Increased Intracranial Pressure ICP

  • pressure exerted by the volume of the intracranial contents within the cranial vault

  • Core principles:

    • The cranial vault is comprised of brain tissue, blood, and CSF, which are typically in equilibrium and produce stable ICP.

    • Monroe-Kellie hypothesis – there is only so much space for each component. An increase in one will result in a change in the volume of the others to stabilize ICP.

  • Etiologies:

    • Head injury/ trauma

    • Skull fracture

    • Hematoma

    • Brain tumors

    • meningitis complications

    • Subarachnoid hemorrhage

    • Toxic and viral encephalopathies

  • Decreased cerebral perfusion → cerebral edema → shifting of brain tissue → herniation → death

NEVER DO A LUMBAR PUNCTURE

ICP parameters

  • Normal ICP

    • 0-10mm Hg

    • 15 id high-normal

  • Increased ICP

    • 16-20mm Hg]

  • Danger zone

    • 25mm Ha

Movement can cause a transient increase in ICP, which should be momentary and self-regulate

Cushing’s triad

  • Wide BP, Low Pulse, Irratic respirations

    • ex) BP 168/58, P 58, RR 10

Cushing’s response (also called Cushing’s reflex) is seen when cerebral blood flow decreases significantly.

ICP Clinical manifestations

Early

  • Altered mentation

  • Confusion

  • irritability

  • visual changes

  • Pupillary changes (sluggish), impaired EOM (CN II, III, IV, VI)

  • Focal weakness, hemiparesis

  • Headache

    • Constant

    • Increasing in intensity

    • Aggravated by movement or straining

Late

  • LOC → comatose (GCS 8 or less)

  • FEVER

  • VS changes

    • Decreased or erratic HR, RR

    • Increased SBP, pulse pressure (SBP-DBP)

  • Irregular respiratory patterns

    • Cheyne-Stokes – long, labored, shallow, apnea

  • Projectile vomiting 2/2 medullar depression

  • Pressure on brainstem → hemiplegia, decorticate or decerebrate posturing, bilateral flaccidity

  • Loss of brainstem reflexes – pupillary, corneal, gag, swallowing

4
New cards

ICP diagnostics

  • Neuroimaging – CT, MRI most commonly

  • Transcranial doppler – measures cerebral blood flow

  • NEVER ATTEMPT LUMBAR PUNCTURE IN A PATIENT WITH SUSPECTED OR CONFIRMED INCREASED ICP

5
New cards

ICP complications

  • Neuroendocrine derangements

    • Neurogenic diabetes insipidus → decreased ADH → volume depletion

      • Vasopressin

    • SIADH → increased ADH → volume overload

      • Urine output > 200 mL/hr for 2 consecutive hours

  • Herniation → decreased cerebral blood flow → ischemia → infarction → brain death

6
New cards

ICP Monitoring

  • Invasive

  • Intraventricular catheter/extra-ventricular drain (EVD)

    • Complications include infection, meningitis, ventricular collapse, catheter occlusion, problems with monitoring system

    • Aseptic technique

    • Continuous drainage of CSF under pressure control is an effective method of treating intracranial hypertension.

  • Subarachnoid screw/bolt

    • Complications include infection, screw occlusion by clot or brain tissue

    • output is recorded on an oscilloscope not requiring a ventricular puncture

Subarachnoid screw boltIntraventricular catherter/ extra-ventricular drain EVD

7
New cards

ICP Medical Management

  • Goal is to immediately 1) decrease cerebral edema, 2) decrease the volume of CSF or 3) decrease cerebral blood volume while maintaining cerebral perfusion

    • Osmotic diuretics

      • mannitol

      • 3% NS

    • Corticosteroids if 2/2 tumor

    • Fluid restriction

    • Draining CSF – via EVD, NOT LP

    • Reducing metabolic demands

      • fever management

      • hypothermia?

      • reduce O2 needed

    • Decompressive hemicraniectomy

      • last result

  • Maintain hemodynamic stability, cerebral perfusion

    • Ionotropes (dobutamine, norepinephrine) → increased cardiac output

  • Monitor fluids and electrolytes

    • Foley

    • Serum osmolality, electrolytes

New cards

ICP Nursing process

Assessment

  • Pertinent PMHx – may be obtained from family/friends

  • Initial neurologic exam must be as comprehensive as possible

    • Subsequent exams care more focused – pupil checks, specific CNs, GCS

  • Monitoring of VS and ICP

Diagnoses

  • Impaired breathing

  • Risk for ineffective tissue perfusion

  • Hypovolemia 2/2 fluid restriction

  • Risk for infection associated with ICP monitoring

Beware of activities or interventions that may increase ICP, minimize intraabdominal/thoracic pressure

  • Be mindful of patient positioning, movement, turning

  • Avoid Valsalva – YES to stool softeners, NO to enemas; exhale with movement

  • Space out nursing interventions, promote calm environment

  • ICP should not increase beyond 25 mm Hg, and should normalize within ~ 5 min

  • Otherwise, may need sedation

Planning

  • Maintaining patent airway (A)

    • Suction with caution (up to 15s)

    • Pre-oxygenate with 100% O2 if on mechanical ventilator

    • Coughing discouraged bc increases ICP

Normalizing respiratory pattern (B)

Optimizing cerebral tissue perfusion (C)

  • HOB @ 30-45º; keep head in neutral, midline position

  • Hyperventilation → decreased PaCO2 → cerebral vasoconstriction?

