Modern medicine has a huge range of all kinds of ways to identify diseases and identify the true causes that caused them.
Diagnostic methods
Among the most popular and informative types of diagnostics are the following:
Laboratory research;Ultrasound procedure;
X-ray examination;
Electrographic studies.
Here you should pay attention to a very special research method - diagnostic puncture... This method is relatively new. It gained its popularity due to its comprehensive informational content and the fact that by a similar method it is possible to obtain information about almost any organ, substance or tissue of the human body. Let's get to know this method together, find out all its advantages and features.
What is a puncture?
The medical term is puncture, translated from Latin means an injection or puncture. This is a special medical procedure in which tissue is taken using fine special needles. When carrying out such manipulations, specialists receive the material necessary for comprehensive research. It can be a piece of tissue or organ, a certain amount of intercellular, intervertebral, lymphatic, secretory or blood fluid. Also, using this procedure, you can investigate any pathological formation in the body. In such cases, the doctor gets his hands on invaluable material, the results of the research of which are used to prescribe the only correct treatment. The most informative in this regard can be considered the collection of cerebrospinal fluid, since this substance is in direct relationship with the nervous system and the general blood flow of a person. In special cases, when the diagnosis is questioned by several doctors, it is the diagnostic puncture that unconditionally clarifies the patient's condition. To do this, the specialist makes a puncture over the organ or tissue that needs to be examined and takes a small number of samples.
How are the different types of puncture performed?
Note that such an event is carried out in a temporary hospital. In other words, to carry out the manipulations, it is enough to spend thirty minutes in a specially prepared office with a specialized manipulation table. There are a fairly large number of types of punctures, and they are carried out in such a way that the specialist has maximum access to the examined organ, tissue or cavity. With spinal punctures, the patient lies on his side in the embryo position, pulling the knees up to the abdomen as far as possible. In this position, the intervertebral clefts increase and access to the intervertebral trunk becomes easier.
At diagnostic puncture joints, the patient is in a sitting position, and the doctor punctures the bursa, trying to extract its contents. With sternal puncture, after disinfecting the skin over the examined bone tissue, and anesthetizing this area with any of the anesthetic drugs, the doctor inserts a needle into the tissue until it rests on the bone. Further, the doctor continues to insert the needle until he feels a decrease in resistance and a characteristic crackling of the bone marrow tissue is heard. This type of puncture is used to determine diseases of hematopoiesis. In diseases of the lungs, pleural puncture is very often used to identify the true causes of the disease. With pulmonary diseases, fluid accumulates in the interpleural region.
Such an accumulation significantly aggravates the general condition of the patient. The study allows you to establish the nature of the accumulated fluid and identify the presence of disease-causing and pathological cells in it. During the procedure, the patient is in a sitting position, bending his back and tilting his head slightly forward. A needle is inserted into the interpleural space, connected to a tube and a pump, which will slowly and carefully suck out the fluid. After withdrawing the required amount of fluid, the tube is pinched and the needle is removed. After treating the puncture site with iodine, it is sealed with a plaster.
In cases where you need to receive treatment or undergo a thorough diagnosis, the most correct solution would be if you take advantage of the experience and knowledge of specialists and unique equipment that are successfully working in our new medical center. Our medical base and modern medical and surgical equipment allow us to quickly and with a guarantee get rid of many insidious and dangerous diseases.

Puncture - taking a tissue sample for analysis. It is carried out through a puncture of an organ or neoplasm. In addition to the diagnostic purpose, this procedure can also be performed for medicinal purposes. And today we will tell you in detail what it is puncture, does it hurt how it is done.
Why is a puncture performed?
For diagnostic purposes, a puncture is performed by injecting a contrast agent, for taking tissue for analysis and for monitoring the pressure in various vessels. If the procedure is carried out for the purpose of treatment, medications are injected into the organ or cavity. In addition, with the help of puncture, excess liquid or gas is removed, and the organ is flushed.
What types of punctures are there?
This procedure is used for different purposes and is carried out over different organs. Therefore, the puncture is divided into several types:
... Pleural puncture;Spinal cord puncture;
Sternal;
Liver biopsy;
Kidney biopsy;
Puncture of the joint;
Follicle puncture;
Puncture of the mammary gland;
Puncture of the thyroid gland;
Umbilical cord puncture or cordocentesis;
Puncture of the ovarian cyst.
