Randomized Controlled Trial Multicenter Study Comparative Study
Statistical analysis plan for the Crystalloid Versus Hydroxyethyl Starch Trial (CHEST).
The Crystalloid Versus Hydroxyethyl Starch Trial (CHEST) is a 7000-patient, multicentre, randomised controlled trial comparing the effects of 6% hydroxyethyl starch (130/0.4) to normal saline for fluid resuscitation in intensive care patients. The trial design is based on the Saline Versus Albumin Fluid Evaluation (SAFE) study and will be the largest fluid resuscitation trial conducted to date. ⋯ We have developed a predetermined SAP for CHEST. This plan accords with high-quality standards of internal validity to minimise analysis bias.

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.

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.

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.
