The field of critical care medicine is in the midst of a dramatic change. Technological and scientific advances during the last decade have resulted in a fundamental change in the way we view disease processes, such as sepsis, shock, acute lung injury, and traumatic brain injury. Pediatric intensivists have been both witness to and active participants in bringing about these changes and it is imperative... Read More | Comment

A Novel and Simultaneous Analysis of the Guyton and Rahn Diagrams. Graphical models of physiology are heuristically appealing as they facilitate qualitative conclusions at the bedside of the critically ill. Historically, the Rahn diagram has portrayed the physiology of the lungs, chest wall and respiratory system, while the Guyton diagram has illustrated cardiovascular physiology. As contemporary methods of haemodynamic monitoring, and their predecessors, are inexorably... Read More | Comment

The art of predicting future hemodynamic instability in the critically ill has rapidly become a science with the advent of advanced analytical processed based on computer-driven machine learning techniques. How these methods have progressed beyond severity scoring systems to interface with decision-support is summarized. Using advanced analytic tools to glean knowledge from clinical data streams is rapidly becoming a reality whose clinical impact potential is... Read More | Comment

In a case-control study, there was a statistically significant association between an LOF variant in the TTN gene and early-onset AF, with the variant present in a small percentage of participants with early-onset AF (the case group). Further research is necessary to understand whether this is a causal relationship. Among 2781 participants with early-onset AF (the case group), 72.1% were men, and the mean (SD)...

A 36-year-old man was admitted to the intensive care unit with an acute exacerbation of chronic heart failure. His medical history included heart failure with an ejection fraction of 20%, bioprosthetic aortic-valve replacement for bicuspid aortic stenosis, endovascular stenting of an aortic aneurysm, and placement of a permanent pacemaker for complete heart block. An Impella ventricular assist device was placed for management of acute heart... Read More | Comment

Urgent and drastic changes to the rules around medical devices, such as pacemakers, are needed to protect patients, according to the Royal College of Surgeons. It wants a register of every device in every patient set up so doctors know if new innovations are causing harm. An investigation by 58 media organisations has uncovered patients being given implants that were unsafe. Medical devices range from... Read More | Comment

In a single center’s experience, thrombolytic therapy is used infrequently for the management of cardiac arrest. Thrombolysis during cardiac arrest should be considered on a case-by-case basis and should be utilized only when there is a high suspicion for pulmonary embolism as the cause of arrest and when thrombolytic therapy is readily available. Twenty-six patients were identified. Patients were predominantly male (65%) and Caucasian (89%)... Read More | Comment

Shock has potentially reversible causes of morbidity and mortality if appropriately diagnosed and managed. Older methods of invasive monitoring have significant limitations but are still critical for managing shock in certain patients and settings. Newer methods are easier to employ, but further validation is needed. Multiple modalities along with careful clinical assessment are often useful in distinguishing shock subtypes. Best practice standards for monitoring should... Read More | Comment

Assessment of abdominal aortic calcification using computed tomography (CT) is a highly effective predictor of future heart attack and CVD risk, according to research published in Radiology Oct. 2—more effective even than the Framingham risk score, which has been relied upon for more than two decades. Stacy D. O’Connor, MD, MPH, an assistant professor of radiology at the Medical College of Wisconsin in Milwaukee, led... Read More | Comment

Over the years, IV magnesium has been studied for the treatment of rapid AF in several clinical situations, most prominently in post-cardiac surgery patients. However, there are also studies in ED and cardiology patients, both as a primary therapy and as an adjunct. In fact, two meta-analyses from 2007 evaluated the data (mostly the same studies). Both concluded that magnesium is safe and effective in... Read More | Comment

This practical guide provides a multidisciplinary, clinically oriented approach to the management of patients in intensive care. The book discusses the complete range of specialties, including cardiology, pulmonology, gastroenterology, neurology, toxicology, and much more. Each condition is presented in a step by step process, covering pathophysiology, signs and symptoms, diagnosis, treatment, and other considerations such as age/developmental issues. The comprehensive appendices section covers essential data... Read More | Comment

Tele-stenting appears more possible now than ever, as Vascular Robotics announced an interventional cardiologist used its CorPath GRX System to perform a remote percutaneous coronary intervention (PCI) in a pig 100 miles away. Ryan Madder, MD, navigated the robotic equipment from Ludington, Michigan, while using a telecommunications system to connect with bedside staff in Grand Rapids, Michigan. Madder previously led the REMOTE-PCI study, which showed... Read More | Comment

Collaborative quality improvement and learning networks have amended healthcare quality and value across specialities. Motivated by these successes, the Pediatric Acute Care Cardiology Collaborative (PAC3) was founded in late 2014 with an emphasis on improving outcomes of pediatric cardiology patients within cardiac acute care units; acute care encompasses all hospital-based inpatient non-intensive care. PAC3 aims to deliver higher quality and greater value care by facilitating... Read More | Comment

The increased troponin used to be a straight ticket to the cardiology service. Now, the picture isn't so clear. What do you need to consider in the patient with elevated troponin? Cardiac troponins consist of three proteins: cTnC, cTnI, and cTnT1. These proteins interact with tropomyosin to form a complex that functions as the backbone of striated muscle. This functions in the excitation and contraction... Read More | Comment

Cardiac surgery has been evolving to include minimally invasive, hybrid and transcatheter techniques. Increas‑ing patient age and medical complexity means that critical care management needs to adapt and evolve. Recent advances have occurred in several areas, including ventilation, haemodynamics and mechanical circulatory support, bleeding and coagulation, acute kidney injury, and neurological management. This narrative review describes stand‑ard care, recent advances, and future areas of research... Read More | Comment
