National CRNA Week is January 22-28, 2017. The Department of ACCM celebrates our Certified Registered Nurse Anesthetists (CRNAs) and Student Registered Nurse Anesthetists (SRNAs) who provide world class care to our patients. Nurse anesthetists have been providing anesthesia care to patients in the United States for more than 150 years. The Certified Registered Nurse Anesthetist (CRNA) credential came into existence in 1956. Our department thanks them for the service excellence they provide every day.
