Watch a technique, how to give spinal injection.
• Insertion of a spinal needle through the L3-L4 interspace into the lumbar subarachnoid space to obtain cerebrospinal fluid (CSF), measure CSF fluid or pressure, or instill air, dye, or medications
• The test is contraindicated in clients with increased intracranial pressure because the procedure will cause a rapid decrease in pressure in the CSF around the spinal cord, leading to brain herniation.
- Obtain an informed consent.
- Have the client empty the bladder.
Interventions during the procedure
- Position the client in a lateral recumbent position and have the client draw the knees up to the abdomen and the chin onto the chest; the prone position may be required for radiologically guided punctures.
- Assist with the collection of specimens (label the specimens in sequence).
- Maintain strict asepsis.
- Monitor vital signs and neurological signs to check for the presence of leakage of cerebrospinal fluid.
- Position the client flat as prescribed.
