Multicenter Study
The association between early arterial oxygenation and mortality in ventilated patients with acute ischaemic stroke.
There are conflicting data that suggest that hyperoxia may be associated with either worse or better outcomes in patients suffering a stroke. ⋯ We found no association between worst arterial oxygen tension in the first 24 hours in ICU and outcome in ventilated patients with ischaemic stroke.

The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) is emerging as the most frequently used tool for identifying delirium among critically ill patients. ⋯ In our hospital, the CAM-ICU detected delirium less often than unstructured delirium assessments made by qualified intensive care nurses.

To evaluate the effects of nitroglycerin (glyceryl trinitrate) on intestinal microcirculation during endotoxaemic shock. ⋯ In endotoxaemic sheep, low doses of nitroglycerin failed to improve the subtle but persistent villi hypoperfusion that remains present after fluid resuscitation.

The Australian and New Zealand Intensive Care Society (ANZICS) guidelines for the determination of brain death involve clinical testing and/or the use of brain blood flow analysis techniques. Recently, there has been professional and lay discussion regarding the role of brain blood flow analysis in the determination of brain death. ⋯ Two sets of clinical testing is the most common method for determining brain death in Australian and New Zealand ICUs. A minority of units used some form of brain blood flow imaging. Based on these findings, all brain death certification is in accordance with ANZICS guidelines.

To determine the attitudes of critical care clinicians in Australia and New Zealand towards fever management for critically ill patients with sepsis but without neurological injury. ⋯ There is considerable variability in attitudes to fever management with a reported tendency to act to reduce fever in febrile patients with sepsis. There was broad support for a clinical trial of fever management.
