    Study Notes

    Signs of Pregnancy

    • Chadwick's Sign: Bluish discoloration of the vagina and cervix.
    • Goodell's Sign: Softening and cyanosis of the cervix occurs at or after 4 weeks gestation.
    • Ladin's Sign: Softening of the uterus noted after 6 weeks of pregnancy.

    Hemodynamics and Cardiac Changes

    • Cardiac output (CO) increases by 30-50% during pregnancy.
    • Systemic vascular resistance (SVR) and arterial blood pressure (BP) decrease, mainly due to elevated progesterone levels; systolic BP drops by 5-10 mmHg and diastolic BP by 10-15 mmHg, peaking at week 24.

    Respiratory Changes

    • Tidal volume increases by 30-40% during pregnancy.
    • Total lung capacity decreases by 5% due to diaphragm elevation.

    Nausea and Hormonal Changes

    • Nausea in pregnant individuals is attributed to increased levels of estrogen, progesterone, and hCG, typically resolving by 14-16 weeks.

    Renal Function

    • Glomerular filtration rate (GFR) increases by 50% in early pregnancy, influenced by RAAS activation increasing aldosterone levels.
    • Red blood cell (RBC) volume also rises by 20-30%.

    hCG Levels

    • Human chorionic gonadotropin (hCG) doubles every 48 hours during early pregnancy, peaking between 10-12 weeks, then declining and stabilizing after week 15.
    • The placenta produces hCG, which helps maintain the corpus luteum during early pregnancy.

    Nutritional Requirements

    • Caloric needs increase to 300 calories/day during pregnancy and 500 during breastfeeding, with heightened requirements for protein, iron, folate, and calcium.

    Prenatal Care Guidelines

    • Pregnancy tests should be conducted 14 days after the last sexual intercourse in women with irregular cycles or unknown last menstrual periods.
    • Serum tests are the most sensitive for pregnancy detection.
    • Naegle's rule is utilized to estimate due dates: LMP - 3 months + 7 days.

    Components of Pregnancy Visits

    • Initial prenatal visits occur between 6-10 weeks, with regular follow-ups scheduled every 4 weeks until 32 weeks, biweekly until 36 weeks, and weekly thereafter.
    • A comprehensive history taken includes current pregnancy symptoms and previous obstetric history.

    Monitoring Fetal Development

    • Fundal height is assessed starting at 20 weeks; it corresponds roughly to gestational age.
    • Fetal cardiac activity can be detected as early as week 6, and by week 5, the fetal yolk sac should be visible.

    Screening and Tests

    • Initial visit tests include complete blood count, blood type, rubella immunity, sexually transmitted infections, urine analysis, HIV screening, and early aneuploidy screening.
    • Second-trimester testing typically includes MSAFP/triple or quad screen and obstetric ultrasound.
    • Third trimester tests are often hematocrit, glucose tolerance tests, and group B strep cultures.

    Complications in Multiple Gestation

    • Increased risks include spontaneous abortion, preterm birth, and fetal complications such as growth restriction or congenital anomalies.
    • Types of twins include monozygotic (identical) and dizygotic (fraternal), with specific monitoring required for conditions like twin-twin transfusion syndrome.

    Abortion and Ectopic Pregnancy

    • Spontaneous abortion is defined as pregnancy termination before 20 weeks, with risks including smoking, infection, and systemic diseases.
    • Ectopic pregnancies occur outside the uterus, primarily in the Fallopian tubes, often due to tube occlusion.

    Placenta Previa and Abruptio Placentae

    • Placenta previa involves abnormal placenta position, causing bleeding and risks for the fetus, often diagnosed via ultrasound.
    • Abruptio placentae is the premature separation of the placenta from the uterine wall after 20 weeks, presenting as severe abdominal pain and bleeding.

    Management and Complications

    • Treatment for complications like ectopic pregnancy may include methotrexate and careful monitoring; surgical intervention may be necessary.
    • Routine monitoring for gestational trophoblastic disease includes hCG levels, with complete and partial moles exhibiting different symptoms.

    Key Takeaway Points

    • Pregnancy entails significant physiological changes across multiple systems, emphasizing the need for careful monitoring and management.
    • Understanding signs, symptoms, complications, and appropriate interventions is critical for ensuring maternal and fetal health.