Diagnostic puncture
In most cases, this manipulation takes place under general or local anesthesia. In this case, the question puncture, does it hurt we can say that the procedure is completely painless. In cases where the procedure is performed without anesthesia, it feels like a regular injection during a vaccination. For the puncture, a thin hollow needle is used, which is carefully inserted into the desired area, for example, into a cyst. Then, with a syringe, the internal fluid is sucked out. When the sample is received, it is sent for further histological examination in the laboratory. Depending on the organ, the procedure and the needle used may differ slightly, but in any case, the principle remains the same.
Usually, a puncture does not take more than 15 minutes, although 1 minute is enough for the puncture itself. The patient can be in a sitting or lying position, depending on the objectives of the study. Do not move while taking the sample. If the patient moves involuntarily, the needle can damage nearby tissues or blood vessels. This will lead to unpleasant consequences.
Curative puncture
For medicinal purposes, the puncture is carried out in the same way. To reduce pain, anesthesia is performed. The puncture site is treated with alcohol or iodine solution. The only difference is that healing solutions are pumped in or excess fluid is removed. If fluid is pumped out of the tumor, then it is sent for further study to the laboratory. This is necessary in order to accurately determine the cause of the appearance of the neoplasm and thereby prevent relapse. The procedure can be repeated several times. If indicated, it is used for both adults and children. The duration of the puncture in this case is on average 20 minutes, it depends on the organ being manipulated.
After the procedure
In most cases, after a puncture, rehabilitation is not required, but if necessary, it can last from 2 hours to a day. During this time, the patient is in the clinic, under the supervision of health workers. This is necessary to prevent possible complications. After a puncture, minor pain, lethargy and nausea may appear. These are the consequences of the action of anesthesia and puncture. All these sensations go away on their own, but various medications, including pain relievers, can also be prescribed. Both during and after the procedure, the patient does not experience serious pain. Therefore, a puncture is considered a painless and safe procedure. In our center, the puncture is performed quickly and efficiently. You will not feel any pain. Come to our center in Moscow, we will definitely help you!
A lumbar spinal tap is a diagnostic procedure in which a needle is inserted into the lumbar region to obtain a sample of cerebrospinal fluid. Also, a puncture of the spine (or, as it is also called, a lumbar puncture) can be performed for anesthetic or therapeutic purposes. More details about the procedure will be discussed in this article.
A lumbar puncture is prescribed in such cases:
Based on the results of the tests performed, the doctor will be able to detect pathogenic microorganisms of viral and fungal origin, including encephalitis, meningitis and syphilis. Also, a puncture of the spine allows detect some cancers affecting the patient's brain or spinal cord, intracerebral hemorrhage or inflammation of the central nervous system.
If you want to know in more detail how to correctly identify the disease, as well as consider the symptoms and manifestations of the disease, you can read an article about this on our portal.
Diagnosis of diseases
Based on the results of a lumbar puncture, various pathologies can be diagnosed, ranging from multiple sclerosis or meningitis, to cancers affecting the spinal cord. Below are the most commonly diagnosed pathologies.
Table. Diseases that can be detected with a lumbar puncture.
| Disease | Short description |
|---|---|
| A common infectious disease that affects the lining of the brain or spinal cord. In rare cases, the inflammatory process can immediately spread to both the spinal cord and the patient's brain, which greatly complicates the treatment process. |
| Disease of the nervous system, which is accompanied by the development of an infectious process. During the development of the disease, the causative agent of syphilis penetrates into the nervous tissue, resulting in unpleasant symptoms. |
| Acute polyradiculoneuropathy of inflammatory nature. The main symptom of GBS is the development of protein-cell dissociation or peripheral paralysis. Also, the patient may face autonomic disorders, decreased sensitivity and flaccid paresis. |
| The accumulation of purulent mass against the background of the development of a local chronic infection. As a result, tissue structure is destroyed in the focus of inflammation. An abscess occurs when various microbes enter the body. This usually occurs through wounds, punctures, or abrasions on the body. |
| A common autoimmune disease of a chronic nature that affects the spinal cord and brain. In the process of the development of pathology, the patient's nervous tissue is destroyed, and in its place a scar is formed. |
| A very dangerous oncological disease, which is accompanied by a squeezing effect, which negatively affects the patient's spinal cord. |
Note! In addition to diagnosing various pathologies, a puncture of the spine is often carried out with the aim of introducing a drug into the patient's body. This procedure is usually required during chemotherapy.
