FDA warns of aortic dissection with fluoroquinolones

After a review of reported adverse events, the U.S. FDA is warning physicians that fluoroquinolone antibiotics may increase the occurrence of aortic dissections, resulting in aortic rupture and death. FDA used unusually direct language in advising, “Fluoroquinolones should not be used in patients at increased risk unless there are no other treatment options available.” Patients [… read more]

Cricoid pressure no help during endotracheal intubation in large trial

Pressing fingers against the cricoid cartilage (the Sellick maneuver) during rapid sequence intubation compresses the esophagus beneath the firmer trachea. It has long been espoused that this prevents aspiration (emesis or reflux of gastric contents into the supraglottic space and airway, obscuring the operator’s view and harming the patient). The Sellick maneuver is believed to [… read more]

Decontaminating patients did not reduce bloodstream infections

A large proportion of patients who remain in ICUs for more than a few days develop hospital-acquired infections, including bloodstream infections. Indwelling urinary or venous catheters, gut translocation, aspiration and impaired host defenses can all be causative. Bloodstream infection incidence has been reduced over time, but remains persistently ineradicable. One enticing method of prevention has been [… read more]

For most critically ill patients, a 'starvation diet' seems just fine (TARGET trial)

Very little evidence guides nutrition in critical illness. Because of critically ill patients’ catabolic state, and probably influenced by the normalization fallacy, nutrition practices often include efforts to provide daily calories in the 1,800 – 2,000 range. However, anorexia may be adaptive during illness (since it is common to multiple disease states); greater enterally infused [… read more]

Is Critical Care Medicine becoming a Cargo Cult of Vitamin C?

By Nicholas Mark, MD During the 1940s, many Melanesian cultures were profoundly altered as the Second World War was waged in the Pacific around them. Western soldiers constructed airstrips out of the jungles and the natives witnessed vast wealth in the form of manufactured goods literally rain down from the skies on parachutes or carried [… read more]

Vitamin D supplementation reduced COPD exacerbations in deficient patients: meta-analysis

by Salynn Boyles, Contributing Writer, MedPage Today Vitamin D supplements reduced moderate to severe COPD exacerbations in patients with low circulating levels of its 25-hydroxyvitamin D (25-OH-D) metabolite at baseline, a meta-analysis indicated. But no such effect was seen for patients with at least normal 25-OH-D levels (at least 25 nmol/L) prior to supplementation, according to Adrian [… read more]

Hospitals should not implement one-hour sepsis bundles, say SCCM and ACEP

In an unusual turn, the Society for Critical Care Medicine (SCCM) is advising against implementation of the one-hour sepsis bundle originally advocated in Spring 2018 by committee members of its Surviving Sepsis Campaign. SCCM and American College of Emergency Physicians (ACEP) issued a joint statement in which they acknowledged “concerns expressed about the recently released Surviving [… read more]

Keep O2 saturations at 96% or below for hospitalized patients: expert panel

For acutely ill patients, oxygen saturation should not exceed 96%, an international panel recommended. A multidisciplinary team of clinicians was brought together by The BMJ as part of the Rapid Recommendation initiative to focus on the most effective approach to oxygen therapy for patients with acute medical illness. The team used findings from an April 2018 systematic [… read more]

Dupilumab as add-on biologic improved allergic asthma outcomes

by Salynn Boyles, Contributing Writer, MedPage Today  SEATTLE — Add-on treatment with the biologic therapy dupilumab (Dupixent) was associated with reduced severe exacerbations and improved lung function in patients with allergic asthma in a post-hoc analysis of phase III data from the Liberty Asthma Quest study reported here. The analysis compared outcomes in patients with allergic disease versus those [… read more]

Daily chest X-rays the norm in ventilated patients, despite guidelines

More than 60% of patients receiving mechanical ventilation have continued to receive daily chest x-rays since the publication of guidelines recommending against the practice. The findings came from a database review of hundreds of thousands of patients and were published in JAMA Network Open. The American College of Radiology once recommended daily chest films in [… read more]

Could anti-reflux surgery slow idiopathic lung fibrosis?

by Diana Swift, Contributing Writer, MedPage Today Laparoscopic anti-reflux surgery deserves further investigation for prevention of idiopathic pulmonary fibrosis (IPF) progression in some patients with gastroesophageal reflux disorder (GERD), after favorable results were seen in a phase II study. Known as the WRAP-IPF trial, the study found GERD surgery was safe and well tolerated, with fewer serious adverse [… read more]

More labeled warnings on fluoroquinolones ordered by FDA

Fluoroquinolone warning labels keep getting longer. In 2018 the U.S. FDA ordered stronger cautions about mental health side effects, and severe hypoglycemia causing coma and death. Mental health disturbances now attributed to fluoroquinolones include: Attention disturbances Disorientation Agitation Nervousness Short-term memory loss Delirium The risk of hypoglycemic coma now gets a specific mention on the [… read more]

Why are obese people more likely to survive infections and sepsis?

Obese people are significantly more likely to survive severe illness due to infections, as compared to people with normal weights, according to analyses of three large data sets presented at a European conference. Among more than 1.5 million hospitalizations for pneumonia in the U.S. between 2013-2014, obese patients (BMI > 30) were 29% more likely [… read more]

Delay renal replacement in severe sepsis with acute kidney injury: IDEAL-ICU

Another large study suggests that there is no benefit to early initiation of renal replacement therapy (RRT) in patients with severe sepsis with septic shock and acute kidney injury (AKI). And many patients whose renal replacement was delayed recovered sufficient kidney function to avoid dialysis entirely. Because AKI is associated with worse outcomes in critical [… read more]
