Background
Post-operative cognitive dysfunction (POCD) is an important issue that is associated with substantial morbidity and increased mortality, especially in elderly patients who have undergone major surgical procedures under general anesthesia. The symptoms of POCD may last for several months after surgery, leading to extended hospital stays, a decline in life quality, an increased need for social assistance, and significant financial strain on the patients.
Settings and Design
It was a Prospective Randomized interventional study.
Methods
A total of 120 patients (≥65 years) were divided into two groups of 60 each for this study at Alexandria Main University Hospital and planned for elective lumbar disc surgery under general anesthesia. Either propofol or sevoflurane was used to maintain anesthesia after it was induced. MMSE score, S100β levels and hemodynamic measures were all evaluated.
Results
Incidence of POCD was not statistically significant different between the two studied groups. There was a statistical significant negative correlation between S100β level and MMSE score in early post-operative period.
Conclusion
In terms of POCD, both propofol-based and sevoflurane-based anesthesia have the same effects on cognitive functions in early post-operative period.
