Neuraxial Blockade in Patients with Preexisting Spinal Stenosis, Lumbar Disk Disease, or Prior Spine Surgery: Efficacy and Neurologic Complications
Patients with spinal canal pathology,
including spinal stenosis and lumbar disk disease, are often not
considered candidates
for neuraxial blockade because of the risk of
exacerbating preexisting neurologic deficits or developing new
neurologic dysfunction.
In contrast, a history of spine surgery is
thought to increase the likelihood of difficult or unsuccessful block.
In this
retrospective study we investigated the risk of
neurologic complications and block efficacy in patients with preexisting
spinal
canal pathology, with or without a history of
spine surgery, after neuraxial anesthesia.
