Aim:Postoperative cognitive dysfunction (POCD) describes a decline in cognitive ability from a patient's baseline that starts in the days after surgery and is prevalent in 1% of elderly patients after 1 yr.Hence; the study was conducted for evaluating the impact of maintaining an individualized intraoperative blood pressure targeton the incidence of Postoperative Cognitive Dysfunction (POCD)and postoperative delirium in elderly patients under general anesthesia.Materials and Methods:A total of 50 patients of more than 70 years of age were enrolled. Complete demographic and clinical details of all the patients was recorded. Only those patients were enrolled which were scheduled under general anesthesia. Patients were randomized into two study groups: Group A: Patients with mean arterial pressure (MAP) ≥ 90% of preoperative values, and Group B: Patients to a more liberal intraoperative blood pressure management.Neuropsychological assessment of all the patients was carried out preoperatively and postoperatively after three months. Incidence of POCD at three months and postoperative delirium were assessed.Results:POCD was seen in 20 percent of the patients of group A and in 12 percent of the patients of group B.Delirium was seen in 32 percent of the patients of group A and in 36 percent of the patients of group B. non-significant results were obtained while comparing the incidence of POCD and delirium among the patients of the two study groups. Conclusion: No Correlation Found Between Intraoperative Hypotension and Postoperative Cognitive Dysfunction or Delirium in Elderly Patients Undergoing General Anesthesia.
