The failure of CSF flow before spinal drug administration (often known as a dry tap), is usually caused by
a needle blockage
, a needle in the wrong space, previous spinal surgery, or low CSF pressures [8, 9].
What is the most common complication of lumbar puncture?
Headache
is the most common complication of lumbar puncture, observed in 20-70% of patients. It usually begins 24-48 hours after the procedure and is more common in young adults. The probable etiology is continued leakage of CSF from the puncture site.

What is a normal finding for the spinal fluid of a lumbar puncture?
Normal lumbar puncture (LP) cerebrospinal fluid (CSF) findings include the following: Appearance:
Clear
.
Opening pressure: 10-20 cm H
2
O
.
WBC count: 0-5 cells/μL
(< 2 polymorphonucleocytes [PMN]); normal cell counts do not rule out meningitis or any other pathology.
What happens if a lumbar puncture goes wrong?
What are possible risks, complications, or side effects of a lumbar puncture? When spinal fluid is removed during an LP, the risks include
headache from a persistent spinal fluid leak, brain herniation, bleeding, and infection
.
When should you go to the ER after a lumbar puncture?
See your healthcare provider or return to the emergency room if you
get redness, drainage, or severe pain around the puncture site
. If you currently have fever or headache, they should resolve within 2-3 days.
Can you become paralyzed from a lumbar puncture?
There is no risk of paralysis
. LPs are typically performed using a special needle designed for this procedure. LP needles have improved over time, and are now smaller, cause less pain at the site where the needle goes in, and are less likely to cause headache after the LP.
What diseases can be found in spinal fluid?
- meningitis.
- encephalitis.
- tuberculosis.
- fungal infections.
- West Nile virus.
- eastern equine encephalitis virus (EEEV)
How long does it take for results of a lumbar puncture?
The doctor or nurse who performs the lumbar puncture can often tell you some of the results straight away and explain what they mean. You may need to
wait for at least 48 hours
for the full results. Some laboratory test results are available within a couple of hours in an emergency.
Can lumbar puncture cause long term back pain?
You may
experience some back pain after
the procedure from where the local anaesthetic injection and lumbar puncture needle was inserted, and may also have some bruising. If you have any back pain after the lumbar puncture you can treat this with pain relief medication such as paracetamol.
What does high glucose in spinal fluid mean?
Abnormal results include higher and lower glucose levels. Abnormal results may be due to: Infection (bacterial or fungus)
Inflammation
of the central nervous system. Tumor.
What do lumbar punctures test for?
During a spinal tap (lumbar puncture), a healthcare provider withdraws cerebrospinal fluid. This test can detect
meningitis, leukemia and other illness
. Providers also use spinal taps to give spinal anesthesia (epidural) and medications.
How long does it take to replenish spinal fluid after a spinal tap?
The CSF is continually produced, and all of it is replaced every
six to eight hours
.
Can a lumbar puncture detect Alzheimer’s?
Alzheimer’s disease is characterised by the abnormal clumps of proteins called amyloid and tau in the brain. These changes are reflected in the levels of proteins in the cerebrospinal fluid, so a
lumbar puncture can indicate whether the brain is affected by Alzheimer’s
disease.
Does a Spinal Tap hurt more than an epidural?
Predicted pain for epidural and spinal insertion (epidural 60.6 +/- 20.5 mm, spinal: 55.1 +/- 24 mm)
was significantly higher than the pain perceived
(epidural 36.3 +/- 20 mm, spinal 46.1 +/- 23.2 mm) (epidural P < 0.001, spinal P = 0.031).
What is post-lumbar puncture syndrome?
Post-lumbar puncture syndrome (PLPS) is
a frequent and important complication of diagnostic lumbar puncture
. PLPS is primarily caused by perforation of the dura mater, leading to persistent leak of the cerebrospinal fluid, and, as a result, intracranial hypotension.
