6. Stroke is the leading cause of adult disabilities
2nd leading cause of death worldwide
3rd leading cause of death in the U.S.
800,000 strokes per year resulting in 150,000 deaths
Deaths are projected to increase exponentially in the next
30 years owing to the aging population
The annual cost of stroke in the U.S. is estimated at
$69 billion
Stroke can be divided into hemorrhagic and ischemic
origins
13% hemorrhagic
87% ischemic
7. Usually occurs spontaneously
Caused by vascular rupture with
bleeding into brain
Mass effect can further cause
bleeding and hematoma expansion
from neighboring vessels
Hematoma growth over several
hours following presentation of
symptoms is common (30-40%)
Hemorrhages commonly occurs
at the basal ganglia, thalamus,
pons, or cerebellum
8. Epidural hematoma: results from damaged artery
risk for bursting (e.g. meningeal artery)
Commonly due to head trauma associated with skull
fracture
Mass effect may occur after several hours
Subdural hematoma: develops from damaged veins
leakage of blood to subdural space (e.g. cortical
veins bridging)
Commonly due to head trauma
Mass effect may occur after several days
Common in elderly population
10. Subarachnoid hemorrhage:
May result from head injury, rupture of arterial
aneurysm, or spread of blood from different
location to subarachnoid space
Most common: berry aneurysm
▪ ↑ICP disrupts blood flow in brain generalized
concussion
12. Intracranial hemorrhage (ICH):
Hematomas focal neurologic deficits due to
pressure pushing against nearby brain structures
Blood leakage cause damages to surrounding
brain tissues
Patients with high blood pressure most
common cause for non-traumatic ICH
14. Chronic hypertension structural wall changes of small arteries and
arterioles in the brain
Fibrinoid necrosis
Charcot-Bouchard aneurysms
Idiopathic hypertension (acute) usually younger patients with history
of drug abuse
Amphetamine, cocaine
May occur minutes to hours after drug use
Vascular malformations
Arteriovenous malformations (AVM): failure of formation of capillary beds
Saccular (berry): results from developmental weakness of arteriole walls
Hemorrhages can cause compression to nearby brain tissues
May result in brain tissue inflammation and edema

▪ FFP or PCCs
Patients with a severe coagulation factor deficiency
or severe thrombocytopenia
Factor replacement therapy or platelets
▪ Recombinant Factor VIIa (rFVIIa)
New recommendation; 2010 Guidelines
27. Replenishment of Clotting Factors:
FFP PCCs
Historically recommended Rapid reconstitution and
administration
• Increased risk of allergic & • Processed clotting factors
infectious rxns • Inactivated infectious agents
Large Volumes Small volumes
- Fluid overload
Note: No difference in clinical outcome with FFP vs. PCC’s but PCCs lead
to less complications
28. Use of platelet transfusions in ICH patients with
a history of antiplatelet use is unclear

better outcomes
31. Antihypertensive agents for ICH have not been
compared in controlled trials
Suggested agents:
Labetolol
Enalapril

SBP > 200 mmHg or MAP is 150 mmHg Aggressive BP with continuous IV infusion,
with frequent BP monitoring Q5 min
SBP is 180 mmHg or MAP is 130 mmHg Monitor ICP and BP using intermittent or
continuous IV meds while maintaining cerebral
and
perfusion pressure 60 mmHg
there is the possibility of ICP
SBP is 180 mmHg or MAP is 130 mmHg Modest BP (eg, MAP of 110 mm Hg or target
BP of 160/90 mm Hg) using intermittent or
and
continuous IV meds to control BP and clinically
there is no evidence of ICP reexamine the patient Q15 min
33. Elevate head of bed to 30 degrees
Analgesia and sedation as needed
Aggressive therapies:
Osmotic therapy

Retrieved October 26, 2012 from http://0-www.accessmedicine.com.library.touro.edu/content.aspx?aID=56675112.Acute HTN: The role of acute—as opposed to chronic—hypertension in the pathogenesis of intracerebral hemorrhage is uncertain. Most patients with intracerebral hemorrhage are hypertensive after the event, but this may be explained by baseline hypertension, the vasopressor response to increased intracranial pressure (Cushing reflex), or both. In addition, large intracerebral hemorrhages are an uncommon feature of acute hypertensive encephalopathy. Nevertheless, the fact that some patients with spontaneous intracerebral hemorrhage have no history of hypertension and lack signs of hypertensive end-organ disease suggests that more acute hypertensive episodes might be involved, as does the occurrence of intracerebral hemorrhage in young patients after amphetamine or cocaine abuse.

Teasdale G, Jennett B. Assessment of coma and impaired consciousness. A practical scale. Lancet 1974; 2:81.
Patients undergoing treatment with OACs constitute 12% to 14% of patients with ICH,34,35 and with increased use ofwarfarin, the proportion appears to be increasing.36 Recognition of an underlying coagulopathy thus provides an opportunity to target correction in the treatment strategy
Notept very disoriented during admission
Endotracheal intubation in patients with decreased level of consciousness and poor airway protection
No difference in clinical outcome between FFP’s and PCC’s but PCC use associated with fewere complications.Although rFVIIa can reverse INR in OAC-ICH, it doesn’t replenish all the vit K dependent factors and therefore may not restore thrombin generation as well as PCCsStudies may suggest use of rFVIIa can limit hematoma enlargement – however benefit in ICH patients remains unproven. Risk for clot increased – use is not recommended
Up to 28% of patients with ICH experience seizures – often nonconvulsive in nature
BP generally falls spontaneously within several days after ICH, but high BP persists in many patientsHTN can lead to expansion of hematoma, edema, and rebleeding; it’s vital to decrease BP. SBP >140-150 associated with double the risk of mortality CCB’s acutely lower DBP and associated with worse outcomesINTERACT STUDY – Target SPB goal of 140 vs 180 w/in 1 hour
Class C recommendations (weak)
Hyperventilation not recommended b/c its effects are transient, it decreases CBF and it may lead to rebound increases in ICPGlucocorticoids are not effective and result in higher rates of complications and poorer outcomes
Hyperactive, hypoactive, mixed--decrease in mortality from ARDS probably due to several factors, including improved supportive care and a more thoughtful approach to mechanical ventilation. --Key components of supportive care include intelligent use of sedatives and neuromuscular blockade, careful hemodynamic management, nutritional support, control of blood glucose, expeditious evaluation and treatment of nosocomial PNA, and prophylaxis against (DVT) and (GI) bleeding. FASTHUG-------Data suggest conservative fluid management strategy that aims to minimize or eliminate positive fluid balance — for example, by aiming for a CVP <4 mmHg or a PAOP <8 mmHg — offers clinical advantages, including improved oxygenation--VAP is a frequent complication of ARDS. Empiric abx coverage should be sufficiently broad. Strategies include avoiding: the supine position, excess sedation, unnecessary antibiotics, and unnecessary ventilator circuit changes. Additional strategies include providing good mouth care, weaning patients from the ventilator in a timely manner, and perhaps use of continuous subglottic aspiration. --Patients with hypoxic respiratory failure may benefit from strategies that decrease oxygen utilization, such as antipyretics to control fever and sedatives to control agitation. NMB may be required, particularly when asynchrony with the ventilator persists despite adequate sedation.
