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.
