Here are a few of the medical personnel or specialists you might encounter:
Anesthesiologist: An anesthesiologist or certified registered nurse anesthetist (CRNA) administers medicine just before surgery to keep you asleep during the procedure. The anesthesiologist is present during the operation to watch over you and make sure you have no pain.
Surgeon: A surgeon is the person who operates on you if you are having surgery.
Specialists: Some doctors are experts in different fields, like cardiology (the heart and circulatory system), pulmonology (the lungs), or oncology (cancer care).
Child life specialist: A child life specialist is trained to talk to kids and teens about medical procedures and other parts of the hospital stay. They comfort patients if they are upset about something or need some extra support, and organize "play time" for hospitalized kids and teens to get together and hang out.
Intern or resident: Interns and residents are doctors who are training in a specialty such as pediatrics or surgery.
IV team and phlebotomists: Many hospitals have an IV team that does IV placement (an IV is a small straw-like tube that is placed into a vein under the skin to directly give someone fluids or medicines) or phlebotomists who draw any blood that is needed for tests.
