Trauma Overview David B. Reedy, M.D., FACEP Contra Costa Regional Medical Center Assistant Clinical Professor UCSF/SFGH
Trauma is an injury caused by a physical force • Motor vehicle collisions • Falls • Gun shot • Stabbing • Burns • Blunt assault
Advanced Trauma Life Support • American College of Surgeons • Provides a framework for the management of the injured patient • Intended to allow the single doctor in a rural hospital to assess and manage trauma patients
ATLS Origins • Nebraska, 1976 • Plane crash in a Nebraska field changed the face of trauma care throughout the world • Medical, EMS, and Nursing groups began to collate protocols for trauma management • ACS publishes ATLS in 1980
Blunt Thoracic Trauma • Airway • Look for associated injuries • Remember c-spine
Blunt Thoracic Trauma • Breathing • Respiratory rate • Paradoxical motion • Crepitus • Subcutaneous air • Auscultation
Blunt Thoracic Trauma • CXR-pneumothorax • Tracheal deviation, hypotension, hypoxemia
Blunt Thoracic Trauma • Circulation • Hypotension • Hypovolemia • Pneumothorax • Cardiac tamponade • Aortic Injury • Blunt cardiac injury • Arrhythmia • NSR
Blunt Thoracic Trauma • CXR-widened mediastinum
Blunt Thoracic Trauma • Aortic injury • 80-90% of patients with thoracic aortic rupture die in the pre-hospital setting • Those who survive may have minimal initial symptoms • CXR may be first clue
Penetrating Thoracic Trauma • Emergency Department Thoracotomy • “The surgeon who should attempt to suture a wound of the heart would lose the respect of his surgical colleagues” - Theodore Bilroth, 1882
Penetrating Thoracic Trauma • Emergency Department Thoracotomy
Penetrating Thoracic Trauma • Emergency Department Thoracotomy • Indications • Penetrating thoracic traumatic arrest with previously witnessed cardiac activity • Penetrating thoracic unresponsive hypotension
Penetrating Thoracic Trauma • Emergency Department Thoracotomy
Penetrating Thoracic Trauma • Emergency Department Thoracotomy • Contraindications • Blunt thoracic injuries with no witnessed cardiac activity • Multiple blunt trauma • Severe head injury
Penetrating Thoracic Trauma • Emergency Department Thoracotomy • ACLS algorithms do NOT apply to traumatic arrest
Trauma Ultrasonography • The FAST Exam
Trauma Ultrasonography • Focused Assessment with Sonography for Trauma (FAST) • Limited ultrasound exam • Directed solely at identifying the presence of free intraperitoneal or pericardial fluid • Free fluid is usually due to hemorrhage • Helps determine the need for OR, CT, or angiography
Trauma Ultrasonography • FAST examines four areas for free fluid
Trauma Ultrasonography Low Frequency Probe 2.5 - 5.0 MHz Tissue Penetration
Trauma Ultrasonography • Perihepatic and hepato-renal
Trauma Ultrasonograpy • Spleno-renal
Trauma Ultrasonography • Pelvis
Trauma Ultrasonography • Pericardium
Trauma Ultrasonography • Blunt Abdominal Trauma • Not for bowel injury, solid organ injury, or retroperitoneal injury • Detection of free intraperitoneal or pericardial fluid
Trauma Ultrasonography • EFast Exam • Extended Fast Exam • Anterior lung apices for pneumothorax • Lung bases for pleural fluid
Trauma Ultrasonography • Conclusions • Clinician based ultrasound has changed the way trauma care is practiced and is rapidly becoming standard of care • Noninvasive, straightforward, relatively short training period • Multiple training courses exist • Focused exam, goal specific
