[Consequences of obesity in outcomes after cardiac surgery. Analysis of ARIAM registry].

Background And Objetive: Obesity is a disease that affects a large part of the population and has been associated with worse outcomes after cardiac surgery. The aim of our study is to evaluate the consequences of obesity related to postoperative complications, hospital length of stay and mortality.

Methods: Observational, prospective, multicenter study of patients included in ARIAM registry of adult cardiac surgery between March 2008 to March 2011.

[Indications of non-invasive mechanical ventilation: what's the literature evidence?].

The progressive introduction of non-invasive mechanical ventilation (NIMV) in the management of respiratory failure has increased the number of clinical indications and has reduced common complication of conventional mechanical ventilation. Results of the technique are variable depending on the disease that causes the respiratory failure. With the purpose of reviewing studies about the use of NIMV and to report levels of evidence, different scientific societies have elaborated consensus conferences to establish the utility of NIMV in different indications.

Replacement of 24-h creatinine clearance by 2-h creatinine clearance in intensive care unit patients: a single-center study.

Objective: To estimate the usefulness of 2-h creatinine clearance (CrCl) in the ICU and define variables that may reduce agreement.

Design: Prospective study.

Setting: Polyvalent ICU of a university hospital.

Early hemodynamic improvement is a prognostic marker in patients treated with continuous CVVHDF for acute renal failure.

We examined whether hemodynamic improvement after high-flow hemofiltration predicts survival in patients treated with standard continuous renal replacement therapy (CRRT). This was a prospective, observational cohort study of 169 patients, measuring the mean arterial pressure (MAP) and norepinephrine (NE) dosage before and 24 hours after CRRT. Responders were defined as having a 20% reduction in NE dosage or a 20% rise in MAP with no increase in NE, compared with nonresponders.
