Chest Trauma Espanola Valley Emergency Medical Services Espanola, NM
Factoids • 25% of trauma deaths • 10% require surgery
Classifications • By mechanism • penetrating • blunt • By injury
The chest - what’s in there? • Chest wall • Pleura • Lungs • Mediastinum • Diaphragm
Key Anatomy review • Define the limits of the chest • Inspiration/expiration • Pleura/potential space • Neurovascular bundle • Pericardium
What can go wrong • Chest wall • Rib fractures • Flail chest • Sternal fracture • Why do we care? • Pain • Markers for underlying injury • Pain limited respiration
What can go wrong • Lungs • Pneumothorax • Open • Closed • Tension • Hemothorax • Hemopneumothorax • Pulmonary contusion • Michelin man syndrome
What can go wrong • Mediastinum • Myocardial contusion • Pericardial tamponade • Aortic dissection • Myocardial rupture/penetration • Espophageal rupture • Diaphragm • Rupture • Traumatic asphyxia
Pearls • Tension presents like tamponade • Both hypotension, neck vein distension and narrow pulse pressure • tension more common • tamponade usually with penetrating trauma • tension usually with blunt trauma • tamponade has normal lung sounds • you can treat tension • tamponade is going to the OR anyway
Pearls • Flail segment may not be initially visible • Beck’s triad • Children more prone to contusions and tension pneumothorax • Tracheal deviation with tension is rare • Each side of chest can hold 3 liters of blood in adult • Need long needle for thoracostomy
PPV Suspicions • Peak airway pressures > 50 cm H2O • PEEP > 15 cm H2O • ARDS, COPD, or asthma • Use of tidal volumes > 12 mL/kg
Prehospital Treatment • Recognition: H and P • Oxygenate: high flow O2, intubation, RSA • But beware of positive pressure • Maintain perfusion: crystalloids, blood • No M.A.S.T. • Release tension: needle decompression • Rapid transport to hospital
Needle Decompression • PPE • Assess the need • Clean and prep site ( 2ndintercostal space midclavicular) • Select appropiate size catheter • 12-14g 3 inch for adults, size appropiate for infants and children • Cook catheter
Needle Decompression • Monitor for rush of air and may measure with syringe. • Reassess for hemodynamic and oxygenation improvement. • Documentation • Indications/Procedure • Location • Results
ED treatment • Recognition: expensive tests • Oxygenate: high flow O2, intubation • Maintain perfusion: crystalloids and blood • Release tension: chest tube • Rapid transport to OR
