[ICU-acquired neuromyopathy, delirium and sedation in intensive care unit].
ICU-acquired neuromyopathy (NMAR) and delirium are the two most frequent and severe neurological complications of intensive care medicine. Their mechanisms still remain to be elucidated. The objective of this review is to address the potential role of sedation in occurrence of these complications. ⋯ The relationship between delirium and sedation are controversial because in most studies, patients were considered delirious though being still sedated and multivariate analysis was lacking. One study showed that lorazepam given continuously was an independent risk factor for daily transition to delirium 24 h later with a 20% increase risk of every unit dose (expressed as log(e)mg). The impact of deepness, daily interruption or titration of sedation on the prevalence of delirium has never been assessed but it seems that deep sedation has to be avoided.

Case Reports[Resuscitation after three hours of cardiac arrest with severe hypothermia following a toxic coma].
We report the case of a 37-year-old woman who survived from severe hypothermia (rectal temperature: 22 degrees C) and prolonged cardiac arrest with asystole after benzodiazepine and tricyclic antidepressant poisoning. Basic-cardiopulmonary resuscitation and mechanical ventilation was started by a French Mobile Intensive-Care unit. ⋯ The patient was discharged at day 13 without any neurological deficit. The discussion focuses on the benefit of extracorporeal-membrane oxygenation (ECMO) as extracorporeal circulation device through femoral access, the differential diagnosis between death and recoverable cardiac arrest and neuroprotection.

Impact of the use of propofol remifentanil goal-directed sedation adapted by nurses on the time to extubation in mechanically ventilated ICU patients: the experience of a French ICU.
Inappropriate sedation could prolong the duration of mechanical ventilation. The present "before-after" study assessed the impact of a goal-directed sedation using an algorithm with a combination of propofol and remifentanil on the time to extubation. ⋯ Sedation with adapted infusions of propofol and remifentanil according to the Ramsay score and a pain scale decreases the time to extubation in ICU patients requiring sedation longer than 24h but increases the rate of self-extubations.

Case ReportsPrevious safe administrations of neuromuscular blocking agents do not exonerate from the risk of anaphylactic shock.
We describe a grade IV anaphylactic shock to atracurium. A 34-year-old woman was scheduled for her ninth abdominal surgery. Within the last 10 months, for previous abdominal procedures she had received atracurium, cisatracurium or suxamethonium. ⋯ Anaphylaxis was immediately evoked and treatment started. The diagnosis of anaphylaxis to atracurium was confirmed by the allergological assessment. This case report highlights the fact that patients without any previous adverse events to neuromuscular blocking agents are never exempt from risk of anaphylactic shock, even with a designated low-risk agent of sensitization.
