SAH Hunt & Hess Scale Calculator


SAH Hunt & Hess Scale Calculator
Patient’s Condition?

Ever wanted to calculate the SAH Hunt & Hess Scale but found it as confusing as trying to fold a fitted sheet? Well, fear not! We’ve got you covered. But, remember, while humor can make learning fun, calculating the SAH Hunt & Hess Scale is serious business.

Calculation Formula

# This is a hypothetical example, as the SAH Hunt & Hess Scale is primarily based on clinical assessment
SAH_Hunt_Hess_Scale = (Clinical_Variable_1 * Weighting_Factor_1) + (Clinical_Variable_2 * Weighting_Factor_2)

Score Interpretation

Score Severity Clinical Presentation
0 Asymptomatic No SAH
1 Mild SAH Asymptomatic, or minimal headache and slight nuchal rigidity
2 Moderate SAH Moderate to severe headache, nuchal rigidity, no neurologic deficit
3 Severe SAH Drowsy, minimal neurologic deficit
4 Very Severe SAH Stuporous, moderate to severe hemiparesis
5 Critical Condition Coma, decerebrate posturing

Calculation Examples

Name Condition Score Calculation Result
John Doe Mild SAH 1 * 1 1
Jane Doe Severe SAH 3 * 1 3
Sherlock Holmes Critical Condition 5 * 1 5

Calculation Methods over Time

Year Method Advantages Disadvantages Accuracy
1968 Original Hunt & Hess Scale Simple, easy to use Subjective, lacks nuance Moderate
2001 Modified Hunt & Hess Scale More detailed, takes into account more factors More complex High


  1. Clinical Subjectivity: The SAH Hunt & Hess Scale relies heavily on clinical assessment, which can vary between assessors.
  2. Lack of Nuance: The scale may not capture the full complexity of a patient’s condition.

Alternative Methods

Method Pros Cons
World Federation of Neurological Surgeons (WFNS) Scale More detailed, less subjective More complex, takes longer to calculate


  1. What is the SAH Hunt & Hess Scale? The SAH Hunt & Hess Scale is a grading system used to classify the severity of a subarachnoid hemorrhage (SAH), primarily based on clinical assessment.
  2. How is the SAH Hunt & Hess Scale calculated? The SAH Hunt & Hess Scale is a clinical score, calculated based on the patient’s symptoms and presentation.
  3. Who can use the SAH Hunt & Hess Scale? The SAH Hunt & Hess Scale is primarily used by healthcare professionals for clinical assessment of subarachnoid hemorrhage.
  4. Is the SAH Hunt & Hess Scale accurate? Like all clinical assessment tools, the SAH Hunt & Hess Scale has its limitations and should be used in conjunction with other diagnostic methods.
  5. Can the SAH Hunt & Hess Scale predict outcomes for SAH patients? While the SAH Hunt & Hess Scale provides a severity grading, it does not directly predict outcomes. However, a higher score often correlates with worse prognosis.
  6. What is a subarachnoid hemorrhage? A subarachnoid hemorrhage is a type of stroke caused by bleeding in the space surrounding the brain.
  7. What are the symptoms of a subarachnoid hemorrhage? Symptoms can include a sudden, severe headache, nausea and vomiting, stiff neck, blurred or double vision, sensitivity to light, and loss of consciousness.
  8. How is a subarachnoid hemorrhage diagnosed? It is usually diagnosed using a combination of clinical assessment, imaging tests like a CT scan or MRI, and sometimes a lumbar puncture.
  9. What is the treatment for a subarachnoid hemorrhage? Treatment typically involves stabilizing the patient, stopping the bleeding, and preventing complications. This can involve medication, surgery, or other procedures.
  10. Can a subarachnoid hemorrhage be prevented? While not all subarachnoid hemorrhages can be prevented, controlling high blood pressure and avoiding smoking can reduce your risk.
