Influence of preoperative pulmonary function on postoperative results in cardiac surgery patients - Postoperative effects of preoperative pulmonary function

The mechanical ventilation and postoperative hospital stay in the combined group was significantly longer than that in others. Patients in the restrictive group had a significantly longer postoperative ventilation or hospitalization than those in the normal group. However, there were no significant differences in the 30-day mortality rates between the groups. There also was a significant negative correlation between the percent predicted FEV1.0 and mechanical ventilation and postoperative hospitalization.
