In addition to epidural bleeding, vigilance is required to diagnose infections of the spinal structures. Twelve (27%) patients had undergone explanation due to treatment failure at an average of 18 months after implantation. A January 2020 study in the journal Regional Anesthesia & Pain Medicine (8) discusses these patients problems: The researchers noted that spinal cord stimulators are generally offered to patients first and then when they fail, targeted drug delivery devices are then recommended. This electrical current helps to disrupt pain signals to your brain and replaces them with a mild buzzing sensation. Prior to moving forward with a permanent implant, the patient should have a trial that provides significant relief. In summary, the researchers write: among all patients, spinal cord stimulation for post-laminectomy syndrome resulted in statistically significant reductions in the number of opioid prescriptions in some comparisons, but the reduction was small and its clinical relevance is questionable.
