The impact of regional versus general anesthesia on postoperative neurocognitive outcomes in elderly patients undergoing hip fracture surgery: A systematic review and meta-analysis

No significant difference was found in the incidence of cognitive dysfunction after either general or regional anesthesia in elderly patients. Our finding of similar outcomes at 24 h, 3 days and 7 days postoperatively with either technique suggests that anesthesia choices for hip-fracture surgery may be based on the individual characteristics of each patient rather than on anticipated differences in clinical outcomes.
