Anesthesia for cardiac surgery has traditionally utilized high-dose opioids to blunt the sympathetic response to surgery. However, recent data suggest that opioids prolong postoperative intubation, leading to increased morbidity. Given the increased risk of opioid dependency after in-hospital exposure to opioids, coupled with an increase in morbidity, regional techniques offer an adjunct for perioperative analgesia. The aim of this review is to describe conventional and emerging regional techniques for cardiac surgery. ⋯ New regional techniques for cardiac surgery may be potent perioperative analgesic adjuncts, but well-designed studies are needed to quantify the effectiveness and safety of these blocks.

ReviewThe impact of frailty and sarcopenia on patient outcomes after complex spine surgery.
Frailty and sarcopenia represent a state of increased fragility and decreased reserve, and both have been associated with worse outcomes after surgery. The present review focuses on the definitions and measurement tools used to assess frailty and sarcopenia in patients with spinal disorder, and the relationships between frailty, sarcopenia, and postoperative outcomes in patients undergoing complex spine surgery. ⋯ Frailty and sarcopenia are increasingly recognized as important predictors of adverse outcomes after complex spine surgery. The optimal tool to measure frailty and sarcopenia in patients with spinal disorders remains unclear, and the role of surgery as an intervention to reverse frailty requires further investigation.

ReviewAnaesthesia for stroke thrombectomy: technical considerations based on outcome evidence.
Stroke is the second leading cause of death and the third leading cause of disability worldwide. Treatment is time limited and delays cost lives. This review discusses modern stroke management, during a time when treatments and guidelines are rapidly evolving. ⋯ An individualized approach to the patient's anaesthetic management is optimal, and depends on close communication with the neurointerventionalist regarding patient and procedure-specific variables. No specific anaesthetic agent is preferred. Guiding principles are minimization of time delay, and maintenance of cerebral perfusion pressure.

ReviewNeurological complications after cardiac surgery: anesthetic considerations based on outcome evidence.
Neurological complications after cardiac surgery remain prevalent. This review aims to discuss the modifiable and outcome-relevant risk factors based on an up-to-date literature review, with a focus on interventions that may improve outcomes. ⋯ The available evidence highlights the importance of maintaining optimal and individualized blood pressure, cerebral tissue oxygen saturation and hemoglobin level in improving neurological outcomes after cardiac surgery. However, outstanding issues remain and need to be addressed via outcome-oriented further research.

ReviewRegional anesthesia and pain management in patients with sleep apnea: can they improve outcomes?
In several guidelines, regional anesthesia and analgesia have been suggested as safer alternatives for general anesthesia and systemic analgesia for their safety profile in patients suffering from obstructive sleep apnea (OSA). However, the underlying scientific basis is still evolving. The present review is intended to provide an up-to-date account on the question whether the use of regional anesthesia improves outcomes in patients with OSA. ⋯ Regional anesthesia can be recommended as a good strategy to treat patients with OSA whenever feasible, as it reduces the incidence of potentially catastrophic perioperative complications. However, the breadth of both surgical and regional anesthetic techniques analyzed is limited; further research should focus on extending the knowledge base beyond neuraxial anesthesia and orthopedics.
