Initial Management of Motor Vehicle Accident (MVA) Patients in the Emergency Department
The initial management of patients involved in motor vehicle accidents (MVA) should follow a standardized, multidisciplinary approach with immediate triage as high-priority cases, following a predetermined institution-specific protocol that includes systematic assessment and treatment based on the Advanced Trauma Life Support (ATLS) principles. 1, 2
Primary Survey and Immediate Actions
- All MVA patients should be considered high-priority triage cases and evaluated using a structured, institution-specific trauma protocol 1
- Place the patient on a cardiac monitor immediately with emergency resuscitation equipment, including a defibrillator, nearby 1
- Follow the ATLS systematic approach for rapid initial assessment and primary management, starting from the time of injury and continuing through initial assessment, life-saving interventions, re-evaluation, and stabilization 2, 3
Airway and Breathing
- Assess airway patency and provide immediate intervention if compromised 1
- Evaluate breathing and provide supplemental oxygen as needed 2
- Consider early intubation for patients with compromised airway or inadequate ventilation 3
Circulation
- Control obvious external bleeding with direct pressure 1
- Establish IV access with two large-bore catheters 3
- Begin fluid resuscitation for patients showing signs of hemodynamic instability 4
- Monitor vital signs continuously 1
Disability
- Perform a rapid neurological assessment including Glasgow Coma Scale (GCS) 1
- Immobilize the cervical spine until injury is ruled out 1
Exposure
- Completely undress the patient to facilitate thorough examination while maintaining thermal control 2
Diagnostic Evaluation
Immediate Imaging
- Perform an ECG within 10 minutes of ED arrival for patients with chest pain or suspected cardiac injury 1
- For patients with suspected traumatic brain injury (GCS 14-15), obtain a non-contrast head CT scan 1
- Consider focused assessment with sonography for trauma (FAST) for initial triage; positive FAST with hemodynamic instability may lead to immediate surgical intervention 1
Laboratory Studies
- Complete blood count, electrolytes, blood urea nitrogen, creatinine, and glucose 1
- Prothrombin time (with INR) and activated partial thromboplastin time 1
- Cardiac-specific troponin for patients with chest pain or suspected cardiac injury 1
- Toxicology screen to detect cocaine and other substances 1
- Type and cross-match for potential blood transfusion 1
Special Considerations
Cardiac Injury
- For patients with chest pain, ECG abnormalities, or hemodynamic instability after MVA, suspect cardiac injury 1
- Patients with suspected cardiac injuries should undergo rapid cardiac assessment by echocardiography 1
- Cardiac chamber rupture, though rare, has high mortality and requires immediate intervention 1
Traumatic Brain Injury
- For patients with GCS 14-15 and history of head trauma, consider non-contrast head CT 1
- Up to 15% of patients with mild TBI (GCS 15) may have an acute lesion on head CT 1
- Patients with intraparenchymal lesions may have neuropsychological deficits similar to moderate TBI patients 1
Vehicle Telemetry Data
- If available, vehicle telemetry data can provide valuable information about crash dynamics 1
- Factors such as Delta V (change in velocity), direction of impact, and seat belt use are important predictors of injury severity 1
Disposition and Transfer Considerations
- Develop protocols for determining where to take MVA patients, with active involvement of local cardiologists and emergency physicians 1
- Patients with suspected polytrauma should be transported to trauma centers with appropriate capabilities 1
- Patients with known STEMI and/or cardiogenic shock should be sent directly to hospitals with interventional and surgical capability 1
Implementation of Structured Protocols
- Use structured protocols, checklists, or critical pathways for standardized evaluation of MVA patients 1
- The multifaceted, multidisciplinary, standardized approach provides clinical and cost-effective benefits 1, 3
- ATLS training has been shown to improve trauma patient outcomes, particularly in the first hour after admission 3
- Implementation of ATLS principles has demonstrated improvement from sub-standard to standard levels according to Major Trauma Outcome Study methodology 3
Common Pitfalls to Avoid
- Delaying critical interventions while waiting for diagnostic studies 1
- Failing to maintain cervical spine immobilization during the initial assessment 2
- Overlooking less obvious injuries due to focus on the most apparent trauma 1, 5
- Underestimating the severity of injury in patients with normal vital signs who may have occult bleeding 4
- Neglecting to consider cardiac injury in patients with chest trauma from MVAs 1
