a) Logistic regression analysis with enter method was used.

SAPS, Simplified Acute Physiology Score; APACHE II, Acute Physiology and Chronic Health Evaluation; RCRI, Revised Cardiac Risk Index; OR; Odds Ratio; CI, Confidence Interval.

*Adjusted for age, length of PACU stay, erythrocytes, RCRI and SAPS II. All variables were forced into the model in logistic regression analysis.
