Recent studies suggest that hypotension thresholds in current guidelines might be too low for older patients due to arterial stiffening, possibly leading to insufficient fluid resuscitation. We compared intravenous (IV) fluid volumes that older (≥ 70 years) and younger ( Read More | Comment

Not many aspects of Emergency Medicine define our specialty better than resuscitation, and few concepts exemplify resuscitation better than shock and intubation. Yet few words together strike greater fear in the minds of savvy resuscitationists. Not because we cannot deftly manage shock, or because we are anything but hardy intubators, but because the swiftest way to transform a living patient into a dying patient or... Read More | Comment

Use of vasopressor for traumatic hemorrhagic shock was associated with mortality after controlling for biases (trauma severity; volume of fluid resuscitation). Among 236,698 trauma patients, 3,551 were included in the study. Overall, 198 of 459 patients (43%) in the vasopressor+ group expired compared with 481 of 3,092 patients (16%) in the vasopressor– group. Three-thousand five-hundred fifty-one traumatic hemorrhagic shock patients who had systolic hypotension (<... Read More | Comment

Acute kidney injury (AKI) is a frequent postoperative complication with a substantial risk for both short and long-term adverse events, and its incidence is likely to rise because of increasing major surgical procedures. Studies investigating better strategies to prevent and treat AKI in this population are urgently needed.Postoperative AKI affects approximately one-fifth of patients after major surgery, but the incidence varies according to the type...

Among patients with severe traumatic brain injury (TBI), early prophylactic hypothermia compared with normothermia did not improve neurologic outcomes at 6 months. These findings do not support the use of early prophylactic hypothermia for patients with severe traumatic brain injury. Among 511 patients who were randomized, 500 provided ongoing consent (mean age, 34.5 years [SD, 13.4]; 402 men [80.2%]) and 466 completed the primary outcome... Read More | Comment

In adult patients with septic shock and high circulating endotoxin activity, does the use of polymyxin B hemoperfusion therapy significantly decrease 28-day mortality? Among patients with septic shock and high endotoxin activity, polymyxin B haemoperfusion treatment plus conventional medical therapy compared with sham treatment plus conventional medical therapy did not reduce mortality at 28 days. High endotoxin activity is associated with multi-organ failure and increased... Read More | Comment

If you mainly treat adults or both adults and children like me, then you have probably heard the (very annoying) quote, “kids are not just small adults”, and so I won’t say it again. Well, I guess I just did, but at least I wont stop at this quote, but attempt to explain how kids are not small adults, and how this may impact their... Read More | Comment

Currently, several medications are recommended for the management of atrial fibrillation with rapid ventricular response in the emergency department including calcium channel blockers, beta blockers and digoxin (the optimal choice is still up for debate). Magnesium sulfate may play a role as a supplemental medication based on its ability to decrease the frequency of sinus node depolarization, prolongation of the refractory period of the atrioventricular...

Acute kidney injury (AKI) in the perioperative period is a common complication and is associated with increased morbidity and mortality. A standard definition and staging system for AKI has been developed, incorporating a reduction of the urine output and/or an increase of serum creatinine. Novel biomarkers may detect kidney damage in the absence of a change in function and can also predict the development of... Read More | Comment

Vasopressors are used in sepsis when hypotension is assumed to be mainly due to a decreased arterial tone. However, the appropriate time to initiate vasopressors is not clearly defined, and fluid administration is most often prioritized with potential risks of fluid overload and persistent hypotension, all events associated with increased mortality. We thus need relevant easy-to-obtain markers of decreased arterial tone to appropriately initiate a... Read More | Comment

Although administration of clonidine is often associated with bradycardia and hypotension, these complications do not seem clinically significant in a mixed PICU population with a high degree of disease severity. Clonidine may have a vasoactive-inotropic sparing effect. The primary endpoints were the prevalences of bradycardia and hypotension. Secondary endpoints were changes in heart rate, blood pressure, Vasoactive-Inotropic Score, COMFORT Behavior score (a sedation scoring scale),... Read More | Comment

Effective antimicrobial administration within the first hour of documented hypotension was associated with increased survival to hospital discharge in adult patients with septic shock. Despite a progressive increase in mortality rate with increasing delays, only 50% of septic shock patients received effective antimicrobial therapy within 6 hrs of documented hypotension. The main outcome measure was survival to hospital discharge. Among the 2,154 septic shock patients... Read More | Comment

Magnesium sulfate has been used as an adjunct medication for the treatment of atrial fibrillation (AF) due to its ability to lessen sinus node depolarization via calcium antagonism. Prior studies investigating magnesium in rapid AF administered varying dosages, often targeted post-surgical patients, and had small sample sizes. Dr. Bryan Hayes summarized previous studies on Academic Life in Emergency Medicine in 2016, focusing on IV magnesium... Read More | Comment

Septic shock is defined as sepsis with hypotension refractory to fluid challenge and requiring vasopressor support combined with an increase in arterial lactate reflecting impaired cellular energy metabolism and dysoxia. Te use of vasoactive drugs to restore mean arterial pressure (MAP) is strongly recommended by the Surviving Sepsis Campaign and the Task Force of the European Society of Intensive Care Medicine (ESICM) on circulatory shock...

Sepsis remains a major scientific and medical challenge, for which, apart from significant refinements in supportive therapy, treatment has barely changed over the last few decades. During sepsis, both vascular tone and vascular integrity are compromised, and contribute to the development of shock. The free circulating peptide adrenomedullin (ADM) is involved in the regulation of the endothelial barrier function and tone of blood vessels. Several... Read More | Comment
