Spinal catheter insertion via seated lumbar puncture using a massage chair.

Abstract

Spinal catheter insertion may be used for the diagnosis of adult hydrocephalus.1,2⇓ The procedure requires lumbar puncture (LP) in the lateral decubitus or seated positions.3-5⇓⇓ Because adult hydrocephalus predominantly affects persons 60 to 90 years old, LP in the lateral decubitus position can be difficult because it is hard for patients to maintain proper position.3 LP with patients in the seated position are often difficult because of the lack of a stable, safe platform for the patient. A common technique, although apparently undocumented in peer-reviewed literature, is to have the patient sit on the edge of the bed while leaning on an over-bed table with a pillow on it. Although this approach may improve flexion of the lumbosacral spine, it carries the risk that the wheeled over-bed table can move forward, potentially causing the patient to fall, or sideways, potentially misaligning the spine. This technique requires the assistance of additional persons to maintain the patient’s position, prevent …
