Outline:
6. A subarachnoid hemorrhage is an uncommon type of
stroke caused by bleeding on the surface of the brain.
It is a very serious condition and can be fatal
SAH : fourth most frequent cerebrovascular disorder-
following athero-thrombosis, embolism and primary
intra-cerebral hemorrhage.
CAUSE: Excluding head trauma, the most common
cause of SAH is rupture of vascular aneurysm.
introduction:
7.
8. Subarachnoid Hemorrhage:
Bleeding in the area between the brain and
the thin tissues that cover the brain.
This area is called the subarachnoid space
Definition:
9. •The doctors have confirmed that the main caused
by the presence stretch in one of the main arteries
feeding the brain, and that in 90% of cases as there
are up to 5% of normal people are predisposed to
occurrence of this expansion, and there are 10
people out of every 100 thousand people each
year enter the stage It is called infiltration bloody
phase, which precedes the bleeding or explosion,
and the best treatment of these cases before
entering into this phase where increasing the
chances of successful surgical treatment to 99% if
caught early.
10-12% die before receiving medical attention.
Incidence and Prevalence
10. Many risk factors have been implicated in the pathogenesis of
aneurysmal SAH. They include:
arterial hypertension
atherosclerosis
alcohol use
smoking
race
gender
age
analgesic use
body mass index
drug abuse
oral contraceptive
use
size of unruptured aneurysm
collagen vascular disease
11. and other genetic factors:
a. the incidence of aneurysmal SAH increases with age
reaching a peak in the sixth decade of life.
b. sex: in adults, woman are affected more than men by a
ratio of 3 : 2
c. aneurysmal SAH is rare in children and boys are affected
more than girls by a ratio of 3 : 1
d. race: African-Americans are at a higher risk than white
Americans
e. the critical size of aneurysms determining the risk of
rupture is reported to be between 5 and 7 mm .
f. 11% of patients with either a ruptured or unruptured
aneurysm had a family history of cerebrovascular
disease(compared with 4% of matched controls)
12. Subarachnoid hemorrhage can be caused by:
•Bleeding from (AVM)
•Bleeding disorder
•Bleeding from a
•Head injury
•Unknown cause (idiopathic)
•Use of blood thinners
Subarachnoid hemorrhage caused by injury is often
seen in the elderly who have fallen and hit their head.
Among the young, the most common injury leading to
subarachnoid hemorrhage is motor vehicle crashes.
Causes:
13. in other blood vessels
An aneurysm is an abnormal widening or ballooning of a
portion of an artery due to weakness in the wall of the
blood vessel
•Fibromuscular dysplasia (FMD) and other connective
tissue disorders
•High blood pressure
•History of
Polycystic kidney disease is a kidney disorder passed
down through families in which many cysts form in the
kidneys, causing them to become enlarged.
•Smoking
•A strong family history of aneurysms may also increase
your risk.
Risks Include:
15. subarachnoid hemorrhage (SAH) is classified
according to 5 grades, as follows
• Grade I: Mild headache with or without meningeal irritation
• Grade II: Severe headache and a nonfocal examination, with or
without mydriasis
• Grade III: Mild alteration in neurologic examination, including mental
status
• Grade IV: Obviously depressed level of consciousness or focal deficit
• Grade V: Patient either posturing or comatose
16. The main symptom is a severe headache that starts
suddenly (often called thunderclap headache). It is
often worse near the back of the head. Many
persons often describe it as the "worst headache ever"
and unlike any other type of headache pain. The
headache may start after a popping or snapping
feeling in the head.
Other symptoms:
and alertness
Eye discomfort in bright
Mood and personality changes, including
and irritability
(especially
Nausea and vomiting
Symptoms:
20. The goals of treatment are to:
•Save life
•Repair the cause of bleeding
•Relieve symptoms
•Prevent complications such as permanent
brain damage (stroke)
treatment
21. •How well a patient with subarachnoid hemorrhage
does depends on a number of different factors,
including:
•Location and amount of bleeding
•Complications
•Older age and more severe symptoms can lead to
a poorer outcome.
•People can recover completely after treatment.
But some people die even with treatment.

