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.
