Devices for assessing microcirculation at the bedside have been a technological breakthrough in the critical care field. Thanks to this technology, a large body of scientific evidence has highlighted the relevance of microcirculatory disruptions during critical illness. The goal of this review is to analyze the current knowledge concerning microcirculation monitoring, mainly focused on clinically available devices. ⋯ Currently, there are several methods for microcirculatory monitoring. To properly apply and correctly interpret the information they provide, clinicians should know the fundamental principles and the strengths and weaknesses of the clinically available devices.

ReviewUrine Electrolytes in the Intensive Care Unit: From Pathophysiology to Clinical Practice.
Assessment of urine concentrations of sodium, chloride, and potassium is a widely available, rapid, and low-cost diagnostic option for the management of critically ill patients. Urine electrolytes have long been suggested in the diagnostic workup of hypovolemia, kidney injury, and acid-base and electrolyte disturbances. ⋯ To clarify their potential role in managing critical patients, we reviewed existing evidence on the use of urine electrolytes for diagnostic and therapeutic evaluation and assessment in critical illness. This review will describe the normal physiology of water and electrolyte excretion, summarize the use of urine electrolytes in hypovolemia, acute kidney injury, acid-base, and electrolyte disorders, and suggest some practical flowcharts for the potential use of urine electrolytes in daily critical care practice.

Human decision making involves the deliberate formulation of hypotheses and plans as well as the use of subconscious means of judging probability, likely outcome, and proper action. ⋯ This article provides an overview of known cognitive strategies, as well as a synthesis of their use in critical care. By understanding the ways by which humans formulate diagnoses and make critical decisions, we may be able to minimize errors in our own judgments as well as build training activities around known strengths and limitations of cognition.

In December 2019, a cluster of atypical pneumonia cases were reported in Wuhan, China, and a novel coronavirus elucidated as the aetiologic agent. Although most initial cases occurred in China, the disease, termed coronavirus disease 2019, has become a pandemic and continues to spread rapidly with human-to-human transmission in many countries. This is the third novel coronavirus outbreak in the last two decades and presents an ensuing healthcare resource burden that threatens to overwhelm available healthcare resources. ⋯ Based on the Chinese experience, some 19% of coronavirus disease 2019 cases develop severe or critical disease. This results in a need for adequate preparation and mobilisation of critical care resources to anticipate and adapt to a surge in coronavirus disease 2019 case-load in order to mitigate morbidity and mortality. In this article, we discuss some of the peri-operative and critical care resource planning considerations and management strategies employed in a tertiary academic medical centre in Singapore in response to the coronavirus disease 2019 outbreak.

Use of Telestroke to Improve Access to Care for Rural Patients With Stroke Symptoms.
Cerebrovascular accident, or stroke, is a common cause of death or disability. Timely diagnosis and intervention are critical for improving survival rates and reducing the long-term effects of stroke. For patients with ischemic stroke, thrombolytic drugs and endovascular intervention are time-sensitive treatment options. ⋯ Rural patients with stroke symptoms may experience a delay in care or stroke diagnosis due to distance to specialized neurologic services. Telestroke consultation is a successful method for timely diagnosis of stroke and recommendation for treatment.
