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.

MDM - Tension Headache


[##-year-old male/female] with headache with history and exam consistent with likely tension headache.

Initial consideration in this patient included tension headache, migraine, cluster headache, meningitis, encephalitis, subarachnoid hemorrhage (SAH), venous sinus thrombosis, and intracranial hemorrhage or tumor among others.

Patient presented with headache and a normal neurologic exam without report of preceding trauma.  Headache described as [tightness/pressure] in the [right/left/bilateral temporal/frontal/parietal] head without report of associated [nausea/blurred vision/photophobia], or other features suggestive of migraine headache.  Patient reports recent [decreased caffeine intake/insomnia/stress] suggestive of tension-type headache.  Patient reported onset of headache was gradual, with no report of headache that was maximal at onset or thunderclap in nature.  Doubt subarachnoid hemorrhage at this time [in patient meeting none of the Ottawa SAH rules as noted above].  No fever, evidence of meningismus, or systemic infectious symptoms suggestive of meningitis or encephalitis at this time.  No indication for neuroimaging at this time based on normal neurologic exam in patient with headache with features suggestive of tension-type headache.  Patient reported significant improvement with [treatment] prior to discharge from ED.

Prior to discharge, we discussed return precautions, specifically for evidence of worsening headache or neurologic deficits, symptomatic treatment, and follow up with primary care doctor within [2-3 days/1 week] for further evaluation, and the patient demonstrated understanding and agreement.

Decision Rule - Ottawa Subarachnoid Hemorrhage (SAH) Rule

Ottawa Subarachnoid Hemorrhage (SAH) Rule:

-Age ≥40 . . . . . . . . . . . . . . . . . . . . . . . . . . .  [No (0 points)/Yes (+1 point)]
-Neck pain or stiffness   . . . . . . . . . . . . . . .  [No (0 points)/Yes (+1 point)]
-Witnessed loss of consciousness . . . . . . .  [No (0 points)/Yes (+1 point)]
-Onset during exertion  . . . . . . . . . . . . . . .  [No (0 points)/Yes (+1 point)]
-Thunderclap headache   . . . . . . . . . . . . . .  [No (0 points)/Yes (+1 point)]
  (Defined as headache peaking within 1 second)  
-Limited neck flexion on examination . . . .  [No (0 points)/Yes (+1 point)]

TOTAL SCORE = [## points]

A subarachnoid hemorrhage (SAH) cannot be ruled out if one or more criteria above are met.  
Provider may consider avoiding further subarachnoid hemorrhage (SAH)-specific workup in patients who meet all negative criteria.

Procedure Note - Lumbar Puncture (LP)



Lumbar Puncture Note:

The patient was counseled on the risks, benefits, and alternatives to the procedure, and provided consent.  A timeout procedure was performed prior to initiating the procedure.  

The performing physician and support staff donned appropriate sterile garments, including surgical masks, sterile gloves, and caps.  The patient was placed in the [left/right lateral recumbent/seated and flexed] position with help from the supporting staff.  The area was cleansed and draped in usual sterile fashion using [betadine/chlorhexidine] scrub.  Anesthesia was achieved with [##] mL of lidocaine injected subcutaneously.  

A [##] gauge [##] inch spinal needle was placed in the [L2-L3/L3-L4/L4-L5] interspace.  On the [first/second/etc.] attempt, [clear/bloody/straw-colored] cerebral spinal fluid was obtained.  The opening pressure was [##] cm of H2O. 

CSF was collected into 4 tubes.  These were sent for the usual tests with 1 tube to be held for further analysis if needed.  A sterile bandage was placed over the puncture site.

The patient had no immediate complications and tolerated the procedure well.
