Conclusions
We revealed POCD patients had a significantly longer preoperative hospitalization period when compared to non-POCD patient group. In addition, POCD development was associated with advanced age, presence of comorbidity, high ASA scores, prolonged surgery duration, increased intraoperative blood loss amount and low postoperative hematocrit levels. We consider prolonged preoperative hospitalization periods were related with early POCD development and patients had risk factors should be closely monitorised post operatively in terms of cognitive functions.
