Design outcomes

Primary

Measure	Time frame
The primary endpoint of the study is a descriptive comparison between the two groups: prolonged mechanical ventilation and non-prolonged mechanical ventilation. Another main objective of the retrospective analysis is to identify risk factors for prolonged mechanical ventilation after cardiac bypass surgery. Patients will be divided into two groups (Group I = ventilation < 24 hours, Group II = ventilation = 24 hours). Logistic regression will be used to identify risk factors for Group II.	—

Secondary

Measure	Time frame
Furthermore, it will be investigated whether prolonged ventilation (=24h) is also associated with prolonged length of intensive care stay, length of hospital stay or ultimately with increased hospital mortality.	—
