Abstract
Background
We aimed to investigate the factors affecting the length of intensive care unit (ICU) stay in patients undergoing isolated on-pump coronary artery bypass (CABG). We also aimed to evaluate effective factors on morbidity, mortality, and survival among patients with prolonged ICU stay.
Methods
Between January 2002 and December 2009, a total of 1,657 patients underwent isolated on-pump CABG in our clinic. Prolonged ICU stay (>2 days) was present in 532 patient (32.1 %).
Results
Diabetes (OR 1.49, P = 0.006), hypertension (OR 1.37, P = 0.029), chronic obstructive pulmonary disease (OR 9.06, P < 0.0001), preoperative ejection fraction (EF) (OR 3.35, P < 0.0001), CPB time (OR 0.049, P < 0.0001), cross-clamp time (OR 2.20, P = 0.023), prolonged inotropic support (OR 40.40, P < 0.0001), prolonged ventilatory support (OR 0.26, P = 0.022), postoperative renal insufficiency (OR 4.50, P = 0.004), postoperative atrial fibrillation (OR 8.00, P < 0.0001), and postoperative blood transfusion (>3 units) (OR 3.23, P = 0.007) were the independent predictive factors of prolonged ICU stay (>2 days). Postoperative mortality rate was 7 % (n = 37) and 2.3 % (n = 26) in patients with length of ICU stay >2 days and length of ICU stay ≤2 days (P < 0.0001). Mean follow-up was 51.00 ± 0.79 and 44.76 ± 1.07 months among patients with length of ICU stay ≤2 days and length of ICU stay >2 days (P < 0.0001).
Conclusions
Postoperative mortality was higher in patients with prolonged ICU stay. Mean follow-up was shorter in patients with prolonged ICU stay.
