oral supplementation (Texas Children’s Hospital)
Estimated Nutrition Needs Total Fluids: 150-200mL/kg/d 110-120 kcal/kg/d 3-4 g/kg Protein Re-estimated nutrition needs (3/26)Total Fluids 150-200mL/kg/d120-130 kcal/kg/d3-4 g/kg Protein
Diagnosis/Monitoring and Evaluation Nutrition Diagnosis (PES): Patient w/ altered GI function r/t Gastroschisis AEB Parenteral Nutrition Monitoring/Evaluation: • Continue gaining weight at approximately 30g/d • Advance from TPN to enteral feeding as medically able • Monitor GIR and trend direct bilirubin • Monitor weight changes, GI status/availability for enteral feeding, feeding progression, pertinent lab values.
Conclusion • BB is now 145 days old • Prognosis for Gastroschisis promising and the neonatologists have noted overall improvements in BB’s bowel health/healing. • BB continues to have difficulty with po feeding requiring TPN • Recently large bilious residuals and emesis (indicative of intolerance) • Oral aversion w/ NG placement for enteral feeding • Long term TPN in setting of poor po can continue to compromise organ function and increase the risk of metabolic bone disease.
