|At UW Health, certified registered nurse anesthetists work on teams with anesthesiologists, surgeons, physicians and other professionals to deliver anesthesia care for medical and surgical procedures in clinics and the hospital. A certified registered nurse anesthetist cares for a patient before, during and after a medical procedure or surgery by performing a patient assessment, preparing the patient for anesthesia, administering and maintaining the anesthesia to ensure proper sedation and pain management, overseeing patient recovery from anesthesia and caring for the patient's immediate post-operative needs. A certified registered nurse anesthetist is a registered nurse with a master's or doctorate degree. They have advanced education, training and certification in anesthesia care of patients. Certified registered nurse anesthetists are also referred to as advanced practice registered nurses (APRNs) and advanced practice providers (APPs).
