Open craniocerebral injury generally has a heavy clinical manifestation, sometimes combined with hemorrhagic shock, respiratory and circulatory instability, which can easily lead to intracranial infection. Therefore, the treatment principles for open craniosynostosis mainly include: 1. maintain the stability of respiration and circulation. 2. try not to scratch the wound too much during first aid, dressing as soon as possible to reduce bleeding and secondary injury and contamination. Do not easily pull out or shake the wound when there is an injury-causing object left in it.3. The principle of open brain injury is to perform debridement and suturing as early as possible to convert open brain injury into closed. If the brain tissue is collapsed and the brain is pulsating well after debridement, suturing or repairing the dura can be done. If the brain contusion is severe and the intracranial pressure is still high after debridement, the dura mater can be closed without sutures. For infected open cranial injury, anti-infection and wound drainage should be carried out first, and then late debridement should be carried out after the infection is controlled.4. Foreign body treatment, those who have injury-causing objects embedded in them should not be pulled out hastily, and should be clearly checked for wound alignment before debridement.
