Propofol is commonly used for sedation of children or adult patients in intensive care unit as an alternative to benzodiazepines for the long-term sedation of mechanically ventiled patient. However, the life-threatening complication of propofol-infusion syndrome (PRIS) may in some case occur. The objective of this article is to review the clinical features, physiopathology and management of PRIS. ⋯ PRIS is a rare and potentially lethal complication, especially if there's no early identification of the syndrome. The physiopathology of PRIS mechanism remains unclear, however a dysfunction of mitochondrial respiratory chain could be involved and potential genetic factor may account. Clinical features consist of arrhythmias, metabolic acidosis, lipemia, rhabdomyolisis, myoglobinuria. PRIS has been described classically in children and adults undergoing a long term infusion with propofol (more than 48 hours) at doses higher than 4 mg/kg per hour. However, it can be observed with lower doses and after shorter duration of sedation. Steroids, vasopressors and low carbohydrate intake act as triggering factors. Early recognition of the syndrome improve patient's outcome. Propofol infusion must be avoided in susceptible patients and another sedative agent should be considered. When using prolonged sedation with propofol, arrhythmia and serum triglyceridemia level should be monitored.

Randomized Controlled Trial Comparative Study[Performance of the glottiscopes: a randomized comparative study on difficult intubation simulation manikin].
We have prospectively compared simulated-difficult tracheal intubation characteristics of four glottiscopes: Airtraq, GlideScope, McGrath, LMA CTrach with that of the conventional Macintosh laryngoscope. ⋯ When difficult airway was simulated on the manikin, the four glottiscopes were superior to the Macintosh laryngoscope to improve laryngeal exposure quality and to reduce duration of tracheal intubation. Airtraq and the LMA CTrach both demonstrated remarkable advantage over GlideScope and McGrath for simulated difficult intubation management.

Review[Low monocytic HLA-DR expression and risk of secondary infection].
The aim of this bibliographic review is to evaluate the usefulness of the measurement of HLA-DR expression on circulating monocytes (mHLA-DR) in predicting the development of nosocomial infections and unfavourable outcome in critically ill patients. ⋯ The monitoring of mHLA-DR expression could be a biomarker to detect ICU patients at high risk of developing secondary nosocomial infections. Those patients could probably benefit of preemptive strategies to prevent these infections.

Multicenter Study[Current use of sedation and analgesia: 218 resuscitations in France services practices survey].
To assess the current use of sedation and analgesia in a large sample of French intensive care units (ICUs) and to define structural characteristics of the units that use a written procedure. ⋯ Although more than two-third of the responding ICUs reported the use of sedation-and-pain-scales, frequency of assessment was low, and objective assessment of pain in the non-communicating patients was extremely uncommon. Similarly, the use of written procedure was low. The use of sedation-analgesia written procedure in an ICU seems strongly influenced by a more global involvement of the ICU in the protocolisation of complex care. These findings support the reinforcement of educational programs.
