The main objective of this article is to present the updated data regarding the perioperative management of patients undergoing major spine surgery in an era where the surgical techniques are changing and there is a high demand for these surgeries in older and high-risk patients. ⋯ A tailored approach to patients undergoing major spine surgeries seems to be effective improving the outcome and quality of life of patients. Future studies should aim to understand which elements of the ERAS can be improved to allow the patient to have a long-term good outcome. VIDEO ABSTRACT.

The aim of this review is to summarize recent relevant literature regarding regional anesthesia in the diabetic neuropathic patient and formulate recommendations for clinical practice. ⋯ The pathophysiologic mechanisms underlying diabetic polyneuropathy are complex. Several pathways are thought to contribute to the development of diabetic neuropathy, triggered most importantly by chronic hyperglycemia. The latter induces inflammation and oxidative stress, causing microvascular changes, local ischemia and decreased axonal conduction velocity. Regional anesthesia is different in patients with diabetic neuropathy in several regards. First, the electric stimulation threshold of the nerve is markedly increased whereby the risk for needle trauma in stimulator-guided nerve blocks is theoretically elevated. Second, the diabetic nerve is more sensitive to local anesthetics, which results in longer block duration. Third, local anesthetics have been conjectured to be more toxic in diabetic neuropathy but the evidence is equivocal and should not be a cause to deny regional anesthesia to patients with a valid indication. Lastly, when peripheral nerve catheters are used, diabetes is an independent predisposing factor for infection.

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.

ReviewOpioid-induced hyperalgesia in clinical anesthesia practice: what has remained from theoretical concepts and experimental studies?
This article reviews the phenomenon of opioid-induced hyperalgesia (OIH) and its implications for clinical anesthesia. The goal of this review is to give an update on perioperative prevention and treatment strategies, based on findings in preclinical and clinical research. ⋯ Since the immediate postoperative period is not ideal to initiate long-term treatment for OIH, the best strategy is to prevent its occurrence. A multimodal approach, including choice of opioid, dose limitations and addition of nonopioid analgesics, is recommended.

ReviewTraining anesthesiologists in out-of-operating room anesthesia.
The purpose of this review is to describe recent developments and current trends in training anesthesiologists in out-of-operating room anesthesia (OORA). ⋯ This review will provide useful models for training directors needing to design and implement OOR rotations for their trainees.
