Can a new sedative make bronchoscopy safer and smoother?

This trial tests whether ciprofol, a newer sedative, provides better and safer sedation than the standard drug propofol for people undergoing bronchoscopy, a procedure to examine the airways. Both are given with a low dose of sufentanil for pain relief. The study involves 100 adults aged 35 to 65 with mild or no systemic disease, randomly assigned to receive one of the two sedatives. Researchers will measure the total sedative dose needed, side effects like breathing or blood pressure changes, and how quickly patients wake up and recover.
