Mythbuster: Administration of Vasopressors Through Peripheral Intravenous Access
Vasopressors are frequently used in critically ill patients with hemodynamic instability both in the emergency department (ED) as well as intensive care units (ICUs). Typically, vasopressors are given through central venous... read more
Testing Epinephrine for Out-of-Hospital Cardiac Arrest
Despite having a powerful effect on restoring spontaneous circulation after out-of-hospital cardiac arrest, epinephrine produced only a small absolute increase in survival with no increase in favorable functional recovery... read more
Vitamin C: Should We Supplement?
A short course of intravenous vitamin C in pharmacological dose seems a promising, well tolerated, and cheap adjuvant therapy to modulate the overwhelming oxidative stress in severe sepsis, trauma, and reperfusion after ischemia.... read more
Continuous EEG Monitoring Remains Underused in Critically Ill
A retrospective cross-sectional study found that despite the fact that continuing electroencephalography (cEEG) use was associated with lower in-hospital mortality in critically ill patients, cEEG is underutilized. Experts... read more
Dual Antiplatelet Therapy with Aspirin and Clopidogrel for Acute High Risk Transient Ischemic Attack and Minor Ischemic Stroke
What is the role of dual antiplatelet therapy after high risk transient ischemic attack or minor stroke? Specifically, does dual antiplatelet therapy with a combination of aspirin and clopidogrel lead to a greater reduction... read more
The Myth of Vasopressors and Ischemia
Despite the widespread clinical use, and their well-documented life-saving properties, vasopressors are often maligned, accused of causing ischemia to fingers, toes, mesentery, kidneys, and so forth. Not only is the evidence... read more
Cerebral Autoregulation in the Prediction of Delayed Cerebral Ischemia and Clinical Outcome in Poor-Grade Aneurysmal Subarachnoid Hemorrhage Patients
High initial pressure reactivity index, presumably reflecting early brain injury, but not oxygen reactivity index, was associated with delayed cerebral ischemia and worse clinical outcome in poor-grade subarachnoid hemorrhage... read more
Cardiovascular Testing and Clinical Outcomes in Emergency Department Patients With Chest Pain
In patients who present to the emergency department with chest pain without evidence of ischemia, is cardiac testing - noninvasive testing or coronary angiography - associated with changes in revascularization or acute myocardial... read more
The Sick Bowel Obstruction Patient
A 68-year-old female presents to the ED with abdominal pain, bloating, and nausea which she states began this morning upon wakening about 3 hours prior to arrival. She appears moderately uncomfortable and pale. She is urgently... read more
Cellular Mechanisms of Prevention of Ischemia-Reperfusion Injury
Ischemic preconditioning is the phenomenon whereby brief periods of sublethal ischemia protect against a subsequent, more prolonged, ischemic insult.... read more
