Nurse anesthetists provide anesthesia and related care before and after surgical, therapeutic, diagnostic and obstetrical procedures. They also provide pain management and emergency services, such as airway management. The practice of anesthesia is a recognized specialty within the profession of nursing, and nurse anesthetists are essential to the health care workforce. The Certified Registered Nurse Anesthetist (CRNA) administers anesthesia for all types of surgical cases, from the simplest to the most complex.
In the majority of cases, anesthesia is administered by a CRNA. CRNAs work with your surgeon, dentist or podiatrist, and may work with an anesthesiologist (physician anesthetist). CRNAs are advanced practice registered nurses with specialized graduate-level education in anesthesiology. For more than 150 years, nurse anesthetists have been administering anesthesia in all types of surgical cases, using all anesthetic techniques and practicing in every setting in which anesthesia is administered.
