6 Pediatric Emergency Practice Cases

A repeatable emergency approach

Pediatric emergencies can deteriorate quickly, and early signs may be subtle. Use a repeatable sequence: make a rapid visual assessment, perform ABCDE, treat life threats as they are identified, and reassess frequently.

These cases are educational examples, not a substitute for current local protocols, clinician judgment, or medical direction.

Rapid assessment and team response

Begin from the doorway with the Pediatric Assessment Triangle (PAT), considering appearance, work of breathing, and circulation to the skin. An abnormality in any component raises concern; abnormalities in multiple components indicate greater urgency. This rapid impression does not replace a full assessment.

Proceed through ABCDE: airway, breathing, circulation, disability (neurologic status and glucose when indicated), and exposure or environment. Treat immediately dangerous problems as they are found; do not wait to finish the entire examination.

Obtain age-appropriate respiratory rate, heart rate, oxygen saturation, blood pressure, temperature, mental status, and perfusion. Interpret observations by age and trend them over time. Children may maintain blood pressure despite worsening shock, so hypotension can be a late sign.

Call for help early, assign team roles, and involve the caregiver when possible. Select equipment and medication doses according to measured or carefully estimated weight and local protocol. Reassess after every intervention, recording whether breathing effort, mental status, pulses, skin perfusion, vital signs, and pain improve or worsen.

Infant with respiratory distress

A 5-month-old with two days of runny nose and cough has increasing difficulty feeding. The infant is alert but fussy, breathing rapidly, with nasal flaring and chest retractions. The hands are warm and the lips are not blue.

The abnormal work of breathing on PAT calls for prompt assessment and close observation. Obtain age-appropriate vital signs and pulse oximetry. Ask about onset, feeding, wet diapers, choking, fever, prematurity, and relevant medical history.

Keep the infant with the caregiver when feasible, position to support the airway, minimize agitation, and clear nasal secretions if they obstruct breathing. Provide oxygen or other respiratory support as indicated by the clinical picture and local protocol.

Watch for worsening fatigue, reduced responsiveness, poor air movement, apnea, cyanosis, or slowing respiratory effort. These can signal respiratory failure even if visible effort seems to lessen. If the infant deteriorates, escalate support and summon advanced help promptly. Assess feeding and hydration after immediate breathing concerns are addressed, and avoid forcing oral intake when breathing is significantly compromised.

Infants have small airways and limited respiratory reserve. Feeding difficulty, nasal flaring, and retractions can be signs of distress; a quieter, less responsive infant is not necessarily improving.

Toddler with infection and poor perfusion

A 2-year-old with fever and vomiting is unusually sleepy, pale, and has cool hands, a fast weak peripheral pulse, and delayed capillary refill. Blood pressure is not low.

Shock is still possible. Tachycardia, weak pulses, cool skin, delayed refill, and altered behavior can indicate compensated shock before hypotension appears. Consider infection-related, fluid-loss, and other causes; the case findings alone do not establish one diagnosis.

Call for help and begin ABCDE. Support oxygenation and ventilation as needed, obtain monitoring and vascular access, and check glucose when indicated. While stabilizing the child, look for the source of illness and evidence of ongoing fluid loss.

Give fluids or vasoactive support only according to the suspected cause, the child’s response, and local pediatric resuscitation guidance. Reassess frequently for improving perfusion and signs of fluid intolerance, such as increasing respiratory effort or new crackles. Escalate care if perfusion or mental status worsens.

Do not interpret a single capillary-refill measurement or blood-pressure reading in isolation; consider the whole presentation and its trend. Young children may compensate for circulatory compromise for a time. A normal-looking blood pressure does not rule out shock, and worsening mental status or weak central pulses signals severe deterioration.

Child injured in a collision

An 8-year-old struck by a vehicle is anxious and has chest bruising, fast labored breathing, cool skin, and a small bleeding wound on the thigh. The mechanism raises concern for neck and internal injuries.

Activate the trauma response appropriate to the setting. Maintain spinal motion restriction when indicated by the mechanism and examination, while prioritizing airway and breathing. Control external bleeding promptly with direct pressure or other protocol-directed measures.

Assess chest movement, breath sounds, oxygenation, pulses, mental status, and signs of impaired perfusion. Suspect significant internal injury when the mechanism and physiology warrant it: external bleeding may be only part of the problem, and a small external wound neither explains nor excludes serious blood loss. Treat immediately life-threatening chest or airway conditions according to trained scope and protocol.

Keep the child warm, establish monitoring and vascular access, and prepare for rapid transport or transfer to an appropriate trauma center. For suspected hemorrhagic shock, activate the relevant resuscitation pathway. Blood products may be preferred for ongoing resuscitation when available and appropriate under local protocol.

After immediate threats are addressed, perform a systematic head-to-toe assessment, obtain relevant history from the child and caregiver, provide age-appropriate explanations and analgesia, and reassess after each intervention. Children may initially maintain blood pressure despite significant blood loss; use perfusion, mental status, pulse quality, mechanism, and trends—not hypotension alone—to identify deterioration.

Adolescent with breathing difficulty after injury

A 15-year-old has shortness of breath and chest pain after a fall. The adolescent is frightened, answers questions briefly, and has a caregiver present who reports no known medical history.

Begin with PAT and ABCDE. Explain each step in plain language and include the adolescent in decisions appropriate to their developmental level. Ask the caregiver for useful history, while also providing an appropriate opportunity to speak privately with the adolescent when feasible and consistent with safety and local policy.

Assess for injury and respiratory compromise; do not assume anxiety is the cause of breathing difficulty. Provide indicated stabilization, pain care, and monitoring under local protocol. Ask about medications, allergies, relevant conditions, and the event. Reassess breathing, circulation, mental status, and pain, and communicate important changes during handoff.

Adolescents may have near-adult body size but still need pediatric-appropriate communication, privacy, safeguarding, and assessment of developmental needs.

Applying the approach across cases

Respiratory distress can progress to failure. Fatigue, altered responsiveness, apnea, or poor air movement call for urgent escalation. In infants, reduced visible effort or a quieter presentation does not necessarily mean improvement.

Children can be in shock before hypotension develops. Interpret perfusion, mental status, vital signs, and trends together, and consider internal injury in trauma when mechanism and physiology warrant it.

In trauma, control bleeding, address airway and breathing threats promptly, protect against heat loss, and follow the relevant resuscitation pathway. Adapt equipment, communication, examination, and caregiver involvement to the child’s age and developmental needs.

Reassessment is part of treatment: check the child’s response after every intervention and escalate when perfusion, mental status, or breathing worsens.
