Your Lumbar Puncture Journey

Understanding Lumbar Puncture

A Lumbar Puncture is a medical procedure where a needle is carefully inserted into the lower part of your spine (the lumbar region) to collect a small amount of cerebrospinal fluid (CSF). CSF is the clear fluid that surrounds your brain and spinal cord, protecting and nourishing them.

Preparing for Your Lumbar Puncture

Before the Procedure :To help ensure your safety:

• 1

  You may be asked to stop certain medications, especially blood thinners, several days before the Test.

• 2

  You will usually be advised not to eat or drink for a few hours before the procedure, but your doctor will give specific instructions.

• 3

  Inform your doctor if you have allergies, infections, or bleeding disorders.

• 4

  Let your healthcare team know if you feel anxious or have difficulty lying still.

The Day of the Procedure

You are advised to bring:

• 1

  Comfortable clothing that can be easily removed or adjusted

• 2

  A list of all medications and allergies

• 3

  Government-issued ID

• 4

  Health insurance information.

• 5

  Leave valuables and jewellery at home.

• 6

  If you are going to be sedated, ensure someone accompanies you home.

The Procedure

• You will lie on your side with your knees drawn up towards your chest or sit leaning forward, to open up the space between your vertebrae.
• The nurse or doctor will clean your lower back with antiseptic and cover the area with sterile drapes.
• A local anaesthetic will be injected to numb the area. This may sting briefly.

STEP 1: Getting Ready

• The doctor will insert a thin needle between two lumbar vertebrae to access the CSF.
• You may feel some pressure or discomfort but no sharp pain.
• A small amount of fluid will be collected into sterile tubes for testing.
• The needle will be removed and a small dressing applied to the puncture site.

STEP 2: The Lumbar Puncture

• You will rest lying flat for about 30 to 60 minutes to reduce the chance of headaches.
• Your vital signs will be monitored for any immediate reactions.

STEP 3: After the Procedure

Aftercare and Recovery

• You may feel tired or experience mild discomfort in your lower back.
• Headaches are common but usually mild and short-lived. Drinking plenty of fluids helps.

At the Hospital

• Rest for the remainder of the day, avoiding strenuous activity.
• Keep the puncture site clean and dry for 24 hours.
• You can shower after 24 hours but avoid baths or swimming until the site is healed.
• Take any painkillers as advised by your doctor.

At Home

Possible Complications