47. •Grade I or II SAH:
•In patients with a suspected grade I or II
subarachnoid hemorrhage (SAH), emergency
department (ED) care essentially is limited to
diagnosis and supportive therapy.
•Early identification of sentinel headaches is
key to reduced mortality and morbidity rates.
Use sedation judiciously.
•Secure intravenous access, and closely
monitor the patient's neurologic status
48. • Grade III, IV, or V SAH:
• In patients with a grade III, IV, or V subarachnoid hemorrhage (SAH) (ie,
altered neurologic examination), ED care is more extensive.
• Address the patient's airway, breathing, and circulatory status (ABCs). In
addition, reliable neurologic examinations before and after initial
treatment are critically important to optimizing management and to
deciding on the appropriate neurosurgical intervention.
• Intubation
• Endotracheal (ET) intubation of obtunded patients protects them from
aspiration caused by depressed airway protective reflexes. Also intubate
to hyperventilate patients with signs of herniation.
• Precautions
• Avoid excessive or inadequate hyperventilation. Target the partial
pressure of carbon dioxide (pCO2) at 30-35 mm Hg to reduce elevated
ICP. Excessive hyperventilation may be harmful to areas of vasospasm.
• Avoid excessive sedation. It makes serial neurologic exams more difficult
and has been reported to increase ICP directly. However, avoid any
increase in ICP due to excessive agitation from pain and discomfort.
52. •If no aneurysm is found, the person should be
closely watched by a health care team and may
need more imaging tests
•Treatment for coma or decreased alertness
includes:
•Draining tube placed in the brain to relieve
pressure
•Life support
•Methods to protect the airway
•Special positioning
53. •A person who is conscious may need to be
on strict bed rest. The person will be told to
avoid activities that can increase pressure
inside the head, including:
•Bending over
•Straining
•Suddenly changing position
54. •Treatment may also include:
•Medicines given through an IV line to
control blood pressure
•Nimodipine to prevent artery spasms
•Painkillers and anti-anxiety medications to
relieve headache and reduce pressure in the
skull
•Phenytoin or other medications to prevent
or treat seizures
•Stool softeners or laxatives to prevent
straining during bowel movements
55. Adjunctive Therapies and Measures
•Keep the patient's core body temperature at 37.2°C
•Consider antiemetics for nausea or vomiting.
•Elevate the head of the bed 30° to facilitate
intracranial venous drainage. Emergent ventricular
drainage by the neurosurgeon may be necessary.
•Maintain the patient's serum glucose level at 80-120
mg/dL; use sliding or continuous infusion of insulin if
necessary.
•Fluids and hydration
•Do not over hydrate patients because of the risks of
hydrocephalus.
•Patients with subarachnoid hemorrhage (SAH) may
also have hyponatremia from cerebral salt wasting.

-Assess the degree of making a false step in person from the patient, such
as isolating themselves,Note the influence of pain such as: loss of interest
in life, decreased activity, weight loss
Position patient in semi fowler position.
Rational:Pain that has been chronic and long-standing may have
devastating emotional effects on the patient and these emotional
complications may make effective treatment of the pain more difficult.
-Encourage patient to rest in bed.
Rational:to reduce the intensity of pain.
-Provide quite and calm environment.
-Teach relaxation and deep breathing techniques
Rational:to reduce tension and create a feeling more comfortable.
-Give the hot moist compress / dry on the head, neck, arms as needed.
Rational:Hot moist compresses have a penetrating effect. The warmth
rushes blood to the affected area to promote healing
Massage the head / neck / arm if the patient can tolerate the touch.
Rational:to decreases muscle tension and can promote comfort
-Use the techniques of therapeutic touch, visualization, and stress
reduction and relaxation techniques to another.
Rational:Techniques used to bring about a state of physical and mental
awareness and tranquility. The goal of these techniques is to reduce
tensions, subsequently reducing pain.
-Instruct the patient to use a positive statement "I am cured, I'm relaxing, I
love this life“, Instruct the patient to be aware of the external-internal
dialogue and say "stop" or "delay" if it comes up negative thoughts.
Collaboration for providing analgesic as doctor order..

69. intervention
-Closely assess and monitor neurological status frequently and compare with baseline.
Rationale: Assesses trends in level of consciousness (LOC) and potential for increased ICP and is useful in
determining location, extent, and progression of damage. May also reveal presence of TIA, which may warn of
impending thrombotic CVA.
-Evaluate pupils, noting size, shape, equality, light reactivity.
Rationale: Pupil reactions are regulated by the oculomotor (III) cranial nerve and are useful in determining
whether the brain stem is intact. Pupil size and equality is determined
-Document changes in vision: reports of blurred vision, alterations in visual field, depth perception.
Rationale: Specific visual alterations reflect area of brain involved, indicate safety concerns, and influence choice
of interventions.
Assess higher functions, including speech, if patient is alert.
Rationale: Changes in cognition and speech content are an indicator of location and degree of cerebral
involvement and may indicate deterioration or increased ICP.
-Position with head slightly elevated and in neutral position.
Rationale: Reduces arterial pressure by promoting venous drainage and may improve cerebral perfusion.
Maintain bedrest, provide quiet and relaxing environment, restrict visitors and activities. Cluster nursing
interventions and provide rest periods between care activities. Limit duration of procedures.
Rationale Continuous stimulation or activity can increase intracranial pressure (ICP). Absolute rest and quiet may
be needed to prevent rebleeding in the case of hemorrhage
Assess for nuchal rigidity, twitching, increased restlessness, irritability, onset of seizure activity
Rationale: Indicative of meningeal irritation, especially in hemorrhage disorders. Seizures may reflect increased
ICP or cerebral injury, requiring further evaluation and intervention.
Administer supplemental oxygen as indicated.
Rationale: Reduces hypoxemia. Hypoxemia can cause cerebral vasodilation and increase pressure or edema
formation.
