Fluid Boluses May Improve CRT
Several studies have validated capillary refill time (CRT) as a marker of tissue hypoperfusion, and recent guidelines recommend CRT monitoring during septic shock resuscitation. Therefore, it is relevant to further explore... read more
Hydroxocobalamin Treatment for Vasoplegia-associated Shock
Vasoplegia is generally defined as prolonged vasodilation due to a pathological decrease in systemic vascular resistance, which causes persistent hypotension even in the setting of normal or increased cardiac output. Vasoplegia... read more
Cardiac Index and Heart Rate as Prognostic Indicators for Mortality in Septic Shock
Our retrospective study shows that monitoring cardiac index and heart rate in patients with septic shock may help predict the organismal response and hemodynamic consequences, as well as the prognosis. Thus, healthcare providers... read more
Critical Hypertension in Trauma Patients Following Prehospital Emergency Anesthesia
Delivery of prehospital emergency anesthesia (PHEA) to seriously injured trauma patients risks hemodynamic fluctuation. In adult trauma patients undergoing PHEA, 11.9% of patients experienced post-PHEA critical hypertension.... read more
Revisiting VA-ECMO in Infarct-related Cardiogenic Shock
Despite advances in medical therapies and coronary revascularization, infarct-related cardiogenic shock remains a life-threatening emergency with high death rates. Temporary mechanical circulatory support, including peripheral... read more
The Hemodynamics of Adrenal Veins with Four-dimensional CT Using Quantitative Time-density Curve
Present study quantitatively analyzed adrenal venous flow using four-dimensional computed tomography (4D CT). We reviewed 4D CT images of 55 patients [mean age, 52 years ± 11 (standard deviation); 23 females] who underwent... read more
A Beginner’s Guide to Vasopressors: Inodilators, Inopressors, Methylene Blue, Midodrine: An Essential Manual to Understanding Cardiac Medications and Cardiovascular Hemodynamic Mechanics
The use of pressors and dilators are common in intensive care units, especially concerning the heart. With different mechanisms of action and titrations, it is essential to know how each of the drugs perform and the potential... read more
Neonatology Questions and Controversies: Neonatal Hemodynamics
Dr. Richard Polin's Neonatology Questions and Controversies series highlights the toughest challenges facing physicians and care providers in clinical practice, offering trustworthy guidance on up-to-date diagnostic and treatment... read more
Introduction to Hemodynamics
This book presents a bibliographical work on the modeling of blood dynamics. The first chapter describes the anatomy of the cardiovascular system and the functioning of the blood circulation. The second chapter is devoted... read more
Beware the Painless Pulmonary Embolism
Many EPs know that myocardial infarction can be painless in about 20 percent of cases but are unaware that the same is true of pulmonary embolism. Many conditions, in fact, that are typically quite painful are actually... read more
Optimal Fluid Therapy for Sepsis Management in Critically Ill Adults
For a study, researchers aimed to analyze the fluid treatment in septic critically ill adults. About 20% to 30% of patients were admitted to an ICU with sepsis. In sepsis patients, investigators observed intravenous fluid... read more
Acute Kidney Injury in ICU Patients
Patients admitted to the intensive care unit are prone to various complications, one of which is acute kidney injury (AKI). The etiology of acute kidney injury can be multifactorial. Among the various causes, sepsis remains... read more
High-risk Pulmonary Embolism in the ICU
According to the European guidelines, high-risk pulmonary embolism (PE) is defined as PE associated with hemodynamic instability, including sustained hypotension, cardiogenic shock and/or cardiac arrest. High-risk PE... read more
Tube Thoracostomy in Emergency Department
Using trauma video review we identified significant procedural variability in emergency department tube thoracostomy, mainly that hemodynamic abnormality led to lower proficiency scores and increased malpositioning. Efforts... read more
Mechanical Power: Meaning, Uses and Limitations
Ventilator-induced lung injury (VILI) carries significant attributable mortality in acute respiratory distress syndrome (ARDS). Even though all the ventilatory variables contribute to VILI, current guidelines focus almost... read more
Workbook on Hemodynamic Management
This workbook focuses on hemodynamics management. Hemodynamic management should be aimed at minimizing the ischemic injury. Cerebral ischemia impairs the brain's ability to autoregulate its circulation through vasoconstriction... read more
Dexmedetomidine vs. Propofol Sedation in Critically Ill Adults Requiring Mechanical Ventilation
Dexmedetomidine did not significantly impact ICU length of stay compared with propofol, but it significantly reduced the duration of mechanical ventilation and the risk of delirium in cardiac surgical patients. It also significantly... read more
