This study sought to identify and describe the clinical and behavioural components (e.g. the what, how, when, where and by whom) of 'selective decontamination of the digestive tract' (SDD) as routinely implemented in the care of critically ill patients. ⋯ This study is the first to formally outline the full spectrum of clinical and behavioural aspects of SDD. It identified points in the delivery process where complex behaviours occur and outlined how SDD can be interpreted and applied variably in practice. This comprehensive specification allows greater understanding of how this intervention could be implemented in units not currently using it, or replicated in research studies. It also identified strategies required to adopt SDD and to standardise its implementation.

High flow nasal cannula is an emerging treatment option in Paediatric Intensive Care Units for paediatric patients in acute respiratory distress. Yet there is a paucity of literature describing its clinical application in various presenting pathophysiologies. ⋯ High flow nasal cannula therapy is a viable treatment option for a range of patients presenting to the Paediatric Intensive Care Unit with acute respiratory distress. More invasive methods of respiratory support may be avoided by the use of high flow nasal cannula therapy.

Review Meta Analysis
Intravenous magnesium therapy in adult patients with an aneurysmal subarachnoid haemorrhage: a systematic review and meta-analysis.
The value of magnesium for the prevention of cerebral arterial vasospasm in patients with aneurysmal subarachnoid haemorrhage (SAH) is debatable. We performed a systematic review to collate the available evidence to evaluate the effects of intravenous magnesium for the prevention of cerebral arterial vasospasm. ⋯ We identified a benefit in the role of magnesium to reduce the incidence of cerebral vasospasm in patients with an aneurysmal SAH. However no benefit was found regarding improved favourable functional outcome or a reduction of mortality.

Considering that the incidence of fever may reach up to 75% among critically ill adults, healthcare professionals employed in the Intensive Care Unit (ICU) are called to evaluate and manage patient temperature elevation on a daily basis. This literature review synthesizes the evidence about the effects of fever and antipyretic treatment in ICU patients. Although the febrile response acts protectively against infections, noxious effects are possible for patients with cerebral damage, neuropsychiatric disorders or limited cardiorespiratory reserve. ⋯ However, fever suppression and return to normothermia improved outcomes of septic shock patients. Antipyretic treatment should begin with drug administration and proceed with external cooling in case of refractory fever, but adverse effects of both antipyretic methods should always be considered. This article concludes by providing implications for antipyretic treatment of critically ill adults and suggesting areas for future research.

Despite the use of guidelines to inform practice for pain and sedation management there are few evaluations of the effect of their introduction on clinical practice. Previous evaluations of the protocols and guidelines used to manage pain and sedation in the paediatric intensive care unit (PICU) report increases in pain and sedation medication administration post guideline introduction. In most reported cases the guideline was accompanied by a treatment algorithm. To our knowledge there is no published data on the effect of introducing a guideline without a treatment algorithm on pain and analgesia administration. ⋯ The introduction of a clinical practice guideline for pain and sedation management in PICU contributes to changes in medication administration, use of validated pain assessments, improved documentation of boluses and communication of management plans.
