Intravenous anesthetics are medications administered directly into the bloodstream to induce anesthesia, a state of controlled unconsciousness. They are commonly used for surgeries and other medical procedures, allowing patients to remain pain-free and unaware during treatment. These drugs work quickly, providing rapid onset of sedation. Common examples of intravenous anesthetics include propofol, etomidate, and thiopental. Each of these agents has unique properties, such as duration of action and side effects, making them suitable for different clinical situations. Anesthesiologists carefully select the appropriate drug based on the patient's needs and the type of procedure being performed.
