The Hunt and Hess scale, is one of the grading systems used to classify the severity of a subarachnoid hemorrhage based on the patient's clinical condition.
- Grade 0 - Unruptured aneurysm
- Grade I - Asymptomatic or mild headache and slight nuchal rigidity
- Grade Ia - Fixed neurologic deficit without acute meningeal/brain reaction
- Grade II - Cranial nerve palsy, moderate to severe headache, nuchal rigidity
- Grade III - Mild focal deficit, lethargy, or confusion
- Grade IV - Stupor, moderate to severe hemiparesis, early decerebrate rigidity
- Grade V - Deep coma, decerebrate rigidity, moribund appearance
The original 5 grading scale was modified as seen above to include grade 0 and Ia. [17] | |
