Emergent Head Pain Flashcards
what are the 3 questions you ask a patient with a headache?
- onset = how rapidly did it come on?
- severity = how bad is the pain?
- frequency = have you had a similar headache before?
what are the 2 emergent periorbital conditions?
orbital cellulitis and giant cell arteritis (GCA)
what are the 6 emergent cranial conditions?
aneurysm, subarachnoid hemorrhage, meningitis/encephalitis, malignant hypertension, cavernous sinus thrombosis, tolosa-hunt syndrome and carotid cavernous sinus fistula
why is orbital cellulitis life-threatening?
it can spread to the interior of the skull and kill the patient in a matter of days via the superior orbital fissure
needs IV antibiotics
what are the symptoms of orbital cellulitis?
eye/adnexa are significantly edematous and hyperemic, mucopurulent discharge, painful to touch and on eye movements
patient is in distress
what are the signs and symptoms of GCA?
age >60, elevated sedimentation rate (>50), patient is unwell, fever, jaw claudication, scalp tenderness, weight loss, palpable temporal artery
associated with polymyalgia rheumatica
why is GCA an emergency?
once the optic nerve has stroked, it dies within 4 minutes
then the fellow eye has an elevated risk
there is no recovery
what is an aneurysm?
a ballooning out of the wall of an artery (typically) or a vein
usually at the circle of willis
causes a headache (severity 9-10) and widespread, sudden onset
what are the signs/symptoms for an aneurysm?
CN3 (pupil and EOMs) or CN6 may be involved, may have VA or VF loss, patient is unwell, distressed, NO fever
frequently has neurologic signs and a change in mental status
what can cause a subarachnoid hemorrhage?
an aneurysm or head trauma
what is the typical/classic case for subarachnoid hemorrhage?
rapid onset, worst headache of their life, pain with head movement/stiff neck, NO fever and positive for other signs of an aneurysm
what are the signs of an atypical SAH?
history of recent head trauma, accompanied by nausea, vomiting, syncope, seizures
how does meningitis/encephalitis present?
patient is unwell/distressed with a FEVER, stiff neck, neck pain, and pain on head movement
frequently has change in mental status and neurologic changes
what is malignant hypertension and what causes it?
rapid rise in BP (160/100)
pain is due to distension of cerebral arteries or traction on bridging vessels
they also have blurred VA, papilledema and change in mental status
how do you test CN 2, 3, 4, 6 function?
VA, VF, pupils, ptosis, EOMs
