    Study Notes

    Pediatric Care and Developmental Stages

    • Pediatrics focuses on the medical care of infants, children, and adolescents, recommended up to age 21 by the American Academy of Pediatrics.
    • Key age groups include:
      • Perinatal period: From 20th week of gestation to six days post-birth.
      • Neonatal period: First 28 days after birth.
      • School age: From 6 years to adolescence.

    Growth Patterns

    • Rapid growth occurs in infancy and early childhood, with a switch to slow and steady growth in middle childhood (ages 8-10).
    • Puberty initiates rapid growth; secondary sexual characteristics begin to emerge.
    • Growth slows in late adolescence until adult height is achieved.

    Anatomical and Physiological Changes

    • Typical 2-3-year-olds exhibit mild lumbar lordosis and a protuberant abdomen.
    • As abdominal strength increases, pelvic alignment matures, decreasing lordosis by early school age.
    • Growth rate is a critical health indicator, with anthropometric measurements essential for monitoring health status.

    Factors Influencing Growth

    • Growth is influenced by hereditary and environmental factors, including prenatal conditions and nutritional status.
    • Socio-economic status, nutrition, and emotional factors can significantly impact growth and development.
    • Neurologic impairments and systemic diseases may cause growth retardation.

    Neurologic Conditions Impacting Growth

    • Conditions like brachial plexus palsy and myelodysplasia can result from maternal diabetes and folic acid deficiency.
    • Microcephaly can arise from maternal infections, like Zika virus, and hydrocephalus involves fluid obstruction in the brain.

    Key Vital Statistics

    • Normal heart rate ranges from 100 to 160 beats per minute (apical).
    • Respiratory rates for newborns vary from 30 to 60 breaths per minute, averaging 40.
    • Average blood pressure at birth is approximately 75/42 mmHg.

    APGAR Score Evaluation

    • APGAR assesses:
      • Heart Rate: Normal = Over 100
      • Respiratory Efforts: Normal = Good cry
      • Muscle Tone: Normal = Active motion
      • Reflex Response: Normal = Grimace and cry
      • Color: Normal = All body pink
    • Scores ranging from 7-10 indicate normal condition.

    Fontanelles

    • Anterior fontanelle: Diamond-shaped, located at the junction of frontal and parietal bones; closes at 12-18 months.
    • Posterior fontanelle: Triangular; located between occipital and parietal bones; closes within the first month.

    Growth Measurements

    • Height measurements at significant ages:
      • Birth: 50 cm
      • 12 months: 75 cm
      • 4 years: 100 cm
    • Weight guide:
      • Birth weight (full term): 3.4 kg.
      • Weight doubles by 5 months and triples by 12 months; expect 2 kg annual increases until adolescence.

    Developmental Screening

    • Evaluation milestones:
      • Lack of head control at 4-6 months may suggest hypotonia.
      • Absent smile or babbling by corresponding months should trigger further investigation for developmental delays.
      • Primitive reflexes persisting beyond 6 months can indicate neuromuscular disorders.
