Assessing the appropriateness of continuing life support is a difficult task for intensive care unit staff. Part of this difficulty relates to prognostic uncertainty and the varying reliability of clinical decisions. Uncertainty about prognosis is quickly recognised by patients and families, and can be a source of mistrust and potential conflict. ⋯ The family conference should develop an agreed plan through shared decision making. The collective wisdom of experienced health care workers with good communication skills and informed patient advocates increases the likelihood of achieving practical certainty and the best decisions. However, greater time and effort seems to be required to improve end-of-life care in the ICU.

Respiratory complications following cervical spinal cord injury are common and are the leading cause of morbidity and mortality after this type of injury. Impaired mechanics of ventilation, poor cough, increased secretions and bronchospasm predispose to atelectasis, pneumonia and exacerbations of respiratory failure. Prolonged mechanical ventilation and tracheostomy are often required. This review discusses the relevant pathophysiology, various ventilatory strategies and timing of tracheostomy, and examines the evidence surrounding physiotherapeutic and pharmacological treatment options.

Randomized Controlled Trial
Increased brain tissue oxygen tension in children with traumatic brain injury using temperature-corrected guided ventilation during prophylactic hypothermia.
To investigate whether ventilatory management using a temperature-corrected (pH-stat) or uncorrected (alpha-stat) blood gas analysis strategy improves brain tissue oxygen tension (PbrO(2)) in children prophylactically treated with moderate hypothermia for traumatic brain injury. ⋯ PbrO(2) may be improved using a pH-stat blood gas management strategy in prophylactic hypothermia for paediatric patients with traumatic brain injury without any clinically relevant increase in ICP.

Paracetamol is one of the commonest medications used worldwide. This review was conceived as a consequence of evaluating the literature in the protocol development of two randomised, controlled clinical trials investigating the safety and efficacy of paracetamol in ICU patients (the HEAT [Permissive HyperthErmiA Through Avoidance of Paracetamol in Known or Suspected Infection in the Intensive Care Unit] study; the Paracetamol After traumatic Brain Injury [PARITY] Study). ⋯ Despite the widespread use of paracetamol in critical illness, there is a paucity of data supporting its utility in this setting. Further research is required to determine how paracetamol should be used in the critically ill.

Comparative Study
Relationship between illness severity scores in acute kidney injury.
In the field of critical care nephrology, recent publications have used different illness severity scoring systems, making outcome comparisons difficult. ⋯ Simple, robust translational formulae can be developed to allow clinicians to compare illness severity of patients with AKI when illness severity is expressed with different scoring systems.
