Multicenter Study Comparative Study
[Non-invasive evaluation of pulmonary artery occlusion pressure in critically ill patients with mechanical ventilation].
To compare the measurements of pulmonary artery occlusion pressure (PAOP) by means of the use a pulmonary artery catheter and those obtained through a formula that relates the systolic artery pressure before and after a Valsalva maneuver. ⋯ The prediction of the PAOP by means of the Valsalva maneuver showed a limited correlation with that obtained by means of the pulmonary artery catheter.

Analyze the utility and safety of MARS therapy applied with the CRRT monitor. ⋯ The MARS system applied by CRRT monitors provide adequate bilirubin clearance percentages and is safe, even in serious patients. Prolongation of the duration of the sessions was not accompanied by an increase in the risk of infection secondary to the albumin contamination.

Intermediate Care Units are forms to provide health care services to potentially critical patients that allow for improved cost-benefit ratio of the care offered by Intensive Medicine Departments. ⋯ Initiating an intermediate care unit depending on an IMD increases its health care capacity and that of the center it gives service to without affecting global mortality.

Glutamine is the most abundant amino acid in the human body and plays an important role in a number of metabolic pathways. Specifically, it is involved in amino acid and nucleotide synthesis, in the tricarboxylic acid cycle and in ureagenesis. Glutamine has been classified as a non-essential amino acid because the body can synthesize it, but under severe clinical conditions, the pool of glutamine is depleted and could be considered as conditionally essential. ⋯ Administration of supplemental glutamine by enteral or parenteral route has produced controversial results. Most of the studies published support the hypothesis that glutamine can change the morbidity-mortality of the critically ill patients. There are unresolved questions related to the dose of glutamine and the best way to administer it, and particularly the subgroups of patients who will really benefit from this treatment.
