Multicenter StudyReview of a large clinical series: association of cumulative fluid balance on outcome in acute lung injury: a retrospective review of the ARDSnet tidal volume study cohort.
To evaluate the independent influence of fluid balance on outcomes for patients with acute lung injury. ⋯ Negative cumulative fluid balance at day 4 of acute lung injury is associated with significantly lower mortality, independent of other measures of severity of illness.

Dysfunction of the vascular endothelium (ET) causes an increase in serum ET-1 concentration, as observed in septic patients. It was assumed that in this patient population the ET-1 level correlates with the degree of sepsis severity, including the level of organ dysfunction and, in particular, the level of circulatory dysfunction. The aim of the present study was to assess the relationship between levels of ET-1 and levels of N-terminal brain natriuretic propeptide (NT-proBNP), procalcitonin (PCT), and C-reactive protein (CRP), as well as the Sepsis-related Organ Failure Assessment (SOFA) score in septic patients. ⋯ Correlation between the ET-1 levels and SOFA score was .470 (P < .001). Six patients (30%) died during the observation period of 28 days. ET-1 levels correlate with levels of NT-proBNP, PCT, and CRP, as well as the SOFA score in septic patients.

Multicenter StudyBlood transfusion policy among European pediatric intensive care physicians.
The objective of this study was to define current blood transfusion practices among European pediatric intensive care physicians treating critically ill children. A questionnaire of case scenarios was administered to members of the European Society of Pediatric and Neonatal Intensive Care (ESPNIC). Of the 258 members of the ESPNIC, 134 (51.9%) pediatric intensive care physicians completed the questionnaire. ⋯ Most physicians, 78/128 (60.9%), did not consider the age of the transfused blood an important factor in their decision to transfuse. Of the 106 (79.1%) physicians who detailed their considerations for elevating the threshold for transfusion, 82 (77.3%) gave a general nonspecific indication, 47 (44.3%) stated hemodynamic instability and shock, and 40 (37.7%) an ongoing bleeding. The hemoglobin threshold for blood transfusion and transfusion volume varies among European pediatric intensive care physicians, for the same patient.

Randomized Controlled Trial Multicenter Study Clinical TrialThe role of the alpha2-adrenoceptor agonist dexmedetomidine in postsurgical sedation in the intensive care unit.
Dexmedetomidine was evaluated for sedation of 401 post-surgical patients in this double-blind, randomized, placebo-controlled, multicenter trial. Dexmedetomidine or saline was started on arrival in the intensive care unit (ICU) (1.0 mcg/kg for 10 minutes), then titrated at 0.2 to 0.7 mcg/kg/h to effect. Patients could be given propofol if necessary. ⋯ The majority of dexmedetomidine patients maintained blood pressures within normal range, without rebound. Hypertension, atelectasis, and rigors occurred more frequently in the control group, while hypotension and bradycardia occurred more frequently in the dexmedetomidine group. Preoperative cardiovascular conditions were not risk factors for dexmedetomidine patients.
