Mechanical thrombectomy with solitaire stent retrieval for acute ischemic stroke in a Brazilian population.

Objective: Large vessel occlusion in acute ischemic stroke is associated with low recanalization rates under intravenous thrombolysis. We evaluated the safety and efficacy of the Solitaire AB stent in treating acute ischemic stroke.

Methods: Patients presenting with acute ischemic stroke were prospectively evaluated.

Indirect calorimetry can be used to measure cardiac output in septic patients?

Purpose: The aim of this study was to compare two different cardiac output (CO) monitoring systems based on the thermodilution principle (Thermo-CO) and indirect calorimetry (Fick mixed-CO) in septic patients.

Methods: Prospective study in septic patients admitted in an intensive care unit of a university hospital. Nineteen patients aged on average 45.

13CO2 recovery fraction in expired air of septic patients under mechanical ventilation.

The continuous intravenous administration of isotopic bicarbonate (NaH13CO2) has been used for the determination of the retention of the 13CO2 fraction or the 13CO2 recovered in expired air. This determination is important for the calculation of substrate oxidation. The aim of the present study was to evaluate, in critically ill patients with sepsis under mechanical ventilation, the 13CO2 recovery fraction in expired air after continuous intravenous infusion of NaH13CO2 (3.

Correlation between oxygen consumption calculated using Fick's method and measured with indirect calorimetry in critically ill patients.

Objective: To compare the oxygen consumption index measured by using indirect calorimetry (VO2I Delta) with a portable metabolic cart and calculated according to Fick's principle (VO2 I Fick) in critically ill patients.

Methods: Fourteen patients (10 men and 4 women, mean age 39.4 +/- 5.
