Stroke is a leading cause of death and disability, and is associated with a huge societal and economic burden. Interventions for the immediate treatment of ischaemic stroke due to large vessel occlusion are dependent on recanalisation of the occluded vessel. Trials have provided evidence supporting the efficacy of mechanical thrombectomy in ischaemic stroke due to large vessel occlusion. ⋯ These and other studies have highlighted the importance of optimal blood pressure management as a major determinant of patient outcome. Anaesthetic management should be tailored to the individual patient and circumstances. Acute ischaemic stroke is a neurological emergency; clinicians should focus on minimising door-to-groin puncture time and the provision of high-quality periprocedural care with a particular emphasis on the maintenance of an adequate blood pressure.

Observational Study
Mediastinal Masses, Anesthetic Interventions, and Airway Compression in Adults: A Prospective Observational Study.
Central airway occlusion is a feared complication of general anesthesia in patients with mediastinal masses. Maintenance of spontaneous ventilation and avoiding neuromuscular blockade are recommended to reduce this risk. Physiologic arguments supporting these recommendations are controversial and direct evidence is lacking. The authors hypothesized that, in adult patients with moderate to severe mediastinal mass-mediated tracheobronchial compression, anesthetic interventions including positive pressure ventilation and neuromuscular blockade could be instituted without compromising central airway patency. ⋯ These observations suggest a need to reassess prevailing assumptions regarding positive pressure ventilation and/or paralysis and mediastinal mass-mediated airway collapse, but do not prove that conventional (nonstaged) inductions are safe for such patients.

Surgery and general anaesthesia have the potential to disturb the body's circadian timing system, which may affect postoperative outcomes. Animal studies suggest that anaesthesia could induce diurnal phase shifts, but clinical research is scarce. We hypothesised that surgery and general anaesthesia would result in peri-operative changes in diurnal sleep-wake patterns in patients. ⋯ Disruption started from one night before surgery and did not normalise until 6 days after surgery. We conclude that there is a peri-operative phase advance in midpoint of sleep, confirming our hypothesis that surgery and general anaesthesia disturb the circadian timing system. Patients had decreased subjective sleep quality, worse sleep efficiency and increased daytime fatigue.

Case Reports Comparative Study
Investigation of asleep versus awake motor mapping in resective brain surgery.
To develop an asleep motor mapping paradigm for accurate detection of the corticospinal tract during glioma surgery and compare outcomes with awake patients undergoing glioma resection. ⋯ In this small patient series, asleep motor mapping using commonly available motor evoked potential hardware appears to be safe and efficacious in regard to EOR and functional outcomes.

Introduction: Post-anaesthetic sore throat (PAST) is a well-recognized consequence of tracheal intubation; however, quantitative morphometric measurements remain challenging. This study aimed to introduce a special laser projection device that can facilitate computer-assisted, digitalized analysis and provide important information on laryngeal mucosa change, pre and post-surgery under general anesthesia with intubation. Materials and methods: The laryngeal images were captured and divided into the control group and the intubation group. ⋯ Conclusion: Our equipment and processing can measure subtle laryngeal changes that would allow a clinician to diagnose postoperative laryngeal inflammation in a simpler and less invasive way. The trend toward red, the increased contrast texture and vocal width, and the reduced glottic space were all compatible with post-intubation inflammatory response, especially in the interarytenoid region. This is important to know so that one can take appropriate steps to alleviate PAST in the future.
