ReviewSepsis in a Panorama: What the Cardiovascular Physician Should Know.
Sepsis accounts for an estimated 30 million cases and 6 million deaths globally each year. According to a multidisciplinary task force convened by the Society of Critical Care Medicine and European Society of Intensive Care Medicine, sepsis is defined as life-threatening organ dysfunction due to a dysregulated host response to infection. Sepsis is a medical emergency, so much so that the World Health Organization made it a global health priority. ⋯ Septic shock is defined as hypotension with a mean arterial pressure less than 65 mm Hg, requiring vasopressors despite adequate fluid resuscitation and/or lactic acid levels above 2 mmol/L. Both fluid resuscitation and clinical re-evaluation with lactate measurement guide the fluid and vasopressor therapy. Specific guidelines exist for organ support that address mechanical ventilation, blood transfusions, vasopressor choices, and nutrition.

ReviewTelemedicine/Virtual ICU: Where Are We and Where Are We Going?
Intensive care unit telemedicine (tele-ICU) is technology enabled care delivered from off-site locations that was developed to address the increasing complexity of patients and insufficient supply of intensivists. Although tele-ICU deployment is increasing, it continues to cover only a small proportion of ICU patients. This is primarily due to expense, with first-year costs exceeding $50,000 per bed. ⋯ However, more research is required to foster consensus and determine best practices. This review summarizes data on tele-ICU structure, operations, outcomes, and costs. Evidence was extracted from meta-analyses, with secondary data from Cleveland Clinic's tele-ICU experience.

ReviewThe Benefits of Enhanced Recovery After Surgery Programs and Their Application in Cardiothoracic Surgery.
The perioperative care of the surgical patient is undergoing a paradigm shift. Enhanced Recovery After Surgery (ERAS) programs are becoming the standard of care and best practice in many surgical specialties throughout the world. ERAS is a multimodal, multidisciplinary, evidence-based approach to care of the surgical patient that aims to optimize perioperative management and outcomes. ⋯ Data suggest that these pathways have produced not only improvements in clinical outcome and quality of care but also significant cost savings. Large trials reveal an increase in 5-year survival and a decrease in immediate complication rates when strict compliance is maintained with all pathway components. Years of success using ERAS in colorectal surgery have helped to establish a body of evidence through a number of randomized controlled trials that encourage application of these pathways in other surgical specialties.

ReviewIs 24/7 In-House Intensivist Staffing Necessary in the Intensive Care Unit?
Over the past few decades, an increasing number of studies have shown that intensivist-staffed intensive care units (ICUs) lead to overall economic benefits and improved patient outcomes, including shorter length of stay and lower rates of complications and mortality. This body of evidence has convinced advocacy groups to adopt this staffing model as a standard of care in the ICU so that more hospitals are offering around-the-clock intensivist coverage. ⋯ While these arguments may hold true in low-acuity, low-volume ICUs, evidence has shown that in high-acuity, high-volume centers such as teaching hospitals and tertiary care centers, the benefits outweigh the costs. This article explores the history of intensivists and critical care, the arguments for 24/7 ICU staffing, and outcomes in various ICU settings but is not intended to be a comprehensive review of all controversies surrounding continuous ICU staffing.

Review Case ReportsTreatment of Platypnea-Orthodeoxia Syndrome in a Patient with Normal Cardiac Hemodynamics: A Review of Mechanisms with Implications for Management.
Platypnea-orthodeoxia syndrome is a rare entity characterized by dyspnea and hypoxemia in the sitting position and usually resolved by lying down. Although it is not well understood, it is thought to be associated with either intracardiac or extracardiac factors. Within the group of intracardiac etiologies, it typically occurs in the presence of right heart failure or elevated right-sided filling pressures. ⋯ This is a novel case of subacute-onset severe platypnea-orthodeoxia associated with paradoxical embolus occurring while seated in the upright position. The cause of the patient's symptoms may have been progressive kyphosis or to increased pulmonary tidal volumes. Evaluation for platypnea-orthodeoxia is important in cases of occult dyspnea because the condition may be cured by closing the anatomic defect, as it was in this case.
