Definition of low blood sugar
|
blood glucose less than 45 mg/dL with smptoms
|
|
MC causes of hypoglycemia in newborn
|
diabetic mothers, IUGR, sepsis
|
|
Clinical presentation of hypoglycemia
|
lethargy, poor feeding, hypotonia, jitteriness, seizures
|
|
Tx for hypoglycemia in infants with BS 20-40 and no sxs
|
oral feeds and monitor with repeat testing
|
|
Tx for hypoglycemia in infants with BS 20-40 and symptoms or BS less than 20
|
Bolus 10W at 2 cc/kg then 6 mg/kg/min; treat undelrying cause if possible
|
|
MC cause of neonatal seixures
|
hypoglycemia
|
|
Common reversible causes of neonatal seizures
|
hypooglycemia, hypocalcemia, sepsis/encephalitis, kernicterus, and drug withdrawal
|
|
Common irreversibel causes of neonatal seizures
|
metabolic syndromes, familial seizures, ischemia
|
|
Clinical presentation of neonatal seizures
|
seizure often subtle and hard to diagnose; look for rhythmicity and patterns, EEGs to diagnose
|
|
What labs do you need to draw with acute seizure?
|
CBC, Chem &, Ca
|
|
2 causes of neonatal anemia
|
hemolytic disease of newborn and blood loss
|
|
MC cause of hemolytic disease of the newborn
|
ABO incompatibility
|
|
3 causes of hemolytic disease of the newborn
|
ABO incompatibility; Rh incompatibility, and other antigen Rh C, E, Kell, Duffy
|
|
What are the causes of birth related blood loss?
|
maternal-fetal hemorrhage, placenta previa, and cord rupture/ early cord clamping
|
|
How is iatrogenic blood loss caused in neonates?
|
repeat labs on NICU patients
|
|
Level of bilirubin in all newborns.
|
elevated
|
|
Jaundice
|
staining of skin due to breakdown of bili- doesn't really matter that the color is different, but that it leads to an undelrying process
|
|
Kernicterus
|
staining of brain similar to jaundice---> causes mental retardation
|
|
Reasoons why babies have elevated bilirubin
|
increased RBC mass and turnover, insufficient hepatic clearance, decreased gut motility and excretion
|
|
Types of bilirubin
|
pathologic (unconjugated and conjugated) and physiologic (breastfeeding jaundice and breast milk jaundice)
|
|
Why do babies get breastfeeding jaundice?
|
they may not get real food for 5-7 days so they will not poop a lot and then develop jaundice
|
|
Why do babies get breast milk jaundice?
|
After the milk supply is being produced, in some moms there is a free fatty acid that blocks the conjugation of bili in breastfeeding kids--> not really high enough to cause kernicterus
|
|
Unconjugated pathologic jaundice is caused by what two means?
|
hemolyis usually due to Abo/Rh isoimmunization OR insufficient conjugation
|
|
Rare profound jaundice as a result of insufficent conjugation
|
Crigler-Najjar
|
|
very common syndrome where molecule doesn't work quite fast enough to cause suffiicent conjugation--> usually not serious, runs in family
|
Gilbert's syndrome
|
|
Coonjugated jaundice is a result of what?
|
obstruction distal to liver
|
|
Factors that make jaundice more likely to be pathologic (kernicterus causing)
|
peak level over 15 mg/dl (kernicterus doesn't start here, but we want to prevent it)--> age dependent- if premie, may be as low as 7; nomogram rate of rise greater than 5 mg/dl per day; and onset within 24 hrs of life
|
|
Look for jaundice here
|
under tongue, sclera, scalp, then progresses head to toe(jaundice at belly button is at least 12)
|
|
Coomb's test
|
looking for maternal antibodies in blood
|
|
Peripheral smear purpose
|
look for broken RBCs
|
|
What groups do you do G6PD test in?
|
African, Asian, and Med. Male
|
|
Tx for jaundice
|
improve/increase feeding (do not stop breastfeeding); phototherapy; exchange transfusion
|
|
Severe gut dysfunction due to feeding a premature GI tract
|
necrotizing enterocolitis (ischemia not infectious)
|
|
Classic radiograph findings in necrotizing enterocolitis
|
pneumonia intestibalis (gas between the subserosal and muscularis layer of the small bowel wall) plus free air or ileus
|
|
Tx for necrotizing enterocolitis
|
stop feedings (start TPN), NG decompression, broad spectrum Abx, surgical excision in 50%
|
|
Classic presentation in necrotizing enterocolitis
|
feeding intolerable, abd. Distention, and rectal bleeding in premie (severe- DIC and shock)
|
