Meta AnalysisNutritional support in the critically ill patients. A critical review of the evidence.
Providing nutritional support has become a standard component of managing critically ill patients. While many studies have documented that providing nutritional support can change nutritional outcomes (e.g., amino acid profile, weight gain, nitrogen balance), data are lacking that demonstrate that nutrition actually influences clinically importance endpoints. This article systematically reviews and critically appraises the literature, examining the relationship between nutritional support and infectious morbidity and mortality in the critically ill patient. In addition, evidence-based recommendations are made.

To determine the effect on mortality of rescuscitation with colloid solutions compared with resuscitation with crystalloids. ⋯ This systematic review does not support the continued use of colloids for volume replacement in critically ill patients.

To review the literature addressing use of the pulmonary artery catheter (PAC) to augment oxygen delivery to supranormal levels in critical illness. ⋯ Further research must be performed before a recommendation can be made about goal-oriented hemodynamic intervention utilizing the PAC to augment oxygen delivery to supranormal levels prior to high-risk surgery. PAC-guided hemodynamic intervention to augment oxygen delivery to supranormal values in patients with SIRS-related organ dysfunction from sepsis, trauma, or postoperative complications is not recommended at this time. Carefully designed, multicenter, randomized, controlled trials are needed to establish whether augmenting oxygen delivery improves organ-specific outcomes and survival under each of these circumstances.

Meta AnalysisDoes selective decontamination of the digestive tract reduce mortality for severely ill patients?
To investigate the relationship between baseline risk of death and reduced mortality after selective decontamination of the digestive tract in intensive care unit patients. ⋯ Mortality reduction from selective decontamination of the digestive tract appears related to the mortality risk of patients at the time of study entry. Future trials should consider using baseline risk assessment as part of trial design and outcome 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.