  • Monitor ABGs

Maintain negative fluid balance

  • 3% saline

  • Osmotic and loop diuretics

  • Fluid restriction – assess VS, skin turgor, mucous membranes, urine output (Foley), serum/urine osmolality; oral hygiene, perioral care

  • *Fluid replacement – slow to moderate rate

  • Mannitol, hypertonic saline - fluid shifts from intracellular → intravascular

    • Increased cardiac workload – monitor for pulmonary edema, heart failure

      • monitor urine osmolality, obtain I/O, accurately record ICP readings

    • urine output is monitored hourly.

Preventing infection

  • Aseptic technique when managing EVD system

  • Always examine CSF

    • usually clear

  • Monitor for meningitis

  • Monitor for other signs of local, systemic infection

Monitoring and managing potential complications

  • Assess, document, notify

  • Monitor for sustained increased ICP

11
New cards

Ischemic Stroke

Disruption of blood flow → decreased cerebral perfusion/ischemia → cell death/infarction → loss of function

Caused by thrombosis or Embolis

  • Thrombosis (blood clot) of cerebral arteries or intracranial vessels that occludes BF

    • Causes congestion and edema in vessel which leads to ischemia

  • Embolism from a thrombus outside of brain (aorta, heart, common carotid artery)

    • Curs off circulation causes necrosis and edema

Renal Gerontologic Considerations

  • GFR decreases between ages 35 to 40yrs

    • 1 mL/min continues thereafter each year

  • Older adults susceptible to acute and chronic kidney injury

  • Older adults are more prone to develop hypernatremia and fluid volume deficit, because increasing age is also associated with diminished osmotic stimulation of thirst

  • Slow response to sudden physiologic changes

  • Diminished osmotic stimulation of thirst

  • Urinary incontinence is present in 15% to 30% of community-dwelling older adults, 50% of older adults who are institutionalized, and 30% of older adults who are hospitalized

  • Incomplete emptying of the bladder

  • A fluid balance deficit in older adults can lead to falls, medication toxicity, constipation, urinary tract and respiratory tract infections, delirium, seizures, electrolyte imbalances, hyperthermia, and delayed wound healing.

Lower Urinary Tract Infections

Causes: bacteria colonize the urinary tract, backward flow of urine from the bladder into the ureters, obstruction of free flowing urine

  • The most common cause of UTIs occur when fecal organisms ascend from the perineum to the urethra and bladder

Cystitis

  • (inflammation of the urinary bladder),

Prostatitis

  • (inflammation of the prostate gland), and bacterial

urethritis

  • inflammation of the urethra)

  • Females at greater risk due to short urethra

  • Assess patients for dysuria, frequency, urgency, nocturia, incontinence, suprapubic or pelvic pain, UA, Urine C&S

  • Bacteriuria increases with age (women > men)

  • UTI is the most common infection of elderly

  • Initiate ABT orders – decrease s/s, prevent complications

  • Encourage fluids to flush bacteria and promote renal blood flow

  • Patient education. Review “Nursing Process – The Patient with a Lower Urinary Tract Infection”

Heart Failure: Interventions

  • Pharmacologic

    • Diuretic

    • Beta blockers

  • Iv Infusion of Inotropic

    • Inotropic agents, or inotropes, are drugs that change the force of a heart's contractions. Inotropes can be positive or negative, depending on whether they strengthen or weaken the heartbeat

    • Positive inotropes

    • Used when the heart is too weak to pump enough blood, such as when the heart can't get enough blood to the body. Positive inotropes strengthen the heart's contractions, which increases cardiac output and the amount of blood the heart pumps.

    • Negative inotropes

    • Used when the heart is working too hard, such as when a patient has high blood pressure, chest pain, or an abnormal heart rhythm. Negative inotropes weaken the heart's contractions.

    • Examples of positive inotropic medications include digoxin, dobutamine, and milrinone.

    • Clonidine and Atenolol are examples of negative inotropic medications

  • Nutritional therapy

    • Dash diet

    • Low sodium

    • No canned food

58
New cards

Pump Failure

  • Inadequate peripheral blood flow occurs when the heart’s pumping action becomes inefficient

  • Heart failure with reduced left ventricular ejection fraction (HFrEF; also called systolic HF) causes an accumulation of blood in the lungs and a reduction in forward flow or cardiac output, which results in inadequate arterial blood flow to the tissues.

  • Heart failure with preserved left ventricular ejection fraction (HFpEF; also called diastolic HF) causes systemic venous congestion and a reduction in forward flow

Angina Pectoris

  • Angina=chest pain

    • A Syndrome characterized by episodes or paroxysmal pain or pressure in the anterior chest caused by insufficient coronary blood flow

    • SOB, diaphoresis, palpitations, fatigue, N/V

    • Physical exertion or emotional stress increases myocardial oxygen demand, and the coronary vessels are unable to supply sufficient blood flow to meet the oxygen demand

    • Can radiate across chest to arms, jaw, shoulders, upper back or epigastrium

      • Radiation to arm and hands described as numbness and tingling

  • Stable angina: more O2 than heart can handle

  • Unstable: acute coronary syndrome. It is characterized by sudden and unexpected chest pain, typically while at rest, and it can persist longer than stable angina. This condition is a sign that your heart is not getting enough oxygen, and it requires immediate medical intervention.
