- Blood test (bhCG)
- Ultrasound (dating scan)
Describe the public model of routine antenatal care.
- Midwifery led care
- Obstetrician overseen
- Birth centre
Describe the private model of routine antenatal care.

List the most common scans and tests associated with antenatal care.
- Dating scan (confirmation of pregnancy 4-11 weeks)
- Nuchal translucency (12-14 weeks) and bloods
- Morphology scan (18-20 weeks)
- Developmental anomalies and placental position
- 28 weeks GTT (2hr blood test series)
- 34 weeks rescan for placenta (if high risk)
- 36 weeks growth scan (if high risk)
Name four tests for foetal chromosomal anomalies during pregnancy.
- Nuchal translucency scan and pathology
- NIPT (non-invasive pregnancy testing) - blood test that gives sex
- Chorionic Villus sampling - samples placenta and gives full genetic breakdown
- Amniocentesis
What chromosomal abnormalities can nuchal translucency detect?
- Trisomy 13 (Patau syndrome, incompatible with life)
- Trisomy 18 (Edwards syndrome, incompatible with life)
- Trisomy 21 (Downs syndrome)
Chorionic Villus sampling has an increased risk of what, and why is the risk generally accepted?
MC; sometimes still accepted as termination can still be performed if chromosomal abnormalities incompatible with life are detected.
Amniocentesis has an increased risk of what?
MC
What is the definition of spontaneous abortion?
The complete loss of the products of conception prior to the 24th week of pregnancy.
____% to ____% of diagnosed pregnancies are lost before 20 weeks.
10-15%
Most pregnancies lost before 20 weeks are lost before what physiological event?
Implantation.
How many pregnancies lost before 20 weeks are clinically recognised as an MC?
~a quarter.
True or false: the incidence of loss is higher in IVF and AMA pregnancies.

What is the definition of early MC?
MC occurring prior to 12-13 weeks gestation.
____% of MC are early MC (before 12-13 weeks gestation).
80%
What is the presentation of early MC?
- Painful or painless PV bleeding (usually not significant volume but can alarm mothers)
- Often associated with lower central abdominal cramping
- Often anxiety and distress
Describe the mx of early MC.
- Rest and reassurance
- Analgesia (morphine - won’t hurt infant at this point)
- Monitor VSS and PV loss
- Ascertain intrauterine scans if available
- Tx to hosp
What is the definition of late MC?
MC which happens from 13-24 weeks gestation.
What is the presentation and mx of late MC?
- Often painful lower abdo cramps or contraction pains
- Often PV fluid or blood loss
- Birth en-caul is common (remove this)
- Birth foetus
- Will be small yet well formed
- May show signs of life
- Breathing, movement, heart beat
- Same basic post-natal cares as for term birth
- Very emotive
- Rx like a baby
- ROLE not required
What are the limits of viability?
- The gestation at which resuscitation is not commenced following preterm birth
- 22 weeks in hospital is viable for resuscitation
- Is mostly futile
- Significant sequelae
- Can be commenced at maternal request from 20K
What is an ectopic pregnancy?
When a fertilised ovum implants itself outside the uterine cavity.
What is the most common site of implantation of an ectopic pregnancy?
Fallopian tube (95% of cases)
Ectopic pregnancy is commonly dx between ____ and ____ weeks gestation.
6 and 10
