Multicenter Study
Mild hypothermia during advanced life support: a preliminary study in out-of-hospital cardiac arrest.
Induction of mild hypothermia after cardiac arrest may confer neuroprotection. We assessed the feasibility, safety and effectiveness of therapeutic infusion of 2 l of normal saline at 4 degrees C before return of spontaneous circulation during cardiopulmonary resuscitation after out of hospital cardiac arrest. ⋯ We concluded that prehospital induction of therapeutic hypothermia using infusion of 2 l of 4 degrees C normal saline during advanced life support was feasible, effective and safe. Larger studies are required to assess the impact that this early cooling has on neurological outcomes after cardiac arrest.

Combined didactic and scenario-based education improves the ability of intensive care unit staff to recognize delirium at the bedside.
While nurses play a key role in identifying delirium, several authors have noted variability in their ability to recognize delirium. We sought to measure the impact of a simple educational intervention on the ability of intensive care unit (ICU) nurses to clinically identify delirium and to use a standardized delirium scale correctly. ⋯ A simple composite educational intervention incorporating script concordance theory improves the capacity for ICU nurses to screen for delirium nearly as well as experts. Self-reporting by nurses of completion of delirium screening may not constitute an adequate quality assurance process.

Little is known about the mechanisms through which intensivist physician staffing influences patient outcomes. We aimed to assess the effect of closed-model intensive care on evidence-based ventilatory practice in patients with acute lung injury (ALI). ⋯ Patients with ALI cared for in closed model ICUs are more likely to receive lower VT and less likely to receive higher VT, but there were no other differences in measured processes of care. Moreover, the difference in delivered VT did not completely account for the improved mortality observed in closed model ICUs.

Multicenter Study
Acute lung injury and the acute respiratory distress syndrome in Ireland: a prospective audit of epidemiology and management.
The aim of this study was to describe the epidemiology and management of acute lung injury (ALI) and the acute respiratory distress syndrome (ARDS) in Ireland. ⋯ The incidence of ALI/ARDS is high and is associated with significant mortality. Protective lung ventilation is used commonly throughout participating centres. With low tidal volume ventilation, the degree of hypoxaemia is associated with outcome. These data will inform future multicentre clinical trials in ALI/ARDS in Ireland.

Comparative Study
Circuit life span in critically ill children on continuous renal replacement treatment: a prospective observational evaluation study.
One of the greatest problems with continuous renal replacement therapy (CRRT) is early coagulation of the filters. Few studies have monitored circuit function prospectively. The purpose of this study was to determine the variables associated with circuit life in critically ill children with CRRT. ⋯ Circuit life span in CRRT in children is short but may be increased by the use of hemodiafiltration, higher heparin doses, and filters with a high surface area.
