NCT ID NCT04965324
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows over 6,600 elderly patients (aged 60+) who had major surgery to see if lighter anesthesia helps them live longer. The original trial found no difference in survival at one year, but this follow-up checks for effects beyond that, including on cancer recurrence and memory problems. Researchers aim to learn whether adjusting anesthesia depth can improve long-term outcomes.
