Hunt & Hess Classification of Subarachnoid Hemorrhage (SAH)

Hunt & Hess Classification of Subarachnoid Hemorrhage (SAH)

Classifies severity of SAH to predict mortality based on signs and symptoms.

GRADE

Signs & Symptoms

I

Mild headache, alert and oriented, minimal (if any) nuchal rigidity

II

Full nuchal rigidity, moderate-severe headache, alert and oriented, no neurological deficit (besides cranial nerve palsy)

III

Lethargy or confusion, mild focal neurological deficits

IV

Stuporous, more severe focal deficit

V

Comatose, showing signs of severe neurological impairment (example: posturing)

 

Patients with a Grade I bleed have an approximate 30% mortality.

Patients with a Grade II bleed have an approximate 40% mortality.

Patients with a Grade III bleed have an approximate 50% mortality.

Patients with a Grade IV bleed have an approximate 80% mortality.

Patients with a Grade V bleed have an approximate 90% mortality.

MDM - Subarachnoid Hemorrhage (SAH)

[##]-year-old [male/female] presents with [headache/altered mental status] with history and exam consistent with likely subarachnoid hemorrhage (SAH).

Initial considerations in this patient included SAH from ruptured aneurysm, non-aneurysmal bleeding, and trauma, epidural and subdural hemorrhage, intracranial mass, cerebrovascular accident (CVA), transient ischemic attack (TIA), meningitis, encephalitis, and cerebral venous thrombosis among others.

Patient presented [within 6/12/24 hours] of onset of headache concerning for SAH.  Patient noted to have associated [neuro deficits/nuchal rigidity].  CT scan obtained [with/without] clear evidence of SAH.  A lumbar puncture [was not performed due to clear evidence of SAH on CT/was performed with evidence of xanthochrmia consistent with SAH/was not performed due to patient refusal/was unsuccessful prompting us to obtain CT angiogram].  Patient was noted to have a Hunt & Hess Grade [I-V] score as noted above on presentation to the ED.  Patient noted to have [no] history of [anticoagulant or antiplatelet/anticoagulant/antiplatelet] use with [no indication for reversal/reversal of Coumadin initiated with prothrombin complex concentrate (Kcentra)/fresh frozen plasma (FFP) and vitamin K/reversal of Aspirin initiated with DDAVP/reversal of Plavix initiated with platelets/reversal of Dabigatran (Pradaxa) initiated with Idarucizumab (Praxbind)].

Patient was intubated [due to respiratory failure/evidence of inability to protect there airway] as noted above. 

Patient noted to be hypertensive on presentation with [some/minimal] improvement noted with administration of analgesics.  Despite absence of clear consensus recommendations on blood pressure control in the setting of SAH, we initiated treatment with [Nicardipine/Labetalol/Esmolol] with a goal systolic blood pressure of less than 160 mmHg [after consultation with neurosurgery].

Patient noted to be hypotensive on presentation with [IV fluids given/IV fluids and vasopressors initiated] to maintain a goal mean arterial pressure of greater than 80 mmHg.

Patient given Nimodipine via [oral route/NG/OG tube] to decrease incidence of delayed cerebral ischemia.  Seizure prophylaxis initiated in the ED with [Keppra/etc.].  Case discussed with Dr. [NAME] the neuro-interventionalist with plan to [admit/transfer] for endovascular [intervention/clipping/coiling].  We discussed concern for SAH and plan for admission with the [patient/family] with associated risks and benefits, and they demonstrated understanding and agreement with this plan and provided appropriate consent.
