Observational StudyRegional Anaesthesia Alone is Reasonable for Major Lower Extremity Amputation in High Risk Patients and May Initiate a More Efficacious Enhanced Recovery Programme.
Major limb amputations are physiologically stressful and subject patients to peri-operative cardiovascular risk. Up to 90% of major lower extremity amputations (LEAMP) are being performed under general anaesthesia, despite regional anaesthesia being an acceptable option in most cases. Obtaining a better understanding of who would benefit from regional vs. general anaesthesia could reduce complications and help establish best evidence based practice. It was hypothesised that patients undergoing LEAMP with regional anaesthesia would have better post-operative outcomes than patients receiving general anaesthesia. ⋯ There was no difference in outcomes between regional or general anaesthesia techniques in patients undergoing LEAMP, despite the regional group having more comorbidities. Regional anaesthesia may be under used for high risk patients undergoing LEAMP. Further studies are needed to establish best practices in LEAMP procedures.

Observational Study
Effect of anesthesia strategy during endovascular therapy on 90-day outcomes in acute basilar artery occlusion: a retrospective observational study.
The research on the effect of anesthesia on endovascular therapy (EVT) of acute ischemic stroke is mainly focused on the anterior circulation, and little is known about the data of basilar artery occlusion (BAO). This study aims to investigate the association of anesthesia strategy with 90-day clinical outcomes of patients with acute BAO treated with EVT. ⋯ Our retrospective analysis suggested that the anesthesia strategy may affect outcome, in which general anesthesia may result in less favorable outcomes. Nevertheless, future multicenter randomized controlled trials are needed to confirm our findings.

The beach chair position that is commonly used in shoulder surgery is associated with relative hypovolemia, which leads to a reduction in arterial blood pressure. The effects of patient positioning on the accuracy of non-invasive continuous blood pressure monitoring with the ClearSight™ system (CS-BP; Edwards Lifesciences, Irvine CA, USA) have not been studied extensively. Our research aim was to assess agreement levels between CS-BP measurements with traditional blood pressure monitoring techniques. ⋯ We found clinically acceptable mean differences in MAP measurements between the ClearSight™ and non-invasive oscillometric blood pressure systems when patients were in either the supine or beach chair position. For all comparisons of the monitoring systems and surgical positions, the standard deviations and limits of agreement were wide.

The persistent loss of consciousness caused by general anesthesia without the existence of repeated 90-minute cycles of non-REM and REM sleep might significantly disturb and suppress the cycle of normal physiological sleep in postoperative periods after general anesthesia. Patients with autism spectrum disorders (ASD) with existing circadian rhythm disorder are reported to rapidly deteriorate due to acute sleep disorder during the perioperative period after general anesthesia.A melatonin receptor agonist, ramelteon (Rozerem), which is a sleep cycle regulator, is used as a therapeutic drug for patients with sleep disorders, but there are no studies on the prevention of postoperative sleep disorder after general anesthesia.In this study, we investigate whether prophylactic administration of a sleep-inducing substance, a melatonin receptor agonist, is effective against sleep disorder after general anesthesia in patients with ASD. ⋯ Postoperative sleep disorders after general anesthesia has been reported in patients with ASD; however, effective preventive pharmacological treatments have not been established. A sleep cycle regulator, ramelteon (Rozerem), is used as a therapeutic drug for patients with sleep disorders by decreasing the difficulty of falling asleep in insomnia. If sleep disorder can be prevented after the administration of general anesthesia in patients with ASD, we can support social participation while maintaining their quality of life.
