Lumbar puncture Procedure:

Description

  • Insertion of a spinal needle through the L3–L4 interspace into the lumbar subarachnoid space to obtain CSF; measure CSF fluid or pressure; or instill air, dye, or medications
  • The test is contraindicated in clients with increased intracranial pressure (ICP), because the procedure will cause a rapid decrease in pressure in the CSF around the spinal cord, leading to brain herniation.

Preprocedure interventions: 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.
