Purpose: Two-dimensional-strain echocardiography (2D-strain) is a promising technique for the early detection of myocardial dysfunction. Our study was aimed to assess its feasibility in the intensive care unit (ICU). Our secondary goal was to determine if 2D-strain could predict the patient's outcome.

Methods: Conventional echocardiography and 2D-strain were performed on 64 consecutive patients admitted to our ICU. Using 2D-strain, the longitudinal deformation of the left ventricle was assessed. Feasibility of 2D-strain, diagnosis performance, and 28-day mortality prediction were determined.

Results: 2D-strain measurements could be performed in 77% of our patients. All 2D-strain variables related to ventricular performance were significantly impaired in the patients who died compared with those who survived. Strain global medium was the only independent echocardiographic variable predictor of 28-day mortality rate (odds ratio 0.60; 95% confidence interval 0.43-0.80, p = 0.002).

Conclusions: 2D-strain measurement is feasible in ICU patients, enabling identifying early left ventricle dysfunction. Strain global medium is an independent predictor of 28-day mortality. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 44:368-374, 2016.

Sleep disorders among French anaesthesiologists and intensivists working in public hospitals: a self-reported electronic survey.

Eur J Anaesthesiol 2015 Feb;32(2):132-7

From the Department of Anesthesiology and Intensive Care Medicine, Conception Hospital (ER, VB, LR, KH, CN, JA), the Department of Anesthesiology and Intensive Care Medicine, North Hospital (FA, ML) and the Department of Sleep Medicine, Timone Hospital (MR), Aix Marseille University, Marseille, France (AN).

Background: Sleep disorders can affect the health of physicians and patient outcomes.

Objectives: To determine the prevalence of sleep disorders among French anaesthesiologists and intensivists working in a public hospital.

Design: A cross-sectional survey.

Setting: Anaesthesiologists and intensivists working in French public hospitals.

Main Outcome Measures: Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) was used to assess the degree of excessive daytime sleepiness.

Results: Among 1504 responders, 677 (45%) physicians reported sleep disorders. The independent factors associated with sleep disorders were reporting of sleep disorders [odds ratio (OR) 12.04, 95% CI (95% confidence interval) 8.89 to 16.46], sleep time less than 7 h (OR 8.86, 95% CI 6.50 to 12.20), work stress (OR 2.04, 95% CI 1.49 to 2.83), stress at home (OR 1.77, 95% CI 1.24 to 2.53), anxiolytic use (OR 3.69, 95% CI 2.23 to 6.25), psychotropic drug use (OR 3.91, 95% CI 1.51 to 11.52) and excessive daytime sleepiness (OR 1.81, 95% CI 1.34 to 2.45). Six hundred and seventy-six (44%) responders reported excessive daytime sleepiness during their professional activity. The independent factors associated with excessive daytime sleepiness were female sex (OR 1.86, 95% CI 1.49 to 2.34), tea consumption (OR 1.47, 95% CI 1.14 to 1.91), regular practice of nap (OR 1.68, 95% CI 1.34 to 2.09), stress at home (OR 1.31, 95% CI 1.02 to 1.68), more than four extended work shifts monthly (OR 1.25, 95% CI 1.01 to 1.56) and sleep disorders (OR 1.73, 95% CI 1.31 to 2.29). Reporting sleep disorder duration and a sleep time less than 7 h were the two major risk factors for sleep disorders. Female sex was the major risk factor for excessive daytime sleepiness.

Conclusion: French anaesthesiologists did not report more sleep disorders than the general population, but their alertness is impaired by a factor of two.
