Guidelines regarding pregnancy for health


Slide Content

大连医科大学附属第二医院 妇产科
pregnance
guidance
Department of
Obstetrics&Gynecology
The 2nd affiliated hospital
of Dalian medical university

大连医科大学附属第二医院 妇产科
Aim:1.figure out the pregnance at risk
2.prevent the complication of pregnance
3.guarantee the safe of pregant women, fetus
and neonatus
perinatal period:28 weeks of completed
gestation to the first 7 days of life.
there are 4 international perinatal interval.
pregnance guidance
1.antenatal care
2.fetal assessment
3.placental and fetal maturity

大连医科大学附属第二医院 妇产科
1.Antenatal care
1.1 the time of antenatal care
once the early pregnancy has been diagnosed, the
history and physical examination must be taken.
the standard schedule:
0-32 weeks: once every 4 weeks
32-36weeks: once every 2 weeks
36 weeks to delivery: once each week

大连医科大学附属第二医院 妇产科
1.2 the content and methods
1.2.1 history
a.present history
EDC=LMP -3 months( & + 9 months ) + 7 days
b.previous pregnancy
c.medical history
d.surgical history
e.family history

大连医科大学附属第二医院 妇产科
a. general examination
development, nutrition, heigth(<145cm),
weight ( increased less than 500g per
week) , crater nipple, blood pressure,
edema and so on.
1.2.2 physical examination

大连医科大学附属第二医院 妇产科
b.obstetric examination
fetal examination
fetal size estimation
fetal presentation and position
leopold maneuvers
fetal heart rate interpretation(18-20weeks)
most clearly when near the back of fetus
pelvic examination
bony pelvis
pelvic soft tissue

大连医科大学附属第二医院 妇产科
leopold maneuvers

大连医科大学附属第二医院 妇产科
bony pelvis
*interspinal diameter, IS ( 23-26 cm)

大连医科大学附属第二医院 妇产科
*intercristal diameter, IC (25-28cm)

大连医科大学附属第二医院 妇产科
*external conjugate, EC
( 18-20 cm)
from the fifth lumbar vertebral
crest to the midpoint of upper
edge of pubic union

大连医科大学附属第二医院 妇产科
*intertuberal diameter, IT
& transverse outlet, TO
(8.5cm-9.5cm)
a fist can be used

大连医科大学附属第二医院 妇产科
*posterior sagittal diameter of outlet
from the midpoint of intertuberal diameter to
sacrum (8-9cm)
posterior sagittal diameter of outlet + intertuberal diameter > 15cm

大连医科大学附属第二医院 妇产科
*angle of pubic arch
(90°)

大连医科大学附属第二医院 妇产科
*internal pelvimetry
①diagonal conjugate, DC (12.5-13cm)
middle finger reaches the promontory of the sacrum
index finger is pushed against the pubic symphysis

大连医科大学附属第二医院 妇产科
②interspinous diameter (10cm)

大连医科大学附属第二医院 妇产科
pelvic soft tissue
consist of lower segment of uterus, cervix, vagina
and soft tissue of pelvic floor.

大连医科大学附属第二医院 妇产科
c. assisst examination
*lab. test
blood screening
routine blood test
blood type group
infective disease
OGTT
hCG & AFP
genetics testing
urine testing
proteinuria
urinary tract infection
*B-ultrasound

大连医科大学附属第二医院 妇产科
2.fetal assessment
2.1 fetal monitoring techniques
2.1.1 fetal movement
≥30 times/12h normal
<10times/12h hypoxia
2.1.2 fetal ECG and doppler velocimetry

大连医科大学附属第二医院 妇产科
2.1.3 B-ultrasound
*first trimester: gestational sac GS,
crown-rump length CRL
*second and third trimester:biparietal
diameter BPD, abdominal circumference
AC, femur length FL.

大连医科大学附属第二医院 妇产科
2.1.4 fetal heart rate interpretation

大连医科大学附属第二医院 妇产科

大连医科大学附属第二医院 妇产科
*fetal heart rate monitoring
baseline of fetal heart rate
normal:120-160bpm
tachycardia:>160bpm
bradycardia:<120bpm

大连医科大学附属第二医院 妇产科
variation of fetal heart rate
acceleration >15bpm, >15s

大连医科大学附属第二医院 妇产科
normal acceleration with tachycardia

大连医科大学附属第二医院 妇产科
deceleration
①early deceleration, ED

大连医科大学附属第二医院 妇产科
②variable deceleration, VD

大连医科大学附属第二医院 妇产科
③late deceletation, LD

大连医科大学附属第二医院 妇产科
*NST & OCT
NST:non stress test

大连医科大学附属第二医院 妇产科
OCT, oxytocin challenge test
(contraction stress test ,CST)
intravenous infusion of dilute oxytocin until 3
contractions occur in 10 minutes
negative: no deceleration
positive:late deceleration

大连医科大学附属第二医院 妇产科
2.1.5 manning scoring method
2' 0'
NST ≥ 2 times of FM, less than 2 times
acceleration≥15bpm,≥15s ≤15bpm,≤15s
FBM ≥ 1 times, non or ≤ 30s
lasting ≥ 30s
FM ≥ 3 times of movement ≤ 2 times
FT ≥ 1 tension no tension
AFV MVP(maximum vertical pocket)
≥2cm <2cm

大连医科大学附属第二医院 妇产科
2.1.6 amnioscopy
2.1.7 placental function
*estriol
*HPL(Human Placental Lactogen)
*pregnancy-specific glycoprotein
*fetal movement
*OCT
*vaginal smears
*manning scoring & B-ultrasound & fetal heart rate
*interpretation

大连医科大学附属第二医院 妇产科
2.2 fetal maturity
fat cell appearance 20% maturity of skin
lecithin/
sphingomyelin >2 maturity of lung
creatinine ≥176.8umol/L maturity of kidney
bilirubin OD450<0.02 maturity of kidney
amylase ≥450U/L maturity of salivary gland
test value significanced
