  1. Patients from the PCC(+) group were observed to have experienced significantly longer durations of intubation times, ICU stays, and postoperative hospital stays, and they also had dramatically higher rates of pulmonary infection, MODS and tracheotomy after surgery. The postoperative mortalities of the PCC(+) group had a trend of increasing, but there were no significant differences between the patients in these two groups. Patients from the PCC(+) group spent more money compared with the patients in the PCC(−) group
  2. PCC Postoperative cerebral complications, POD Postoperative delirium, POCD Postoperative cognitive dysfunction, DEA Delayed emergence from anesthesia, ARDS Acute respiratory distress syndrome, MODS Multiple organ dysfunction syndrome, ECMO Extracorporeal membrane oxygenation
  3. atwo patients with postoperative comas were not enrolled in the analysis of recovery times; b severe heart failure reached NYHA grades III-IV; c required renal replacement therapy; d included meteorism, nausea, vomiting, abdominal pain, diarrhea, constipation, and gastrointestinal hemorrhage; e within 48 h after surgery; f up to the end of the follow-up period
