Effect of Cervical Collar on Intracranial Pressure

Lazarski University60 enrolled

Overview

The routine use of cervical collar in emergency medical conditions has recently been questioned. The application of cervical collars, as their opponents point out, results in deterioration of intubation conditions, intensification of pain in the region of mastoid processes, and impaired venous outflow from the head.

Outcomes

Primary Outcomes

Optic nerve sheath diameter 5 minutes after collar placement

During each evaluation with Optic nerve sheath diameter, at least three measurements were attempted from each eye. The ONSD was measured 3 mm behind the retina. All scans were performed using a 13-6 MHz linear-array probe and a high resolution optimization setting.

Time frame: 1 day after
