Hydroxyethyl starches kill people with severe sepsis; use crystalloid instead (RCT)

Colloids are believed to be more effective expanders of plasma volume than crystalloids, making them a tempting therapy to use for patients in septic shock and other causes of hemodynamic instability. Problem is, some colloid solutions seem to kill people. The VISEP Trial using hydroxyethyl starch 200 kDa/0.5 demonstrated that this high molecular weight HES [… read more]

Linezolid (Zyvox) good for MDR, XDR tuberculosis (RCT)

Linezolid (Zyvox) for XDR-TB: New Hope, New Caution Approved by the FDA in 2000 for drug-resistant gram positive bacterial infections, linezolid (Zyvox, Pfizer) has in clinical practice been mainly used for skin infections and the occasional pneumonia due to methicillin-resistant Staph aureus (MRSA). Now linezolid looks to be effective as an adjunct therapy for multi-drug resistant [… read more]

Normal saline: toxic to kidneys? Chloride solutions may cause renal failure

Does Normal Saline Cause Acute Renal Failure? To internal medicine-trained physicians in the U.S., normal saline solution seems as harmless and healthy as mother’s milk. Intensivists trained in anesthesia or surgery might more often mention normal saline’s hypertonicity compared to blood, and its propensity to cause hyperchloremia, compared to lactated Ringer’s or similar solutions. But [… read more]

Vitamin D is for "doesn't do diddly" for the common cold (RCT)

Extra Vitamin D Doesn’t Prevent Colds in Healthy Adults (JAMA) It looks like you can add Vitamin D to list of supplements (echinacea, vitamin C, etc.) who’ve gone up against the common cold and lost. (Scorekeepers will note that zinc held its own, though, in a Cochrane analysis.) Vitamin D plays an important role in immune responses, [… read more]

Surviving Sepsis Guidelines: Criteria for diagnosis of sepsis

Surviving Sepsis Guidelines’ Criteria for Sepsis Diagnosis See all the Surviving Sepsis Guidelines According to the Surviving Sepsis Guidelines, a sepsis diagnosis requires the presence of infection, which can be proven or suspected, and 2 or more of the following criteria: Hypotension (systolic blood pressure < 90 mm Hg or fallen by >40 from baseline, [… read more]

Assess the IVC for fluid responsiveness with ultrasound (EMCrit Video)

Have you seen EMCrit.org? It’s the brainchild of Scott Weingart, an ED intensivist in New York City. ED docs like to do things (not just debate and deconstruct them endlessly like us pulmonologist-intensivists). In that spirit, Scott’s site is in my opinion more practical, “virtual-hands-on,” and skills/procedure-based than PulmCCM.org. Here’s a great example — his [… read more]

How many times has giving empiric antibiotics saved your professional behind?

Physicians who liberally prescribe empiric antibiotics are often maligned as irresponsible or unthinking by condescending colleagues and policy wonks. But are these doctors actually courageous and prudent, saving countless lives every year by refusing to bend to misguided pressure from antibiotic-conserving paper-pushers? As antibiotic resistance has emerged, many hospitals have begun requiring physicians to provide [… read more]

Meropenem + moxifloxacin: no improvement over meropenem alone in severe sepsis (RCT)

In the first randomized trial of its kind, patients with severe sepsis or septic shock who were given meropenem alone had equivalent clinical outcomes to patients who were given combination therapy including meropenem and moxifloxacin. The results, reported in JAMA, provide ethical support to critical care physicians who prefer to be conservative antibiotic stewards. But [… read more]

Blood pressure cuffs vs arterial lines for hypotensive patients

If you and your team just can’t get an arterial line into your critically ill, hypotensive patient for continuous invasive blood pressure measurement, you may be somewhat comforted by the findings of Karim Lakhal, Christine Macq, Xavier Capdevila et al in the April 2012 Critical Care Medicine. They found that among 150 critically ill patients [… read more]

