Could staying active before surgery help prevent postoperative delirium?
Staying active before surgery may do more than strengthen the body for recovery—it may protect the brain. Regular physical activity at least seven times a week before cancer surgery was linked to a lower risk of developing postoperative delirium, according to research presented at the ANESTHESIOLOGY 2026 annual meeting.
A new study presented at the ANESTHESIOLOGY 2026 annual meeting suggests that staying active before cancer surgery may help prevent postoperative delirium. The research, conducted by Melody Haratian and Jeffrey Huang, found that patients who engaged in regular physical activity, including walking and moderate to vigorous exercise, at least seven times a week were 50% less likely to develop postoperative delirium compared to those who were less active.
Postoperative delirium, a state of confusion affecting about 20% of surgical patients, particularly older adults, can lead to longer hospital stays, delayed recovery, and increased risk of death. The study emphasizes the importance of preparing for surgery through prehabilitation, which includes exercise and nutrition strategies, to improve recovery and outcomes.
Patients are advised to discuss safe ways to stay active with their healthcare team and consider participating in a prehabilitation program before undergoing major surgery.
