Chest Trauma

Unit 5 · Topic 26Chest Trauma
1.Overview & Pathophysiology

Chest (thoracic) trauma is a major cause of trauma deaths. It is classified as blunt (motor vehicle and motorcycle crashes, falls, assaults — most common) or penetrating (stab and gunshot wounds). Injuries threaten life by three main routes: hypoxia (airway or lung injury), hypovolemia (bleeding into the chest), and impaired cardiac function (tamponade, tension pneumothorax, cardiac injury). Most chest injuries are managed with oxygen, analgesia, and a chest tube; a minority need surgery.

InjuryMechanism and key facts
Rib fracturesMost common chest injury; pain limits breathing → atelectasis and pneumonia. Older adults are at especially high risk of complications. Fractures of ribs 1–2 suggest high force (great vessel injury); lower ribs → liver or spleen injury
Flail chestTwo or more adjacent ribs each fractured in two or more places (some trauma guidelines use three or more) → a free segment moves paradoxically (in on inspiration, out on expiration). The underlying pulmonary contusion is the main cause of hypoxemia
Pulmonary contusionBruising and bleeding into lung tissue; worsens over 24–72 hours; can progress to pneumonia and ARDS
Pneumothorax (simple, open, tension)Air in the pleural space; see Pneumothorax topic
HemothoraxBlood in the pleural space from lung, intercostal, or great vessel injury; massive hemothorax causes hypovolemic shock
Cardiac tamponadeBlood in the pericardial sac compresses the heart → obstructive shock
Blunt cardiac injuryDysrhythmias, wall-motion abnormalities, rarely rupture
Blunt thoracic aortic injuryRapid deceleration tears the aorta, usually just beyond the left subclavian artery; most victims die at the scene
Tracheobronchial injuryLarge continuous air leak, persistent pneumothorax despite a chest tube, extensive subcutaneous emphysema
Diaphragmatic ruptureAbdominal organs herniate into the chest (bowel sounds heard in the chest), more often on the left
2.Assessment Findings

Primary survey — find and treat immediate life threats in order (many trauma systems control massive external bleeding first): Airway with cervical spine protection, Breathing, Circulation, Disability, Exposure.

InjuryKey findings
Rib fracturesLocalized pain and tenderness worse with breathing, shallow splinted breathing, crepitus
Flail chestParadoxical chest wall movement, severe pain, dyspnea, hypoxemia
Pulmonary contusionIncreasing dyspnea, hypoxemia, crackles, hemoptysis over hours to days
Simple pneumothorax↓/absent breath sounds, hyperresonance, subcutaneous emphysema
Tension pneumothoraxHypotension, tachycardia, JVD, tracheal shift to the opposite side, absent breath sounds
Open pneumothoraxSucking sound at the wound, bubbling blood
Hemothorax↓breath sounds, dullness to percussion, signs of hypovolemic shock; X-ray may show fluid or an air-fluid level (hemopneumothorax)
Cardiac tamponadeBeck's triad: hypotension, distended neck veins, muffled heart sounds; pulsus paradoxus (> 10 mmHg fall in systolic BP on inspiration); PEA
Aortic injuryChest or back pain, unequal arm pulses or BP, hypotension; widened mediastinum on X-ray

Also assess: pain score, SpO₂, ABG, level of consciousness, skin color, seat-belt or steering-wheel bruising, associated abdominal and head injuries.

3.Diagnostics
TestUse
eFAST (extended focused assessment with sonography in trauma)Rapid bedside detection of pericardial fluid, hemothorax, pneumothorax, abdominal bleeding
Chest X-rayFractures, pneumothorax, hemothorax, widened mediastinum
CT chest; CT angiography (CTA)CTA is the primary diagnostic test for blunt aortic injury — it has replaced catheter aortography in most trauma centers
ECG, troponinScreen for blunt cardiac injury
ABGRespiratory acidosis (↓pH, ↑PaCO₂) with hypoxemia = impending respiratory failure (e.g., flail chest with contusion)
CBC, type and crossmatch, lactate, coagulation testsBlood loss, shock, coagulopathy
4.Medical Management
  • Oxygen; airway management and positive-pressure ventilation (noninvasive or intubation) for respiratory failure
  • Tension pneumothorax: immediate needle or finger decompression, then chest tube
  • Open pneumothorax: vented chest seal or three-sided dressing, then chest tube
  • Hemothorax: chest tube — traditionally large-bore; small-bore catheters are acceptable in stable clients (the drained blood may be autotransfused). Indications for surgical exploration (thoracotomy): initial drainage ≥ 1,500 mL, or ≥ 200 mL/hour for 2–4 hours, or ongoing need for transfusion
  • Hemorrhagic shock: two large-bore IVs or intraosseous access; balanced blood product resuscitation rather than large volumes of crystalloid; tranexamic acid within 3 hours of injury where protocols apply (risks: thrombosis, seizures)
  • Cardiac tamponade: pericardiocentesis as a bridge; definitive surgical repair (thoracotomy/sternotomy)
  • Flail chest and rib fractures: multimodal analgesia is the cornerstone — scheduled acetaminophen, opioids, regional techniques (epidural, paravertebral, or serratus plane blocks), sometimes ketamine; ventilatory support as needed; surgical rib fixation for selected clients. External binding or taping of ribs is no longer used — it restricts breathing
  • Pulmonary contusion: oxygen, pulmonary hygiene, avoid fluid overload while maintaining perfusion
  • Blunt aortic injury: control heart rate (target about < 100/min) and systolic BP (about < 100–120 mmHg, as ordered) with short-acting IV beta-blockers (e.g., esmolol) to reduce wall stress; endovascular repair (TEVAR) is preferred for most
  • Impaled objects: stabilize in place; remove only in the operating room
  • Tetanus prophylaxis for penetrating wounds

