Lumbar Drain

Watch for:

  • respiratory depression

  • change in level of consciousness

  • motor / sensory changes

  • vital sign changes

  • bowel / bladder dysfunction

  • overdrainage can cause headache / SDH

The rationale for the use of CSF drainage is based on animal evidence that suggests that decreasing CSF pressure to less than 10 mm Hg during clamping of the thoracic aorta enhances perfusion of the spinal cord and decreases the risk for ischemic injury (6,15-17). While CSF drainage appears to be a promising intervention to reduce the incidence of paraplegia, there exists uncertainty as to the effectiveness of this intervention in human beings.

The cerebrospinal fluid (CSF) pressure increases during clamping further decreasing the perfusion pressure of the spinal cord.

 Draining CSF from the lumbar region may lessen the CSF pressure, improve blood flow to the spinal cord and reduce the risk of ischaemic spinal cord injury.

... but I would more especially commend the clinician who, in acute diseases, by which the bulk of mankind are cutoff, conducts the treatment better than others.
