Intraoperative changes in somatosensory (SEP) and motor evoked potentials (MEPs) may indicate potential injury to the spinal cord and will require timely intervention to prevent permanent damage. This review focuses on the validity of currently recommended warning criteria for intraoperative evoked potential monitoring. ⋯ Current recommendations for warning criteria during intraoperative evoked potential monitoring are empirically derived. Until a threshold that predicts spinal cord injury can be accurately determined, it remains difficult to define the clinical utility of intraoperative neurophysiologic monitoring.

ReviewRegional blocks carried out during general anesthesia or deep sedation: myths and facts.
More patients will accept regional blocks if these are performed during sedation or general anesthesia. This review discusses regional anesthesia in sedated or anesthetized patients. ⋯ With the use of ultrasound guidance in skilled hands, it is a reasonable option to perform neuraxial and peripheral regional blocks in sedated or anesthetized patients. Performing the procedure safely and effectively requires an adequate level of experience with the specific block technique in question.

Our review of current literature within the past 12-24 months for the treatment of lumbar spinals stenosis (LSS) serves to update providers on recent advances and comparisons regarding therapy spanning lifestyle modification, pharmacologic therapy, minimally invasive interventions, and surgical interventions. ⋯ Our review of current research demonstrates there is a positive role for the current conservative therapies, with favorable results for interventions such as minimally invasive decompression and SCS. Pharmacologic interventions such as systemic prostaglandin analogues and epidural agents such as calcitonin demonstrate early promise, but need to undergo additional safety testing and confirmatory trials. Further long-term research with validated, objective measurements for the aforementioned treatments are needed to draw any definitive conclusions for clinical practice.
