Cerebrospinal fluid CSF Determine what exactly is cerebrospinal fluid

In appearance, cerebrospinal fluid is colorless, transparent, and has very low viscosity.

Cerebrospinal fluid (CSF) is a clear, yellowish fluid that is about 40 to 60 milliliters in infancy, 60,100 milliliters in early childhood, 80,120 milliliters in adolescence and 150,200 milliliters in adulthood.

Cerebrospinal fluid (CSF) is living water, which is constantly being produced in about milliliters per minute, and is constantly absorbed in about equal amounts. In this way, it maintains a constant number from moment to moment, week to week. Driven by the cerebral vascular pulse, it circulates along a certain route through several ventricles.

Cerebrospinal fluid day and night"Walk around"What exactly is it up to? It turns out that cerebrospinal fluid is not nothing"Clear water"It contains protein, glucose, chloride, etc., which can bring essential nutrients to the brain and spinal cord, and can also bring unnecessary and harmful waste products from the brain and spinal cord to the blood and secrete them.

In addition, there is a certain amount of cerebrospinal fluid"Barrier effect", which prevents certain bacteria, viruses or harmful substances from invading the brain and spinal cord.

After all, the brain and spinal cord can still get sick, and even bacteria and viruses can get into them and harm them. At this time, the doctor will often do a puncture examination from the back of the lumbar spine and take out a little cerebrospinal fluid for testing to help diagnose the disease according to the composition of the cerebrospinal fluid. In some patients, symptoms such as severe headaches due to increased pressure in the brain case (intracranial) may also be used to remove some cerebrospinal fluid to reduce pressure within the skull if needed.

Because the cerebrospinal fluid is constantly circulating, the brain and spinal cord are diseased, and sometimes drugs can be injected directly into the cerebrospinal fluid to borrow the cerebrospinal fluid"Walk around"The drug is delivered directly to the diseased area to achieve the purpose of treatment.

Cerebrospinal fluid must not be without, nor can it be excessive, let alone turbid and deteriorated, otherwise it is pathological.

Cerebrospinal fluid from? How much cerebrospinal fluid does the body produce per day? Be careful.

Cerebrospinal fluid is a colorless and transparent fluid that exists in the skull, with a total amount of about 140 ml, which can buffer external force, reduce **, and protect the brain and spinal cord. It also has an important function of transporting nutrients to the brain and spinal cord and carrying away the waste products produced. Cerebrospinal fluid is constantly produced and absorbed.

If the arachnoid membrane and meninges are torn due to trauma, surgery, or other reasons, and cerebrospinal fluid flows out, it is called"Cerebrospinal fluid leakage", leakage from the nostrils is called"Cerebrospinal fluid rhinorrhea", leaking out of the ear is called"Cerebrospinal fluid otorrhoea", leakage from the incision after surgery is called"Incisional cerebrospinal fluid leak"。More information** (click to view).

Cerebrospinal fluid leakage can lead to neurological infections in 2% to 9% of cases. Infected patients will have high fever, headache, nausea, vomiting, severe patients will also have impaired consciousness, personality changes, forgetfulness, abnormal behavior, unable to speak, even hallucinations, rhapsodic thoughts, and one patient may even be mistakenly admitted to a psychiatric hospital due to psychiatric symptoms. Some also have convulsions (epilepsy) and can die within a number of severe cases.

When the capsule of cerebrospinal fluid is damaged and there is a thin mouth, the fluid will flow out, and the causes of cerebrospinal fluid leakage are: trauma damage to the meninges, tumor invasion of the meninges and leakage, and poor meningeal suture after surgery.

Diagnosis: Cerebrospinal fluid (CSF) has a unique appearance on laboratory tests, and a small amount of leakage can be taken for laboratory testing to confirm the diagnosis. Sometimes the location of the leak is difficult to find, and tests such as radionuclide testing are needed to confirm the diagnosis.

Cerebro-spinal fluid (CSF) is a colorless, transparent fluid that fills the ventricles, subarachnoid space, and spinal canal**. Cerebrospinal fluid (CSF) is produced by the choroid plexus in the ventricles and is slightly viscous in nature similar to plasma and lymphatic fluid.

Under normal circumstances, cerebrospinal fluid has chloride, sodium, magnesium, CO2, ethanol, etc.; Partial albumin, urea, creatinine, uric acid, amino acids, glucose, calcium, lactic acid, acetone, enzymes, etc. The difference with the components in the blood is the absence of bilirubin, fibrinogen, complement, antibodies, cholesterol, etc.

Cerebrospinal fluid (CSF) is located in the subarachnoid space of the brain and spinal cord and is a clear, yellowish fluid that nourishes the brain and spinal cord.

Can cerebrospinal fluid be in Kunming**.

Characteristics of normal cerebrospinal fluid: colorless, transparent fluid, slightly viscous.

Where is the cerebrospinal fluid leak? Is cerebrospinal fluid rhinorrhea, otorrhoea, or incision leak? Is there a history of trauma?

If there is trauma, the base of the skull may be damaged, and rhinorrhea or ear discharge may occur. Some brain surgeries may have leaky incisions (of course, skull base surgery can also produce rhinorrhea and otorrhea).

The nature of normal cerebrospinal fluid (CSF) looks like boiled water, and it is often combined with bleeding from surrounding tissues during trauma, so the cerebrospinal fluid leakage caused by it is mostly manifested as "blood water" or "meat washing water".

In general, this CSF leak usually stops and disappears within a few days of self-healing and closing, during which time antibiotics are given to prevent reflux of CSF and cause intracranial infection (intracranial infection has a high mortality rate). If the incision leak is a leak, local debridement and suturing are required. If the cerebrospinal fluid leak does not heal on its own for a long time, surgery is needed to repair the dura mater.
