NCT ID NCT07536568

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study is testing whether giving a caffeine tablet under the tongue at the end of surgery can help elderly patients (65 and older) wake up faster and feel less agitated after general anesthesia. Half of the 50 participants will get caffeine, the other half a placebo. The goal is to see if this simple approach can speed recovery and improve comfort after eye surgery.
