Assessment of the adequacy of oxygen delivery
In this article, we review physiologic principles of global oxygen delivery, and discuss the bedside approach to assessing the adequacy of oxygen delivery in critically ill patients. Although there have been technological... read more
Carbonic anhydrase inhibitors in patients with respiratory failure and metabolic alkalosis
In patients with respiratory failure and metabolic alkalosis, carbonic anhydrase inhibitor therapy may have favorable effects on blood gas parameters. In mechanically ventilated patients, carbonic anhydrase inhibitor therapy... read more
Ultrasound as a Screening Tool for Central Venous Catheter Positioning and Exclusion of Pneumothorax
Although real-time ultrasound guidance during central venous catheter insertion has become a standard of care, postinsertion chest radiograph remains the gold standard to confirm central venous catheter tip position and rule... read more
Identifying associations between diabetes and ARDS in patients with AHRF
Diabetes mellitus is a common co-existing disease in the critically ill. Diabetes mellitus may reduce the risk of acute respiratory distress syndrome (ARDS), but data from previous studies are conflicting. The objective of... read more
A retrospective observational study of acquired subglottic stenosis using low-pressure, high-volume cuffed endotracheal tubes
The safety of cuffed endotracheal tubes in the neonatal and critically ill pediatric population continues to be questioned due to the theoretical risk of acquired subglottic stenosis. The incidence of acquired subglottic... read more
The Impact of Frailty on ICU Outcomes
Functional status and chronic health status are important baseline characteristics of critically ill patients. The assessment of frailty on admission to the intensive care unit (ICU) may provide objective, prognostic information... read more
Antipsychotic Prescribing Patterns During and After Critical Illness
In this study, antipsychotics were used to treat nearly half of all antipsychotic-naïve ICU patients and were prescribed at discharge to 24% of antipsychotic-treated patients. Treatment with an atypical antipsychotic greatly... read more
Differences in attitudes towards end-of-life care among intensivists, oncologists and prosecutors in Brazil
There is great variability in end-of-life care and the legal context may interfere with decisions on limitation of medical treatment. In Brazil, end-of-life care was initially regulated in 2006, but legal controversies still... read more
The impact of age on the innate immune response and outcomes after severe sepsis/septic shock in trauma and surgical ICU patients
Aged, critically ill surgical patients have greater organ dysfunction and incidence of adverse clinical outcomes after sepsis. Biomarker profiles suggest an immunophenotype of persistent immunosuppression and catabolism.... read more
Blood test may obviate need for head CTs in brain trauma evaluation
A biomarker test based on the presence of two proteins in the blood appears to be suitable for ruling out significant intracranial injuries in patients with a history of mild traumatic brain injury (TBI) without the need... read more
Erasing Death: The Science That Is Rewriting the Boundaries Between Life and Death
Dr. Sam Parnia, Director of the AWARE Study (AWAreness during REsuscitation) and one of the world's leading experts on the scientific study of death and near-death experiences (NDE), presents cutting-edge research from the... read more
Positive Topline Results for Novel Alzheimer’s Drug
A novel drug is showing promise for helping improve cognition in patients with mild to moderate Alzheimer's disease (AD), according to new topline results. A phase 3 trial of more than 800 patients showed that those who were... read more
Electrical Impedance Tomography in ARDS
Acute respiratory distress syndrome (ARDS) is a clinical entity that acutely affects the lung parenchyma, and is characterized by diffuse alveolar damage and increased pulmonary vascular permeability. Currently, computed... read more
Nurse intuition may play a role in critical-care outcomes
Nurse intuition doesn't sound scientific, but it could play a key role in critical-care outcomes, according to a small study published in DovePress. The researchers conducted a descriptive phenomenological study, interviewing... read more
Patterns of Early Crystalloid Resuscitation Provided to Sepsis and Septic Shock Patients
Patterns and Outcomes Associated With Timeliness of Initial Crystalloid Resuscitation in a Prospective Sepsis and Septic Shock Cohort. Crystalloid was initiated significantly later with comorbid heart failure and renal failure,... read more
PPIs do not increase risk for C. difficile infection in ICU
Proton pump inhibitors are not associated with an increased risk for Clostridium difficile infection in ICU patients, according to the results of a retrospective cohort study. PPI use was not associated with a significant... read more
Comparison of Two Lidocaine Administration Techniques on Perceived Pain From Bedside Procedures
Bedside procedures are exceedingly common. Data regarding the severity of procedural pain and strategies to mitigate it are important for the informed consent process and patient satisfaction. Overall, pain reported from... read more
Early Mobilization in the PICU
Mobilization of critically ill children, many with central lines, endotracheal tubes, and other life-saving devices, is associated with potential risks and complications. Hence, concerns about safety often guide staff perceptions... read more
