1.Immediate Assessment
Stabilize ABCs. Baseline exam (GCS, pupils, focal deficits). Anticoagulant history — agent and last dose.[+]
2.Imaging
NCCT head: location, volume (ABC/2), IVH, midline shift. CTA if vascular etiology possible (young, lobar, no HTN).[+]
3.Anticoagulation Reversal
Warfarin: 4-factor PCC 25-50 units/kg IV + Vitamin K 10 mg IV (goal INR <1.4). If PCC unavailable, FFP 10-15 mL/kg. Dabigatran: idarucizumab 5 g IV. Xa inhibitors: 4-factor PCC 50 units/kg IV. Andexanet alfa was withdrawn from the US market (commercial sales ended Dec 22, 2025). Do not wait for labs when the history is clear. (2022 AHA/ASA ICH, Class I, Level B.)[+]
4.Blood Pressure
SBP <140 mmHg within 1 hour when feasible (Class I, Level A). Nicardipine or labetalol. Avoid SBP <110 mmHg; avoid rapid drop (e.g. >90 mmHg in 1 h). Evidence: INTERACT-2, ATACH-2; 2022 AHA/ASA ICH Guidelines.[+]
5.ICP and Herniation
HOB 30°. Hyperosmolar therapy (mannitol, 3% saline). Hyperventilation as bridge only. EVD if hydrocephalus from IVH.[+]
Surgery
Most supratentorial ICH: medical. STICH II-type — consider evacuation. Cerebellar hemorrhage >3 cm with neurological decline or brainstem compression or hydrocephalus: evacuate (Class I, Level B). EVD for hydrocephalus from IVH.[+]
6.ICU and Complications
Seizure: treat if clinical; no routine prophylaxis. DVT: SCDs; chemoprophylaxis after 24–48 h if stable. Glucose 140–180. Treat fever.[+]
Do not give tPA or antiplatelets in acute ICH. Reverse anticoagulation before any elective procedure.
