5. Take care to use devices of suitable dimensions (diameter, length), espe-
cially when treating obese patients and children.
6. With regard to the usage and disposal of the product, apply general pre-
cautions for handling blood and body fluids as a routine measure due to
the hazard of coming into contact with pathogens transferred by blood.
Sequence of use
1. Position patient either in a curled lateral decubitus position or seated, lean-
ing over a suitable support.
2. Select preferred needle size and manometer.
3. Place the spinal cannula.
4. Remove the needle stylet. CSF flow confirms placement into the dural-
space. Attach the 3-way stopcock and manometer to the needle. Rotate the
stopcock to vent the needle to the manometer whilst closing the proximal
port.
5. Allow CSF to flow into the manometer tube, when the fluid level has sta-
bilised, read the value from the manometer column in cmH
CSF pressure is in the range 18–24 cmH
Pressure readings are less reliable if the patient is in the sitting position.
6. Close the stopcock to the needle and drain the fluid from the manometer
tube into the collection tubes for subsequent analysis.
7. If the scale of the spinal manometer with a maximum of 35 cmH
sufficient to measure CSF pressure, an extension to 54 cmH
Attach this to the riser pipe of the manometer.
8. When sufficient sampling has been completed, remove spinal needle,
manometer and introducer needle if used and apply the dressing to the
puncture site.
9. Instruct the patient to remain Iying down for 1–2 hours before getting up.
Lumbar puncture may cause dizziness, profound headache and can disturb
balance.
