Nurse anesthetists, also known as certified registered nurse anesthetists (CRNAs), are one of four classifications of advanced practice nurses (APNs). They are registered nurses (RNs) with advanced training in anesthesiology. They are responsible for administering, supervising, and monitoring anesthesia-related care for patients undergoing surgical procedures. General anesthesia is not necessary for all surgical procedures; therefore, nurse anesthetists also work on cases in which they provide various types of local anesthesia—topical, infiltration, nerve-block, spinal, and epidural or caudal. There are more than 42,000 nurse anesthetists working in the United States.
