Lumbar puncture

Training
An LP simulator can be produced with a 3D printed spinal column, latex tubing (for the spinal canal), and a ballistic gel block covered in duct tape. This can be used for ultrasound-guided LP training as well.

Apixaban
This drug may have residual effects after being held for several days. It is probably useful to check anti-Xa levels prior to attempting a lumbar puncture even after apixaban is held.

Complications

 * Headache
 * Intracranial hypotension
 * Retroperitoneal hematoma

Pregnancy
Post-LP headache after neuraxial anesthesia is associated with a much higher incidence of subdural hematoma (adjusted absolue risk increase of 130 (95% CI 90-169).
