Which cancer patients need prophylaxis for DVT and pulmonary embolism?

People with cancer have the highest rates of deep venous thrombosis (DVT) and pulmonary embolism (PE). However, the risk of venous thromboembolism varies widely by cancer type and between patients. Daily anticoagulant use can reduce the risk of DVT and pulmonary embolism, but at a cost of increased bleeding risk, patient inconvenience and discomfort, and cost. [... read more]

What are Ventilator-Associated Events (and why should you care)?

Have you heard of ventilator-associated events (VAEs)? Like it or not, this neologism of healthcare-speak is coming to an ICU near you soon. Here’s the lowdown on VAEs and why they matter to the practicing intensivist. What are Ventilator-Associated Events? Ventilator-associated events are an invention of the Centers for Disease Control and Prevention (CDC), created in [... read more]

PulmCCM Roundup #5

The PulmCCM Roundup gathers all the best in pulmonary and critical care from around the web.  Browse all the PulmCCM Roundups. Statins Fail for COPD, ARDS Statins have been optimistically tested as a tonic for everything from diabetes to dementia — so far, without success. That consistency was maintained in 2 recent trials showing statins’ [... read more]

Prone positioning reduces ARDS mortality by 26%: meta-analysis

Image: Rotoprone Acute respiratory distress syndrome (ARDS) injures the lungs in a heterogeneous pattern, and the damaged areas are particularly vulnerable to further ventilator-induced lung injury. This is why a lung-protective ventilator strategy using low tidal volumes reduces mortality from ARDS, experts believe. Tidal volumes of 6 mL/kg ideal body weight (calculated from height) using conventional [... read more]

Using bronchoalveolar lavage to evaluate ILD

Using BAL Cellular Analysis in Interstitial Lung Disease The role of bronchoalveolar lavage (BAL) in diagnosing and managing patients with interstitial lung disease (ILD) has always been uncertain and controversial. BAL findings are usually nonspecific, suggesting rather than proving the existence of any particular noninfectious condition (including interstitial lung disease). That said, in patients with [... read more]

Azithromycin for COPD exacerbations: 2014 Update

Azithromycin to Prevent COPD Exacerbations: What’s New? By Abhishek Biswas, MD Multiple previous studies have suggested likely benefits from using azithromycin as an immunomodulator for cystic fibrosis, bronchiectasis, diffuse panbronchiolitis, post-transplant obliterative bronchiolitis and COPD. This month, a new Cochrane analysis and clinical review in JAMA concludes that “continuous macrolide antibiotic use for prophylaxis [is] associated with a [... read more]

PulmCCM Roundup #4

All the best in pulmonary and critical care from around the web. Browse all the PulmCCM Roundups. Asthma Childhood obesity increases the risk for asthma, and obesity is also strongly associated with asthma in adults. The mechanisms are likely multiple, complex and interdependent (pro-inflammatory mediators, etc.), not simply causative. Losing weight does seem to improve [... read more]

How to provide nutrition for critically ill patients (Review)

Nutritional Support During Critical Illness This PulmCCM topic review will be periodically updated and expanded as new research is published. Originally published 22 September 2013. Most recent update: 16 May 2013. During critical illness, catabolism (breakdown of muscle protein, fat and other complex molecules) occurs faster than anabolism (synthesis of these same macromolecules). Historically, the [... read more]

Red blood cell transfusions increase hospital-acquired infections (meta-analysis)

Red Cell Transfusions Increase Risk for Nosocomial Infection: Meta-Analysis Transfusing blood to anemic patients has an almost irresistible intuitive and theoretical appeal both to physicians and the patients who get transfused. It’s perhaps the archetypal example of the “find it – fix it” approach to doctoring: correct all laboratory abnormalities and ipso facto, the patient [... read more]

Etomidate for intubation in sepsis: what’s the risk, really?  Etomidate has been suspected of causing adrenal insufficiency and potentially death in patients with severe sepsis, when used as an anesthesia-induction agent [... read more]

Bleeding and Coagulation Disorders in the ICU (Review)

Because coagulopathies (an impairment of blood clotting), thrombotic states, and bleeding are all interrelated through the coagulation cascade, and because they occur often in critically ill patients, it makes sense to consider these bleeding and clotting disorders together. That’s what Beverly Hunt did in a review in the February 27 2014 New England Journal of [... read more]

Community Acquired Pneumonia (Review)

Community-acquired pneumonia (CAP) is “ordinary” pneumonia, usually (but not always) caused by one of a short list of pathogens susceptible to common antibiotics. Pneumonia remains one of the main reasons for hospital admissions, and causes an estimated 3.5 million deaths yearly, including more than 50,000 in the U.S. Catching pneumonia also increases the risk for [... read more]

Resuscitation Fluids in Critical Illness (Review)

Resuscitation fluids may be the most common intervention in critical care, with more than 200 million liters of normal saline infused each year in the U.S. alone. However, there is scarce evidence to guide the best use of resuscitation fluids in the ICU. John Myburgh and Michael Mythen’s review article in the September 26 2013 [... read more]

Sedation and Analgesia in the Critically Ill (Review)

Pain, agitation, and delirium are all extremely common in ICU patients–so much so that they’ve been termed the “ICU triad.” No one knows exactly how common each is, because ICU patients are often too delirious to complain of pain; or their agitation hides their delirium; or their unidentified pain may cause their agitation; or ….

Acute Liver Failure: Treatment (Part 2 of 2) See also: Acute Liver Failure: Causes & Initial Management Management of acute liver failure is largely supportive critical care for the multiorgan failure that frequently results.

Ventilator-Induced Lung Injury Review (Part 2 of 2)

Prevention and Management of Ventilator-Induced Lung Injury See also Part 1: Mechanisms of Ventilator-Induced Lung Injury The recognition that lifesaving mechanical ventilation can also be harmful, even lethal, has led to a sea change in the use of mechanical ventilation in critically ill patients — at least in theory. For people with acute respiratory distress [... read more]

Ventilator-Induced Lung Injury Review (Part 1 of 2)

Mechanisms of Ventilator-Induced Lung Injury (Part 1) See also Part 2: Prevention and Management of Ventilator-Induced Lung Injury Although invasive mechanical ventilation saves tens of thousands of lives each year, it can also be harmful, especially when misapplied. The repetitive stretching of lung tissue during positive pressure ventilation can damage fragile alveoli already made vulnerable [... read more]
