An anesthesiologist is someone who anesthetizes patients. They can help sedate patients and put them under for surgeries or other medical procedures. They help prepare their patients for procedures and make sure they are not experiencing any pain or fear associated with the treatment or procedure they are undergoing. They work closely with other doctors, surgeons, and specialists to ensure that patients are being treated properly.

Emergency medicine is a subspecialty that focuses on patients who need immediate and often intensive care. These physicians must be able to handle medical problems quickly to avoid potential complications with their patients. With their knowledge of emergency medicine comes knowledge about many other types of medicine, as they must be able to respond to patients who present a variety of symptoms and problems. They will also have a thorough understanding of emergency medical devices.
