Perioperative Complications
There was no significant difference in 30-day in-hospital mortality (P=0.072) between two groups, and there was also no significant difference in major bleeding (P=0.065), arrythmia (P=0.089), low cardiac output (P=0.165), as well as the median ICU (intensive care unit, ICU) stay (P=0.319) and hospital stay (P=0.821) between two groups. Postoperative reoperation rate were marginally more common (P=0.041) in Delirium group, and postoperative pulmonary and gastrointestinal complications (P=0.098, P=0.061) were not statistically different between the two groups. MoCA score which is a convenient tool for estimating patients’ global cognitive functioning was significantly lower in Delirium group (P=0.001). (Table 4)
