If you're exploring a career path in anesthesia, you may be considering two important roles: certified anesthesiologist assistant (C-AA) and certified registered nurse anesthetist (CRNA).

While both careers play a critical role to patient care during medical procedures, their education pathways, clinical training and scope of practice differ. Kansas City University (KCU) is committed to preparing future health leaders who embrace patient-centered care and thrive in collaborative environments. KCU offers its Master of Health Science in Anesthesiologist Assistant program on the Joplin campus, providing students with rigorous training and hands-on clinical experience 

Understanding the difference between a C-AA and a CRNA can help you determine which anesthesia career best aligns with your background, interests and long-term career goals. 

What is a certified anesthesia assistant? 

A certified anesthesia assistant is a health care professional who works under the supervision of a board-certified anesthesiologist. C-AAs play a crucial role in delivering anesthesia safely, from pre-procedure preparations to post-operative care. They assistphysician anesthesiologists by monitoring patient vitals, adjusting anesthesia levels and ensuring patients remain comfortable throughout their procedures. 

C-AAs earn a Master of Health Science in Anesthesiologist Assistant and complete intensive clinical training. Coursework focuses on anatomy, pharmacology and advanced patient care techniques, preparing graduates to thrive as essential members of health care teams. C-AAs practice within a physician anesthesiologist-led model to maintain the highest standards of safety and collaboration.  

What is a CRNA? 

Certified Registered Nurse Anesthetists (CRNAs) are advanced practice nurses trained to administer anesthesia. CRNAs practice in a variety of settings including surgical centers, hospitals, obstetric and rural health care environments. Depending on state regulations,  CRNAs may work independently or as part of an anesthesia care team. 

The path to becoming a CRNA begins with a bachelor’s degree in nursing (BSN) and at least one year of critical care nursing experience. CRNAs must then complete a doctoral-level nurse anesthesia program (DNP or DNAP). Their advanced clinical education prepares them to deliver comprehensive anesthesia care, and in many settings, practice with a high degree of autonomy.  

How are C-AAs and CRNAs similar? 

Both certified anesthesia assistants and CRNAs:  

  • Administer anesthesia and monitor patients during procedures. 
  • Complete advanced degrees and extensive clinical training. 
  • Collaborate with interdisciplinary health care teams to ensure safe, effective patient care.
