1 February 2022
Randomized clinical trials General
Li T, Li J, Yuan L, Wu J, Jiang C, Daniels J et al, for the RAGA Study Investigators.
JAMA 2022; 327: 50-58.

Some 950 patients over 65 years old were included. Postoperative delirium within seven days was recorded in 5.1 per cent in those who had a GA, compared to 6.2 per cent who had spinal or epidural, P=0.48.

Comment: surprisingly low rate; reproducible in other specialties?
