ICM year in review: respiratory, cardiodynamics and renal

This first session of the day in room Lisbon was a rapid run through of the journals’ most important papers of the last year  – a bumper year as the journals impact factor has soared.

Some notes below:

Respiratory papers

IC-GLOSSARI, the Intensive Care Global Study on Severe Acute Respiratory Infection which was a great ESICM project led by Yasser Sakr and is described as “a multicenter, multinational, 14-day inception cohort study”, in which I admit a COI in that i was involved on one of the sites, but a good paper in that it crossed continents and showed that admission to the ICU for severe lung infection is not only common but also associated with high morbidity and mortality rates.

ECMO epidemiology, this German study showed an increase in ECMO use especially amongst more elderly patients, since 2007.  VV ECMO seems to have reached a “plateau” in use. Mortality has decreased over time – the authors attribute this to experience – but is still stunningly high –  58 and 66 % for vv-ECMO and va-ECMO respectively.

ARDS rehabilitation – Pfoh and colleagues examined “physical declines occurring after hospital discharge” in people who survive ARDS and followed up patients for 5 years.  The headline is that most people decline, and older people and those with co-morbidities decline more.

Lung US training – This paper followed 11 respiratory therapists who had never used ultrasound before over 9 months and claims that 12 scans is the magic number to attain competence.  The jury is out…

The TRACHUS trial looked at ultrasound for tracheostomy – a good idea surely.  Anyway the paper says that it is safe and useful.  As @PhilMcglone said in his review for The Bottom Line – Why choose between bronchoscopy and ultrasound when we can use both?

Finally in the respiratory section this directions-type paper from Jeremy Beitler and the ARDSnet group (now ARDSne(x)t – see what they did there…) on personalising ARDS treatment. The research agenda is going to ask simultaneously both “whether a treatment affords clinically meaningful benefit and for whom.” Watch this space. Or read the paper:

Cardiodynamics and Ultrasound

Antoine Vieillard-Baron discussed the most important papers from this excitingly titled topic.

The FENICE trial was another landmark “global inception cohort study” and looked at fluid management and fluid boluses ( et al).  It showed massive variation in what a fluid bolus is and how it is used.  The question posed by AVL was why did only 2% of physicians use echo to manage fluid? Not enough trainers? Too difficult? Maurizio himself weighed in on the twitter chat below:

Then a study from 3 countries on point of care ultrasound use was presented.  Adrian has reviewed it nicely here for the NEXT journal club – or read the paper.  POCUS is underused generally, and only half the CVC insertions were performed under US guidance.

Finally a nice review article (authored by the presenter) on how to use ultrasound in ventilation management – 4 key areas:

  1. Assessment of cardiac function
  2. Assessment of diaphragmatic function
  3. Assessment of lung function
  4. Identification of pleural effusion

Kidneys

Matt wrote a nice blog on this yesterday, so briefly some of the papers discussed today were:

Statins in heart valve surgery

The kidney injury epidemiology study (AKI-EPI)

http://link.springer.com/article/10.1007%2Fs00134-015-3934-7

And the Truche study – looking again at continuous vs intermittent RRT:
