Open neck injury
The neck contains the cervical spine, pharynx, larynx, trachea, esophagus, and important blood vessels and nerves. It is supported and protected by the mandible, sternum, clavicle, shoulder, and cervical spine, but open injuries are still not uncommon. Open injury of the neck can often cause partial or complete rupture of the larynx, trachea, pharynx, esophagus, and cervical spine, and cause cervical emphysema, pneumothorax, hemothorax, and even pericardial tamponade and massive hemorrhage shock. The condition is very dangerous, with a mortality rate of 2% to 10%. Therefore, immediate on-site emergency treatment is necessary. Pay attention to protecting the cervical spine during transportation to prevent further injury during operation.
