What is lumbar puncture and is there any harm in lumbar puncture?

Lumbar puncture is the most common examination in neurology, which is simple to perform, has fewer complications, and takes less time if the patient cooperates well. Many diseases in neurology need to be identified by lumbar puncture, such as inflammatory lesions of the central nervous system, including meningitis and encephalitis caused by various causes. In addition, there are spinal cord lesions and multiple radiculopathies, which can be diagnosed by lumbar puncture.

Of course, there are also complications of lumbar puncture, such as headache, which is the most common complication of lumbar puncture, which is caused by low intracranial pressure. There are also complications such as bleeding at the puncture site and infection, but so far, lumbar puncture is relatively rare and rarely occurs.

Lumbar puncture is a common examination technique in neurology. It is mainly used for differential diagnosis of diseases, such as headache, fever, psychiatric symptoms, etc., and lumbar puncture to check cerebrospinal fluid to identify whether it is encephalitis. Lumbar puncture for cerebrospinal fluid examination is of great significance, so there are no contraindications, and lumbar puncture** is recommended.

However, because the lumbar puncture passes through the fascial muscles, nerves, blood vessels, etc., there is a possibility that some nerve damage may occur. For example, low back pain after lumbar puncture, low cranial pressure headache, etc. Generally, after lumbar puncture, lie flat for more than 8 hours, drink more water, local hot compress, etc., and generally there will be no sequelae.

Question 1: When to make a lumbar puncture 1 diagnosis of inflammatory lesions of the brain and spinal cord.

2 Diagnosis of vascular lesions of the brain and spinal cord.

3 Distinguish between obstructive and non-obstructive spinal cord lesions.

4 Pneumoencephalography and spinal membrane iodium.

5 Diagnostic puncture for early intracranial hypertension.

6 Intrathecal administration.

7 Subarachnoid hemorrhage releases a small amount of bloody cerebrospinal fluid to relieve symptomsQuestion 2: Under what circumstances does a child need to have a lumbar puncture? Because the blood is too high, so this situation is necessary to do lumbar puncture, this lumbar puncture has no effect on the child, you can rest assured, because even if the puncture, if it will not go up to the child's nerves, this can be assured, but the lumbar puncture is of great help to the diagnosis of the child's disease, so it is still carried out quickly.

Question 3: What is the main purpose of lumbar puncture? Is it serious?

Analysis: Hello, the main purpose of lumbar puncture is to check the cerebrospinal fluid biochemistry routine or culture. Lesions of the brain and spinal cord or vascular disease can be diagnosed.

It is a relatively minor puncture surgery. Don't worry. Suggestions:

After the operation, you should go to the pillow and lie flat for four to six hours, keep the wound dry and clean, and report any discomfort to the medical staff in time.

Question 4: Under what circumstances does a child over 1 year old need to have a lumbar puncture Unscrupulous doctors urgently need to complete this month's billing task arranged by the hospital!

Question 1: What does lumbar puncture mean Lumbar puncture, take bone marrow for experiments.

Question 2: What is lumbar puncture Lumbar puncture, from the back, after positioning, use a puncture needle to enter different parts of the vertebrae, extract cerebrospinal fluid or anesthesia, etc.

Question 3: What is lumbar puncture Leukemia is a serious disease in which leukemia cells invade various organs of the patient's body. In particular, acute lymphoblastic leukemia has a high incidence of central nervous system leukemia.

The diagnosis of central nervous system leukemia is mainly based on a lumbar puncture (i.e., lumbar puncture), which is analyzed and diagnosed by measuring the pressure of the cerebrospinal fluid and checking the number of cells, proteins, and sugars in the cerebrospinal fluid. If leukemia cells are found in the cerebrospinal fluid, it is the basis for diagnosis. Once central nervous system leukemia is diagnosed, lumbar puncture, which is the injection of chemotherapy drugs into the cerebrospinal fluid through lumbar puncture.

In addition, after each lumbar puncture to extract cerebrospinal fluid (CSF), an appropriate amount of chemotherapy drugs is routinely injected into the cerebrospinal fluid, which is also of positive significance for the prevention of central nervous system leukemia. Therefore, lumbar puncture is both a diagnosis and the main means of prevention and treatment of central nervous system leukemia

Question 4: What is the definition and difference between bone puncture and lumbar puncture? Please detail 10 points 1Bone marrow is taken for laboratory examination, and lumbar puncture is used for cerebrospinal fluid examination.

2.The site of bone puncture is the iliac bone, and the site of lumbar puncture is the lumbar spine.

3.Bone puncture is a must for blood diseases, and lumbar puncture is a must for meningitis.

Do lumbar wear suitable for:

1.Diagnosis and differential diagnosis of inflammatory diseases of the central nervous system include purulent meningitis, tuberculous meningitis, viral meningitis, fungal meningitis, Japanese encephalitis, etc.

2.The diagnosis and differential diagnosis of cerebrovascular accident include cerebral hemorrhage, cerebral infarction, and subarachnoid hemorrhage.

3.Diagnosis of neoplastic disease with ** For the diagnosis of meningeal leukemia and intrathecal injection of chemotherapy drugs by lumbar puncture** meningeal leukemia.

The main purpose of doing lumbar puncture is as follows:

1. Understand whether the intracranial pressure and cerebrospinal fluid circulation pathway are smooth;

2. Cerebrospinal fluid (CSF) for examination: routine, biochemical, bacteriological examination, tumor cell examination, etc.;

3. Release bloody cerebrospinal fluid or high-protein cerebrospinal fluid;

4. Intrathecal injection (spraying).

Laboratory tests of bone marrow fluid to diagnose encephalitis.

Lumbar puncture is one of the commonly used examination methods in neurology, which is of great value for the diagnosis of neurological diseases, simple and easy, and relatively safe; However, if the indications are not properly grasped, the mild case can aggravate the original condition, and the severe case may even endanger the safety of the patient.

Indications lumbar puncture.

1.Diagnosis and differential diagnosis of inflammatory diseases of the central nervous system include purulent meningitis, tuberculous meningitis, viral meningitis, fungal meningitis, Japanese encephalitis, etc.

2.The diagnosis and differential diagnosis of cerebrovascular accident include cerebral hemorrhage, cerebral infarction, and subarachnoid hemorrhage.

3.Diagnosis of neoplastic disease with ** For the diagnosis of meningeal leukemia and intrathecal injection of chemotherapy drugs by lumbar puncture** meningeal leukemia.

4.Measuring intracranial pressure and finding out if the subarachnoid space is blocked, etc.

5.Neuraxial administration.

2 contraindications. 1.Suspicion of intracranial hypertension and cerebral herniation. 2.

Suspicious intracranial mass lesions. 3.Critically ill patients such as shock.

4.There is inflammation at the puncture site. 5.

Patients with severe coagulation disorders, such as hemophilia, etc.

Analysis: Hello, the main purpose of lumbar puncture is to check the cerebrospinal fluid biochemistry routine or culture. Lesions of the brain and spinal cord or vascular disease can be diagnosed. It is a relatively minor puncture surgery. Don't worry.

Suggestions: After surgery, you should go to the pillow and lie flat for four to six hours, keep the wound dry and clean, and tell the medical staff in time if you have any discomfort.
