[Hyperlactatemia at ICU admission is a morbid-mortality determinant in high risk non-cardiac surgeries].

Background And Objectives: One of the greatest challenges found by the intensivists in their daily activities is tissue hipoperfusion control. Blood lactate is generally accepted as a marker of tissular hypoxia and several studies have demonstrated good correlation between blood lactate and prognosis during shock and resuscitation. The aim of this study was to evaluate the clinical utility of arterial blood lactate as a marker of morbidity and mortality in critically ill patients in the post-operative period of high risk non-cardiac surgeries.

[Cancer disease should not be a limitative factor for admission of high risk surgical patients to an intensive care unit].

Background And Objectives: Oncologic diseases are conditions that have influence in the treatment offered to affected patients. The aim of this study was to compare hospitalar outcome of oncologic and non oncologic patients submitted to high risk elective surgery.

Methods: Prospective, observational cohort study realized in an ICU of a tertiary hospital during the period between 04/01/2005 and 07/31/2005.
