Intrathecal Placement of Lumbar Drain: A Technique to Withdraw Cerebrospinal Fluid from the Lumbar Spine in Porcine Model

Abstract

This video describes the technique of intrathecal placement of a lumbar drain in a porcine ischemic model, which helps in draining the cerebrospinal fluid to a drainage system. The cerebrospinal fluid pressure is monitored by the drainage system, and fluid is drained to maintain a constant cerebrospinal fluid pressure.

Protocol

All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. The study was performed in six three-month-old male and female pigs (German Landrace) weighing approximately 40 kg. Animals were brought to the animal care facilities at least 7 days prior to the experiments and were housed in accordance to animal welfare recommendations. Animals were provided food and water ad libitum, and their health status was reg…
