Longtime readers of PulmCCM will remember, there once was an app for iPhone and Android phones. Then, one day, there wasn’t. Technical difficulties, etc. Then, just when everyone had almost forgotten about it, the app was back!

E-cigarettes fuss over formaldehyde: don't believe the hype (yet)

Electronic cigarettes (e-cigarettes) work via a heating element that the user activates while inhaling. Nicotine, along with a liquid solvent (usually propylene glycol), flavorings and whatever else is in the solution are vaporized (aerosolized, really) at the high temperature and inhaled by the user. E-cigarette sales are now a $1.5 billion/year business, growing by an [… read more]

ICU Physiology in 1,000 Words: Cardiopulmonary Resuscitation

Cardiopulmonary Resuscitation by Jon-Emile S.

In Defense of the Central Venous Pressure Jon-Emile S. Kenny M.D. In the waning days of my fellowship I received a hemoptysis consult in the cardiac care unit. Sifting through CT scans, I overheard two house-officers giving sign-out for the evening. When reviewing the clinical data, one of the residents referred to the central venous pressure [… 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]

ICU Physiology in 1,000 Words: Stroke Volume Variation and the Concept of Dose-Response

Stroke Volume Variation and the Concept of Dose-Response Jon-Emile S. Kenny M.D. Awareness of the undulating pattern of an arterial line tracing is high amongst health professionals in the intensive care unit; certainly this is an aftereffect of a cacophony of studies and reviews pertaining to pulse pressure variation and fluid responsiveness in the operating [… read more]

New 2014 Pulmonary Hypertension guidelines released

The American College of Chest Physicians (unaffiliated with PulmCCM) published its new consensus guidelines in August 2014 for the drug treatment of pulmonary arterial hypertension (PAH). They’re free to view on the Chest website, and well worth a look. Remember that pulmonary arterial hypertension (PAH) is but one small subset (“Group 1″) of the much larger [… read more]

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]

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]

Asthma Childhood obesity increases the risk for asthma, and obesity is also strongly associated with asthma in adults.

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: 13 January 2015. During critical illness, catabolism (breakdown of muscle protein, fat and other complex molecules) occurs faster than anabolism (synthesis of these same macromolecules). Historically, the major [… 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]
