Design outcomes

Primary

MeasureTime frame
To calculate the incidence and prevalence of pre and postoperative delirium in elderly patients undergoing noncardiac surgery under regional anaesthesia.Timepoint: a total of 100 elderly patients (age group 60 years undergoing noncardiac surgeries under regional anaesthesia will be assessed with MMSE and DOS scale for delirium preoperatively at the time of pre-anaesthesia checkup one day prior to surgery and then postoperatively after shifting the patient to the recovery room, 24 and 48 hours after surgery. The scores of the MMSE and DOS scale at the respective time intervals will be measured and recorded—

Secondary

MeasureTime frame
To compare the efficacy of MMSE scale and DOS scale as a predictive tool for the detection of postoperative delirium in elderly. To compare the change in the severity levels of delirium postoperatively from preoperative levels in patients with preoperative delirium. Timepoint: a total of 100 elderly patients (age group 60 years undergoing noncardiac surgeries under regional anaesthesia will be assessed with MMSE and DOS scale for delirium preoperatively at the time of pre-anaesthesia checkup one day prior to surgery and then postoperatively after shifting the patient to the recovery room, 24 and 48 hours after surgery. The scores of the MMSE and DOS scale at the respective time intervals will be measured and recorded—
