at 1 and 5 minutes after birth
repeat at 10 minutes if abnormal
PPP 382
what is the first ‘A’ in APGAR?
Appearance
skin color changes
(PPP 382)
how do we grade the first ‘A’ in APGAR?
0 = blue-grey, pale all over
1 = acrocyanosis: body pink but blue extremities
2 = pink baby (no cyanosis)
(PPP 382)
what is the P in APGAR?
Pulse
(PPP 392)
how do we grade the P in APGAR?
0 = no pulse
1 = HR < 100
2 = HR >= 100
(PPP 382)
what is the G in APGAR?
Grimace
reflex irritability
(PPP 382)
how do we rate the G in APGAR?
0 = no response to stimulation, flaccid
1 = grimaces feebly, only w/ stim
2 = pulls away, sneezes or coughs, active motion, cries, coughs, pulls away
(PPP 382)
what is the second ‘A’ in APGAR?
Activity
muscle tone
(PPP 382)
how do we rate the second ‘A’ in APGAR?
0 = no activity/muscle tone
1 = some flexion, arms/legs flexed
2 = flexes arms and legs, resists extension, “active movement”
(PPP 382)
what is the R in APGAR?
Respiration
(PPP 382)
how do we rate the ‘R’ in APGAR?
0 = absent
1 = weak, irregular

what is Appearance 2 in APGAR rating?
pink baby (no cyanosis)
(PPP 382)
what is a normal score range for APGAR?
> = 7
(PPP 382)
what is a “fairly low” APGAR score range?
4-6 = fairly low
(PPP 382)
what is critically low for APGAR score?
<= 3
(SmartyPance)
what is fetal attitude?
Fetal attitude: relationship of fetal parts to one another
(SmartyPance)
what is ‘fetal lie’?
Fetal lie: relationship of fetal cephalocaudal axis (spinal column) to maternal cephalocaudal axis
(SmartyPance)
what is ‘fetal presentation’?
Fetal presentation: fetal/presenting part enters pelvic inlet first
(SmartyPance)
what are the two positions of fetal attitude?
fully flexed (normal) (chin on chest; rounded back with flexed arms, legs)
not flexed
(SmartyPance)
what are the three positions of ‘fetal lie’?
Longitudinal (ideal): fetal spine lies along maternal
Transverse: fetal spine perpendicular to maternal
Oblique: fetus at slight angle
(SmartyPance)
what are the three positions of ‘fetal presentation’?
cephalic (head first)
breach (bottom first)
breach (shoulder first)
(SmartyPance)
a breach presentation may be ______, ______, or _______.
A breech presentation may be frank, complete, or incomplete
(SmartyPance)
what is the treatment for breach presentation?
External cephalic version at or near term, followed by a trial of a vaginal delivery if the version is successful
and planned cesarean delivery if breech presentation persists
(SmartyPance)
how often do twins come along?
1 out of every 80 births
Twins occur in 1 out of every 80 births
(SmartyPance, PPP 363)
what are monozygotic twins?
Monozygotic (Identical) – multiple (typically two) fetuses produced by the splitting of a single zygote
formed from the fertilization of 1 ovum that splits (increased risk of fetal transfusion syndrome and discordant fetal growth
(SmartyPance PPP 363)
what are dizygotic twins?
Dizygotic (Fraternal) – multiple (typically two) fetuses produced by two zygotes
due to fertilization of 2 ova by 2 different sperm (66%)
(SmartyPance)
What kind of twins are fraternal twins?
Dizygotic (Fraternal) – multiple (typically two) fetuses produced by two zygotes
(SmartyPance)
what are polyzygotic twins?
Polyzygotic – multiple fetuses produced by two or more zygotes
(SmartyPance)
how are twins usually diagnosed?
DX: Often diagnosed at first screening ultrasound
(SmartyPance)
clues that there are twins growing?
Extra fetal heart tones
Elevated maternal alpha-fetoprotein (AFP)
Fundal height is usually greater than dates
(SmartyPance)
what do we do with the prenatal visits once we know there are twins?
Prenatal visits should occur more frequently to monitor and prevent maternal complications
(SmartyPance)
what is the most common complication for twins?
The most common complications are spontaneous abortion and preterm birth
(PPP 363)
how do we diagnose multiple gestations with lab?
elevated levels of beta-hCG
and
maternal serum alpha-fetoprotein higher than normal
