Study Notes

Pediatric Vital Signs Changes

Heart Rate (HR) and Respiratory Rate (RR) decrease with age; Blood Pressure (BP) increases.
Newborn to 6 months BP norm: 65-90 / 45-65 mmHg
6 months to 3 years BP norm: 80-105 / 55-70 mmHg
4 to 12 years BP norm: 95-120 / 60-75 mmHg
Over 12 years BP norm: 110-120 / 65-85 mmHg

Methods for Assessing Pediatric Vital Signs

Temperature: Use axillary or oral methods; normal range is 97.9-99°F (36.6-37.2°C).
Heart Rate: Measure apical pulse for a full minute in neonates and children with cardiac issues.
Use 4th intercostal space for children up to 7 years; 5th intercostal for those over 7 years.
Respirations: Observe full breathing cycle for a minute. Up to 7 years: diaphragmatic breathers; over 7 years: thoracic breathers.
Blood Pressure: Measured on the right arm; cuff size should be 40% of arm circumference. Infants measured on the leg.

Tanner Stages of Development

Stage 1: No sexual hair in both genders.
Stage 2: Downy hair for males; breast budding for females.
Stage 3: Scant terminal hair; further breast enlargement in females.
Stage 4: Full terminal hair in males; papillae form secondary mound in females.
Stage 5: Adult-type terminal hair in males and mature breasts in females.

Cyanosis in Newborns

Normal Finding: Acrocyanosis (cyanosis in extremities and lips), resolves with warming.
Abnormal Finding: Central cyanosis (cyanosis in mouth, head, torso), indicative of low oxygen levels.

Fontanelles Closure

Anterior fontanelle closes around 18 months.
Posterior fontanelle closes between 2-3 months (6-8 weeks).

Ear Examination

Pediatric ear assessment requires pulling down and back for proper view.

Breathing Patterns in Children

Abdominal breathers until about 6-7 years; nose-breathing obligate for infants.

Palpation of PMI (Point of Maximal Impulse)

Under 4 years: palpate at the 4th intercostal space.
Over 4 years: palpate at the 5th intercostal space.

Hip Dysplasia Assessments

Ortolani Test: Reduces a dislocated hip; positive if femoral head slips into the socket with a palpable clunk.
Barlow’s Test: Attempts to dislocate the hip; positive if the hip slides out of the acetabulum.
Galeazzi Sign: Assesses leg length and knee position; unequal skin folds indicate potential hip dislocation.

Scoliosis Evaluation

Adams Bend Forward Test: Lateral curvature of the spine; degree ≥ 7 requires further evaluation.

Normal vs Abnormal Thorax in Infants

Infant thorax: anterior/posterior diameter equal to transverse until 1 year; chest circumference matches head circumference.
Signs of respiratory distress include tachypnea and nasal flaring.

Infant Reflexes

Babinski Reflex: Dorsiflexion of the great toe, fanning of other toes; disappears by 12-18 months.
Moro Reflex: Disappears by 4 months.

Newborn Abdomen Assessment

Normal abdomen shape: rounded and protuberant; potbellied appearance in children up to 4 years.
Abnormal shapes include:
- Distended: potential intestinal obstruction or organomegaly.
- Scaphoid: may indicate malnutrition.
Normal umbilical hernia resolves by 3 weeks; diastasis recti heals on its own.

Abnormal Findings in Newborn Abdomen

Pyloric Stenosis: Thickening of pylorus leading to vomiting; palpable mass may be found.
Intussusception: Part of the intestine slips into another; characterized by a sausage-shaped mass, vomiting, and current jelly stools; considered an emergency.

Pediatric Heart Rate Ranges

Infants: Normal heart rate is 120-160 beats per minute (bpm).
Adolescents: Normal heart rate is 60-100 bpm.
Heart rate decreases with age due to cardiovascular system maturation.

Anterior Fontanel Closure

The anterior fontanel typically closes between 18-24 months.
This closure allows for rapid brain growth in infancy.

Measuring Respiratory Rate

Measure respiratory rate by observing the chest rise and fall for one full minute while the child is at rest.
A full minute ensures accurate measurement due to irregular breathing patterns in children.

Tanner Stages

Tanner stages are used to assess physical development based on external sexual characteristics.
Staging ranges from 1 (prepubertal) to 5 (full maturity), helping track puberty progression.

Ortolani Test

A positive Ortolani test is indicated by a "clunk" sound during hip abduction, suggesting a dislocated hip that reduces into the acetabulum.
Used to screen for developmental dysplasia of the hip in newborns.

Identifying Central Cyanosis

Central cyanosis in newborns is identified by bluish discoloration of lips, tongue, and central body areas.
Indicates a lack of oxygen in the bloodstream and represents a medical emergency.

Breathing Transition in Children

Children typically switch from abdominal to thoracic breathing around 7 years old.
Younger children predominantly use abdominal muscles for breathing.

Palpable Thrills in Heart Murmurs

A palpable thrill suggests a heart murmur of grade 4/6 or higher, indicating significant heart defects.
Thrills are felt vibrations on the chest wall associated with turbulent blood flow.

Point of Maximal Impulse (PMI)

In children under 4 years old, the PMI is located in the 4th intercostal space, midclavicular line.
The heart’s position differs in younger children due to smaller chest sizes.

Adam's Forward Bend Test

A positive Adam's forward bend test shows ribcage height asymmetry, indicating scoliosis.
Used for visual assessment of spinal curvature.

Babinski Reflex

The Babinski reflex causes the toes to fan out when the sole of the foot is stroked.
This reflex is normal in infants but typically disappears by age 1.

Intussusception vs. Pyloric Stenosis

Intussusception: Sudden severe abdominal pain and "currant jelly" stools.
Pyloric stenosis: Projectile vomiting and an olive-shaped abdominal mass.
Both conditions are common in infants with distinct clinical presentations.

Infant Thorax Characteristics

An infant's thorax is barrel-shaped with horizontal ribs.
This shape supports rapid growth and meets breathing needs.

Ear Examination in Children

Position the ear by pulling the auricle down and back during an examination.
This straightens the ear canal, aiding visualization in children under 3 years old.

Acrocyanosis in Newborns

Acrocyanosis presents as bluish discoloration of hands and feet.
It is a normal and benign condition in newborns caused by immature circulatory regulation.

Newborn Blood Pressure

Normal blood pressure range for newborns is 65-85/45-55 mmHg.
Newborns typically have lower blood pressure than older children and adults.

Pediatric Intramuscular Injection Site

The recommended site for intramuscular injections in children under 2 years is the vastus lateralis muscle in the thigh.
This site has adequate muscle mass with a lower risk of nerve or blood vessel injury.

Annual Influenza Vaccination

Children should start receiving annual influenza vaccinations at 6 months old.
Early vaccination helps protect against influenza and its complications.

Barlow Test

The Barlow test assesses hip instability or dislocation in infants.
A positive test is indicated by feeling the hip dislocate from the acetabulum with gentle posterior pressure.

Posterior Fontanel Closure

The posterior fontanel should close by 2-3 months of age.
It is smaller compared to the anterior fontanel and closes earlier.
