Initial Management of Motor Vehicle Accident Patients

Primary Survey and Immediate Actions

  • The American College of Radiology recommends that all MVA patients be considered high-priority triage cases and evaluated using a structured, institution-specific trauma protocol, following the Advanced Trauma Life Support (ATLS) principles 1, 2
  • The American College of Cardiology suggests placing the patient on a cardiac monitor immediately with emergency resuscitation equipment, including a defibrillator, nearby 2, 3

Airway and Breathing

  • The American College of Radiology recommends assessing airway patency and providing immediate intervention if compromised 1

Circulation

  • The American College of Radiology recommends controlling obvious external bleeding with direct pressure 1
  • The American College of Cardiology suggests monitoring vital signs continuously 2

Disability

  • The American College of Emergency Medicine recommends performing a rapid neurological assessment including Glasgow Coma Scale (GCS) 4, 5
  • The American College of Radiology recommends immobilizing the cervical spine until injury is ruled out 1

Diagnostic Evaluation

Immediate Imaging

  • The American College of Cardiology recommends performing an ECG within 10 minutes of ED arrival for patients with chest pain or suspected cardiac injury 6, 2
  • The American College of Emergency Medicine suggests obtaining a non-contrast head CT scan for patients with suspected traumatic brain injury (GCS 14-15) 4
  • The American College of Radiology recommends considering focused assessment with sonography for trauma (FAST) for initial triage 1

Laboratory Studies

  • The American Heart Association recommends complete blood count, electrolytes, blood urea nitrogen, creatinine, and glucose 7
  • The American Heart Association suggests prothrombin time (with INR) and activated partial thromboplastin time 7
  • The American Heart Association recommends cardiac-specific troponin for patients with chest pain or suspected cardiac injury 7
  • The American College of Radiology recommends type and cross-match for potential blood transfusion 1

Special Considerations

Cardiac Injury

  • The American College of Radiology recommends suspecting cardiac injury for patients with chest pain, ECG abnormalities, or hemodynamic instability after MVA 1
  • The American College of Radiology suggests undergoing rapid cardiac assessment by echocardiography for patients with suspected cardiac injuries 1

Traumatic Brain Injury

  • The American College of Emergency Medicine recommends considering non-contrast head CT for patients with GCS 14-15 and history of head trauma 4, 5
  • The American College of Emergency Medicine suggests that up to 15% of patients with mild TBI (GCS 15) may have an acute lesion on head CT 4

Disposition and Transfer Considerations

  • The American Heart Association recommends developing protocols for determining where to take MVA patients, with active involvement of local cardiologists and emergency physicians 9
  • The American College of Radiology suggests transporting patients with suspected polytrauma to trauma centers with appropriate capabilities 1, 2
  • The American Heart Association recommends sending patients with known STEMI and/or cardiogenic shock directly to hospitals with interventional and surgical capability 9

Implementation of Structured Protocols

  • The American College of Cardiology recommends using structured protocols, checklists, or critical pathways for standardized evaluation of MVA patients 2, 3

Common Pitfalls to Avoid

  • The American College of Radiology recommends avoiding delaying critical interventions while waiting for diagnostic studies 1
  • The American College of Radiology suggests avoiding neglecting to consider cardiac injury in patients with chest trauma from MVAs 1
