Etomidate associated with increased mortality in sepsis: meta-analysis

Etomidate: Unsafe for Intubation in Patients with Sepsis? by Blair Westerly, MD Etomidate is commonly used for rapid sequence intubation; however, even after one dose, it has been associated with adrenal axis suppression in critically ill patients. Though both adrenal insufficiency and increased mortality in sepsis have been associated with etomidate, the relationship of the [... read more]

Azithromycin reduces exacerbations in non-CF bronchiectasis (RCT)

Azithromycin for non-CF Bronchiectasis Bronchiectasis — the permanently dilated, tortuous bronchi that can result after previous lung infections — is a frustrating problem for pulmonologists to treat, but not nearly as frustrating as it can be for patients to live with. People with bronchiectasis are plagued by chronic coughing, and many experience a steady decline [... read more]

Femoral lines might not be so bad after all for infection risk

“We’ve got to get that femoral line out of there!” The attending’s face as he says it shadowed with a simmer of fear, a dash of anger. How could the moonlighter have been so incompetent or lazy as to choose the benighted femoral site for a central venous line when the internal jugular and subclavian [... read more]

Can procalcitonin help guide therapy for suspected pneumonia & other infections? (Review)

Procalcitonin to Guide Treatment of Pneumonia (More PulmCCM Topic Reviews) With mounting evidence for its utility as a biomarker for pneumonia, procalcitonin is one of the hottest 2012 topics in pulmonary & critical care. Procalcitonin tends to rise quickly as bacterial infections (but not viral infections) develop, increase with the severity of infection, and decline [... read more]

Should lactate clearance replace SvO2 in sepsis protocols?

It started with a friendly pro/con debate in the December 2011 Chest, about whether lactate clearance or mixed venous oxygen saturation is a better “goal” for early goal-directed therapy in severe sepsis and septic shock. It ended with Alan Jones reviving the rumors and innuendo that have swirled for years around Emanuel Rivers’s body of work. Continuous [... read more]

Hydroxyethyl starch fries kidneys in another large trial (RCT)

Hydroxyethyl Starch (Voluven) Causes Kidney Failure In Large Trial Hydroxyethyl starch (HES) was already wearing a scarlet letter as an potentially dangerous volume resuscitation agent for patients in shock, after evidence emerged this year that hydroxyethyl starch kills people with severe sepsis. Now, another huge, convincing trial shows that hydroxyethyl starch (Voluven) damages kidneys and [... read more]

Azithromycin associated with cardiovascular death

(image: Rxhealthdrugs.com) People taking 5 days of azithromycin had a very small absolute increased risk of death, especially due to cardiovascular causes, compared to people taking amoxicillin, in a retrospective cohort review by Wayne Ray, Katherine Murray, and C. Michael Stein published in the May 17 New England Journal of Medicine. Erythromycin and clarithromycin (the other [... read more]

Xigris' epitaph: "I Never Worked a Day in My Life" (PROWESS-SHOCK)

Recombinant human activated protein C or dotrecogin alfa — better known as Xigris, by Eli Lilly — seemed a godsend when it was first approved for treatment of severe sepsis in 2001. Xigris’ FDA approval (despite an evenly split 10-10 vote) was based solely on the Eli Lilly-funded PROWESS study, a phase 3 randomized trial [... read more]

Surviving Sepsis Guidelines Updated: Preview from SCCM Meeting

More: Surviving Sepsis Guidelines Review / Update The Surviving Sepsis Campaign is a collaboration between the U.S. Society of Critical Care Medicine (SCCM), the European Society of Intensive Care Medicine, and the International Sepsis Forum, whose recommendations on the management of sepsis are considered widely. At the 2012 SCCM meeting, the Surviving Sepsis committee revealed [... read more]

Pleural catheters equal to pleurodesis for dyspnea relief from malignant effusions (TIME2)

(image: Wikipedia) In the TIME2 randomized trial published in the June 13 2012 JAMA, indwelling pleural catheters and talc pleurodesis were equivalent at reducing dyspnea over the 6 weeks following the procedure among 106 patients with malignant pleural effusions. Most patients receiving pleural catheters required no hospital stays, and overall had fewer repeat procedures than those [... read more]

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]