Ventilator bundles (VAP bundles) not evidence-based, shouldn't be standard care

(image: Wikipedia) Anyone who has ever rounded in an ICU with a nurse manager knows that challenging or questioning the utility of the ventilator associated pneumonia (VAP) bundle is a losing proposition — one likely to get you labeled as a wiseguy troublemaker. Thanks to ventilator bundles’ endorsement by the nonprofit Institute for Healthcare Improvement, [… read more]

Pertussis underdiagnosed; adult booster-vaccine prevents "whoop" & infant deaths

This gentleman (not pictured in the photo) graciously allowed himself to be videotaped in the midst of a severe whooping cough episode caused by Bordetella pertussis; the video is posted on the New England Journal’s website. He had not been vaccinated: vaccination during childhood greatly reduces the risk of severe or life-threatening pertussis infection, and reduces [… read more]

Fever reduction improves early mortality in septic shock? Take a closer look

by Scott Aberegg, MD, MPH It is rare occasion that one article allows me to review so many aspects of the epistemology of medical evidence, but alas Schortgen et al afforded me that opportunity in the May 15th issue of AJRCCM. The issues raised by this article are so numerous that I shall make subsections for each one. [… read more]

Do you have cooties? MDR-bug transmission rates in ICUs (Crit Care Med)

(image: flickrCC) Foam in, foam out, gown on, gown off … ah, the tedium of practicing critical care medicine in the age of rampant, lethal, multi-drug resistant bacteria. As a reminder to keep your guard up and your gear on, here’s a yucky study from Daniel Morgan, Elizabeth Rogawski, and Anthony Harris of the University [… read more]

Watch out for staph coinfections in severe influenza pneumonia (MMWR)

The CDC announced in its Morbidity and Mortality Weekly Report (MMWR) the sad story of three members of a close-knit Maryland family who all died within days of each other from pneumonia due to seasonal influenza A (H3N2) with methicillin-resistant Staph aureus (MRSA) co-infection. Three additional family members acquired the same influenza A strain (which was [… read more]

Release the data on Relenza and Tamiflu, Cochrane implores Pharma (NYT)

Antiviral drugs oseltamivir (Tamiflu) and zanamivir (Relenza) made big bucks for Roche and GSK respectively during the H1N1 influenza pandemic: Roche reportedly sold  about $3 billion of Tamiflu in 2009. Although sales have dropped off precipitously, the drugs are still recommended by CDC for serious cases of seasonal influenza. But do Relenza and Tamiflu even [… read more]

Amoxicillin speeds resolution of acute sinus infections, but imperceptibly? (RCT, JAMA)

Amoxicillin may hasten the recovery from acute sinusitis (sinus infections), with more patients feeling just a tiny bit better after a week of amoxicillin compared to placebo, according to a clinical trial published in the February 15 JAMA. After 10 days, those taking placebo felt as well as those taking antibiotics. You may have heard [… read more]

The Cochrane Collaboration smells a rat around Pharma’s handling of its data on oseltamivir (Tamiflu) and zanamivir (Relenza). They’re taking the unusual step of publicly calling for Roche (Tamiflu) and GlaxoSmithKline (Relenza) to make available their data from the original clinical studies that led to approval of the two blockbuster drugs. They point out that [… read more]

Systemic steroids for severe sepsis and septic shock (Review)

The benefits of corticosteroids as a treatment for severe sepsis and septic shock (if any) are unknown: Although adrenal suppression is common in sepsis, it is still unclear how to assess adrenal function, or whether it should be done at all. The sensitivity and specificity of the cosyntropin (ACTH) stimulation test are unknown, and its [… read more]

C. difficile has always been a foul and disgusting adversary, but lately it’s becoming more formidable and deadly, according to Linda Bobo, Erik Dubberke and Marin Kollef. A few highlights of this excellent review: C.diff infections (CDI) have more than doubled since 2001, to > 340,000 discharges in 2008. Attributable mortality is 6-7%, but may [… read more]

People who survive the initial hyperinflammatory “cytokine storm” of severe sepsis regain their blood pressure, but are at high risk for secondary infection and viral reactivation. Animal models strongly suggest sepsis-induced immune suppression occurring later in the course of sepsis is to blame, but that’s never been proven in humans.
