Background: Cerebral aneurysm rupture is a distinct entity among various causes of cerebrovascular accident. Despite the current concept of early surgical clipping to prevent consequences of ruptured aneurysm in good grade subarachnoid hemorrhage patients, 40–50% have postoperative cognitive dysfunction (POCD) on a long- term basis. Here, we compared the effect of two commonly used anesthetic agents on cognitive function following cerebral aneurysmal surgery, i.e., propofol and desflurane. Methods: We conducted a prospective double-blind clinical study in 70 patients who were randomized to receive maintenance anesthetic agents either propofol or desflurane. The cognitive functions of patients were studied at the time of the discharge from a hospital or at 2 weeks following surgery whichever was early using the Hindi version of the Montreal Cognitive Assessment scale. The hemodynamic parameters, brain relaxation score at the different time intervals, were also studied. Results: There was no difference between the two anesthetic agents in terms of incidence of POCD (65.4% vs. 82.6%, P > 0.05) at the time of discharge or at 2 weeks following surgery. The mean POCD score in propofol and desflurane group was 22.81 ± 4.45 and 19.09 ± 5.66 which was statistically significant (P-value-0.01). The scores for domains of executive function, attention, and orientation were better with propofol group than desflurane group. Intraoperative hemodynamics and brain relaxation scores were similar in both groups. Conclusion: A significant number of patients undergoing aneurysmal neck surgery experienced POCD although incidence remained similar in both groups. However, it appears that mean cognitive score and certain domains of cognitive functions especially the executive function, attention, and orientation were better preserved with the use of propofol when compared to desflurane at the time of discharge or on 2 weeks following surgery whichever was early.

The article is devoted to the study of postoperative cognitive dysfunction — a syndrome that is often found in the postoperative period and does not depend on the volume of surgeon. Based on the analysis of the results of modern studies, the authors cite the most likely etiological causes of the syndrome, grouped according to different categories of risk factors. The pathogenetic algorithm for cognitive dysfunction includes the appearance of systemic inflammation, improving blood-brain barrier permeability with the endothelial dysfunction, the migration of inflammatory agents into the central nervous system, and the formation of oxidative stress. The clinical manifestations of cognitive deficit in the outcome of surgeon performed under general anesthesia, the authors illustrate with their own observations of patients with a neurosurgical profile with spinal pathology operated on with the use of propofol anesthesia, comparing the results of neuropsychological testing with an assessment of the level of anxiety. In conclusion, the authors outline a strategy for the prevention of postoperative cognitive dysfunction and recommend conducting neuropsychological rehabilitation as an important component of postoperative recovery for all patients with a diagnosed cognitive deficit that occurred after surgery.
