Acute brain herniation is an acute and critical condition in brain surgery or neurology, the specific resuscitation measures are as follows: 1. Resuscitate the vital signs, observe the heart rate, pulse, respiration, blood pressure, etc. The most critical issue is respiration. Patients with brain herniation first appear with bilateral pupil dilatation, coma, and in severe cases, deep, slow and gradual disappearance of spontaneous breathing, requiring immediate tracheal intubation and ventilator In severe cases, the pupils on both sides are dilated and comatose. Debulking decompression is performed to reduce intracranial pressure and treat brain herniation. For patients with acute hydrocephalus, ventricular puncture for cerebrospinal fluid drainage can be performed at the bedside in an emergency to relieve the symptoms of cerebral herniation within a short period of time, within half an hour, to achieve the purpose of saving lives and gaining time for the next treatment.
