World Federation of Neurosurgeons (WFNS) Scale
The WFNS Scale grades subarachnoid haemorrhage using GCS (3-15) and motor deficit presence. Grade I (GCS 15, no deficit) to Grade V (GCS 3-6). It offers superior objectivity and prognostic accuracy over Hunt & Hess. Anaesthesia trainees use it to guide airway planning, monitoring intensity, and postoperative ICU destination in neurocritical care.
