ReviewNeuromonitoring and Neurocognitive Outcomes in Cardiac Surgery: A Narrative Review.
Neurocognitive dysfunction after cardiac surgery can present with diverse clinical phenotypes, which include postoperative delirium, postoperative cognitive dysfunction, and stroke, and it presents a significant healthcare burden for both patients and providers. Neurologic monitoring during cardiac surgery includes several modalities assessing cerebral perfusion and oxygenation (near-infrared spectroscopy, transcranial Doppler and jugular venous bulb saturation monitoring) and those that measure cerebral function (processed and unprocessed electroencephalogram), reflecting an absence of a single, definitive neuromonitor. This narrative review briefly describes the technologic basis of these neuromonitoring modalities, before exploring their use in clinical practice, both as tools to predict neurocognitive dysfunction, and with a bundle of interventions designed to optimize cerebral oxygen supply, with the aim of reducing postoperative delirium and cognitive dysfunction following cardiac surgery.

Meta AnalysisThe Use of Cerebral Oximetry in Surgery: A Systematic Review and Meta-analysis of Randomized Controlled Trials.
The evidence on the use of cerebral oximetry during surgery to minimize postoperative neurologic complications remains uncertain in the literature. The present authors aimed to assess the value of cerebral oximetry in the prevention of postoperative cognitive dysfunction, postoperative delirium, and postoperative stroke in adults undergoing surgery. ⋯ Adult patients with cerebral oximetry monitoring were associated with a significant reduction of postoperative cognitive dysfunction. However, given the low certainty of evidence and substantial heterogeneity, more randomized controlled trials using standardized assessment tools for postoperative cognitive dysfunction and interventions of correcting cerebral desaturation are warranted to improve the certainty of evidence and homogeneity.

Meta AnalysisRole of Hypothermia in Adult Cardiac Surgery Patients: A Systematic Review and Meta-analysis.
To review studies that assessed systemic hypothermia as an organ protection strategy in adults undergoing cardiac surgery with cardiopulmonary bypass. ⋯ The existing evidence for an organ-protective effect of hypothermia in adult cardiac surgery is of low quality and inconsistent.

ReviewPerioperative Presentations of Kounis Syndrome: A Systematic Literature Review.
Kounis syndrome commonly is described as a complex multisystem phenomenon mainly affecting coronary arteries, resulting in coronary vasospasm in the context of an allergic manifestation. This article reviews the literature regarding perioperative presentations of the syndrome. A systematic search in MEDLINE and Embase databases was performed for case reports through June 16, 2021, on Kounis syndrome triggered by medications administered in the perioperative setting. ⋯ Coronary vasospasm is often less frequently recognized as a form of allergic manifestation in the perioperative setting. Many potential triggers, such as antibiotics and neuromuscular blocking agents, are routinely administered during surgery. Awareness of this condition, early diagnosis, and effective management of this condition can lead to good outcomes.

ReviewAnesthetic Considerations for Percutaneous Coronary Intervention for Chronic Total Occlusions-A Narrative Review.
Advancing stent technology has enabled interventional cardiologists to perform percutaneous coronary intervention (PCI) to open chronic total occlusions (CTOs). Because PCI for CTOs improve patient anginal symptoms and quality of life, these procedures have been increasing over the past decade. Compared to standard PCI, these procedures are technically more difficult, with prolonged procedure time and increased risk of complications. ⋯ Understanding the procedural techniques of these complex PCI procedures is important to enable optimal anesthetic care in these patients. This narrative review discusses the pathophysiology, risks, benefits, procedural steps, and main anesthetic considerations for patients undergoing CTO PCI. Despite a growing body of literature, future research is still required to elucidate optimal anesthetic and mechanical support strategies in patients undergoing CTO PCI.
