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.

Observational Study
Mechanism of paracetamol-induced hypotension in critically ill patients: a prospective observational cross-over study.
To elucidate the mechanism of hypotension following intravenous administration of paracetamol (acetaminophen) to patients on the Intensive Care Unit. ⋯ Hypotension with intravenous paracetamol in critically ill patients is caused by a reduction of both cardiac output and systemic vascular resistance. We did not demonstrate any relation between haemodynamic changes and antipyretic action of paracetamol. A possibility that cardiac output is reduced with paracetamol might be clinically important.

Survivors of intensive care units (ICUs) commonly present with symptoms of anxiety, depression and post-traumatic stress disorder (PTSD) during recovery. A number of factors have been identified as predictors of these adverse emotional outcomes, but the role of state anxiety during critical illness in the development of these emotional problems remains unknown. ⋯ This study will provide new evidence to improve care during critical illness and reduce adverse outcomes during recovery with the potential to decrease unnecessary suffering, promote comfort and improve long-term recovery.
