CLIPP 01: Newborn evaluation Flashcards
How can smoking during pregnancy affect the fetus?
Maternal tobacco use during pregnancy increases the risk for low birth weight in the fetus.
How does cocaine and other stimulant use affect pregnancy?
These cause vasoconstriction leading to placental insufficiency and low birth weight.
How can heroin and other opiates affect pregnancy?
Maternal heroin use is associated with increased risk of fetal growth restriction, placental abruption, fetal death, preterm labor and intrauterine passage of meconium.
How to treat healthy vs ill appearing infants born to GBS positive mothers not prophylaxed with amp
Healthy: CBC and blood culture
Ill-appearing: CBC, blood culture, chest xray and lumbar puncture
What does APGAR stand for?
A- appearance P- pulse G- grimace (reflex ability) A- activity (muscle tone) R- respirations
How to we follow APGAR scores?
a score below 7 at 5 minutes should prompt continued resuscitation, with re-assessment every 5 minutes, up to 20 minutes, until a score of 7 is achieved
How do apgar scores predict mortality?
The Apgar score does not identify birth asphyxia and does not predict individual neurologic outcome or mortality
What defines an SGA neonate?
Small for gestational age (SGA) = Weight below the 10th percentile for gestational age
What determines a term baby?
Term = Born at > 37 weeks’ gestation
Describe asymmetric intrauterine growth restriction
Asymmetric IUGR refers to a greater decrease in the size of the length and/or weight without affecting head circumference (“head-sparing phenomenon”). Poor delivery of nutrition to the fetus (example maternal smoking) often results in asymmetric IUGR
List three additional risks associated with SGA babies
Polycythemia- due to chronic hypoxia
Hypothermia- due to cold stress, hypoxia, hypoglycemia, increased surface area and decreased subq insulation
Causes of an absent red reflex?
A cataract An opacified cornea (such as in mucopolysaccharidosis) Inflammation of the anterior chamber Developmental anomalies of the eye Retinoblastoma
Three meds administered at birth?
Erythromycin
Hep B vaccine
Vitamin K
infants born to mothers who are positive for HepB surface antigen should be treated how? How effective are these interventions?
Should receive the hepatitis B vaccine as well as hepatitis B immune globulin (HBIG) within 12 hours of delivery
Vertical transmission can be prevented in 85-95% of cases using these interventions
What is the weight cut off for administering hepB vaccine?
2kg
What interventions should be administered to neonates to mothers with unknown HepBAg status?
Administration of HBIG can be delayed until the maternal HBsAg is known, and is effective if given within 7 days following delivery if the patient is greater than 2 kg at birth
What does erythromycin in the eyes prevent?
gonococcal conjunctivitis
Chlamydia trachomatis conjunctivitis in newborns is more common than gonococcal, but chlamydia typically occurs at 7-14 days after birth, and neonatal prophylaxis does little to prevent chlamydia conjunctivitis
What are some of the risks of taking anticonvulsants during pregnancy?
Taking anticonvulsants during pregnancy may lead to cardiac defects, dysmorphic craniofacial features, hypoplastic nails and distal phalanges, IUGR, and microcephaly. Mental retardation may be seen. A rare neonatal side effect is methemoglobinuria
List a few causes of congenital heptosplenomegaly
Hepatosplenomegaly in newborns is seen in metabolic diseases, storage diseases, HIV vertical transmission, intrinsic liver disease, and in congenital infections
