Study Notes
Electronic Fetal Monitoring (EFM)
- EFM is a method used to monitor fetal heart rate (FHR) and uterine contractions during pregnancy and labor.
- External monitoring uses a device placed on the mother's abdomen.
- Internal monitoring requires insertion of a device into the uterus, which allows for more accurate measurements.
Indications for EFM
Maternal Indications
- High blood pressure (hypertension)
- Diabetes
- Labor induction or augmentation
- Previous cesarean birth
- Prolonged rupture of membranes
- Antepartum hemorrhage
- Post-term pregnancy (over 42 weeks)
- Premature labor
Fetal Indications
- Fetal growth restriction
- Prematurity (under 37 weeks)
- Abnormal fetal heart rate
- Low amniotic fluid (oligohydramnios)
- Congenital malformations
- Multiple pregnancies
- Breech presentation
Methods of Fetal Heart Rate and Uterine Contraction Monitoring
Indirect (External Monitoring)
- Uses external transducers placed on the mother's abdomen.
- One transducer measures FHR using ultrasound.
- The other transducer measures uterine contractions using a toco transducer.
Advantages
- Easy to apply
- Non-invasive
- Safe for mother and fetus
Disadvantages
- Difficult to use with obese women
- Restricts maternal mobility
- Difficult to accurately assess contraction intensity
Direct (Internal Monitoring)
- Uses internal devices placed within the uterus.
- An Intrauterine Pressure Catheter (IUPC) monitors uterine contractions.
- A Fetal Scalp Electrode (FSE) monitors fetal heart rate.
Advantages
- Most accurate method for assessment
Disadvantages
- Requires cervical dilation
- Requires skilled practitioner to apply
- Can be uncomfortable for the mother
- Requires sterile equipment
- May be impossible to insert if the fetus is at a low station
- Difficult to attach FSE in the presence of thick fetal hair
Interpretation
1- Uterine Activity
- Frequency: The amount of time between the start of one contraction to the start of the next contraction.
- Duration: The length of time from the start of a contraction to the end of the same contraction.
- Resting Tone: How relaxed the uterus is between contractions.
- Interval: The period of time between the end of one contraction to the beginning of the next contraction.
- Normal: Less than or equal to 5 contractions in 10 minutes.
- Abnormal: More than 5 contractions in 10 minutes.
Fetal Heart Rate Parameters
- Baseline Fetal Heart Rate: The average FHR between contractions.
- Accelerations: Transient increases in FHR above baseline, usually associated with fetal movement.
- Decelerations: Transient decreases in FHR below baseline, which can be classified into early, late, or variable types.
Partograph
- A graphical tool used to monitor the progress of labor.
- Tracks various parameters over time, including cervical dilation, fetal heart rate, uterine contractions, and maternal vital signs.
- Helps identify potential complications and guide clinical decisions.
