Why Pediatric Nursing is Unique

• Children are continuously growing and developing.
• Normal findings in children change significantly with age.
• Children have limited physiologic reserves and can compensate before sudden decompensation occurs.
• Behavioral changes in children often precede changes in vital signs.
• Assessment relies heavily on observation rather than solely on diagnostic tests.

Role of the Pediatric Nurse

• Primary assessor of subtle physiologic and behavioral cues in pediatric patients.
• Advocate for patient safety, prioritizing the needs of pediatric patients.
• Partner with parents and caregivers to create a supportive care environment.
• Educate families and children about health promotion and disease prevention.
• Protect the pediatric environment to ensure safety and comfort.
• Act as an early recognizer of clinical deterioration in pediatric patients.

Family-Centered Care

• Parents are essential members of the healthcare team in pediatric nursing.
• Parents possess intimate knowledge of their child's baseline behavior and health patterns.
• Including parents in the assessment process improves accuracy and understanding.
• Shared decision-making supports safe and effective care decisions.
• Cultural beliefs and values influence pediatric care practices.
• The presence of parents reduces anxiety and distress in children undergoing treatment.

Atraumatic Care

• Minimize physical pain during procedures to enhance the child’s experience.
• Reduce fear and anxiety associated with healthcare encounters.
• Prevent unnecessary separation from caregivers during medical procedures.
• Use developmentally appropriate communication techniques to explain interventions to children.
• Provide choices when possible to empower children in their care.
• Preserve trust in the healthcare system by ensuring respectful and caring interactions.

Children are Not Small Adults

• Immature organ systems in children can affect assessment findings.
• Higher metabolic demands in children increase requirements for oxygen and fluids.
• Smaller physiologic reserves limit the child’s ability to compensate for illness.
• Compensation may mask deterioration until significant clinical changes occur; children can rapidly transition from stable to unstable.

Physiological Differences

Priority in Pediatrics

• Most pediatric emergencies involve respiratory compromise; early recognition of respiratory issues is critical to prevent deterioration.
• Respiratory failure is a common cause of cardiac arrest in pediatric patients.
• The work of breathing should be a primary focus during assessment.

Respiratory Anatomy Differences

• The narrower airway diameter in children increases the risk of obstruction.
• Children have a larger tongue size relative to the oral cavity.
• The trachea is shorter and softer in children compared to adults.
• Infants have fewer alveoli, impacting gas exchange.
• Horizontal ribs limit chest expansion during respiration.
• Even small amounts of edema can lead to significant airflow reduction.

Respiratory Physiology Differences

• Children exhibit a higher baseline respiratory rate than adults.
• Infants rely predominantly on diaphragm-dependent breathing.
• Limited ability of children to increase tidal volume may lead to rapid fatigue during respiratory distress.
• Higher oxygen consumption per kilogram in children increases their risk during distress situations.
• Hypoxia can develop quickly in pediatric patients due to the factors listed above.

Early Signs of Respiratory Distress

• Tachypnea (often the first observable sign).
• Nasal flaring.
• Mild to moderate retractions (notable in the chest).
• Restlessness or irritability exhibited by the child.
• Decreased feeding or activity levels, signaling discomfort or distress.
• Increased work of breathing, indicating the child is struggling.

Late Signs of Respiratory Distress

• Grunting, which indicates the child is trying to increase end-expiratory pressure to improve oxygenation.
• Stridor or severe wheezing suggests significant airway obstruction or bronchospasm.
• Cyanosis observed in the lips or extremities, indicating poor oxygenation.
• Decreased level of consciousness may indicate severe hypoxia or respiratory failure.
• Apnea or irregular respirations suggest imminent respiratory arrest.
• The occurrence of these late signs indicates high risk for respiratory arrest.

Retractions and Severity

• Subcostal retractions indicate mild distress.
• Intercostal retractions indicate moderate distress.
• Suprasternal retractions indicate severe distress.
• The worsening location of retractions reflects the worsening condition of the child.

Cardiovascular Differences

• Children have a higher resting heart rate compared to adults.
• Infants exhibit lower baseline blood pressure.
• Cardiac output in children is primarily dependent on heart rate due to smaller stroke volume.
• Hypotension is often a late sign of shock in children, indicating advanced decompensation.

Pediatric Compensation Patterns

• Tachycardia is an early sign of physiological stress in children.
• Peripheral vasoconstriction helps maintain blood pressure during compensatory states.
• Normal blood pressure in a child does not always indicate physiological stability; it can mask underlying issues.
• Bradycardia may serve as a pre-arrest sign in pediatric patients.
• Changes in perfusion often precede changes in blood pressure during decompensation.

Perfusion Assessment

• Capillary refill greater than 2 seconds indicates poor peripheral perfusion.
• Cool extremities suggest inadequate blood flow.
• Pale or mottled skin suggests compromised perfusion.
• Weak peripheral pulses indicate diminished circulation.
• Altered mental status, such as increased lethargy or decreased alertness, may signify systemic compromise.

