Your question: Is there an alternative to a spinal tap?

As an alternative to lumbar puncture for acquisition of cerebrospinal fluid, lateral cervical puncture is simple to perform and appears to have less potential for major complications than suboccipital puncture.

Can you refuse a spinal tap?

If you decide to go ahead, you will be asked to sign a consent form. This states that you agree to have the procedure and associated treatment, and you understand what it involves. You can at any time refuse to have the LP done for any reason. However, the doctor will need to discuss the implications of this with you.

Can you be sedated for lumbar puncture?

This examination is usually done on an outpatient basis. A nurse or technologist will insert an intravenous (IV) line into a vein in your hand or arm to administer a sedative. This procedure may use moderate sedation. It does not require a breathing tube.

When should you avoid a spinal tap?

Avoid lumbar puncture in patients in whom the disease process has progressed to the neurologic findings associated with impending cerebral herniation (ie, deteriorating level of consciousness and brainstem signs that include pupillary changes, posturing, irregular respirations, and very recent seizure)

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 diseases can be found in spinal fluid?

Diseases detected by CSF analysis

  • meningitis.
  • encephalitis.
  • tuberculosis.
  • fungal infections.
  • West Nile virus.
  • eastern equine encephalitis virus (EEEV)

Can you say no to a lumbar puncture?

Lumbar puncture (LP) is an effective method in the diagnosis and management of central nervous system infections. Refusal to LP is associated with severe consequences.

What is a lateral cervical puncture?

Lateral cervical puncture involves the placement of a spinal needle into the C1-C2 interspace, posterior and inferior to the vertebral artery. The vertebral artery ascends through the foramina in the transverse processes of the cervical vertebrae beginning at the sixth cervical vertebra.

Why is lumbar puncture so painful?

There are lots of nerves within the fluid in the spinal canal but usually they have room to move out of the way. If one of the nerves is touched, it can give a nasty ache or pain, usually in a leg. Once the needle is in the right place, it takes a few seconds to get the sample.

Can adults be sedated for a spinal tap?

Although pediatric sedation may be used to achieve urine catheterization or to obtain intravenous (IV) access, in adults, sedation is not typically used for such minor procedures. For example, minimal sedation may be used in adults for a lumbar puncture or for an ankle arthrocentesis.

What should you not do before a lumbar puncture?

However, on the day of the procedure, do not eat for three hours before the procedure. You may have liquids and can take your usual medications unless previously advised to hold certain medications in preparation for the lumbar puncture.

Is a spinal tap the same as an epidural?

Back to epidurals and spinals: The main difference is the placement. With an epidural, anesthesia is injected into the epidural space. With a spinal, the anesthesia is injected into the dural sac that contains cerebrospinal fluid. The direct access means that a spinal gives immediate relief.

What drugs can be detected in a spinal tap?

Classes of drugs evaluated in this study included: benzodiazepines, anticonvulsants, sedatives, opioids, antidepressants, anesthetics, and antihistamines. The majority of the drugs tested were readily detected in CSF specimens. The average CSF/blood ratio for most drugs was in the range of 0.05-0.50.
