Study Notes
Chest Injuries Overview
- Ventricular Fibrillation: Occurs when a significant impact to the chest happens during a critical cardiac cycle, leading to cardiac arrest.
- Flail Segment: Indicated by a flail chest section causing respiratory distress and low oxygen saturation; usually associated with pulmonary contusion.
- Open Pneumothorax: A wound allowing air movement into the pleural space during ventilation; poses hazards of hypoxia and respiratory distress.
Cardiovascular Complications
- Myocardial Contusion: Rapid and irregular pulse following blunt chest trauma suggests this cardiac injury, can lead to serious complications.
- Cardiac Tamponade Indicators: Assess for engorged jugular veins, especially in cases of trauma suggesting fluid accumulation around the heart.
Respiratory Symptoms & Assessments
- Respiratory Distress Signs: Includes shallow breathing, cyanosis, and hypotension indicative of shock; necessitate immediate ventilation support.
- Hemoptysis: Defined as coughing up blood, which can be indicative of serious lung or chest injury.
- Pleural Fluid Location: Found between the visceral and parietal pleurae, crucial for understanding fluid collection diseases.
Pneumothorax & Emergency Response
- Tension Pneumothorax Symptoms: Includes absent breath sounds on affected side, severe cyanosis, and altered mental status; immediate needle decompression is critical for treatment.
- Subcutaneous Emphysema: Presence indicates air leaking into tissues from a lung injury.
- Ventilation Risks: High caution when managing positive-pressure ventilation in cases of pneumothorax to avoid worsening the injury.
Examination Findings
- Shock Symptoms: Signs such as hypotension and tachycardia indicate possible internal bleeding like hemothorax.
- Laceration of Aorta: High suspicion for this injury in unrestrained motor vehicle accident patients presenting with significant shock and altered consciousness.
Management Protocols
- Open Wound Care: In cases of open chest wounds, maintain a seal but be ready to partially remove the dressing if respiratory distress increases.
- Immediate ALS Support: Essential for patients with severe labored breathing and significant chest trauma for advanced airway management.
Anatomy and Functionality
- Intercostal Muscle Function: Contraction during inhalation elevates the rib cage, essential for effective breathing mechanics.
- Supine Breathing Mechanics: Diaphragm position may rise to the nipple line during exhalation, complicating trauma assessments.
Additional Signs
- JVD and Hemothorax: Jugular venous distention may indicate large volume blood loss and pressure changes within the thoracic cavity, vital for assessment of traumatic injuries.
Use these notes as quick references for understanding chest injuries, their indications, assessments, and emergency protocols.
