[Patient's relatives wishes concerning the visiting hours in an intensive care unit].
The present study was aimed at assessing the opinion of the patient's relatives concerning the visiting hours in the ICU. ⋯ Most of the relatives wish for more liberal visiting times without interfering with patient's care.

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.