Potential consequences and risks
Despite its effectiveness, lumbar puncture is a very dangerous procedure... Only an experienced specialist can take a puncture correctly, because this requires not only special surgical instruments, but also deep knowledge of medicine. If the puncture technique is not followed or errors are made, serious complications can arise:
- Strong headache;
- the appearance of discomfort in the spine;
- internal bleeding;
- increased pressure in the skull;
- the formation of protrusions or hernias;
- the appearance of a tumor-like formation (cholesteatoma).
Often, after performing a lumbar puncture, patients experience a headache. In most cases, this symptom occurs due to the ingress of the injected fluid into the tissues that are located nearby. As a rule, the headache occurs in a standing or sitting position, but pain syndrome can also appear when the patient is in a horizontal position. Based on all these adverse reactions, doctors strongly recommend limiting physical activity as much as possible for several days from the date of the operation. During this period, it is advisable to observe bed rest.
Orthopedic mattresses
Another common ailment that can be experienced after a spinal cord puncture is severe and persistent pain in the spine. At first, it manifests itself at the puncture site, but after a certain amount of time, the painful sensations spread to other parts of the body (most often the pain affects the lower extremities).
Features of the puncture of the spine
It should be noted that this procedure does not require special training and is carried out in a hospital setting. All manipulations are performed by a qualified specialist. The patient is initially given a local anesthetic, but the procedure is often done without anesthesia. For convenience, the patient should lie sideways on the bed or sit on a chair. In this case, the back should be bent at the maximum permissible angle, since such a bend creates the necessary gap between the vertebrae, through which the doctor inserts the needle into the spinal canal. Of course, the area of the body to be operated is thoroughly disinfected beforehand.
The needle is inserted slowly and with great care so as not to damage the soft tissue. Thus, it penetrates into the subarachnoid cavity. Once the needle reaches its target, the doctor will see cerebrospinal fluid from the puncture site. As noted earlier, the goals of a lumbar puncture can be different, so the doctor can, after inserting a needle, inject a drug, take a liquid for laboratory analysis, or conduct CSF tests.
After completing all the necessary actions, the needle is also carefully removed from the patient's body, and the puncture site is closed with a cotton swab and fixed with a plaster. The tampon must be sterile to prevent infection.
On a note! After a successful procedure, the patient must lie on his stomach on a hard couch to prevent the development of dislocation of structures. It is recommended to stay in this position for at least 2 hours. Only after the required amount of time does the doctor allow the patient to get up from the couch, but during the rehabilitation period, bed rest must still be observed.
Cerebrospinal fluid for research and diagnostics
Based on the numerous reviews of patients, in terms of pain, a puncture of the spine is practically no different from a conventional injection in the gluteal region. Often, at the time of insertion of the needle, a sharp, but short-term pain is felt, which indicates damage to the nerve endings. In such cases, the doctor should pull back the needle a little and, changing its direction, continue the procedure. Such damage does not lead to serious consequences, so when acute pain appears, you should not panic.
If you want to know in more detail whether it is dangerous to carry out, as well as consider contraindications and types of blockades, you can read an article about this on our portal.
Are there any contraindications?
There are certain contraindications for lumbar puncture, which must be taken into account. For example, it is forbidden to perform the procedure if there is suspicion of stem symptoms or brain dislocation. Also, the puncture is not recommended to be carried out with a decrease in picore pressure. Otherwise, there can be serious consequences. With a decrease in pressure indicators in the spiral volume, the infringement of the brain column occurs, against which the operation can be fatal.
When performing a puncture of the spine, special attention should be paid to the tendency to bleeding and bleeding disorders. It is also not recommended to take blood thinning medications a few days before the operation. The most common drugs in this group include Warfarin, Clopidogrel, Agrenox and others.
The use of some analgesic drugs also needs to be abandoned, for example, Aspirin, Asafen and Naproxen.
Approximate cost of the procedure
It is possible to carry out a puncture of the spine not only in public medical institutions, but also in private ones. In such cases, the difference may be in price, which will depend on various factors, for example, the nature of the procedure, the choice of clinic for its implementation, as well as the complexity of the study and the level of qualification of the doctor. If we talk about clinics in the capital, the cost of a spinal puncture can vary from 3,000 to 5,000 rubles.

A puncture is a medical procedure that is done to diagnose or treat a disease. The procedure consists in piercing tissue, organ, vessels or pathological neoplasm with a trocar or needle in order to collect fluid for laboratory research, which will help to confirm or deny the diagnosis.
What is puncture used for?
