High Risk Pregnancy: Assessment & Screening Flashcards
Percentage of pregnancies that are high risk
29-30%
A pregnancy complicated by a disease or disorder that may endanger life or affect the health of the mother, fetus, or newborn
HIGH-RISK PREGNANCY
Examples of High Risk Pregnancy
- Bad obstetrics history
- Heart disease
- Diabetes
- Twins/triplets
- Hypertension / preeclampsia
- Severe anemia
- Placental Abortion
- Threatened preterm labor
- Hemolytic anemia
- Thrombocytopenia
- Bleeding disorders
- Thalassemia
- History of thrombosis
Any ascertainable characteristic or circumstance of a person (or group) known to be associated with abnormal risk of developing or being adversely affected by a morbid process
RISK FACTOR
Example of High Risk Labor
- Preterm
- Previous caesarian section
- Cephalopelvic disproportion
- Prolonged labor
- Obstructed labor
- Shoulder dystocia
- Retained placenta
- Inversion of uterus
- Ruptured uterus
- Perineal tear
Process for defining the nature of that problem, determining a diagnosis, and developing specific treatment recommendations
ASSESSMENT
Process of identifying apparently healthy people who may be at increased risk of a disease or condition
SCREENING
Screening of high risk cases is preferably done on what trimester?
FIRST TRIMESTER
It is a test to establish the presence (or absence) of disease as basis for treatment in decisions in symptomatic or screen positive individuals
DIAGNOSTIC TEST
Examples of Diagnostic Tests for High Risk Pregnancy
- Fetal ultrasound / ultrasonic testing
- Cardiotography (CTG)
- Non-stress test (NST)
- Contraction Stress Test (CST)
- Chorionic villus sampling
- Amniocentesis
- Embryoscopy
- Fetoscopy
- Percutaneous umbilical cord blood sampling
A test done during pregnancy that uses reflected sound waves to produce a picture of a fetus, the placenta, and amniotic fluid
FETAL ULTRASOUND
The pictures of a fetal ultrasound are called ______
SONOGRAM
This ultrasound is done on _____ trimester to:
- Determine how pregnancy is progressing
- Find out if female is pregnant with more than 1 fetus
- Estimate the age of the fetus (gestational age)
- Estimate the risk chromosome defect (DS)
- Check for birth defects that affect the brain / spinal cord
1ST TRIMESTER
Non-Invasive Diagnostic tests
- Fetal ultrasound
- Cardiotography
- Non-Stress Test
- Contractility Test
This ultrasound is done on _____ trimester to:
- Estimate gestational age of fetus
- Look at size & position of fetus, placenta, and amniotic fluid
- Determine position of fetus, umbilical cord
- Detect major birth defects
2ND TRIMESTER
This ultrasound is done on _____ trimester to:
- Make sure that a fetus is alive & moving
- Look at size and position of fetus, placenta, amniotic fluid
3RD TRIMESTER
Machine used to perform monitoring in Cardiotography
CARDIOTOGOGRAPH (electronic fetal monitor)
A technical means of recording the fetal heartbeat and the uterine contractions during pregnancy (usually 3rd trimester)
CARDIOTOGRAPHY
At what week is chorionic villus sampling done?
10-12 weeks gestation
These structures contain cells from the developing fetus. A test that removes a sample of these cells thru a needle is called ______
CVS - CHORIONIC VILLUS SAMPLING
Also known as fetal heart rate monitoring in which a baby’s heart rate is monitored to see how it responds to the baby’s movement
NON-STRESS TEST
A test performed near the end of pregnancy to determine how well the fetus will cope w/ contractions of childbirth. The aim is to induce contractions and monitor the fetus to check for heart rate abnormalities using cardiotocograph
CONTRACTION STRESS TEST (CST)
These are small structures in the placenta that act like blood vessels
CHORIONIC VILLI
A form of prenatal diagnosis to determine chromosomal or genetic disorders in the fetus
CHORIONIC VILLUS SAMPLING (CVS)
