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.

ReviewThe Year in Extracorporeal Membrane Oxygenation: Selected Highlights From 2021.
This review summarizes the extracorporeal membrane oxygenation (ECMO) or extracorporeal life support literature published in 2021. This Selected Highlights article is not intended to be an exhaustive review of the literature, but rather a summarizing of key themes that developed in the ECMO literature during 2021. The primary topics presented include the following: ECMO for coronavirus disease 2019, extracorporeal cardiopulmonary resuscitation, periprocedural cardiopulmonary support with ECMO, and anticoagulation for ECMO.

ReviewContrast-Enhanced Echocardiography Application in Patients Supported by Extracorporeal Membrane Oxygenation (ECMO): A Narrative Review.
Extracorporeal membrane oxygenation (ECMO) is a lifesaving intervention increasingly used to support patients with severe respiratory and cardiac dysfunction. Echocardiography is an important tool, aiding implantation and monitoring during ECMO therapy, but often its use is limited by poor acoustic windows. ⋯ In this article the authors review the literature addressing the use of contrast-enhanced echocardiography (CEE) in ECMO-supported patients. The authors discuss the role of CEE in guiding implantation of ECMO, cardiac assessment and diagnosis of complications during ECMO therapy, as well as the safety of ultrasound-enhancing agents in this cohort of patients.

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.
