Watch a technique, how to give spinal injection.
Lumbar puncture
Description
• 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.
Preprocedure interventions
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.
Postprocedure interventions
Monitor vital signs and neurological signs to check for the presence of leakage of cerebrospinal fluid.
Position the client flat as prescribed.
