WFNS scale

Grades subarachnoid hemorrhage by Glasgow Coma Scale and focal motor deficit, with less subjectivity than Hunt–Hess.

Method · Limits of application

WFNS/Teasdale 1988: GCS and motor deficit, 5 grades

The 1988 WFNS combines Glasgow and motor deficit to grade subarachnoid hemorrhage; grade zero in the source corresponds to an unruptured aneurysm and is distinct from the five hemorrhage grades. Use a Glasgow score that can be assessed clinically and document factors that interfere with the examination. The article does not describe the combination of Glasgow 15 with motor deficit; the interface retains grade I and displays this caveat, without presenting it as a validated combination. This is the original edition, not a later modified WFNS, and it does not provide an automatic individual prognosis.

Conditions of use

Check the population, units, inclusion and exclusion criteria, and version in the original source. A result alone does not establish a diagnosis, discharge decision or prescription.

Documented formula

Transcribed from the source or a recorded revision; this is not a clinical recommendation.

I: Glasgow 15, no motor deficit · II: 13 to 14, no deficit · III: 13 to 14, deficit · IV: 7 to 12, with/without deficit · V: 3 to 6, with/without deficit.
