Sedation in French intensive care units: a survey of clinical practice.
Sedation is used frequently for patients in intensive care units who require mechanical ventilation, but oversedation is one of the main side effects. Different strategies have been proposed to prevent oversedation. The extent to which these strategies have been adopted by intensivists is unknown. ⋯ Despite a low individual response rate, the respondents to our survey represent almost half of the ICUs in the French SRLF database. The presence of a written local sedation procedure, a cornerstone of preventing oversedation, is reported by only half of respondents; when present, it is used in for a limited number of patients. Sedation procedures mainly rely on titration of continuous IV hypnotics, but other strategies to limit oversedation also are included in sedation procedures. French intensivists no longer consider severely altered consciousness a sedation objective for most patients.

Propofol infusion syndrome resuscitation with extracorporeal life support: a case report and review of the literature.
We report a case of propofol infusion syndrome (PRIS) in a young female treated for status epilepticus. In this case, PRIS rapidly evolved to full cardiovascular collapse despite aggressive supportive care in the intensive care unit, as well as prompt discontinuation of the offending agent. ⋯ She regained a perfusing rhythm after prolonged (>8 hours) asystole, was weaned off ECMO and eventually all life support, and was discharged to home. We also present a review of the available literature on the use of ECMO for PRIS.

Comparison of thermodilution measured extravascular lung water with chest radiographic assessment of pulmonary oedema in patients with acute lung injury.
Acute lung injury and the acute respiratory distress syndrome (ALI/ARDS) are characterized by pulmonary oedema, measured as extravascular lung water (EVLW). The chest radiograph (CXR) can potentially estimate the quantity of lung oedema while the transpulmonary thermodilution method measures the amount of EVLW. This study was designed to determine whether EVLW as estimated by a CXR score predicts EVLW measured by the thermodilution method and whether changes in EVLW by either approach predict mortality in ALI/ARDS. ⋯ EVLW measured by CXR was modestly correlated with thermodilution measured EVLW. Unlike CXR findings, transpulmonary thermodilution EVLWI measurements over time predicted mortality in patients with ALI/ARDS.

How caregivers view patient comfort and what they do to improve it: a French survey.
Intensive care unit (ICU) patients are exposed to many sources of discomfort. Most of these are related to the patient's condition, but ICU design or how care is organized also can contribute. The present survey was designed to describe the opinions of ICU caregivers on sources of patient discomfort and to determine how they were dealt with in practice. The architectural and organizational characteristics of ICUs also were analyzed in relation to patient comfort. ⋯ Results of this survey showed that ICUs are poorly equipped to ensure patient privacy and rest. Access by loved ones and their participation in care also is limited. The data also highlighted that some sources of discomfort are less often taken into account by caregivers, despite being considered to contribute significantly.

Pharmacological interventions in acute respiratory distress syndrome.
Pharmacological interventions are commonly considered in acute respiratory distress syndrome (ARDS) patients. Inhaled nitric oxide (iNO) and neuromuscular blockers (NMBs) are used in patients with severe hypoxemia. No outcome benefit has been observed with the systematic use of iNO. ⋯ In patients with persistent ARDS after 7 to 28 days, a randomized trial showed no reduction in mortality with moderate doses of corticosteroids but an increased PaO2 to FiO2 ratio and thoracopulmonary compliance were found, as well as shorter durations of mechanical ventilation and of ICU stay. Conflicting data exist on the interest of low doses of corticosteroids (200 mg/day of hydrocortisone) in ARDS patients. In the context of a persistent ARDS with histological proof of fibroproliferation, a corticosteroid treatment with a progressive decrease of doses can be proposed.