Early vs Late Shock

• Early Shock:

  • Tachycardia (elevated heart rate).
  • Delayed capillary refill (greater than 2 seconds).
  • Mottling of the skin, indicating compromised perfusion.
  • Cool extremities reflecting altered circulatory status.
  • Irritability because of inadequate perfusion or oxygen delivery.

• Late Shock:

  • Hypotension, indicating significant circulatory failure.
  • Weak pulses due to decreased cardiac output.
  • Decreased urine output as a sign of renal compromise.
  • Altered level of consciousness as a result of severe systemic failure.

Fluid and Electrolyte Differences

• Children have a higher total body water percentage, making them more prone to dehydration.
• They also possess a larger extracellular fluid compartment.
• Immature kidney function impairs their ability to concentrate urine.
• There is a high risk for rapid dehydration due to various physiological factors.

Why Children Dehydrate Quickly

• Fever increases insensible fluid losses throughout the body.
• Vomiting and diarrhea lead to rapid fluid loss and can cause significant fluid imbalance quickly.
• Poor oral intake exacerbates dehydration, especially in ill children.
• Higher metabolic rate increases fluid requirements.
• Dehydration can develop in hours, not days as seen in adults.

Signs of Dehydration

• Fewer wet diapers or decreased urine output, particularly in infants.
• No tears when crying, indicating significant hydration status decline.
• Dry mucous membranes as a clinical sign of dehydration.
• Sunken fontanelle in infants indicates severe dehydration.
• Lethargy or irritability in children suggests worsening clinical status.
• Tachycardia arises as the body attempts to compensate for fluid loss.

Neurologic Differences

• Children possess a large head-to-body ratio, impacting balance and stability.
• Open fontanelles in infants allow for growth but can be an area of concern if bulging or sunken.
• Immature myelination results in differences in neurological function and development.
• Behavioral changes in children are direct reflections of their neurologic status.
• Children have a higher risk for seizure activity during illness.

Neurologic Red Flags

• Lethargy or difficulty to arouse from a state of unresponsiveness.
• Inconsolable high-pitched crying indicating possible distress or pain.
• Seizure activity, either observed or reported by caregivers.
• Bulging fontanelle in infants can indicate increased intracranial pressure.
• Sudden behavior changes may signal serious neurologic issues.

Immune System Differences

• Pediatric patients have an immature immune response compared to adults.
• They are more susceptible to infections due to their developing immune systems.
• Symptoms of infection may be subtle and not as robust as in adults.
• Fever responses vary by age; infants may not present with high fever even in serious illness.

Skin Differences

• Infants and young children exhibit a thinner epidermis than adults, leading to increased fluid loss.
• The absorption of topical medications is increased due to thinner skin.
• Higher burn risks in children due to sensitive skin and immature barrier function.
• Skin can be a direct reflection of perfusion and hydration status.

Medication Metabolism Differences

• Children have immature liver metabolism, impacting drug processing.
• Immature renal excretion affects how medications are cleared from the body.
• Weight-based dosing is essential for ensuring safety and efficacy in pediatric medications.
• There exists a narrow margin of safety for medication dosing in pediatric patients, heightening the risk for errors.
• Medication errors in the pediatric population can have severe consequences.

Pediatric Assessment Principles

• Observational assessments should occur before any physical contact; this minimizes discomfort.
• Follow a sequence from least invasive to most invasive during assessments.
• Employ a developmentally appropriate approach tailored to each child's developmental stage.
• Involvement of caregivers during assessments enhances the process and promotes trust.
• Compare assessment findings to age-based norms to ensure accurate evaluation.

Observation as an Assessment Tool

• General appearance is critical to assessing pediatric patients.
• Interaction level with the environment reflects engagement and health.
• Activity level can indicate wellness or distress.
• Work of breathing is closely monitored during the assessment.
• Cry or speech quality can provide important cues about the child's condition.

Developmentally Appropriate Assessment Techniques

• Infants: Assess while the infant is calm with a caregiver present to reduce stress.
• Toddlers: Offer choices to engage them and prepare for potential resistance.
• Preschoolers: Utilize play and demonstration as methods for assessment.
• School-age children: Explain steps of the assessment to promote understanding and participation.
• Adolescents: Ensure privacy and respect autonomy during assessment to facilitate honest communication.

Pediatric Assessment Triangle (PAT)

• A rapid assessment tool aimed at determining stability based on three components: appearance, work of breathing, and circulation to the skin.
• Each component plays a crucial role in assessing whether a child is stable or needs immediate intervention.

Vital Sign Trends by Age

• Heart rate decreases with age; clinical context is necessary for interpretation.
• Respiratory rate decreases with age; variations are normal within specific ranges.
• Blood pressure increases with age; monitoring must be contextually relevant.