Puncture is performed on mammary glands, cartilage, bone tissue, prostate gland, as well as soft tissue neoplasms, lymph nodes, joints, liver, etc. Also in purulent surgery it is widely used puncture that shows existing purulent inflammatory processes. There are a lot of indications for punctures in this area, these include suspicions of the following pathological processes:
... Paraossal phlegmon;An abscess located inside the bone tissue;
Post-injection infiltrate;
Purulent pleurisy;
Purulent paranephritis;
Paraproctitis;
Douglas abscess.
In addition, puncture is simply necessary for the study of the bacteriology of the purulent process. Some medical manipulations are not carried out without this type of research. For example, the introduction of an X-ray contrast agent into the bone, as well as into the bed of the vessel or body cavity. In addition, puncture is performed to introduce not only liquid media, but also gas, which are necessary for contrasting an organ or cells.
In order to qualitatively determine the focus of the pathological process or to determine the topography of organs, sometimes it is simply necessary to conduct puncture. What shows such a procedure? The fact is that thanks to the introduction of a contrast agent during puncture, blood components and its circulation can be examined. This makes it possible to establish the degree of the pathological process and understand the causes of its occurrence. Puncture is an irreplaceable medical procedure. It is used in all areas of medicine.
What are the therapeutic goals of a puncture?
It has been used to treat diseases for a long time and has not lost its relevance today. Puncture is used for medicinal purposes for:
... Administration of pharmacological agents, blood components, blood substitutes;Local anesthesia;
The introduction of pharmacological agents directly into tissues, organs or neoplasms;
Removal of exudate, pus or blood.
How is the puncture performed?
Previously, hair is removed from the area of the puncture. The procedure itself is performed in a clean room on the operating table. Depending on what type of puncture is performed, the patient can be in a supine or sitting position of the body. The skin is lubricated with an alcohol solution. The needle is defatted with ether and injected directly into the lesion to the required depth. To prevent air from entering the inserted cavity or organ, a special rubber adapter is put on the needle. This adapter will prevent fluid from flowing freely onto the needle. Then a syringe is put on the needle and the required punctate is pumped out. In modern medical centers, the study is carried out under the control of ultrasound or CT. After the material is collected, it is placed in a test tube and the needle is removed with a sharp and quick motion. The puncture site must be treated with an alcohol or iodine solution and a sterile bandage must be applied.
What complications can arise?
Puncture is not a major surgical operation, but nevertheless it is a rather serious medical manipulation. Therefore, as after any other intervention in our body, a puncture can cause some complications. These include:
... injury to blood vessels,Thrombosis,
Hematoma,
Lung tissue disorder
Laparocentesis,
Suppuration,
Inflammation,
Thromboembolism.
A high-quality puncture will help to avoid such negative consequences. Our clinic employs only highly qualified doctors with vast experience, who will carry out the procedure without the risk of complications. The clinic is equipped with the latest medical equipment that will help visualize the puncture process and eliminate medical errors.
Lumbar puncture is an important stage in the diagnosis of neurological pathologies and infectious diseases, as well as one of the methods of drug administration and anesthesia.
This procedure is often called a lumbar puncture, a lumbar puncture.
Thanks to computed tomography and magnetic resonance therapy, the number of punctures performed has significantly decreased.
However, they cannot completely replace the capabilities of this procedure.
Lumbar puncture
About puncture technique
There is a puncture technique that is not allowed to be violated and is a gross mistake of the surgeon. Correctly, such an event should be referred to as a puncture of the subarachnoid space or, more simply, a spinal puncture.
CSF is located under the meninges, in the ventricular system. Thus, nerve fibers are nourished, protection of the brain is created.
When a disorder occurs as a result of a disease, the cerebrospinal fluid can increase, causing increased pressure in the skull. If an infectious process joins, then the cellular composition undergoes changes and in case of hemorrhage blood appears.
The lumbar region is pierced not only for medicinal purposes to administer the drug, but also to diagnose or confirm the alleged diagnosis. It is also a popular method of anesthesia for surgery on the peritoneal and pelvic organs.
It is imperative to study the indications and contraindications when solving spinal cord puncture. This clear list should not be ignored or patient safety is compromised. Of course, such an intervention is not prescribed by a doctor for no reason.
Who can get a puncture?
