A minimum blood glucose value less than or equal to 120 mg/dL under glycemic control is associated with increased 14-day mortality in nondiabetic intensive care unit patients with sepsis and stress hyperglycemia.
Hyperglycemia is common in critically ill patients, but results of previous trials on glycemic control have been controversial. This study aimed to investigate whether the minimum blood glucose value during the first 72 hours after admission (72-min-BGV) was associated with mortality in patients with severe sepsis. ⋯ A 72-min-BGV less than or equal to 120 mg/dL was an independent risk factor for 14-day mortality in nondiabetic patients with hyperglycemia admitted to our intensive care unit due to severe sepsis, but not in diabetic patients under the same setting.

End-of-life care in the intensive care unit: Report from the Task Force of World Federation of Societies of Intensive and Critical Care Medicine.
End-of-life care in the intensive care unit (ICU) was identified as an objective in a series of Task Forces developed by the World Federation of Societies of Intensive and Critical Care Medicine Council in 2014. The objective was to develop a generic statement about current knowledge and to identify challenges relevant to the global community that may inform regional and local initiatives. ⋯ The complexity of end-of-life care in the ICU, particularly relating to withholding and withdrawing life-sustaining treatment while ensuring the alleviation of suffering, within different ethical and cultural environments is recognized. Although no single statement can therefore be regarded as a criterion standard applicable to all countries and societies, the World Federation of Societies of Intensive and Critical Care Medicine endorses and encourages the role of Member Societies to lead the debate regarding end-of-life care in the ICU within each country and to take a leading role in developing national guidelines and recommendations within each country.

ReviewTime to loss of brain function and activity during circulatory arrest.
Brain function during the dying process and around the time of cardiac arrest is poorly understood. To better inform the clinical physiology of the dying process and organ donation practices, we performed a scoping review of the literature to assess time to loss of brain function and activity after circulatory arrest. ⋯ The time required to lose brain function varied according to clinical context and method by which this function is measured. Most studies show that clinical loss of consciousness and loss of EEG activity occur within 30seconds after abrupt circulatory arrest and may occur before circulatory arrest after progressive hypoxia-ischemia. Prospective clinical studies are required to confirm these observations.

Comparative StudyComparison between respiratory changes in the inferior vena cava diameter and pulse pressure variation to predict fluid responsiveness in postoperative patients.
The objective of our study was to assess the reliability of the distensibility index of the inferior vena cava (dIVC) as a predictor of fluid responsiveness in postoperative, mechanically ventilated patients and compare its accuracy with that of the pulse pressure variation (PPV) measurement. ⋯ The individual PPV discriminative properties for predicting fluid responsiveness in postoperative patients seemed superior to those of dIVC.
