Anesthetics are special medications used to prevent pain during medical procedures. They work by blocking the sensation of pain in specific areas of the body or by putting a person into a deep sleep, so they don’t feel anything at all. There are different types of anesthetics, including local anesthetics, which numb a small area, and general anesthetics, which affect the entire body. Doctors carefully choose the right anesthetic based on the procedure and the patient's health. Anesthetics are commonly used in surgeries, dental work, and other medical treatments to ensure that patients remain comfortable and pain-free throughout the process.
