Intrapartum Fetal Surveillance: Flashcards
What is a fetoscope used for?
auscultation and palpation
- midwife uses in community
What is a a Doppler ultrasound used for?
auscultate fetal heartbeat
Benefits of auscultation and palpation
- Easy, inexpensive and less invasive
- Results comparable to EFM in low risk women
- Comfortable and allows freedom of movement
- Can be used with hydrotherapy (water birth)
Limitations of auscultation and palpation
- Inability to perform in some situations
- No permanent record
- FHR counting is intermittent not continuous
- May not detect abnormal FHR at all, or in time for intervention- bc it’s intermittent
- Not recommended for high risk pregnancy
What are the two monitors of a bedside electronic fetal monitor (EFM)?
Where do you place them for use?
- tocometer: measures uterine contractions
— Placed at the fundus, top of uterus - Ultrasound: placed on back of fetus, must know fetal positions
- External monitor cannot determine the intensity of contraction

Benefits of Doppler and EFM:
- Noninvasive
- Ease-of-use
- No risk to mother or fetus
- Provides continuous FHR and UA readings
Limitation of Doppler and EFM
- Limits mobility of mother
- Does not assess strength or intensity of contractions
- Limited effectiveness in obese or multifetal women
What needs to happen before using an:
Intrauterine pressure catheter (IUPC)
- Mom needs to be dilated at least 2 cm
- and her membranes need to be ruptured
FHR MONITOR STRIP:
Each box = how many secs?
10 secs
6 boxes = 1 min
Assending boxes= FHR
