Cervical Collar Use in Trauma Patients

Introduction to Cervical Collar Recommendations

The American Heart Association recommends against the routine application of cervical collars by first aid providers due to growing evidence of harm and lack of proven benefit in patients with trauma, as they cause documented harm without proven benefit in preventing secondary spinal cord injury 1, 2

Cervical collars can cause increased intracranial pressure, particularly dangerous in patients with co-existing head trauma, and this is a significant concern in trauma patients 1, 2
The use of cervical collars is associated with pressure ulcers requiring skin grafting and potentially causing sepsis, with each ulcer costing approximately $30,000 to treat, highlighting the need for careful consideration of their use 1, 2
Cervical collars can lead to difficult airway management due to reduced mouth opening, increasing the risk of failed intubation in patients requiring airway management 3, 1
Prolonged immobilization with cervical collars can result in ventilator-associated pneumonia and delirium, emphasizing the importance of minimizing their use 1
Bacteremia and sepsis can occur from poor oral care associated with collar use, underscoring the need for meticulous patient care 1

There is no high-quality evidence demonstrating clinical benefit of cervical collar use for injured patients, leading to recommendations against their routine use 1
Cervical collars provide incomplete immobilization, particularly at craniocervical and cervicothoracic junctions, which may not effectively prevent secondary spinal cord injury 1
In cadaveric models with unstable cervical spine injuries, collars paradoxically caused greater cervical spine movement compared to manual in-line stabilization during intubation, highlighting their potential to cause harm 3, 1

Instead of routine collar application, patients should remain as still as possible while awaiting EMS arrival to minimize the risk of secondary spinal cord injury 1
Manual stabilization may be considered in high-risk circumstances where patient movement cannot be controlled, or during airway management procedures as an alternative to rigid collars 1, 4, 3

During airway management, removing at least the anterior portion of any cervical collar during intubation attempts can improve glottic exposure and reduce difficult intubation rates, as recommended by the 2024 Difficult Airway Society guidelines 3, 5, 1
Videolaryngoscopy is preferred over direct laryngoscopy, and manual in-line stabilization should be applied during intubation attempts to minimize the risk of secondary spinal cord injury 1, 3
For obtunded patients requiring clearance, obtaining high-quality cervical spine CT rather than prolonged collar immobilization is recommended, and collars should be removed by hospital day 3 if CT is negative 1
Modern CT imaging is highly sensitive for detecting unstable injuries in patients with decreased level of consciousness, supporting its use in this population 1

Prolonged collar use beyond 48-72 hours when not indicated by clinical or radiographic findings can lead to increased morbidity, and delaying collar removal in patients cleared by appropriate imaging can also cause harm 1, 2
Keeping collars on during intubation attempts without removing at least the anterior portion can increase the risk of difficult intubation, and assuming collars provide effective immobilization can lead to inadequate care 3, 1

In pre-hospital and military settings, airway management should follow standard algorithms, prioritizing airway security over spinal immobilization concerns, due to limited data in these environments 3
In patients with head trauma, particular caution should be exercised with collar use due to increased intracranial pressure risk, emphasizing the need for careful consideration of their use in this population 1, 2
