Certified Registered Nurse Anesthetists (CRNAs)

A Certified Registered Nurse Anesthetist (CRNA) is an advanced practice nurse who has completed a graduate level education and a board certification in anesthesia. A nurse anesthetist specializes in every aspect of the pre-operative, intra-operative and post-operative care of a patient in every type of surgical procedure. Today, nurse anesthetists practice in all 50 United States and administer approximately 34 million anesthetics each year. Approximately 65% of CRNAs in the US practice in collaboration with anesthesiologists as members of the Anesthesia Care Team.

At both NYP/Weill Cornell Medical Center and NYP/Lower Manhattan Hospital, our Department of Anesthesiology has a large practice with over 60 CRNAs who are an integral part of our teams. In addition to providing excellent care, the CRNAs are all clinical instructors for Columbia University's Nurse Anesthesia Program providing students with one-on-one instruction everywhere anesthesia is provided.
