6.3 Thoracic & Airway Trauma and Thoracic Surgery
Key Takeaways
- Pediatric rib fractures require significant force or non-accidental trauma evaluation; underlying lung contusion, pneumothorax, or hemorrhage may be more dangerous than the fracture itself.
- Pulmonary contusion worsens over 24–48 hours with progressive hypoxemia; supportive care and judicious fluids limit secondary injury.
- Tracheal or bronchial injury presents with persistent air leak, subcutaneous emphysema, pneumomediastinum, or failed lung expansion — protect the airway and escalate to surgical/ENT/trauma teams early.
- Tension pneumothorax is a clinical diagnosis: unilateral absent sounds, hypotension, and contralateral tracheal deviation demand immediate decompression before imaging.
- Post-thoracic surgery PICU care prioritizes chest-tube patency, pain control for effective cough, respiratory toilet, and early recognition of bleeding, air leak, and arrhythmias.
Pediatric Thoracic Trauma: High Force, High Stakes
Children have pliable ribs and mediastinal mobility, so external chest wall injury may look modest while underlying visceral injury is severe. Significant thoracic trauma in a child implies high-energy transfer — vehicle collision, fall, crush, or, in infants and toddlers, possible non-accidental trauma. The CCRN Pediatric nurse must recognize evolving respiratory failure, life-threatening pleural collections, and airway disruption while preparing for operative thoracic care.
Rib Fractures
Because pediatric ribs bend before they break, rib fractures often signal major force. Multiple fractures, especially posterior fractures in young children, warrant careful evaluation for abuse when the history is inconsistent. Clinical concerns: splinting, shallow breathing, hypoventilation, and associated injuries (lung, liver, spleen). Management is primarily supportive — oxygen, pulmonary hygiene, and multimodal analgesia so the child can breathe deeply — not routine operative fixation. Watch for delayed pneumothorax and progressive contusion beneath the fracture site.
Pulmonary Contusion
Pulmonary contusion is bruising and alveolar hemorrhage within the lung parenchyma. Hypoxemia may be mild at presentation and worsen over 24–48 hours as inflammation and edema peak. Findings include tachypnea, crackles or diminished sounds, hemoptysis in some cases, and infiltrates on imaging that may lag clinical decline. Care priorities: supplemental oxygen or ventilatory support as needed, avoidance of fluid overload, lung-protective ventilation if intubated, pulmonary toilet, and monitoring for ARDS evolution. Aggressive crystalloid resuscitation after trauma can worsen contusion edema — collaborate on goal-directed fluid strategy.
Tracheal and Bronchial Injury
Tracheobronchial injury may follow blunt deceleration or penetrating trauma, or rarely traumatic intubation. Red flags:
- Massive or persistent subcutaneous emphysema of neck/chest
- Pneumomediastinum
- Continuous large air leak from a chest tube with failure of lung re-expansion
- Hemoptysis, voice change, or refractory hypoxemia
- "Fallen lung" sign or persistent pneumothorax despite adequate drainage
Nursing actions: high-flow oxygen, minimize positive-pressure trauma when possible until the airway is secured by an experienced team, keep the head midline, prepare for emergent operative repair or selective intubation distal to the injury, and never repeatedly "force" a difficult airway without surgical backup when tracheal transection is suspected.
Pneumothorax and Hemothorax Recognition
Simple vs Tension Pneumothorax
Air in the pleural space collapses lung tissue. A tension pneumothorax adds progressive pressure that shifts the mediastinum, kinks great veins, and drops cardiac output. Recognize tension clinically:
- Severe distress or sudden ventilator deterioration
- Absent or markedly decreased breath sounds on one side
- Hyperresonance (air) on that side
- Tracheal deviation away from the injured side
- Hypotension, tachycardia, jugular venous distention
Treatment is immediate needle decompression followed by tube thoracostomy — do not delay for chest radiograph confirmation in an unstable child.
Hemothorax
Hemothorax is blood in the pleural space. Signs: dullness to percussion, decreased sounds, hypovolemia out of proportion to external bleeding, and opacification on imaging. Large pediatric hemothorax may require chest tube drainage and volume resuscitation; ongoing bloody output (per trauma/surgery thresholds) signals need for operative exploration. Autotransfusion systems or massive transfusion protocols may be activated in severe hemorrhage.
| Condition | Percussion | Key instability clues | Immediate priority |
|---|---|---|---|
| Tension pneumothorax | Hyperresonant | Shock + contralateral tracheal shift | Needle decompression → chest tube |
| Hemothorax | Dull | Shock + dullness/opacification | Chest tube, volume, surgical control |
| Pulmonary contusion | Often resonant early | Progressive hypoxemia over hours | Support O2/ventilation, limit fluids |
| Airway disruption | Variable | Persistent air leak, SQ emphysema | Expert airway + surgical consult |
Post-Thoracic Surgery PICU Care
After thoracotomy, VATS, lung resection, repair of tracheobronchial injury, or chest wall procedures, nursing care focuses on drainage, oxygenation, pain, and bleeding.
Chest Tubes
- Maintain prescribed suction or water-seal status; never clamp a bubbling tube routinely without a specific order — clamping can convert an air leak into tension physiology.
- Assess output volume, color, and trends hourly initially. Sudden cessation may mean kink/clot; sudden gush of bright blood means hemorrhage.
- Keep tubing free of dependent loops that obstruct drainage; milk only if ordered by local protocol.
- Monitor for air leak grading and report new or increasing leaks after previously dry periods.
Respiratory and Pain Management
Incisional pain causes splinting and atelectasis. Use ordered multimodal analgesia (including regional techniques when present), incentive spirometry or age-appropriate deep-breathing games, early mobilization, and humidified oxygen. For intubated children, coordinate sedation so spontaneous breathing trials are not sabotaged by uncontrolled pain, yet oversedation does not erase cough.
Complications to Anticipate
- Bleeding into the chest or mediastinum with falling hematocrit and rising drain output
- Persistent air leak suggesting bronchopleural fistula
- Pneumonia / atelectasis from shallow breathing
- Arrhythmias after pericardial or mediastinal manipulation
- Chylothorax after certain mediastinal dissections (milky output when feeding)
- Recurrent laryngeal nerve injury with voice change or aspiration risk after airway surgery
Putting It Together for the Exam
A classic vignette: a restrained child in a motor vehicle collision arrives with mild tachypnea, then hours later develops worsening hypoxemia and infiltrates — pulmonary contusion evolving, not "just anxiety." Another: sudden hypotension and absent left breath sounds after positive-pressure ventilation — treat as tension pneumothorax. Postoperative: a fresh thoracotomy patient with a previously gentle air leak who becomes hypotensive after someone clamps the tube for transfer — unclamp and decompress physiology first. Across all scenarios, pediatric thoracic care rewards early pattern recognition and decisive escalation over watchful waiting when shock physiology appears.
An unstable pediatric trauma patient has absent breath sounds on the right, hypotension, and tracheal deviation to the left. What is the priority intervention?
A child with blunt chest trauma has a nearly normal admission chest film but progressive hypoxemia and infiltrates at 36 hours. Which injury pattern best explains this course?
After pediatric thoracotomy, which nursing action is most appropriate when a chest tube that was bubbling vigorously is clamped for transport and the child becomes hypotensive with rising airway pressures?
