The only VAP prevention method that saves lives is the one you’re not using

There’s always been doubt about the efficacy of the numerous “ventilator bundles” hospitals use to prevent ventilator-associated pneumonia (VAP). A provocative new analysis concludes that none of these methods save lives — except the one that almost no ICUs are using today. Healthcare associated pneumonias (HAP), especially ventilator-associated pneumonias (VAP), are associated with increased mortality, excess antibiotic use, lengthened hospital [… read more]

Antibiotics for community-acquired pneumonia: Is azithromycin out?

Is it time for a change in the standard treatment of community-acquired pneumonia? A new Dutch study says, maybe. The Infectious Diseases Society of America (IDSA) says, not so fast. IDSA’s guidelines for treatment of community acquired pneumonia were last updated in 2007. For patients admitted to the hospital but not needing the ICU, they have [… read more]

Endovascular therapy helps in ischemic stroke, again (ESCAPE)

Endovascular Therapy Improves Outcomes from Ischemic Stroke By Parth Rali, MD and Igor Titoff, DO Endovascular therapy for ischemic stroke has long been an attractive treatment modality for ischemic strokes, but until recently large randomized trials have not confirmed a benefit [1,2,3]. Two of these—IMS III1 and SYNTHESIS2—failed to prove the benefit of endovascular therapy (with-or-without tissue plasminogen activator) [… read more]

ProMISe Trial for Sepsis: Usual Care 3, Goal-Directed Therapy 0*

* (since 2014) The ARISE (Australasia) and ProCESS (U.S.) trials, published in 2014, each demonstrated no advantage of protocolized care for sepsis over conscientious usual care. For those remaining unconvinced, the U.K.-based ProMISe trial is available in the New England Journal of Medicine. ProMISe extends the growing global footprint of what some will call the [… read more]

Chlorhexidine baths in ICU don't prevent infections in large trial

Throwing the Baby out with the (Chlorhexidine) Bathwater? New Data on Disinfectant Baths By Lekshmi Santhosh, MD As a critical care community, we’ve been forever searching for a magic bullet to eradicate healthcare-acquired infections. So when the pair of 2013 NEJM trials on daily chlorhexidine bathing showed statistically significant reductions on the incidence of hospital-acquired [… read more]

E-cigarettes double smokers' quit rates vs placebo: meta-analysis

Electronic cigarettes containing nicotine can double smokers’ rates of quitting at one year, compared to e-cigarettes without nicotine (placebo), according to a new small meta-analysis published in the Cochrane Database of Systematic Reviews. The rates of smoking cessation using nicotine-containing e-cigarettes (9%) were roughly comparable to that seen with other forms of nicotine replacement therapy in past trials. The [… read more]

Chantix works even if you're just thinking of quitting smoking

“Set a quit date to stop smoking,” goes the old bit of doctor’s advice. Experts argue people need to psyche themselves up, get serious, commit to quitting before the last butt goes in the ashtray. A new study in JAMA suggests that advice may be outdated. Smokers unready to quit who took the cessation drug varenicline (Chantix) for several months, [… read more]

Should video-guided intubation be standard training in critical care? (And should anesthesiologists teach it?)

Image: Airwaycam Endotracheal intubation is a routine but high-stakes maneuver, performed uneventfully thousands of times daily throughout the developed world. In the U.S., elective (routine) intubation is almost exclusively the domain of anesthesiologists, who become masters of the technique through thousands of iterations throughout training and their careers. The vast majority of these intubations take [… read more]

Subglottic suctioning prevents ventilator-associated pneumonia

Subglottic suctioning can prevent ventilator-associated pneumonia (VAP), but much of the research showing its benefits was performed prior to wide adoption of the so-called “VAP bundle,” widely believed to reduce VAP incidence. This led some to question any additive benefits of subglottic suctioning. Authors of a new randomized trial found that subglottic suctioning also reduced ventilator-associated pneumonia incidence in a [… read more]

Nutrition in severe pancreatitis: none at all (for 3 days) worked fine

Image: Wikipedia Acute pancreatitis is a common and usually self-limited illness resolving after a few days of rest and not eating. A minority of people develop severe pancreatitis with necrosis, which can transform pancreatitis into an ordeal lasting weeks or months, characterized by multi-organ failure, infections, and a >15% mortality rate. Those infections are believed to be caused by [… read more]

Cytisine for smoking cessation: as good as nicotine replacement -- and cheap

The smoking cessation drug varenicline (Chantix) works by weakly activating and also blocking nicotine receptors in the brain, simultaneously. This neat trick has the dual effects of reducing tobacco cravings while also blunting the “high” from smoking. That combination has made Chantix the most successful smoking-cessation therapy on the market, but it costs about $500 for [… read more]

Ischemic stroke: Interventional treatment + alteplase = new standard of care? (MR CLEAN)

In the early 1990s, the clot-busting drug alteplase (intravenous recombinant tissue plasminogen activator or rTPA) revolutionized stroke treatment when it was shown to significantly increase the chances of a good outcome after ischemic stroke when given in the first 4.5 hours since symptom onset. But alteplase is not a miracle drug. In a meta-analysis of 9 randomized trials, rTPA improved [… read more]

Life after sepsis protocols: What now? (You decide.)

2014 has been a rough year for advocates of sepsis protocols. First, the long-awaited ProCESS trial did not show any benefit from use of the original early goal-directed therapy (EGDT) protocol used in the single-center 2001 trial by Rivers et al that, despite criticism, became the standard of care for the following decade. Patients cared for in the 2 non-EGDT arms [… read more]

Safe to stop inhaled steroids in COPD (and start more expensive drugs)?

Olodaterol People with severe chronic obstructive pulmonary disease (COPD) often have persistent dyspnea or exacerbations despite the use of a single controller inhaler. (Controller inhalers for COPD most often include combination inhaled corticosteroid/long-acting beta agonists like Advair, Dulera and Symbicort [ICS/LABAs] and the long-acting anticholinergic agent Spiriva/tiotropium). These patients often take both a combination ICS/LABA and Spiriva, so-called [… read more]

Total parenteral nutrition vs enteral nutrition: no difference in critically ill? (CALORIES trial)

Feeding patients enterally (nasogastric or nasojejunal tube feedings) has been the standard of care for critically ill patients, based on weak evidence that it reduces infection rates; hence the adage “feed the gut, if you can.” That last caveat is included because so many critically ill patients have gastric motility impairment (with inability to achieve [… read more]

Transfusion for hemoglobin above 7 g/dL: no benefit in septic shock (TRISS Trial)

Blood transfusions have been a central component of protocols for care of severe sepsis and septic shock, ever since the single-center 2001 Rivers trial included them in its interventions. Any benefit (or harm) caused by red cell transfusion independently was unknowable, and so the therapy became standard care as part of the so-called sepsis bundle. The Surviving [… read more]

Are traditional protocols for goal directed therapy for sepsis dead? (ARISE trial)

Update: As astute commenters have mentioned below, and as I stated in our post on the ProCESS trial, protocols of some kind could still have a place in the care of sepsis if they ensure more rapid recognition and thorough treatment. Accordingly, I changed the headline to clarify that it’s only traditional sepsis protocols to which I refer, not the [… read more]
