Apixaban (Eliquis) Prevents Recurrent DVT-PE Long-Term People with unprovoked venous thromboembolic disease (pulmonary embolism or deep venous thrombosis, or DVT) are at high risk for recurrence, and current ACCP guidelines advise consideration of “indefinite” anticoagulation. Warfarin (Coumadin) is a wonder drug efficacy-wise, reducing the risk of pulmonary embolism and deep venous thrombosis by ~90%. However, [... read more]
Families Allowed to Witness CPR Felt Better, Had Fewer Regrets Should family members be allowed, or even encouraged, to witness the health care team’s attempts to revive their family member with CPR after a cardiac arrest? In the interests of openness and transparency, many have argued “yes,” with the thought that witnessing the heroic efforts [... read more]
(image: Wikipedia) High-Frequency Oscillatory Ventilation (HFOV) for ARDS Two Randomized Trials: Early HFOV Doesn’t Help, May Harm High-frequency oscillatory ventilation (HFOV) has been proposed as a first-line therapy for acute respiratory distress syndrome (ARDS). By delivering 3-15 breaths per second of tiny tidal volumes (~70 mL), HFOV has appeal as the “ultimate” lung protective ventilator [... read more]
Weaning From Mechanical Ventilation Update (See More PulmCCM Reviews) by Brett Ley, MD Nearly 800,000 patients require mechanical ventilation yearly. There’s no doubt it is a life-saving intervention, but it is one that is fraught with the potential for iatrogenesis, especially if continued for longer than necessary. That is the main message of this review in [... read more]
Fecal Transplants Cure C. difficile Infections, When Drugs Can’t Antibiotics are what cause Clostridium difficile infection to emerge in the first place, so it’s perhaps no surprise that the usual treatment — more antibiotics — often fails. From 15-25% of patients with C. difficile are not permanently cured by their initial treatment with metronidazole, and among those [... read more]
Ultrafiltration No Better Than Diuresis for CHF Exacerbations by Blair Westerly, MD Cardiorenal syndrome — simultaneous heart failure and renal failure — is a frequently encountered problem in people with acute decompensated heart failure. Treatment with diuretics for congestive heart failure exacerbations is standard care, but diuretics may at times worsen renal function. Venovenous ultrafiltration [... read more]
Blood Transfusion: Deadly for GI Bleeds? You read the headline right: in a randomized trial published in the January 3 New England Journal of Medicine, liberal blood transfusions (to a hemoglobin of 9 g/dL) seemed to cause the deaths of people with acute upper gastrointestinal bleeding, as compared to transfusing when hemoglobin fell below 7 [... read more]
Visual learners can see continuous positive airway pressure (CPAP) work for obstructive sleep apnea in realtime in this NEJM video. But how on earth does someone sleep inside an MRI machine? See the Sleep Apnea Video
(image: Wikipedia) As we reported a few months ago, the PANTHER-IPF trial was stopped early for safety, when it became clear that the combination of prednisone and azathioprine was hurting people with idiopathic pulmonary fibrosis (IPF). Ganesh Raghu (U-Washington), Kevin Anstrom (Duke), Talmadge King (UCSF) et al report the final results in the May 24 New [... read more]
(image: Rxhealthdrugs.com) Azithromycin for Prevention of COPD Exacerbations Azithromycin taken daily prevents exacerbations of chronic obstructive pulmonary disease (COPD exacerbations), but seems to also carry risks for cardiovascular death and hearing loss. The true balance of risks and benefits with use of azithromycin to prevent COPD exacerbations is unknown, but physicians who choose to prescribe [... read more]
Daily Inhaled Steroids Stunt Kids’ Growth, Study Shows If you’re a half-inch shy of six feet, the next time you’re getting your jump shot blocked by your non-asthmatic friend, you can blame the inhaled corticosteroids your Mom made you take as a kid. Studies have consistently showed children’s height slows down for a few years [... read more]
Spiriva (Tiotropium) for Uncontrolled Asthma Most people with asthma can achieve good control with inhaled corticosteroids (ICS) and a long-acting beta-agonist (LABA). Some people living with asthma, though, experience persistent symptoms despite maximum doses of these inhaled medications. Fairly or not, LABAs have also been sullied with an FDA black-box warning for worsening bronchospasm in a [... read more]
Hydroxyethyl Starch (Voluven) Causes Kidney Failure In Large Trial Hydroxyethyl starch (HES) was already wearing a scarlet letter as an potentially dangerous volume resuscitation agent for patients in shock, after evidence emerged this year that hydroxyethyl starch kills people with severe sepsis. Now, another huge, convincing trial shows that hydroxyethyl starch (Voluven) damages kidneys and [... read more]
(image: Rxhealthdrugs.com) People taking 5 days of azithromycin had a very small absolute increased risk of death, especially due to cardiovascular causes, compared to people taking amoxicillin, in a retrospective cohort review by Wayne Ray, Katherine Murray, and C. Michael Stein published in the May 17 New England Journal of Medicine. Erythromycin and clarithromycin (the other [... read more]
Recombinant human activated protein C or dotrecogin alfa — better known as Xigris, by Eli Lilly — seemed a godsend when it was first approved for treatment of severe sepsis in 2001. Xigris’ FDA approval (despite an evenly split 10-10 vote) was based solely on the Eli Lilly-funded PROWESS study, a phase 3 randomized trial [... read more]
Xarelto (rivaroxaban): New FDA Indication for DVT, PE The U.S. Food and Drug Administration (FDA) approved Bayer’s Xarelto (rivaroxaban) for a new indication for treating deep vein thrombosis (DVT) or pulmonary embolism (PE), and for long-term prophylaxis of recurrent DVT and PE. Xarelto already had FDA approval for prevention of DVTs and PEs after knee or [... read more]
(image: InPharm) Rivaroxaban (Xarelto) was noninferior to standard treatment (heparin and warfarin) in preventing recurrent VTE in patients with acute pulmonary embolism (PE), in the large EINSTEIN-PE randomized trial published in the April 5 New England Journal of Medicine. A once-daily oral factor Xa inhibitor that has already been demonstrated to be noninferior for treatment [... read more]
(image: Rex Parker) Among people with unprovoked deep venous thrombosis (DVT) or pulmonary embolism (PE), 1 in 5 will experience another DVT or PE within 2 years after stopping anticoagulation with warfarin (Coumadin). For this reason, the ACCP’s recommendations for treatment of unprovoked proximal DVT or PE suggest consideration of an “indefinite” period of anticoagulation [... read more]
We intensivists are a scarce and valuable commodity — just ask us, we’ll tell you. It’s been consistently shown, for example, that involved intensivists in an ICU during the day correlates with improved mortality and efficiencies in care. Now that’s something we can all cheer (ourselves) about. Many intensivists also like to sleep, and may [... read more]
Colloids are believed to be more effective expanders of plasma volume than crystalloids, making them a tempting therapy to use for patients in septic shock and other causes of hemodynamic instability. Problem is, some colloid solutions seem to kill people. The VISEP Trial using hydroxyethyl starch 200 kDa/0.5 demonstrated that this high molecular weight HES [... read more]
