Intrathecal Placement of Lumbar Drain: A Technique to Withdraw Cerebrospinal Fluid from the Lumbar Spine in Porcine Model
Trascrizione
For percutaneous placement of cerebrospinal fluid drainage for measuring and controlling cerebrospinal pressure, identify the level of Lumbar 4 / 5, or L 5 / 6. Puncture the skin, and the subcutaneous space with the introducer needle, and remove the inlay needle. Place a saline-filled syringe onto the introducer needle, and use constant pressure to carefully introduce the needle into the epidural space.
Once a loss of resistance is felt, indicating a correct epidural placement, insert the inlay needle and advance the needle 2 to 3 millimeters into the intrathecal space. Introduce the drainage up to a 20-centimeter depth. Attach a Luer-lock adapter, and verify the position by careful aspiration of the liquor. Then, carefully fix the drainage with sutures, and connect the drainage to the cerebrospinal fluid drainage system.
