𝖣 Ultrasound
What are the kinds of diagnostic test? 𝖣 Chorionic Villus Sampling (CVS)
𝖣 Amniocentesis
High-frequency sound waves are aimed at body tissues
✣ directed through tissues of the abdomen or vagina to provide two-dimensional
Ultrasound
images
𝖣 Quick and easy
Images have greater detail
Three dimensional ultrasound ✣ they provide more detailed, accurate identification of the extent and size of
abnormalities
𝖣 Shows movement as it happens
𝖣 Allows the observer to see fetal heart motion, fetal breathing activity, and fetal
Real-time scanning ultrasound
body movement
𝖣 Can distinguish between moving tissues of the fetus and maternal tissues
• Some parents are excited.
• Some parents report anxiety.
Ultrasound: Emotional Response • Many couples expect to know the gender of the fetus.
• Others do not want to know the gender.
• Sonographers often give parents a still image.

1. Naegele's rule
3 different ways to determine
2.Fundal measurement
gestational age
3. Ultrasound
At 20 weeks where should the fundus be? At the umbilicus
How will a sonographer measure From crown to rump
gestational age using an ultrasound?
Standard (basic)
✣ General survey
𝖣 Example: anatomy scan
Specialized (comprehensive)
Levels of obstetrics via Ultrasound ✣ Specific
𝖣 Example: looking for abnormalities
Limited
✣ Address a specific question
𝖣 Example: fetal presentation
Which type of ultrasound would be used Specialized ultrasound
to look for a specific congenital
defect?
A nurse goes to check the presenting part Limited
and touches something squishy but is -help determine fetal presentation
unsure what she's feeling. What type of
ultrasound would the doctor order to
help determine what it is?
Purpose
• Confirm pregnancy
• Verify the location of the pregnancy
• Detect multifetal gestations
• Determine gestational age
Ultrasound: First Trimester • Identify markers
• Determine the locations of the uterus, cervix, and placenta for procedures
such as chorionic villus sampling (CVS) (if needed)
Procedure
• done transvaginal
Purpose
• Confirm viability
• Evaluate fetal anatomy
• Determine gestational age
• Assess serial fetal growth
• Compare growth of fetuses in multifetal gestations
Ultrasound: Second and Third Trimester • Evaluate four of five markers in a biophysical profile (usually during 3rd trimester)
• Locate the placenta when placenta previa is suspected
• Determine fetal presentation
• Guide needle for amniocentesis or percutaneous umbilical cord sampling (PUBS)
Procedure
• Transabdominal
