Differences in acid-base behavior between intensive care unit survivors and nonsurvivors using both a physicochemical and a standard base excess approach: a prospective, observational study.
This study aimed to test the hypothesis that intensive care unit survivors and nonsurvivors differ with regard to type and severity of acid-base disorders. ⋯ Intensive care unit survivors and nonsurvivors differed in the severity of metabolic acidosis; however, the proportion of the different anions causing the acidosis on admission was similar between these 2 groups.

Work of breathing during successful spontaneous breathing trial.
The aim of this study was to evaluate the work of breathing (WOB) behavior during a 120-minute successful spontaneous breathing trial (SBT) with T-tube trial, and its predictive value for extubation outcome. ⋯ An increase in the WOB could predict extubation failure during a T-tube trial of 120 minutes.

Delirium recognition and sedation practices in critically ill patients: a survey on the attitudes of 1015 Brazilian critical care physicians.
The aim of the study was to characterize the practices of Brazilian ICU physicians toward sedation and delirium. ⋯ Despite the recent advances in knowledge of sedation and delirium, most of them are still not translated into clinical practice. Significant variation in practice is observed among ICU physicians and represents a potential target for future research and educational interventions.

Assessing the predictive value of the bispectral index vs patient state index on clinical assessment of sedation in postoperative cardiac surgery patients.
To compare the depth of sedation determined by Ramsay sedation scale (RSS) with electroencephalogram-based bispectral index (BIS) and patient state index (PSI). ⋯ There is significant positive correlation between the BIS and PSI but poor correlation and poor test agreement between the RSS and BIS as well as RSS and PSI. The BIS is a better predictor of oversedation compared with the PSI. There was no significant difference between the BIS and PSI with respect to the prediction of undersedation.

Prognosis and 1-year mortality of intensive care unit patients with severe hepatic encephalopathy.
Data regarding outcome of patients with chronic liver disease with severe hepatic encephalopathy in intensive care unit are currently scarce. ⋯ Predictors of outcome were similar to other groups of patients with liver disease admitted for other reasons. Intensive care unit mortality was lower than reported for other groups of patients with similar illness. Patients with severe HE admitted to ICU with no organ dysfunction other than mechanical ventilation had a better outcome and may require ICU admission.
