It is common to be afraid of the unfamiliar path. Once you begin your educational career as an anesthesiologist, you will do clinical rounds in different hospital units and gain a wealth of experience. This experience will give you confidence. This confidence will help dissolve your fears. If your path leads you into anesthesiology, you will be equipped with all the mental and physical tools you need to be a successful anesthesiologist. I shadowed the lead anesthesiologist for a local hospital and I never saw fear from him. What I did see, was caring concern for his patients as he made his rounds to see his patients. I saw a great mentor and teacher who checked in on his staff to make sure they had everything they needed.
After the COVID-10 pandemic subsides, I highly recommend reaching out to a hospital in your community and requesting to shadow for a few hours or a few days. Whatever they are willing to allow you to do, will give you tremendous insight on the day to day of that career.