Measuring Pediatric Vital Signs

1. Count heart rate (HR) and respiratory rate (RR) for a full minute in infants to ensure accuracy.
2. Use an appropriate cuff size when measuring blood pressure to obtain valid readings.
3. Document the child's emotional state (e.g., crying or distressed) when taking vital signs.
4. Reassess any abnormal findings to monitor for changes over time.

Interpreting Pediatric Vital Signs

1. Consider age-based norms when interpreting vital signs.
2. Assess vital signs alongside appearance and behavior for a comprehensive evaluation.
3. Identify and interpret trends over time rather than focusing on isolated values.
4. Understand that a single vital sign value requires contextual interpretation to understand its significance.

Pediatric Pain Assessment

• Children experience pain similarly or even more intensely than adults; effective assessment is crucial.
• Pain expression varies by age; younger children may not articulate pain well.
• Behavioral cues are clinically significant and should be closely monitored during assessments.
• Use validated pain assessment scales tailored to pediatric populations for accuracy.

Pediatric Red Flags

• Children can often compensate for physiological issues before showing clinical deterioration.
• Late signs of illness can indicate severe physiologic compromise; early recognition can save lives.
• Nurses play a critical role in escalating care promptly when red flags are identified.

Respiratory Red Flags

• Stridor: indicative of upper airway obstruction.
• Grunting: suggestive of respiratory distress and impaired gas exchange.
• Severe retractions: indicate significant respiratory distress and potential failure.
• Cyanosis: indicates severe oxygen deprivation.
• Apnea: cessation of breathing, which can be life-threatening.
• Head bobbing: a sign that a child is struggling to breathe effectively.

Hydration Red Flags

• No urine output: necessitates immediate evaluation for dehydration or renal impairment.
• Persistent vomiting: can lead to rapid dehydration requiring intervention.
• Poor oral intake: can exacerbate already present dehydration.
• Sunken fontanelle in infants suggests significant fluid loss and requires prompt attention.

Dehydration and Fluid Replacement

Degree of Dehydration

• Mild: 5% for infant/young child; 3% for older child/adolescent.
• Moderate: 10% for infant/young child; 6% for older child/adolescent.
• Severe: ≥ 15% for infant/young child; ≥ 9% for older child/adolescent.

Clinical Signs of Dehydration

• Heart Rate: Normal to rapid in mild; rapid in moderate; markedly decreased in severe.
• Blood Pressure: Normal in mild to moderate; hypotension in severe.
• Urine Output: Normal in mild; decreased in moderate; anuria in severe.
• Mucous Membranes: Moist in mild; dry in moderate; markedly dry in severe.
• Fontanelles: Normal in mild; sunken in moderate; markedly sunken in severe.
• Capillary Refill: Normal (

Management of Dehydration

• Oral Rehydration: Use dilute juice or oral rehydration solutions.
• Continue age-appropriate diet as tolerated.
• Children ≥6 months can receive 0.15 mg/kg of Ondansetron (max dose 8 mg) for vomiting.
• If oral rehydration is ineffective, transition to IV hydration.

4-2-1 Rule for IV Fluids

• For the first 10 kg, administer 4 mL/kg.
• For the next 10 kg (10-20 kg), administer 40 mL + 2 mL/kg.
• For children >20 kg, administer 60 mL + 1 mL/kg.

Calculating IV Fluids

1. Step 1: Bolus = Normal Saline (NS) 10-20 mL/kg or 5-10 mL/kg if concerned about myocardial or renal dysfunction.
2. Step 2: Calculate the deficit = % dehydrated x weight in kg.
3. Step 3: Calculate maintenance fluids in mL/hr using the 4-2-1 rule.
4. Step 4: Calculate the Total Fluid Replacement over 24 hours = deficit + maintenance - bolus.
5. Step 5: Divide the total volume over 24 hours to determine hourly infusion rates.
6. Step 6: Measure ongoing losses (e.g., from continuous vomit, diarrhea, or sweat) and replace as necessary.
7. Step 7: IV fluid selection typically is D5NS +/- 20 mEq/L KCl, dependent on kidney function and electrolyte levels.

Example Case

• An 18 kg child with 9% dehydration:
• Bolus: 20 mL/kg x 18 kg = 360 mL
• Deficit: 0.09 x 18 kg = 1.62 L
• Maintenance Fluid Calculation: 40 mL + 2(8 kg) = 56 mL/hr
• Total Fluid Replacement Required: 1620 mL + (56 mL x 24) - 360 mL = 2604 mL.
• Dividing Volume over 24 hours: 2604 mL / 24 hr = 108.5 mL/hr
• Ensure to replace losses as needed and consider IV fluid as D5NS +/- 20 mEq/L KCl.

Perfusion Red Flags

• Delayed capillary refill time (greater than 2 seconds).
• Cool or mottled skin suggests peripheral vasoconstriction and poor perfusion.
• Weak peripheral pulses necessitate assessment for cardiac output.
• Hypotension is a late sign of insufficient perfusion and advanced shock.
