Randomized Controlled Trial Multicenter Study Clinical TrialIL-1ra administration does not improve cardiac function in patients with severe sepsis.
The purpose of this study was to investigate the effects of interleukin-1 receptor antagonist (IL-1ra) on myocardial function in septic patients. ⋯ IL-1ra administration has no effect on cardiac function in septic patients.

Gut mucosal atrophy after a short enteral fasting period in critically ill patients.
The purpose of this study was to evaluate the presence of gut mucosal atrophy and changes in mucosal permeability in critically ill patients after a short fasting period. ⋯ We found that a short period of enteral fasting was associated with significant duodenal mucosal atrophy and abnormal gut permeability in critically ill patients.

Influence of epinephrine and norepinephrine on intestinal villous blood flow during endotoxemia.
The objective of this study was to determine the effects of epinephrine and norepinephrine on mucosal villous blood flow in a normotensive model of endotoxemia. ⋯ In this experimental rat model, the catecholamines epinephrine and norepinephrine in a dosage of 0.2 microg.kg(-1).min(-1) neither diminish nor improve mucosal villous blood flow during the early phase of endotoxemia.

Partial liquid ventilation influences pulmonary histopathology in an animal model of acute lung injury.
The aim of this study was to assess the effect of partial liquid ventilation (PLV) and conventional mechanical ventilation (CMV) in the pattern of distribution of lung injury in a rabbit model of acute lung injury. ⋯ PLV is associated with significant attenuation of lung injury, in comparison to CMV. This effect is predominantly due to attenuation of injury in the dependent region of the lung.

A novel approach to monitor tissue perfusion: bladder mucosal PCO2, PO2, and pHi during ischemia and reperfusion.
The purpose of this study is to determine if monitoring urinary bladder PCO2, PO2, and calculated intramucosal pH would be a reliable index of tissue perfusion. ⋯ Monitoring urinary bladder PO2, PCO2, or calculating pHi may provide a simple and reliable means of monitoring tissue perfusion.
