Myelopathy due to electrical injury
Introduction
Introduction to spinal cord disease caused by electric shock Electric shock is more common. In addition to direct burns, visceral injury and sudden cardiac arrest, electric shock can cause damage to the brain, spinal cord and peripheral nerves, and can also cause neurological disorders. Spinal cord disease caused by electric shock is more common when exposed to high-voltage current, and a small number of spinal cord injuries are caused by accidental contact with household electrical power. basic knowledge Sickness ratio: 0.0001% Susceptible people: no specific people Mode of infection: non-infectious Complications: disturbance of consciousness acne
Cause
Causes of myelopathy caused by electric shock
(1) Causes of the disease
The spinal cord electric shock can occur after exposure to 75 to 75,000 volts. When the electric shock strikes, the heartbeat can be arrested, causing the systemic blood circulation to pause and causing systemic hypoxia. If the death is spared at the time, most of the brain and spinal cord syndrome remains. In the event of an electric shock, if the current is transmitted from one hand to the other, it can also cause damage to the part due to current flowing through the spinal cord of the neck.
(two) pathogenesis
Spinal cord damage can be caused by direct neuronal damage, or by thrombosis of blood vessels supplying the spinal cord. Neuropathic degeneration, anterior horn cell destruction and glial cell enlargement can be seen in the pathological section of the spinal cord.
Prevention
Prevention of spinal cord disease caused by electric shock
prevention:
1. Pay attention to safety regulations and use electricity to prevent electric shock.
2. Early treatment of electric shock patients, early use of vitamin B family and neurotrophic drugs, have a certain effect on improving the function of damaged neurons.
3. The first thing is to immediately remove the injured person from the power supply and immediately cut off the power. Use dry sticks or other insulation to turn the power off, and avoid using electric shock by hand. You can't forget your safety because you are eager to save people.
Complication
Complications of myelopathy caused by electric shock Complications, dysfunction, acne
Other manifestations of electric shock, such as skin burns, sudden cardiac arrest, convulsions, disturbance of consciousness, and acne and cystitis caused by prolonged bed rest are also prone to occur.
Symptom
Symptoms of myelopathy caused by electric shock Common symptoms Sensory disorder edema, palpitation, muscle atrophy, demyelinating myelopathy
1. The clinical manifestations of electroporotic myelopathy can coexist with other systemic electrical injury manifestations, which can be temporary or permanent.
2. Temporary symptoms, more immediately after the electric shock, and recovered within a few days, common conscious disturbances, limb weakness, autonomic dysfunction (hyperactivity, palpitation, urinary dysfunction), sensory disturbances.
3. Permanent, the symptoms and signs can occur from a few days to several months after the electric shock, often have upper limb weakness and muscle atrophy, lower extremity spasm, feeling symptoms are generally light, may have dysfunction, sometimes these Symptoms develop progressively and may be associated with degeneration of the nerve bundle or secondary edema with demyelinating lesions.
4. The course of the disease is generally not progressing.
5. Cerebrospinal fluid examination is normal.
Examine
Examination of myelopathy caused by electric shock
1. Cerebrospinal fluid examination of the spinal canal is smooth, normal pressure, normal or slightly elevated protein, slightly increased or normal cell number, normal chloride.
2. Other blood tests include liver function, kidney function, blood sugar, blood sedimentation routine examination; rheumatism series, immunoglobulin electrophoresis and other serological tests related to autoimmunity, have differential diagnosis significance.
3. Electromyography and neurophysiological examination have the significance of auxiliary diagnosis.
4. Spinal cord CT, MRI examination, has a differential diagnosis value.
Diagnosis
Diagnosis and diagnosis of myelopathy caused by electric shock
With a history of electric shock injury and spinal cord lesions, the disease can be considered.
Attention should be paid to the identification of other spinal cord lesions, especially those that may have occurred before the electric shock, such as syringomyelia, spinal cord tumor, spinal cord compression.
