Cerebral oximetry and cognitive dysfunction in elderly patients undergoing surgery for hip fractures: a prospective observational study.

Aim: This study was conducted to examine perioperative cerebral oximetry changes in elderly patients undergoing hip fracture repair and evaluate the correlation between regional oxygen saturation (rSO(2)) values, postoperative cognitive dysfunction (POCD) and hospital stay.

Materials And Methods: This prospective observational study included 69 patients. Data recorded included demographic information, rSO(2) values from baseline until the second postoperative hour and Mini Mental State Examination (MMSE) scores preoperatively and on postoperative day 7.
