Right over left ventricular end-diastolic area relevance to predict hemodynamic intolerance of high-frequency oscillatory ventilation in patients with severe ARDS.
High-frequency oscillatory ventilation (HFOV) does not improve the prognosis of ARDS patients despite an improvement in oxygenation. This paradox may partly be explained by HFOV hemodynamic side-effects on right ventricular function. Our goal was to study the link between HFOV and hemodynamic effects and to test if the pre-HFOV right over left ventricular end-diastolic area (RVEDA/LVEDA) ratio, as a simple parameter of afterload-related RV dysfunction, could be used to predict HFOV hemodynamic intolerance in patients with severe ARDS. ⋯ The RVEDA/LVEDA ratio measured just before HFOV predicts the hemodynamic intolerance of this technique in patients with severe ARDS. A high ratio under CMV raises questions about the use of HFOV in such patients.

Acute respiratory failure in patients with hematological malignancies: outcomes according to initial ventilation strategy. A groupe de recherche respiratoire en réanimation onco-hématologique (Grrr-OH) study.
In patients with hematological malignancies and acute respiratory failure (ARF), noninvasive ventilation was associated with a decreased mortality in older studies. However, mortality of intubated patients decreased in the last years. In this study, we assess outcomes in those patients according to the initial ventilation strategy. ⋯ gov number NCT 01172132.

Continuous control of tracheal cuff pressure for VAP prevention: a collaborative meta-analysis of individual participant data.
Underinflation of tracheal cuff is a risk factor for microaspiration of contaminated secretions and subsequent ventilator-associated pneumonia (VAP). The aim of this collaborative meta-analysis of individual participant data is to determine the impact of continuous control of P cuff on the incidence of VAP. ⋯ Continuous control of P cuff might be beneficial in reducing the risk for VAP. However, no significant impact of continuous control of P cuff was found on duration of mechanical ventilation, ICU length of stay, or mortality.

Influence of in-line microfilters on systemic inflammation in adult critically ill patients: a prospective, randomized, controlled open-label trial.
In critically ill children, in-line microfilters may reduce the incidence of the systemic inflammatory response syndrome (SIRS), the overall complication and organ dysfunction rate. No data on the use of in-line microfilters exist in critically ill adults. ⋯ The use of in-line microfilters failed to modulate systemic inflammation and clinical outcome parameters in critically ill adults.

Withholding or withdrawal of treatment under French rules: a study performed in 43 intensive care units.
In France, decisions to limit treatment fall under the Leonetti law adopted in 2005. Leading figures from the French world of politics, science, and justice recently claimed for amendments to the law, considering it incomplete. This study, conducted before any legislative change, aimed to investigate the procedural aspects of withholding/withdrawing treatment in French ICUs and their adequacy with the existing law. ⋯ More than half of deaths in the study population occurred after a decision to withhold or withdraw treatment. Among patients under withholding/withdrawal procedures, brain-injured subjects were more likely to undergo a withdrawal procedure. The prevalence of advance directives and designated trusted persons was low. Because patients' preferences were unknown in more than three quarters of cases, decisions remained primarily based on medical judgment. Limitations, especially withholding of treatment, did not preclude survival and hospital discharge.
