Between february 1999 and september 2000 625 consecutive patients undergoing open heart surgery were entered into the study. Logistic regression analysis showed that postoperative pulmonary complications (p=0.03), blood usage (p=0.05) and the use of intra aortic balloon pump (p=0.02) increase ICU stay.
We speculate that pulmonary complications, particularly the nosocomial infections, will decrease by early extubation. Precise surgery and effective cardiopulmonary bypass management strategies will decrease the blood and intra aortic balloon pump usage, thus leading to the shortening of ICU stay.
