Intravenous (IV) sedatives are a crucial component of modern medical practice, offering rapid onset and precise control of sedation levels. These medications are administered directly into the bloodstream, allowing for quick action and easy dose adjustments. Here's a comprehensive overview of IV sedatives:

a) Propofol:

Fast-acting, short duration

Used for induction and maintenance of anesthesia

Popular in ICU for continuous sedation

b) Midazolam:
