What is Neurogenic Shock?

Neurogenic shock is a distributive type of shock.

In neurogenic shock, vasodilation occurs as a result of a loss of balance between parasympathetic and sympathetic stimulation.

It is a type of shock (a life-threatening medical condition in which there is insufficient blood flow throughout the body) that is caused by the sudden loss of signals from the sympathetic nervous system that maintain the normal muscle tone in blood vessel walls.

The patient experiences the following that results in neurogenic shock:

Stimulation. Sympathetic stimulation causes vascular smooth muscle to constrict, and parasympathetic stimulation causes vascular smooth muscle to relax or dilate.
Vasodilation. The patient experiences a predominant parasympathetic stimulation that causes vasodilation lasting for an extended period of time, leading to a relative hypovolemic state.
Hypotension. Blood volume is adequate, because the vasculature is dilated; the blood volume is displaced, producing a hypotensive (low BP) state.
Cardiovascular changes. The overriding parasympathetic stimulation that occurs with neurogenic shock causes a drastic decrease in the patient’s systemic vascular resistance and bradycardia.
Insufficient perfusion. Inadequate BP results in the insufficient perfusion of tissues and cells that is common to all shock states.

Neurogenic shock could be caused by the following:

స్పైనల్ cord injury. Spinal cord injury (SCI) is recognised to cause hypotension and bradycardia (neurogenic shock).
Spinal anesthesia. Spinal anesthesia—injection of an anesthetic into the space surrounding the spinal cord—or severance of the spinal cord results in a fall in blood pressure because of dilation of the blood vessels in the lower portion of the body and a resultant diminution of venous return to the heart.
Depressant action of medications. Depressant action of medications and lack of glucose could also cause neurogenic shock.

The clinical manifestations of neurogenic shock are signs of parasympathetic stimulation

Dry, warm skin. Instead of cool, moist skin, the patient experiences dry, warm skin due to vasodilation and inability to vasoconstrict.
Hypotension. Hypotension occurs due to sudden, massive dilation.
Bradycardia. Instead of getting tachycardic, the patient experience bradycardia.
Diaphragmatic breathing. If the injury is below the 5th cervical vertebra, the patient will exhibit diaphragmatic breathing due to loss of nervous control of the intercostal muscles (which are required for thoracic breathing).
Respiratory arrest. If the injury is above the 3rd cervical vertebra, the patient will go into respiratory arrest immediately following the injury, due to loss of nervous control of the diaphragm.

అసెస్‌మెంట్ మరియు డయాగ్నస్టిక్ ఫలితాలు

Diagnosis of neurogenic shock is possible through the following tests:

Computerized tomography (CT) scan. A CT scan may provide a better look at abnormalities seen on an X-ray.
Xrays. Medical personnel typically order these tests on people who are suspected of having a spinal cord injury after trauma.
Magnetic resonance imaging (MRI). MRI uses a strong magnetic field and radio waves to produce computer-generated images.

వైద్య నిర్వహణ

Treatment of neurogenic shock involves:

Restoring sympathetic tone. It would be either through the stabilization of a spinal cord injury or, in the instance of spinal anesthesia, by positioning the patient appropriately.
స్థిరీకరణ. If the patient has a suspected case of spinal cord injury, a traction may be needed to stabilize the spine to bring it to proper alignment.
IV fluids. Administration of IV fluids is done to stabilize the patient’s blood pressure.

ఫార్మకోలాజిక్ థెరపీ

Drugs administered to a patient undergoing neurogenic shock are:

Inotropic agents. Inotropic agents such as dopamine may be infused for fluid resuscitation.
Atropine. Atropine is given intravenously to manage severe bradycardia.
Steroids. Patient with obvious neurological deficit can be given I.V. steroids, such as methylprednisolone in high dose, within 8 hours of commencement of neurogenic shock.
Heparin. Administration of heparin or low molecular-weight heparin as prescribed may prevent thrombus formation.

Nursing management of a patient with neurogenic shock includes:

నర్సింగ్ అసెస్‌మెంట్

Assessment of a patient with neurogenic shock should involve:

ABC assessment. The prehospital provider should follow the basic airway, breathing, circulation approach to the trauma patient while protecting the spine from any extra movement.
Neurologic assessment. Neurologic deficits and a general level at which abnormalities began should be identified.

నర్సింగ్ నిర్ధారణ

Based on the assessment data, the nursing diagnoses for a patient with neurogenic shock are:

Risk for impaired breathing pattern related to impairment of innervation of diaphragm (lesions at or above C-5).
Risk for trauma related to temporary weakness/instability of వెన్నెముక కాలమ్.
Impaired physical mobility related to neuromuscular impairment.
Disturbed sensory perception related to destruction of sensory tracts with altered sensory reception, transmission, and integration.
Acute pain related to pooling of the blood secondary to thrombus formation.

నర్సింగ్ జోక్యం

Nursing interventions are directed towards supporting cardiovascular and neurologic function until the usually transient episode of neurogenic shock resolves.
Elevate head of bed. Elevation of the head helps prevent the spread of the anesthetic agent up the spinal cord when a patient receives spinal or epidural anesthesia.
Lower extremity interventions. Applying anti-embolism stockings and elevating the foot of the bed may help minimize pooling of the blood in the legs and prevent thrombus formation.
Exercise. Passive range of motion of the immobile extremities helps promote circulation.
Airway patency. Maintain patent airway: keep head in neutral position, elevate head of bed slightly if tolerated, use airway adjuncts as indicated.
Oxygen. Administer oxygen by appropriate method (nasal prongs, mask, intubation, ventilator).
Activities. Plan activities to provide uninterrupted rest periods and encourage involvement within individual tolerance and ability.
BP monitoring. Measure and monitor BP before and after activity in acute phases or until stable.
Reduce anxiety. Assist patient to recognize and compensate for alterations in sensation.
