Abstract

BACKGROUND: Cardiac patients undergoing open heart surgery usually require ventilatory support that involves ICU admission in the postoperative period. We tried to find out determinants of postoperative ventilatory support time.
METHODS
We reviewed the medical records of 56 open heart surgery patients retrospectively in terms of their disease, preoperative physical status, age, post-bypass arterial oxygen tension/inspired oxygen fraction (PaO2/FIO2) ratio, number of inotropics used and searched the relationship between each factor and postoperative intubation time.
RESULTS
None of the factors except the number of inotropics used had an significant influence on the postoperative intubation time.
CONCLUSION
In open heart surgical patients their disease, preoperative physical status, age, postbypass PaO2/FIO2 ratio do not affect postoperative intubation time rather than number of inotropics used does.
