简要总结
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.

结局指标
主要结局
Optic nerve sheath diameter 5 minutes after collar placement
时间窗: 1 day after
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.
