Anaesthesia
Anaesthesia chart were recorded standardly based on the guidelines of
Chinese Society of Cardiothoracic and Vascular Anesthesiology and
combined intravenous and inhalation anesthesia were used in all
patients.
There were no differences with respect to the ASA PS III(American
Society of Anesthesiologists Physical Status)(P=0.102) while
significantly more ASA PS II patients in Delirium group, no significant
difference was observed in duration of the surgery and duration of
anesthesia, and preoperative anxiety. There were no significant
differences as to dexmedetomidine and propofol use (P=0.256, P=0.278).
In Delirium group, patients had significantly more EBL and
intraoperative blood transfusion (P<0.001, P=0.003), and furthermore
significantly lower LMAP (P<0.001) was recorded in Delirium group while
no difference was detected as to LHR between two groups (P=0.102).
