Management of Intracranial Hemorrhage

Initial Assessment and Intervention

Patients with life-threatening brain lesions require urgent neurosurgical consultation and intervention after control of any life-threatening systemic hemorrhage, as recommended by the World Journal of Emergency Surgery 1, 2, 3
Patients with exsanguinating hemorrhage require immediate intervention for bleeding control before addressing intracranial pathology, with a goal to maintain systolic blood pressure >100 mmHg or mean arterial pressure >80 mmHg during hemorrhage control interventions 1, 2, 4, 5, 6
Urgent neurological evaluation, including pupillary assessment and Glasgow Coma Scale motor score, should be performed once systemic bleeding is controlled, along with an immediate brain CT scan to determine severity of brain damage and identify life-threatening lesions 2, 3, 4

Life-threatening brain lesions requiring urgent neurosurgical consultation include cerebellar hemorrhage with neurological deterioration, brainstem compression, and/or hydrocephalus from ventricular obstruction, as well as patients with intracranial mass lesions causing significant mass effect or midline shift 1, 2, 3, 7
Patients showing signs of impending herniation also require urgent neurosurgical consultation 1, 3, 6

Maintain systolic blood pressure >100 mmHg or mean arterial pressure >80 mmHg during emergency neurosurgery, with lower values tolerated only for the shortest possible time during difficult intraoperative bleeding control 1, 5, 6
Maintain platelet count >50,000/mm³ for emergency neurosurgery, including ICP probe insertion, with higher values advisable 1, 3, 6
Maintain PT/aPTT <1.5 times normal control during emergency neurosurgery, and utilize point-of-care testing if available to optimize coagulation function 1, 3, 6
Transfuse RBCs for hemoglobin <7 g/dL during emergency neurosurgery, with higher thresholds used in elderly patients or those with limited cardiovascular reserve 1, 2, 6

Maintain PaO₂ between 60-100 mmHg and PaCO₂ between 35-40 mmHg during emergency neurosurgery 1, 2, 3, 6
Consider temporary hypocapnia for cerebral herniation awaiting or during emergency neurosurgery, with a goal to reduce PaCO₂ temporarily below 35 mmHg 1, 3

Do not delay neurosurgical consultation while attempting medical management alone in patients with life-threatening mass lesions, as recommended by the World Journal of Emergency Surgery 1, 2, 3
Do not allow hypotension or hypoxia, which worsen secondary brain injury, and do not insert ICP monitors without correcting coagulopathy 1, 3, 6, 7, 9
