July 15th 2012

 

 

Welcome

Hello

Welcome to the 32nd Critical Care Reviews Newsletter. Every week, now over three hundred clinical and scientific journals are monitored and the most important and interesting research publications in critical care are highlighted. These studies are added to the Current Articles section of the website on a daily basis, as publication occurs. A link to either the full text or abstract, depending on the publishers degree of open access, is attached. Also, links to other important papers, such as guidelines or consensus statements are included. Free review articles from across the medical literature are also highlighted.

It's been a relatively quiet week for research, with no major studies being published, although there is a wide variety of new review articles linked to, including great papers on venothromboembolism prophylaxis in traumatic brain injury and the interesting technique of submental tracheal intubation.

The topic for This Week's Papers is circulatory monitoring, and starts with a review on cardiac output monitoring in today's Paper of the Day. It's an easy way to stay up-to-date with your reading.

If you think a colleague may find this newsletter useful, please send it on. It's entirely free.

 

Research

JAMA:     Coronary Artery Bypass Grafting

Newman et al performed a multi-centre, randomized, placebo-controlled trial investigating acadesine, a first-in-class adenosine-regulating agent, on a composite endpoint of all-cause mortality, nonfatal stroke, or need for mechanical support for severe left ventricular dysfunction in the setting of coronary artery bypass grafting surgery. The trial was stopped for futility after 3080 of the planned 7500 study participants were randomized. There was no difference in the primary outcome {placebo group: 75/1493 (5.0%) versus acadesine group: 76/1493 (5.1%); odds ratio 1.01 [95% CI, 0.73-1.41]} or secondary outcomes.

Anesthesia & Analgesia:     Perioperative Oxygen Therapy

In a follow up of the PROXI study cohort, Meyhoff et al compared the outcomes of1382 of 1386 patients who underwent abdominal surgery a median 2.3 years post randomisation to either 30% or 80% perioperative oxygen therapy. Mortality was significantly increased in the hyperoxia group {159/685 (23.2%) vs 128/701 (18.3%); hazard risk 1.30, 95% CI 1.03 to 1.64, P=0.03). The difference was significant for patients undergoing cancer surgery (HR 1.45; 95% CI, 1.10 to 1.90; P = 0.009) but not for patients undergoing non-cancer surgery (HR 1.06; 95% CI, 0.69 to 1.65; P = 0.79).

Critical Care:     Acute Kidney Injury

In a registry study, Gammelager et al evaluated the mortality risk of acute kidney injury in 30,762 critically ill Danish patients, of which 4,793 (15.6%) had AKI at ICU admission. 30 day mortality, with corresponding hazard ratios relative to non-AKI patients, for patients using the RIFLE classification, were: No AKI - 12.8%,  Risk - 35.5%, HR 1.96 (95% CI 1.80-2.13); Injury - 44.2%, HR 2.60 (95% CI: 2.38-2.85); Failure - 41.0%, HR 2.41 (95% CI: 2.21-2.64). For patients surviving 30 days (n=25,539), 1 year mortality with associated hazard ratios, were: No AKI - 10.7%; Risk - 20.5%, HR 1.33 (95% CI: 1.17-1.51); Injury - 23.8%, HR 1.60 (95% CI: 1.37-1.87); Failure - 23.2%, HR 1.64 (95% CI: 1.42-1.90).
