What Is Viremia?

Viremia (viremia, virusemia) When the virus enters the human body, it first enters the blood, causing viremia, and then can invade the whole body organs or the central nervous system; it can also directly invade the central nervous system. When viral encephalitis occurs, it often causes changes in inflammation, edema, and necrosis of nerve cells, and a series of clinical manifestations appear. When inflammation spreads to the meninges, it is called viral meningoencephalitis.

Overview of viremia disorders

Viremia (viremia, virusemia) When the virus enters the human body, it first enters the blood, causing viremia, and then can invade the whole body organs or the central nervous system; it can also directly invade the central nervous system.

When inflammation spreads to the meninges, it is called viral meningoencephalitis.

Viremia viral encephalitis

I. Introduction

1. Viral encephalitis (referred to as diseased brain) is a group of infectious diseases of the central nervous system caused by mental and conscious disturbances caused by various viruses.

2. More than 1 to 3 weeks before the illness, a history of upper respiratory and gastrointestinal infections, and a history of animal or insect bites.

3. The severity of the disease ranges from mild to severe, which can be relieved on its own, and severe cases can cause sequelae or death.

Second, the nursing method of high fever

1, the body temperature rise stage: pay attention to keep warm when shivering.

2. Fever duration: Pay attention to replenishing water when applying antipyretics.

3. Antipyretic phase: change sweaty clothes in time to prevent cold.

4, pay attention to oral cleansing and skin cleanliness, eat a light, digestible diet, such as lean meat porridge, noodles, green soup and so on.

3. Early exercise for physical function and early recovery

1. Let the child's paralyzed limb be in a functional position.

2. For sober children, we should pay more attention to them, be considerate, and enhance their self-care ability and confidence.

3. Frequently communicate with children to promote the recovery of their language functions.

4. Early massage and flexion of the limb muscles of children.

5. In the recovery period, encourage and assist the children in active limb exercise.

6, step by step, pay attention to safety and prevent injuries.

4. Why do children with encephalitis do lumbar puncture (referred to as lumbar puncture)?

(A) the purpose of lumbar puncture

1. Checking the properties of cerebrospinal fluid is of great significance for the diagnosis of encephalitis and meningitis.

2. For lumbar spine anesthesia, intrathecal injection of drugs for treatment.

3. Measure intracranial pressure and understand whether the subarachnoid space is blocked or bleeding.

(Two) precautions after lumbar puncture

After the operation, the child was placed on the pillow for 4-6 hours. Prevent headaches and vomiting caused by getting up too early.

Viral encephalitis is inflammation of the brain parenchyma caused by a viral infection.

Causes When the virus enters the human body, it first enters the blood, causing viremia, and then it can invade systemic organs or the central nervous system; it can also directly invade the central nervous system. When viral encephalitis occurs, it often causes changes in inflammation, edema, and necrosis of nerve cells, and a series of clinical manifestations appear. When inflammation spreads to the meninges, it is called viral meningoencephalitis.

[Symptoms] The severity of viral encephalitis varies widely. There are both those with high fever and those with low fever. Usually have varying degrees of headache, vomiting, poor mental complexion, sleepiness and sleepiness. Severe cases may have convulsions, coma, limb paralysis, and irregular breathing rhythms. Because of the different types of viruses, the manifestations of encephalitis are diverse. Epidemic Japanese encephalitis (JE) is transmitted by mosquitoes carrying viruses and is most likely to cause high fever, convulsions and coma. Sudden onset, rapid progress, disability and mortality are high.

Encephalitis caused by herpes simplex virus is also very serious. Not only does the brain have inflammation and edema, but bleeding and necrosis also occur.

Mumps encephalitis is a complication of mumps. In addition to the swelling and pain of the parotid glands, symptoms such as headache and vomiting gradually appear, suggesting that the brain may be damaged. Some patients have symptoms of encephalitis only after mumps has improved. Very few patients have no symptoms of mumps, and it is the manifestation of encephalitis from the beginning.

Viral encephalitis can be diagnosed by clinical manifestations, cerebrospinal fluid test, electroencephalogram, and CT. A few qualified hospitals can perform specific antibody or virus isolation. With a view to further clarify the pathogen.

Treatment Antiviral treatment can be used for confirmed or suspected patients. For those with herpes simplex virus, acyclovir can be used; for those with other viruses, ribavirin and integrated traditional Chinese and western medicine can be used.

The prognosis of viral encephalitis is closely related to the pathogen. The prognosis of herpes simplex virus is poor. Many surviving patients have sequelae of varying degrees.

In addition to physical exercise, injecting various antiviral vaccines is the fundamental way to prevent viral encephalitis.
