Mechanical Ventilation in ARDS: 2014 Update

Mechanical Ventilation in ARDS: 2014 Review (More PulmCCM Topic Updates) People with acute respiratory distress syndrome (ARDS) are by definition severely hypoxemic, and nearly all require invasive mechanical ventilation. Yet mechanical ventilation itself can further injure damaged lungs (so-called ventilator-induced lung injury); minimizing any additional damage while maintaining adequate gas exchange (“compatible with life”) is the [… read more]

Acetaminophen causes childhood asthma, researcher argues

(image: flickrCC) Is acetaminophen responsible for the worldwide rise in childhood asthma over the past 30 years? Citing a mounting pile of circumstantial evidence from epidemiologic observational studies, John McBride of Akron’s Children’s Hospital in Ohio believes so, and that it’s time to officially push the worry button.

Reimbursement for Palliative Care in the ICU By Intensivists To an intensivist, providing palliative care often means having multiple time-consuming and emotionally challenging interactions with families struggling to cope with the impending loss of their loved one.

Fellows: This is your brain on protocols (JAMA)

(image: flickrCC) Do protocols make trainees’ brains go soft? That’s the assertion of more than a few crusty hard-liners who miss the good old days — when you got 2-liter tidal volumes for your ARDS and liked it, dad-gum-it!! Prasad et al can’t say whether critical care fellows can actually run ventilators in the post-protocol [… read more]

Epinephrine in field no help after out-of-hospital cardiac arrest? (JAMA)

(image: Hospira) Akihito Hagihara et al present suggestive data in the March 21 JAMA that giving epinephrine to people with out of hospital cardiac arrest increases their chances of making it to the hospital with a pulse, but not of making it home with decent brain function or functional status. In a prospective observational analysis [… read more]

Cost shifting of asthma meds to patients had little effect on adherence, outcomes (JAMA)

(image: flickrCC) Health insurance plans are shifting an increasing portion of costs for prescription medications onto patients. A recent study in JAMA concluded that such cost shifting decreased asthma medication use and increased hospitalization rates in U.S. children. But the effect, if real, was small. What They Did Pinar Karaca-Mandic et al looked back at [… 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]

How to make $25,000 on each EBUS (Chest)

(image: flickrCC) Endobronchial ultrasound with transbronchial needle aspiration (EBUS-TBNA), when performed by skilled physicians, reduces the need for mediastinoscopy and unnecessary thoracotomies with their associated morbidity, and is poised to permanently alter the landscape of lung cancer diagnosis and staging. Prior to 2008, Medicare seemed to recognize the potential value of EBUS by paying hospitals [… read more]

Should you check pleural manometry during thoracentesis?

(image: Cardinal Health) Should you routinely check pleural pressures with bedside manometry during thoracentesis? David Feller-Kopman of Johns Hopkins says, of course: it’s zero risk, zero cost, only seconds of extra time, and provides potentially useful clinical information. Specifically, one can identify people with “entrapped lung” and “trapped lung”: Identifying “Entrapped Lung” by Pleural Pressures [… read more]

Texting resident fails to stop warfarin; hemopericardium ensues

Texting while doctoring is a newly hyped threat to patient safety. Multitasking and the constant flow of new distracting information in the form of alarms, interruptions, pages, etc. have always been inherent to the practice of medicine. But some are wondering if the ubiquitous temptations of personal social media-enabled smartphones and tablets in the medical [… read more]

(image: Plioz.com) Ever cared for that patient with metastatic cancer in your ICU, intubated for acute respiratory failure and surrounded by a bewildered and stressed family who cope by emotionally blaming you, the intensivist, because “He just saw his oncologist last week, and he said everything was OK!”?

NYT runs press release for new OSA treatment Provent. Does it work?

Provent is the trade name for disposable, stick-on nose plugs made by Ventus Medical that are a relatively new (second-line) treatment for obstructive sleep apnea. The bandage-like device has pinholes cut in the nostrils that let air in during inspiration, but create back pressure during exhalation, helping prevent airway collapse.

Vitamin D supplements don't prevent COPD exacerbations in RCT (Ann Intern Med)

Vitamin D deficiency has been linked to many chronic medical conditions, including asthma and chronic obstructive pulmonary disease (COPD). In some cases, more severe vitamin D deficiency is associated with more severe chronic illness. However, it’s never been shown that vitamin D deficiency supplemenation improves or prevents illness; i.e., that vitamin D deficiency causes or exacerbates [… 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]
