Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expect to see that maintaining a positive pressure during CPB and recruitment maneuver after CPB improves blood oxygenation levels compared to the control group in the immediate postoperative cardiac surgery. The variables that analyze gas exchange will be obtained by arterial blood gas sample in 5 stages: pre extra corporeal circulation (before the patient enters into CPB), after extra corporeal circulation (after sternum closure), admission to the unit intensive, 1st postoperative (24 hours after surgery) and 2nd postoperative (48 hours after surgery).;Expect with the recruitment maneuver decrease the duration of mechanical ventilation in the immediate postoperative period, decreasing pulmonary complications and shorter ICU stay, compared to control patients who underwent no intervention ventilation. For analysis of these outcomes, we use an evaluation form that will be annotated data restistência compliance and lung, as well as the time of ICU admission, time of extubation and mechanical ventilation. | — |
Secondary
| Measure | Time frame |
|---|---|
| Expect with recruitment maneuvers decrease the incidence of systemic inflammatory response in the immediate postoperative cardiac surgery and thus reduce pulmonary complications,compared to control patients who underwent no intervention ventilation. These variables will be assessed by inflammatory cytokine interleukin-1 among them, Interleukin-6, Interleukin-10 and Interferon-Gamma | — |
