Does the time of day affect sleep and recovery after general anesthesia?
This study looks at how the time of day your surgery happens affects how well the anesthesia drug ciprofol works and how smoothly you wake up. It compares morning and afternoon surgeries to see if your body's internal clock changes the drug's effects.

This study tests whether ciprofol, a newer sedative, can help prevent low blood pressure during surgery in older patients who are already taking medications for high blood pressure or heart failure (called RAS inhibitors). It may be a good option if you're 65 or older, on these medications for more than 3 months, and having abdominal surgery lasting over 2 hours.
This study compares two types of anesthesia to see which one better preserves brain function and recovery after laparoscopic gallbladder removal. It aims to help patients wake up more clearly and maintain cognitive function after surgery.
This study looks at how the sedative drug ciprofol works differently in people with insomnia compared to those who sleep well. It aims to help doctors give the right dose for your type of surgery.
This study looks at how sleep problems before surgery affect the amount of anesthesia needed and how well you recover after non-cardiac surgery. The goal is to help doctors personalize care for better recovery.
This study compares two medicines used to put patients to sleep before major abdominal surgery. It aims to find which one is safer and works better for frail older adults.
This trial compares two sedative medicines, ciprofol and propofol, to see which works better for older patients having surgery without a breathing tube. It aims to find the safer option for your heart and lungs.
