Post-pyloric feeding no better than usual NG tube in vented patients (RCT)

Image: EIMJM.com Evidence-based practice guidelines adopted by critical care societies in Canada, Germany, Australia and New Zealand recommend starting enteral nutrition for critical illness shortly after admission to an ICU. In observational studies, critically ill adults get only about 50-70% their caloric goals from enteral feeding; reduced gastric motility is often responsible for the limited [… read more]

Superior Vena Cava Syndrome Review

Superior Vena Cava Syndrome: A Cancer-Related Medical Emergency (More PulmCCM Topic Updates) Multiple cancers are expected to rise in prevalence in the U.S. over the coming decades, and so is the risk for cancer-related medical emergencies. For a few, superior vena cava syndrome (SVC syndrome) will be the first manifestation of their cancer. It’s important [… read more]

Cancer-Related Medical Emergencies: Tumor Lysis Syndrome

Cancer-Related Medical Emergencies: Acute Tumor Lysis Syndrome (More PulmCCM Topic Updates) The prevalence of multiple cancers are expected to rise in the United States over the coming decades. Despite improved survival with some cancers, some people with malignancy will develop cancer related emergencies; for a few, this will be the first manifestation of their cancer. [… read more]

GM-CSF (Leukine) for acute lung injury & ARDS (RCT)

Human recombinant granulocyte macrophage colony stimulating factor (GM-CSF or Leukine) did not reduce ventilator-days in patients with acute lung injury / ARDS in a randomized trial published in the January 2012 Critical Care Medicine. Why would it have? Interestingly, patients with ARDS with higher levels of GM-CSF in their BAL fluid are more likely to survive. GM-CSF maintains [… read more]

Blood pressure cuffs vs arterial lines for hypotensive patients

If you and your team just can’t get an arterial line into your critically ill, hypotensive patient for continuous invasive blood pressure measurement, you may be somewhat comforted by the findings of Karim Lakhal, Christine Macq, Xavier Capdevila et al in the April 2012 Critical Care Medicine. They found that among 150 critically ill patients [… read more]

For some LTAC patients, pessimism is the new kindness

(image: flickrCC) Half of patients transferred to long-term acute care facilities (LTACs) on prolonged mechanical ventilation will die within a year, according to a 2010 review. Only a small minority will ever go home without needing significant caregiver assistance. For those over age 65, the prognosis is even worse. It seems rude, or even cruel, [… read more]

Where's the respect (and $$) for critical care research?

(image: Suburban Wino) Craig Coopersmith of Emory is an amazing guy and a prolific investigator in critical care — and it looks like he’s fed up with having his grants rejected. After some epic bean-counting, his group concludes that critical care research gets short shrift in federal research funding, compared to the huge amounts spent [… read more]

Do you have cooties? MDR-bug transmission rates in ICUs (Crit Care Med)

(image: flickrCC) Foam in, foam out, gown on, gown off … ah, the tedium of practicing critical care medicine in the age of rampant, lethal, multi-drug resistant bacteria. As a reminder to keep your guard up and your gear on, here’s a yucky study from Daniel Morgan, Elizabeth Rogawski, and Anthony Harris of the University [… read more]

An observational trial by Jim Kutsoguiannis, Cathy Alberda, Daren Heyland et al published in the December 2011 Critical Care Medicine showed no difference in 60-day survival among critically ill, mechanically ventilated patients started on parenteral nutrition (TPN) “early” (within 48 hours of ICU admission) or “late” (after 48 hours). Only 258 patients were included in the [… read more]

Webb and Samuels (Emory neuro-intensivists) report on a brain-injured patient who, after induced hypothermia and rewarming, had absent brainstem function and a confirmatory apnea test. However, in the O.R. for organ donation 24 hours later, brainstem function transiently returned and the surgery had to be aborted. They urge caution to the rest of us in [… read more]

It's official -- Someone's being too negative (Crit Care Med)

ICU Prognosis is Easy, Except When It’s Not How accurate are predictions of mortality by ICU team members? For 560 consecutive patients admitted to a single MICU at the University of Chicago, the authors polled the patient’s attending, fellow, resident, and nurse privately each day, asking simply: “Will this patient survive to discharge?” They collected [… read more]

Several favorable randomized trials and a meta-analysis have suggested procalcitonin is a reliable and useful biomarker of infection, including in the ICU. In contrast, Jensen et al report use of a procalcitonin-driven algorithm to guide antimicrobial therapy in 9 ICUs in Denmark seemed to cause a bit of harm. They randomized 1,200 patients to either [… read more]

Muscedere J. Subglottic secretion drainage for the prevention of ventilator-associated pneumonia: A systematic review and meta-analysis. Crit Care Med 2011;39:1985-1991. In short, it probably works to prevent ventilator-associated pneumonia (13 randomized trials, n=2,442. 12 were positive, pooled risk ratio 0.55, associated with 1-1.5 shorter days in the ICU and on the ventilator). So why not use [… read more]

For 10 years, Zahar et al prospectively observed 3,588 patients developing severe sepsis & septic shock who ended up in French ICUs. Their sample captured a broad array of infections acquired in the community, the hospital ward, or the ICU (about 1/3 each). After multivariate assessment, they could not find an independent influence on mortality [… read more]

Johnson et al reviewed charts in a retrospective case-control cohort study on 754 consecutive patients at Barnes-Jewish with severe sepsis or shock due to Gram-negative bacteremia. The exposure was receipt of antibiotics in the previous 90 days. 310 of the bacteremic patients had received antibiotics previously. Compared to unexposed controls, the previously antibiotic-exposed had a [… read more]

3% saline infusions have become standard care for increased intracranial pressure at many centers, based on mostly anecdotal evidence. Hauer et al looked retrospectively at 100 patients receiving 3% saline for severe stroke in 2008-2009 (intracerebral hemorrhage, subarachnoid hemorrhage, or ischemic) and compared them to 115 historical controls, 2007-2008 with “equal” underlying disease. Hypertonic saline [… read more]

Fragou et al randomized 401 ICU patients to undergo subclavian vein central line placement with guidance either by ultrasound or anatomic landmarks. All cannulations were with an infraclavicular approach. The ultrasound group had a higher success rate (100% vs 87.5%), shorter time to access and fewer number of attempts, and a lower rate of complications. [… read more]

Stapleton et al report results of a phase II trial of 14 days of omega-3 fish oil vs. placebo in 90 people with acute lung injury or ARDS. There was no difference in the primary endpoint (inflammatory marker IL-8 in BAL fluid), nor in any clinical outcome. Crit Care Med 2011;39:1655-1662.
