Meta Analysis
Stress ulcer prophylaxis in critically ill patients. Resolving discordant meta-analyses.
To resolve discrepancies in previous systematic overviews and provide estimates of the effect of stress ulcer prophylaxis on gastrointestinal bleeding, pneumonia, and mortality in critically ill patients. ⋯ Our results emphasize the need for registries to include all randomized trials and demonstrate the importance of explicit methodology for systematic reviews. There is strong evidence of reduced clinically important gastrointestinal bleeding with histamine2-receptor antagonists. Sucralfate may be as effective in reducing bleeding as gastric pH-altering drugs and is associated with lower rates of pneumonia and mortality. However, the data are insufficient to determine the net effect of sucralfate compared with no prophylaxis.

Randomized Controlled Trial Clinical TrialMagnesium repletion and its effect on potassium homeostasis in critically ill adults: results of a double-blind, randomized, controlled trial.
The aims of this study were to evaluate the safety and efficacy of magnesium replacement therapy and to determine its effect on potassium retention in hypokalemic, critically ill patients. ⋯ Magnesium sulfate administered according to the above regimen safety and significantly increases the circulating magnesium concentration. Despite greater urine magnesium losses in the treatment group, this group exhibited significantly better magnesium retention.

To determine whether scoring on the Acute Physiology and Chronic Health Evaluation (APACHE) III at admission can predict the development of multiple organ dysfunction syndrome and mortality in critically ill surgical patients. ⋯ The development of multiple organ dysfunction syndrome correlated with higher APACHE III scores but was independent of the type of perforation. Only the development of overt multiple organ failure predicted death. Combined use of APACHE III and the multiple organ dysfunction score provides improved prediction of multiple organ dysfunction syndrome, but further enhancements are needed before prediction of outcome in individual patients is reliable.
