Review Meta AnalysisEndoscopy versus fluoroscopy for the placement of postpyloric nasoenteric tubes in critically ill patients: A meta-analysis of randomized controlled trials.
Early postpyloric nasoenteric nutrition is considered an accepted method of nutritional support in critically ill patients. Both endoscopy and fluoroscopy placement of postpyloric nasoenteric tubes (PNTs) have the highest percentages of placement success rate. We aimed to evaluate the differences in efficacy and safety between endoscopy and fluoroscopy methods for the placement of PNTs in critically ill patients. ⋯ Endoscopy and fluoroscopy placement of PNTs can be accurately and safely performed in critically ill patients. Endoscopy may be at least equally as safe as fluoroscopy for the placement of PNTs.

ReviewRole of albumin in diseases associated with severe systemic inflammation: Pathophysiologic and clinical evidence in sepsis and in decompensated cirrhosis.
The metabolism of albumin in inflammatory states such as sepsis or major surgery is complex and still not well characterized. Nevertheless, in inflammatory states, albumin synthesis has been observed to increase. By contrast, in decompensated cirrhosis, a disease characterized by systemic inflammation, albumin synthesis by the liver may decrease to 30% to 50% of normal values. ⋯ The discussion regarding the effect of exogenous albumin administration on intravascular volume in inflammatory states should therefore address albumin turnover. To add complexity to our understanding of the effects of albumin, there are many data indicating that the therapeutic action of albumin is mediated not only through the impact on plasma volume expansion but also through a modulatory effect on inflammation and oxidative stress. All these characteristics are relevant to diseases associated with systemic inflammation including sepsis and decompensated cirrhosis.

Clinical impact of pulmonary sampling site in the diagnosis of ventilator-associated pneumonia: A prospective study using bronchoscopic bronchoalveolar lavage.
It is unclear whether ventilator-associated pneumonia (VAP) is actually a bilateral and multifocal process. In addition, the diagnostic role of chest x-ray is under debate. Assuming a low microbiologic concordance between the left and right lungs, the reliability of a single pulmonary sampling becomes questionable. The purpose of this study was to determine whether the choice of the pulmonary sampling area is clinically relevant in the management of VAP. ⋯ In patients with clinically suspected VAP (especially those without purulent secretions or without radiographically documented bilateral infiltrates), quantitative culture of a single BAL sample may provide an incomplete assessment of lung microbiology, without having a relevant impact on the appropriateness of antimicrobial treatment. These findings suggest that single sampling of respiratory secretions, regardless radiographic opacity, seems to be a reliable diagnostic method in the management of VAP.

The prevalence and outcomes of trauma patients requiring an unplanned return to the intensive care unit (ICU) and those initially admitted to a step-down unit or floor and subsequently upgraded to the ICU, collectively termed unplanned ICU (UP-ICU) admission, are largely unknown. ⋯ UP-ICU admission, although infrequent, was associated with significantly greater hospital length of stay, rate of major abdominal surgery, need for mechanical ventilation, and mortality rates than PL-ICU and NO-ICU admission groups.
