Working in the medical field as an anesthesiologist or an assistant requires a good bit of skill. After working for a few years in the job, you might find that you will need an anesthesia recertification in order to maintain the license that you have. This is often easy to do and only requires a few classes and a test or two. Once you have received the recertification, you could make more money on your job or have other job opportunities open up to you.
In order to take the courses that you need, you might have to brush up on some of the skills that you use in the job. Biology and chemistry are two of the courses that you should refresh yourself in as you are working with patients through the day. You might need to demonstrate that you know how to use the equipment involved in the job or that you know how to administer the proper amounts of anesthesia. Another issue that you might need to demonstrate is what to do in an emergency if someone is affected by the anesthesia that is used. You will need to know of the safety guidelines that are used on the job as well as how to handle the medications that are used.