The indications for such manipulation are as follows:
- suspected infection of the brain and its membranes - these are diseases such as syphilis, meningitis, encephalitis and others;
- diagnostic measures for the formation of hemorrhages and the appearance of formations. It is used for informational impotence of CT and MRI;
- the task is to determine the cerebrospinal fluid pressure;
- coma and other disorders of consciousness;
- when it is necessary to inject a drug in the form of cytostatics and antibiotics directly under the lining of the brain;
- X-ray with the introduction of a contrast agent;
- the need to reduce intracranial pressure and remove excess fluid;
- processes in the form of multiple sclerosis, polyneuroradiculoneuritis, systemic lupus erythematosus;
- unreasonable increase in body temperature;
- spinal pain relief.
Absolute indications - tumors, neuroinfections, hemorrhages, hydrocephalus.
Sclerosis, lupus, an incomprehensible increase in temperature - do not oblige to be investigated in this way.
The procedure is necessary in case of an infectious lesion, since it is important not only to diagnose the diagnosis, but also to understand what kind of treatment is required, to determine the sensitivity of microbes to antibiotics.
Puncture is also used to remove excess fluid with high intracranial pressure.
If we talk about therapeutic properties, then in this way it is possible to act directly on the focus of neoplastic growth. This will make it possible to have an active effect on tumor cells without an elephant dose of drugs.
That is, the cerebrospinal fluid performs many functions - it identifies the causative agents of the disease, is the carrier of information about the cellular composition, blood impurities, reveals tumor cells and tells about the pressure of the cerebrospinal fluid.
Important! Be sure to exclude possible pathologies, contraindications and risks before the puncture. Neglecting this can lead to the death of the patient.
When a lumbar puncture cannot be performed
Sometimes carrying out this diagnostic and treatment procedure can cause more harm and may even be life-threatening.
The main contraindications for which the puncture is not performed:
Puncture procedure
How is the preparation for the procedure going
Preparation depends on the indications and nuances during the lumbar puncture. Any invasive procedure requires diagnostic measures, consisting of:
- blood and urine tests;
- diagnostics of blood properties, in particular, clotting indicators;
Important! The doctor must be informed about the medications taken, allergies and pathologies.
Be sure to stop taking all anticoagulants and angiaggregants a week before the planned puncture, so as not to provoke bleeding. It is also not recommended to use anti-inflammatory drugs.
Women should make sure that there is no pregnancy at the time of the puncture before x-rays with contrast. Otherwise, the procedure may negatively affect the fetus.
If the puncture is performed on an outpatient basis
Then the patient himself can come to the study. If he is being treated in a hospital, then he is brought from the department by the medical staff.
When you come and go on your own, consider returning home. After the puncture, dizziness, weakness are possible, it would be good to use the help of someone.
You should not consume food and liquids 12 hours before the procedure.
Puncture can be assigned to children
The indications are similar in adulthood. However, the majority are infections and suspicions of malignant tumors.
Puncture is not performed without parents, especially when the baby is scared. A lot depends on the parents. They are obliged to explain to the child what the procedure is for, inform about the pain, that it is tolerable and soothe.
As a rule, a lumbar puncture does not imply anesthesia. Local pain relievers are used. This is done for better portability of the procedure. But, in the case of an allergy to novocaine, you can completely abandon anesthesia.
During puncture, when there is a risk of cerebral edema, it makes sense to inject furosemide 30 minutes before the needle is inserted.
The very process of taking a puncture
The procedure begins with the patient taking the correct position. There are two options:
- Lying... The person is placed on a hard table on the right side. In this case, the legs are pulled up to the stomach and clasped by the hands.
- Sitting for example on a chair. It is important in this position to bend your back as much as possible. However, this position is used less frequently.
Puncture is performed in adults over the second lumbar vertebra, usually between 3 and 4. In children 4 and 5, to minimize damage to the spinal tissue.
The technique of the procedure is not complicated if the specialist has been trained and, moreover, has experience. Compliance with the rules allows you to avoid dire consequences.
Stages
The puncture procedure consists of several stages:
Preparation
The medical staff prepares the necessary instruments and materials - a sterile needle with a mandrel (a rod to close the lumen of the needle), containers for cerebrospinal fluid, sterile gloves.
The patient takes the necessary position, the medical staff helps to additionally bend the spine and fix the position of the body.
The injection site is lubricated with iodine solution and then several times with alcohol.
The surgeon finds the right place, the iliac crest, and draws an imaginary perpendicular line to the spine. It is the right places that are recognized as the safest due to the absence of spinal cord matter.
Anesthesia stage
They are used at choice - lidocaine, novocaine, procaine, ultracaine. It is introduced first superficially, then deeper.
Introduction
After anesthesia, a needle is inserted into the intended place with a cut upwards at an angle of 90 degrees relative to the skin. Then, with a slight inclination towards the head of the investigated person, the needle is very slowly inserted into the depths.
