Study Notes
Maternal Newborn Assessment
Fetal Heart Monitoring
- Purpose: To assess fetal well-being and detect any potential complications during pregnancy and labor.
-
Methods:
- External Fetal Monitoring: Utilizes ultrasound transducers placed on the mother’s abdomen to measure fetal heart rate (FHR).
- Internal Fetal Monitoring: Involves placing a small electrode on the fetal scalp to provide more accurate FHR readings.
- Normal Fetal Heart Rate: 110-160 beats per minute.
-
Variability: Indicates fetal well-being; categorized as:
- Absent: 0 bpm variability.
- Minimal: <5 bpm variability.
- Moderate: 6-25 bpm variability (normal).
- Marked: >25 bpm variability.
- Accelerations: Temporary increases in FHR, typically a sign of fetal well-being.
-
Decelerations: Temporary decreases in FHR categorized as:
- Early: Associated with contractions; indicates head compression.
- Variable: Abrupt decreases; may indicate cord compression.
- Late: Occurs after contraction; suggests uteroplacental insufficiency.
- Continuous vs. Intermittent Monitoring: Continuous provides ongoing assessment, while intermittent checks are done at intervals.
Maternal Health History
- Importance: Establishes a baseline for maternal health and identifies risk factors for complications.
-
Components to Assess:
- Medical History: Previous surgeries, chronic illnesses (e.g., diabetes, hypertension).
- Obstetric History: Number of pregnancies, outcomes (live births, miscarriages), gestational age at delivery, any complications in previous pregnancies.
- Family History: Genetic disorders, pregnancy-related complications (e.g., preeclampsia).
- Social History: Substance use (tobacco, alcohol, drugs), support systems, socioeconomic factors.
- Current Medications: Prescription drugs, over-the-counter medications, herbal supplements.
- Gynecological History: Menstrual cycle regularity, history of STIs, contraceptive use.
- Risk Assessment: Identifying high-risk conditions that might require closer monitoring or intervention during pregnancy and childbirth.
Fetal Heart Monitoring
- Objective: Assess fetal well-being, identify potential complications during pregnancy and labor.
- External Fetal Monitoring: Employs ultrasound transducers on the mother's abdomen to track fetal heart rate (FHR).
- Internal Fetal Monitoring: Involves an electrode on the fetal scalp for precise FHR measurements.
- Normal FHR Range: Typically between 110-160 beats per minute.
-
Variability: Reflects fetal health; assessed as:
- Absent Variability: No fluctuations (0 bpm).
- Minimal Variability: Small fluctuations (up to 25 bpm).
- Accelerations: Temporary FHR spikes, generally indicating a healthy fetal condition.
-
Decelerations: Temporary drops in FHR classified into:
- Early Decelerations: Happen with contractions, suggest head compression.
- Variable Decelerations: Sudden drops, potentially signal cord compression.
- Late Decelerations: Occur after contractions, indicating possible uteroplacental insufficiency.
- Monitoring Approach: Continuous monitoring offers real-time assessment; intermittent monitoring occurs at set intervals.
Maternal Health History
- Significance: Establishes maternal health baseline and identifies risks for complications.
- Medical History Review: Includes past surgeries and chronic conditions like diabetes and hypertension.
- Obstetric History Evaluation: Focus on the number of pregnancies, outcomes (live births/miscarriages), gestational ages, and previous complications.
- Family History Inquiry: Assess for genetic disorders and any pregnancy-related complications (e.g., preeclampsia).
- Social History Consideration: Looks into substance use (tobacco, alcohol, drugs), social support, and economic status.
- Current Medications Review: Lists all medications, including prescriptions, over-the-counter drugs, and herbal supplements.
- Gynecological History Assessment: Evaluates menstrual cycle regularity, STI history, and contraceptive usage.
- Risk Assessment: Identifies conditions needing closer monitoring or interventions during pregnancy and childbirth.
