1

associated with elevated AFP

RAIN
Renal (nephrosis, renal agenesis, polycystic kidney)
Abdominal wall defects
Incorrect dating/multiple gestation
Neuro (anencephaly, spina bifida)

2

associated with low AFP

chromosomal abnormalities (trisomy 18 or 21)

3

measures spontaneous fetal movement and heart rate activity

non stress test

4

measures autonomic nervous system integrity

non stress test (by measuring spontaneous fetal movement and HR activity)

5

measure uteroplacental insufficiency and tolerance of labor

contraction stress test (by measuring fetal HR in response to uterine contraction)

6

positive contraction stress test

late decelerations after 50% of contractions - requires further work up

7

biophysical profile

non stress test and US to evaluate: fetal movement, reactive HR, breathing, tone and volume of amniotic fluid

8

apnea

no breathing >20 seconds

9

apnea of prematurity treatment

caffeine and theophylline

10

how to help reverse primary apnea

tactile stimulation and blow by oxygen

11

how to help secondary apnea

PPV

12

pressure needed to inflate lungs with first breath

60 mm Hg

13

fluid in the interloper fissures and increased interstitial pulmonary markings in baby born by c-section

TTN

14

TTN typically resolves in

72 hours

15

hyaline membrane disease aka

RDS

16

granular opacification's and air bronchograms with a ground glass appearance obscuring heart and diaphragm borders on xray

RDS

17

granular opacification's and air bronchograms with a ground glass appearance obscuring heart and diaphragm borders on xray that is progressively worsening despite respiratory assistance

GBS pneumonia

18

testing to indicate low risk of RDS

lethicin:sphingomyelin ratio >2

19

mechanical ventilation indicated in RDS when pH and CO2 ___

pH <7.2 and pCO2>60

20

clinical improvements expected with giving surfactant in RDS

decrease O2 requirement, increased lung compliance and decreased inspiratory pressure

21

BPD treatment

diuretics

22

babies with BPD are at risk for

hypocalcemia 2/2 diuretic use

23

BPD is present in infants who

require oxygen past 28 days after birth and/or at 36 weeks corrected GA

24

diffuse opacities with cystic areas and streaky infiltrates and ground glass appearance in infant on xray

BPD

25

sepsis treatment in neonates

ampicillin and gentamicin (enterobacter and serratia are resistant to cefotaxime)

26

placenta with white nodules think

listeria

27

early onset GBS presents when

first 7 days of life

28

late onset GBS presents when

usually first month of life but can be up to 90 days

29

late late onset GBS presents when

up to 6 months in preemies

30

when to screen for GBS

35 to 37 weeks
