The primary aim was to measure the amount of nutrients required, prescribed and actually administered in critically ill patients. Secondary aims were to assess adherence to clinical practice guidelines, and investigate factors leading to non-adherence. ⋯ The translation of clinical research and recommendations for enteral nutrition into routine bedside practice in critically ill patients receiving mechanical ventilation was satisfactory, but could probably be improved with a multidisciplinary approach.

Comparative Study
Delirium as a predictor of sepsis in post-coronary artery bypass grafting patients: a retrospective cohort study.
Delirium is the most common neurological complication following cardiac surgery. Much research has focused on potential causes of delirium; however, the sequelae of delirium have not been well investigated. The objective of this study was to investigate the relationship between delirium and sepsis post coronary artery bypass grafting (CABG) and to determine if delirium is a predictor of sepsis. ⋯ These data demonstrate an association between delirium and post-operative sepsis in the CABG population. Delirium emerged as an independent predictor of sepsis, along with traditional risk factors including age, pre-operative renal failure and peripheral vascular disease. Given the advancing age and increasing rates of delirium in the CABG population, the prevention and management of delirium need to be addressed.

Randomized Controlled Trial Comparative Study
Central venous O₂ saturation and venous-to-arterial CO₂ difference as complementary tools for goal-directed therapy during high-risk surgery.
Central venous oxygen saturation (ScvO2) is a useful therapeutic target in septic shock and high-risk surgery. We tested the hypothesis that central venous-to-arterial carbon dioxide difference (P(cv-a)CO2), a global index of tissue perfusion, could be used as a complementary tool to ScvO2 for goal-directed fluid therapy (GDT) to identify persistent low flow after optimization of preload has been achieved by fluid loading during high-risk surgery. ⋯ ScvO2 reflects important changes in O2 delivery in relation to O2 needs during the perioperative period. A P(cv-a)CO2 < 5 mmHg might serve as a complementary target to ScvO2 during GDT to identify persistent inadequacy of the circulatory response in face of metabolic requirements when an ScvO2 ≥ 71% is achieved.

Meta Analysis Comparative Study
Effect of histamine-2-receptor antagonists versus sucralfate on stress ulcer prophylaxis in mechanically ventilated patients: a meta-analysis of 10 randomized controlled trials.
We conducted a meta-analysis in order to investigate the effect of histamine-2-receptor antagonists (H2RA) versus sucralfate on stress ulcer prophylaxis in mechanically ventilated patients in the intensive care unit (ICU). ⋯ In patients with mechanical ventilation, H2RA resulted in no differential effectiveness in treating overt bleeding, but had higher rates of gastric colonization and ventilator-associated pneumonia. Additional RCTs of stress ulcer prophylaxis with H2RA and sucralfate are needed to establish the net benefit and risks of adverse effect in mechanically ventilated patients.