On the way, the doctor will feel three needle failures:
- skin puncture;
- intervertebral ligaments;
- the sheath of the spinal cord.
After passing through all the dips, the needle has reached the subshell space, which means that the mandrel should be removed.
If the cerebrospinal fluid does not appear, then the needle should penetrate further, but this must be done with extreme caution due to the proximity of the vessels and in order to avoid bleeding.
When the needle is in the canal of the spinal cord, the cerebrospinal fluid pressure is determined by a special device - a manometer. An experienced doctor can determine the indicator visually - up to 60 drops per minute is considered the norm.
The puncture is taken in 2 containers - one sterile in the amount of 2 ml, which is necessary for bacteriological examination and the second for the cerebrospinal fluid, which is examined to determine the level of protein, sugar, cellular composition, etc.
Completion
When the material is taken, the needle is removed, and the puncture site is sealed with a sterile napkin and adhesive tape.
The above technique for performing the procedure is mandatory and does not depend on age and indications. The accuracy of the doctor and the correctness of actions affect the emergence of the risk of complications.
In general, the amount of fluid obtained during the puncture is not more than 120 ml. If the purpose of the procedure is diagnostics, then 3 ml is enough.
If the patient has a special sensitivity to pain, it is recommended to use sedatives in addition to pain relief.
Important! Throughout the procedure, the patient's mobility is not allowed, therefore the help of the medical staff is required. If the puncture is carried out for children, then the parent helps.
Some patients are afraid of a puncture because of the pain. But, in reality, the puncture itself is tolerable and not terrible. Pain appears when the needle passes through the skin. However, when the tissues are soaked with pain medication, the pain subsides and the site becomes numb.
In the case when the needle touches the nerve root, the pain is sharp, as with sciatica. But, this rarely happens and even refers more to complications.
When the cerebrospinal fluid is removed, the patient diagnosed with intracranial hypertension experiences a distinct sense of relief and relief from the headache.
Recovery period
Once the needle is removed, the patient does not stand up, but remains in a supine position for at least 2 hours on the stomach without a pillow. On the contrary, children under 1 year old are placed on their backs, but pillows are placed under the buttocks and legs.
The first hours after the procedure, the doctor observes the patient every 15 minutes with monitoring of the condition, because the cerebrospinal fluid can run out of the hole from the needle up to 6 hours.
As soon as signs of swelling and dislocation of the brain regions appear, help is urgently provided
After the puncture procedure, bed rest must be observed. It is allowed to get up after 2 days at normal rates. If there are unusual changes, then the period may increase up to 14 days.
Headaches may occur due to a decrease in fluid volume and a decrease in pressure. In this case, the appointment of analgesics is prescribed.
Complications
A lumbar puncture is always risky. They increase if the algorithm of actions is violated, there is not enough information about the patient, in case of a serious health condition.
Possible but rare complications are as follows:
If the procedure is carried out in compliance with all the conditions, then the undesirable consequences almost do not appear.
CSF study stage
Cytological analysis is performed immediately on the same day as the lumbar puncture. When bacteriological culture and an assessment of antibiotic sensitivity are required, the process is delayed by 1 week. This is the time for the cells to multiply and to assess the response to the drugs.
The material is collected in 3 test tubes - for general analysis, biochemical and microbiological.
Normal color cerebrospinal fluid is transparent and colorless, without red blood cells. Protein is contained and the indicator should not exceed 330 mg per liter.
There is a small amount of sugar and erythrocytes - in adults, no more than 10 cells per μl, in children, a higher indicator is allowed. The normal density of the cerebrospinal fluid is 1.005 to 1.008, pH is from 7.35-7.8.
If there is blood in the material received, this means that either the vessel is injured, or a hemorrhage has occurred under the lining of the brain. To clarify the reason, 3 test tubes are collected and examined. If the cause is hemorrhage, then the blood will be scarlet.
An important indicator is the density of the cerebrospinal fluid which changes with disease. If there is inflammation, then it increases, if hydrocephalus decreases. If at the same time the pH level has dropped, then most likely the diagnosis is meningitis or encephalitis, if it has increased - brain damage with syphilis, epilepsy.
Dark liquid speaks of jaundice or melanoma metastasis.
Cloudy cerebrospinal fluid is a bad sign of bacterial leukocytosis.
If the protein is increased, then most likely we will talk about inflammation, tumors, hydrocephalus, brain infection.