Drug safety

  • Opioids: respiratory depression, sedation, hypotension, constipation — monitor RR and sedation scale; naloxone available
  • NSAIDs: bleeding, kidney injury, GI ulceration — avoid in active bleeding, hypovolemia, kidney injury
  • Local anesthetics for blocks/epidurals: watch for local anesthetic systemic toxicity — perioral numbness, metallic taste, tinnitus, seizures, dysrhythmias; lipid emulsion is the antidote. Epidural: hypotension, motor block; check anticoagulant timing
  • Ketamine: hypertension, tachycardia, emergence reactions
  • Esmolol: bradycardia, hypotension, bronchospasm
5.Nursing Interventions

Listed in priority order.

  1. Airway with cervical spine protection
  2. Breathing
    • High-concentration oxygen (e.g., non-rebreather mask at 10–15 L/min) for the injured, hypoxemic client; titrate once stable
    • Continuous SpO₂, RR, breath sounds, chest wall movement
    • Recognize tension pneumothorax and prepare for immediate decompression
    • After placing a three-sided dressing on an open wound, monitor closely for tension pneumothorax; if signs develop, lift one edge of the dressing to release air and notify immediately
  3. Circulation
    • Two large-bore IVs, draw type and crossmatch, warm blood products and fluids, prevent hypothermia
    • Monitor BP, heart rate, urine output, lactate
    • Chest tube output: report promptly any sudden increase or bright red drainage (commonly > 100 mL/h, or per provider threshold); initial drainage ≥ 1,500 mL or ≥ 200 mL/h for 2–4 hours indicates the need for surgery — notify immediately
    • Watch for Beck's triad and prepare for pericardiocentesis
  4. Pain control — scheduled, multimodal; reassess pain and sedation; good analgesia is what makes effective breathing possible
  5. Pulmonary hygiene
    • Semi- to high-Fowler's position when spine is cleared
    • Incentive spirometry, deep breathing, and coughing with splinting (pillow held against the chest)
    • Early mobilization
  6. Chest tube care — see Pneumothorax topic; continuous large bubbling in the water seal after trauma may indicate major airway injury — report immediately
  7. Psychosocial support; assess for other injuries and for abuse or violence where relevant
6.Client Education
  • Rib fractures: take pain medication on schedule so you can breathe deeply; use the incentive spirometer for 10–15 breaths every 1–2 hours while awake, or as ordered; hold a pillow against the chest to cough
  • Do not wrap or bind the chest
  • Report fever, productive cough, worsening shortness of breath, or increasing chest pain (pneumonia, delayed pneumothorax or hemothorax)
  • Avoid heavy lifting, contact sports until cleared
  • Opioid safety: no driving, no alcohol or sedatives, prevent constipation
  • Injury prevention: seat belts, motorcycle helmets and protective gear, fall prevention for older adults
7.Complications & Red Flags
ComplicationWhat to watch for
Tension pneumothoraxHypotension, JVD, tracheal shift, absent breath sounds
Massive hemothorax / hemorrhagic shockHypotension, tachycardia, high chest tube output, dullness to percussion
Cardiac tamponadeBeck's triad, pulsus paradoxus
ARDS (after contusion, flail chest, transfusion)Worsening hypoxemia over 24–72 hours, bilateral infiltrates
Acute respiratory failureRespiratory acidosis, hypoxemia, fatigue
Pneumonia, atelectasisFever, new crackles — especially with poorly controlled pain
DysrhythmiasAfter blunt cardiac injury
Empyema, retained hemothoraxFever, persistent opacity
Fat embolism (with long-bone fractures)Hypoxemia, confusion, petechiae 24–72 hours after injury
8.High-Yield Points
  • Primary survey: airway with C-spine, breathing, circulation — treat life threats as found
  • Flail chest = ≥ 2 adjacent ribs broken in ≥ 2 places → paradoxical movement; the underlying contusion causes hypoxemia
  • Pulmonary contusion worsens over 24–72 h and can lead to ARDS
  • Air-fluid level + shock after trauma → hemothorax, the most urgent problem
  • Massive hemothorax: ≥ 1,500 mL initially or ≥ 200 mL/h for 2–4 h → surgery
  • Beck's triad = hypotension, JVD, muffled heart sounds → tamponade
  • Tension pneumothorax → decompress immediately; after a three-sided dressing, watch for tension
  • Blunt aortic injury: CT angiography is the diagnostic standard; control HR and BP
  • Respiratory acidosis + hypoxemia on ABG = respiratory failure
  • Priority nursing diagnosis for open chest wound with dyspnea: impaired gas exchange
  • Rib fractures: multimodal analgesia, incentive spirometry, no rib binding
  • Continuous heavy bubbling in the water seal after trauma → large air leak — report immediately

Country Notes

United States

  • Trauma care is organized by verified trauma center levels (Level I–IV); severely injured clients are transferred to the highest-level center available.
  • Many trauma nurses complete the Trauma Nursing Core Course (TNCC), which follows the same primary survey approach.

Philippines

  • Motorcycle crashes are a leading cause of blunt chest trauma; the Motorcycle Helmet Act (RA 10054) requires helmets for riders.
  • Blood product availability varies by facility; early coordination with the blood bank or Philippine Red Cross blood service may be required for transfusion.
