Study Notes
Learning Objectives
- Define menstrual/gestational age, fertilization/ovulatory age, antepartum period, and normal pregnancy.
- Explain physiological and psychological changes during normal pregnancy.
Normal Pregnancy
- Characterized by typical physiological changes without significant complications.
- Full-term duration ranges from 37 to 42 weeks, averaging 40 weeks.
- Associated with normal fetal growth and maternal health.
Gestational Age
- Calculated from the first day of the last menstrual period (LMP).
- Example: 8 weeks pregnant means 8 weeks since LMP.
Antepartum Period
- The duration of pregnancy from conception until the onset of labor.
Trimesters of Pregnancy
- Divided into three trimesters:
- First Trimester: Up to 12 weeks
- Second Trimester: 13 to 28 weeks
- Third Trimester: 29 to 40 weeks
Physiological Changes During Pregnancy
- Involves progressive anatomical and physiological adaptations to support fetal growth.
- Changes influenced by hormones and external factors.
Reproductive System
- External Genitalia: Edema and increased vascularity; pigmentation and varicosities in labia minora.
- Internal Genitalia:
- Uterus increases from 60g to 900g; hypertrophy and hyperplasia under estrogen and progesterone.
- Increased uterine blood supply and changes in position leading to urinary frequency.
- Changes in isthmus and cervix include increased vascularity and softening.
Circulatory System
- Blood volume increases by 30%; cardiac output rises to 5-7 liters/min.
- Plasma volume increases by 50% leading to physiological anemia.
- Hypercoagulability state increases risk for thrombosis.
- Blood pressure variations occur throughout pregnancy, particularly lowering mid-pregnancy.
Respiratory System
- Oxygen requirements increase by 20%.
- Relaxation of pulmonary muscles; possible shortness of breath in late stages.
Gastro-Intestinal System
- Common issues include gingival hypertrophy, heartburn, and constipation due to hormone-induced muscle relaxation.
- Changes in taste and cravings, including pica.
Urinary System
- Increased glomerular filtration rate (GFR) and renal pelvis dilation.
- Frequency increases, especially in early and late pregnancy, due to uterine pressure.
Integumentary System
- Increased sweating and altered pigmentation, leading to conditions like chloasma and striae gravidarum.
Endocrine System
- Enlargement of thyroid glands; insulin resistance increases due to human placental lactogen.
Musculo-Skeletal System
- Ligaments relax, accommodating growth in pelvic capacity.
Nervous System
- Risk of carpal tunnel syndrome due to median nerve compression.
- Mood swings and potential psychosis, especially with family history.
Metabolic Changes
- Basal metabolic rate (BMR) increases by 30% in later pregnancy.
- Daily energy requirements increase by 300k calories.
Weight Gain and Water Metabolism
- Average total weight gain is about 12 kg, with specific distribution over the trimesters.
Psychological Changes in Pregnancy
- Influenced by factors like general health, age, emotional maturity, and socioeconomic status.
- First Trimester: Shock and ambivalence.
- Second Trimester: Calmness and anticipation as fetal movement is felt.
- Third Trimester: Increased anxiety and readiness for childbirth.
