About this trial
The goal of this clinical trial is to learn if an extended emergence from anesthesia can improve recovery room (Post-Anesthesia Care Unit or PACU) outcomes in lower-leg or foot surgery with nerve blocks. The primary questions it aims to answer are:
* Does a longer wake-up help participants think more clearly soon after surgery compared with usual approaches? * Does it lower pain scores, lower the amount of pain medications used, and shorten the time it takes to go home from recovery room?
Researchers will compare 2 groups of adults who are having similar lower-extremity orthopaedic surgeries with regional and propofol anesthesia.
