Lumbar Puncture - Equipment

This page will introduce you to the equipment you will need for Lumbar Puncture. You can either scroll down the page or click on an item to see a description of it. Once you've reviewed the equipement, move onto the steps of the procedure as outlined on the left menu bar.



Sponge Sticks

This is your sponge. It is used to apply cleaning solution to your patient's back in order to create a sterile field.


White Sheet

The white drape is used to create a sterile field along the bottom of your patient and along the stretcher. Place it under your patient's hip carefully while maintaining sterile technique. See the video for this step.


Blue Sheet

The blue drape is used to create a sterile field to work in. On the back of the drape is a section of adhesive material. Peel the white cover off of it and use the adhesive to secure the drape to your patient's back.



The bandage is applied to the LP site after the LP Needle is finally removed.


Anesthesia Needle

The syringe and the attached 25g needle are used to provide local anesthesia to the skin. Some LP trays have local anesthetics supplied with it. 1% lidocaine without epinephrine is the usual choice for local anesthesia. Many practioners choose to use a larger syringe and deliver more local anesthetic.


22 Gauge Needle

The 22 gauge needle is used to deliver local anesthetic to the deeper structures of your patient's back.


Test Tubes

The test tubes are used to collect your sample of cerebrospinal fluid. Note the tubes are numbered one through four and the samples should be collected in order. You should collect about 1/2 mL of CSF per tube.



The stopcock is used to connect your manometer tubing to the manometer. Using the 3 way valve you can measure your patient's opening pressure and then collect your CSF sample.


LP Needle

This is the lumbar puncture needle supplied on the tray. The bottom picture shows it with the stylette partly removed. This needle is quite large (22g) and has a Quinke cutting tip. It can be substitutued for a smaller blunt tipped needle if desired.


Manometer Tubing

Manometer tubing is used in measuring your patient's opening pressure. You can connect the tubing to the LP needle on one end and to the stopcock and manometer on the other. This is demonstrated in the upcoming video,




The manometer is used to measure your patient's opening pressure. The manometer is attached to the stopcock and then to the manometer tubing. This in turn is attached to the LP needle. This is demonstrated in the upcoming video.
