[Assessment of a risk scale in patients submitted to coronary artery bypass surgery: analysis of 400 cases].
The objective of this paper was to assess a risk scale based on a protocol developed at The Cleveland Clinic Foundation for the coronary artery bypass surgery using preoperative and perioperative parameters and the patient's physiological profile at the admission in the intensive care unit (ICU). ⋯ It was possible to conclude that the parameters recorded at the preoperative and at the ICU admission were correlated with the probability of death and complications and the ICU admission parameter, associated with the preoperative parameters and intraoperative factors bring more information for the prognostic of death and complications. The adjusted models adequately express the death and complications probabilities estimate, due to the preoperative, intraoperative and ICU admission parameters.

[The use of the cuff leak test as a factor to predict laryngospasm].
Weaning patients from mechanical ventilation is a challenge in the intensive care unit (ICU) practice and is related to some complications. One of these is the pos-extubation laryngospasm, an event that can be anticipated for the cuff leak test (CLT). The objective was demonstrate that the CLT is a simple, reliable and low costs method to available the presence of obstruction in high airway in patients under weaning ventilator. ⋯ The CLT can be considerate a good index to predict laryngospasm pos-extubation, when considerate the studied population characteristics.

Mechanical ventilation is considered a basic element of life support in the intensive care unit and is essential for patients with acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). Experimental studies have demonstrated that mechanical ventilation with high volumes and/or high pressures can exacerbate (VALI) or induce lung injury (VILI) with histological aspect similar to ALI/ARDS. ⋯ It is fundamental to understand the mechanisms related to volutrauma, atelectrauma, and biotrauma to avoid ventilator-associated lung injury.

[A comparative study between early and late tracheostomy in patients ongoing mechanical ventilation].
To assess the incidence of tracheostomy in patients submitted to mechanic ventilation (MV); to compare the length of stay (LOS), duration of MV, APACHE II and mortality among patients submitted to tracheostomy, according to the moment of its application (early or late). ⋯ The incidence of tracheostomy was high, being associated to a smaller ICU mortality but with a longer LOS and more complications. There was no significant difference regarding the destination of the patients when submitted to early or late tracheostomy.
