Influence of prone position on gastric mucosal-arterial PCO2 gradients.
To evaluate the effects of mechanical ventilation in the prone position on gastric mucosal-arterial PCO2 gradients. ⋯ Mechanical ventilation in the prone position may be affiliated with increased tonometric gastric mucosal-arterial PCO2 gradients depending on the effect on intraabdominal pressure. Measuring intraabdominal pressure and/or gastric mucosal PCO2 via a nasogastric tube therefore may help to detect adverse effects of this ventilatory strategy.

Acute respiratory distress syndrome among trauma patients: trends in ICU mortality, risk factors, complications and resource utilization.
To evaluate trends in mortality and related factors among trauma patients who developed acute respiratory distress syndrome (ARDS). ⋯ Mortality among trauma patients with ARDS declined over the 8 years studied and was associated with less organ failure. This reduction was probably the result of new approaches to mechanical ventilation, renal failure replacement and vasoactive drug therapy.

Multicenter StudyAccuracy of a composite score using daily SAPS II and LOD scores for predicting hospital mortality in ICU patients hospitalized for more than 72 h.
In most databases used to build general severity scores the median duration of intensive care unit (ICU) stay is less than 3 days. Consequently, these scores are not the most appropriate tools for measuring prognosis in studies dealing with ICU patients hospitalized for more than 72 h. ⋯ The new model using SAPS II and LOD and their evolution during the first calendar days has good discrimination and calibration properties. We propose its use for benchmarking and evaluating the over-risk of death associated with ICU-acquired nosocomial infections.

Randomized Controlled Trial Clinical TrialHigh-volume haemofiltration in human septic shock.
To evaluate whether high volume haemofiltration improves haemodynamics and affects serum cytokine and complement concentrations in human septic shock. ⋯ HVHF decreases vasopressor requirements in human septic shock and affects anaphylatoxin levels differently than standard CVVH.
