Ch 26 High Risk Pregnancy Flashcards
Nonstress Test (NST)
reactive :) = want an acceleration of at least 20 bpm for at least 20
can start at 32 weeks
seconds two times during 20 minutes
acceleration- bpm increase
want a baseline of 120-160bpm
typically done 2x/week
VEAL CHOP
Variable Deceleration
deceleration present without contraction
(result of cord compression)
have mom repo
Early Deceleration
before contraction there is a deceleration starting (a result of head compression)
base of deceleration mirrors peak of contraction
mom is probs in labor
Acceleration
this is OK :)
Late Deceleration
deceleration after a contraction
(result of placental insufficiency)
NOT good
FSE
fetal scalp electrode
monitor screwed into fetal scalp to measure heart rate
TOCO
IUPC
intrauterine pressure catheter
inserted through cervix and into uterus
measures actual contraction and intensity
vibroacoustic stimulation
stimulates baby
done if no fetal movemengts
contraction stress test
stimulate contractions in mom (nipple stimulation or pitocin) and watch fetal heart rate response to contractions
Biophysical Profile (BPP)
use NST and US to assess baby’s wellbeing
each (8 or 10 total points)
fetal breathing movements (1 breathing episode= 2pts)
gross body movements (3+ trunk or limb movements= 2pts)
fetal tone (at least 1 neck and head extension= 2 pts)
amniotic fluid intake (5cm+= 2pts)
fetal heart rate (NST reactive= 2 pts, nonreactive=0 pts)
Daily Fetal Movement (DFMC)
32-34 weeks
want 5+ movements per hour
if less than 3= NST
Gravida Para
G total # of pregnancies
T 37+ wks
P 20-37 wks
A abortions/miscarriages AND less than 20 wk stillbirths
L living children
chorionic villus sampling
cannot do at 13 weeks or earlier, will cause limb deformities
ultrasonography
not diagnostic
abdominal=full bladder, more useful in 2nd and 3rd trimesters
transvaginal=empty bladder
can provide gestational age, fetal anatomy and growth
