Scared of waking up during Breast Lift surgery. Please help :( - how to rationalize?

Must patients who have some awareness during surgery had sedation, not full general anesthesia. With general anesthesia your risk of waking up are remote.

It’s completely understandable to feel nervous about anesthesia and waking up during surgery, but the risk is extremely low, especially for breast lift surgery.
For most cosmetic surgeries, including breast lifts, general anesthesia is used, which makes it very unlikely that you'll "wake up" during the procedure. For a breast lift, there is typically no need for paralyzing drugs that completely immobilize you. The anesthesia team monitors you throughout the procedure and adjusts the level of anesthesia if needed. If there is any sign that you might be feeling discomfort, they will administer more anesthesia to ensure you're unconscious and comfortable. Anesthesiologists use advanced monitoring equipment to ensure you remain safely under anesthesia throughout the surgery. Be sure to discuss any concerns with your anesthesiologist before surgery so that you feel comfortable!
Remember, the vast majority of people who undergo breast lift surgery do so without any issues with anesthesia. The surgical environment, particularly in accredited surgical centers with experienced anesthesiologists and surgeons, is designed for safety.

You should not require paralyzing anesthesia for a breast lift, but even if you did modern methods of monitoring make it virtually impossible that you could be awake but paralyzed. Feel free to ask your anesthesia provider about it before surgery.
