- Causes
- Chest Traumatic Injury
- High speed injury (e.g. MVA)
- Sternal Fracture
- History
- Bent stearing wheel in a Motor Vehicle Accident
- Symptoms
- Chest Pain
- Signs
- Hypotension
- Anterior chest wall injury
- Sternal Fracture signs
- Sternal tenderness
- Sternal deformity
- Labs
- Serial Troponin levels
- Standard Troponin at 4-6 hours or High Sensitivity Troponin at 3 hours after injury
- Diagnostics
- Telemetry monitoring
- Electrocardiogram (EKG) - obtain serial EKGs
- See EKG monitoring in Trauma
- Changes occur typically in first 8-24 hours of injury and typically resolve spontaneously
- Premature Ventricular Contractions (PVC)
- Unexplained Sinus Tachycardia
- Atrial Fibrillation (most common Arrhythmia)
- Right Bundle Branch Block
- ST Segment changes
- Myocardial Infarction may occur in blunt cardiac Trauma
- Advanced hemodynamic monitoring (if central access)
- Central Venous Pressure increased
- Imaging
- FAST Exam
- Pericardial Effusion may be present
- Echocardiogram
- Wall motion abnormality
- Right Ventricle is most commonly injured chamber in Sternal Fracture
- Evaluate for valvular injury
- Evaluation
- Normal Troponin, EKG, hemodynamic and cardiac monitoring without significant other Chest Injury
- Unlikely to have significant cardiac injury
- May be discharged home after 6 hour observation
- Abnormal Troponin, EKG hemodynamic or cardiac monitoring (esp. in displaced Sternal Fracture, other Chest Trauma)
- Complete full evaluation with Echocardiogram, telemetry, trauma Consultation
- Differential Diagnosis
- See Blunt Chest Trauma
- See associated conditions below
- Rib Fracture
- Associated Conditions
- See Blunt Chest Trauma
- Heart Injury
- Valve Rupture
- Coronary Artery Dissection
- Cardiac Chamber Rupture
- Cardiac Tamponade
- Commotio Cordis
- Other Chest Injury
- Lung Contusion
- Hemothorax
- Pneumothorax
- Traumatic Aortic Disruption
- Diaphragmatic Rupture
- Esophageal Rupture
- Bronchial Tear
- Management
- ABC Management
- Manage Hypoxia, Hypotension and identified complications
- Indications for observation (24-48 hour)
- See Evaluation above
- Complications (see below) are most likely to present in the first 24-48 hours
- Complications
- Cardiogenic failure
- Arrhythmia (including lethal, ventricular Arrhythmia)
