After the collection, the patient must remain in the supine position for a few hours (usually 2 or 3 hours are sufficient) for monitoring the clinical conditions.

How is the CSF test done?

The sample is obtained through a procedure called lumbar puncture ("rachicentesis") which involves inserting a long, thin hollow needle between two vertebrae in the lower (lumbar) part of the spine, into the space where the CSF circulates. A few cc of liquid are extracted.

Why is rachicentesis done?

Lumbar puncture is used to: Assess intracranial pressure and cerebrospinal fluid composition (see table Cerebrospinal Fluid Abnormalities in Various Disorders. More information)

Procedures in Emergency Medicine: RACHICENTESI

How much rest after rachicentesis?

The overall duration of the exam is about 30 minutes (the CSF sampling phase is a few minutes), after which the subject must remain prone for at least an hour, recommending bed rest for the next 24 hours. .

How painful is rachicentesis?

The examination is not particularly painful; the sensation is similar to that of an intramuscular puncture. Once the sample is finished, the doctor removes the needle and tampons the point where the puncture was made. The amount of liquor withdrawn varies from 1 to 4 tubes according to the laboratory analyzes to be done.

How long does a headache last after spinal cord injury?

HEADACHE represents one of the most common problems in the immediate post-rachicentesis. It is estimated that over 40% of patients develop headaches shortly after the procedure is finished; the headache may last for a few hours or continue for 2-8 days.

How is rachicentesis performed?

Spinal cordisis is a surgical technique that involves inserting a thin needle (usually 22 G, 75mm long) into the space between the arachnoid menynx and the pia mater (subarachnoid space that contains the cerebrospinal fluid produced by the chorioid plexuses located in the cerebral ventricles) .

How is multiple sclerosis diagnosed?

There is no pathognomonic symptom or sign for multiple sclerosis, nor is there a 100% accurate diagnostic test; the diagnosis is the result of the convergence of clinical, instrumental and laboratory elements. The most important instrumental examination currently for the diagnosis of multiple sclerosis is magnetic resonance imaging.

How painful is lumbar puncture?

Who produces the cerebrospinal fluid?

The CSF is produced inside the cerebral ventricles, precisely at the level of the chorioid plexuses (formed by specialized ependymal cells). Circulating along the brain ventricles, the CSF reaches the sub-arachnoid space, the area between the pia mater and the arachnoid of the brain and spinal cord.

Where is the cerebrospinal fluid found?

The CSF, also called cerebrospinal or cerebrospinal fluid, is the clear and colorless fluid that occupies the cerebral ventricles, the subarachnoid spaces of the meninges and the dural sac of the spinal cord.

How is the spinal cord removed?

The collection takes place in an authorized center, under general anesthesia (deep sedation) or epidural and takes about 45-60 minutes. The marrow is taken directly from the pelvic bones (posterior iliac crests) with the help of a syringe fitted with a needle.

What is the bone marrow examination used for?

In oncology, bone marrow biopsy is performed to diagnose tumors of the blood, of the bone marrow itself or to evaluate the infiltration of tumor cells into the marrow.

What is hydrocephalus?

Hydrocephalus literally means "water in the head". Hydrocephalus is characterized by an increase in the volume of the cerebral ventricles as a consequence of either a reduction in brain mass or excessive production of CSF.

How to recognize liquor by the nose?

(a) Liquid leaking from the nose, collected on absorbent material such as clothing, sheets, gauze, forms a halo in the presence of liquor and blood. The blood, darker in color, is arranged around a much lighter center represented by the liquor [sign of the halo].

Where is the spinal cord located?

Proceeding from top to bottom, the spinal cord begins from an area called the foramen magnum (or foramen magnum) and ends at the level of the second lumbar vertebra (although it has some extensions that reach the sacro-coccygeal region).

Where is the spine done?

Spinal anesthesia is practiced by injecting small doses of anesthetic drugs through a special needle, very long and thin, which is introduced into the back between two vertebrae. The needle reaches the subarachnoid space, where the cerebrospinal fluid (CSF) that bathes the spinal cord and its nerves is found.

What is the lumbar?
