Conclusion For the patients with closed abdominal trauma and craniocerebral trauma, shock and acute intracranial hypertension should be dealt with in time. 結論腹部閉合性損傷合併顱腦損傷的處理，早期應明確傷情，處理好休克與顱內高壓治療的矛盾。
Cerebral perfusion decreases as the intracranial pressure is raised.Irreversible ischemic change occurs when cerebral perfusion pressure is below 40 mmHg. 顱內高壓發生時相對的腦灌流壓下降，腦部的循環便受到影響，當顱內高壓無法控制而腦灌流持續低於四十毫米汞柱時腦部終至缺血而死。
