A CRNA, or Certified Registered Nurse Anesthetist, is an advanced practice nurse who administers anesthesia to patients before, during, and after surgery. CRNAs are among the highest-paid nursing professionals in the United States, earning a median salary of $223,210 per year as of 2024. They work alongside surgeons, anesthesiologists, and other physicians to keep patients pain-free and safe throughout medical procedures.
What a CRNA Actually Does
A CRNA’s core responsibility is managing every phase of anesthesia care. Before surgery, they assess the patient’s health, review medical history, and explain what to expect. During the procedure, they administer the anesthesia medications, then continuously monitor the patient’s heart rate, blood pressure, oxygen levels, breathing, and body temperature. After surgery, they manage the patient’s recovery from anesthesia, watching for complications and controlling pain.
CRNAs provide anesthesia for patients of all ages, from infants to the elderly, and across a wide range of procedures. Their work isn’t limited to operating rooms in large hospitals. They practice in outpatient surgery centers, pain management clinics, dental offices, plastic surgery practices, GI labs, and ophthalmology centers. In large teaching hospitals, a CRNA might handle anesthesia for trauma cases, heart surgeries, organ transplants, and neurosurgeries. At a smaller community hospital, the caseload leans more toward orthopedic, urological, and general surgeries.
How to Become a CRNA
The path to becoming a CRNA is long and selective. It starts with earning a bachelor’s degree in nursing and becoming a registered nurse. From there, you need at least one year of full-time experience working in an intensive care unit or critical care setting, though most programs prefer two years. ICU experience is non-negotiable because it builds the kind of rapid clinical decision-making that anesthesia demands.
As of 2025, all aspiring CRNAs must earn a Doctor of Nursing Practice (DNP) in nurse anesthesiology from an accredited program. These doctoral programs typically run about 36 months and include roughly 2,500 hours of hands-on clinical anesthesia training. After completing the program, graduates must pass the National Certification Examination to earn the CRNA credential.
Certification isn’t a one-time event. CRNAs maintain their credentials through an eight-year continuing education cycle that includes coursework in airway management, anesthesia equipment and safety, pharmacology, and human physiology. Midway through, they complete check-ins with the credentialing board, and in the second half of the cycle, they take a 150-question assessment to demonstrate ongoing competency.
CRNAs vs. Anesthesiologists
This is one of the most common questions people have. Both CRNAs and anesthesiologists provide anesthesia, but their training paths differ significantly. An anesthesiologist is a physician who completes four years of medical school, four years of residency, and often one to two additional years of fellowship training, totaling eight to ten years of post-graduate education and 12,000 to 16,000 hours of patient care. A CRNA completes a three-year doctoral nursing program with about 2,500 clinical hours, building on top of their prior nursing degree and ICU experience.
In practice, both professionals administer the same types of anesthesia and monitor patients through surgery. The working relationship varies by state and by facility. In some states, CRNAs work under the supervision of a physician or anesthesiologist. In others, they practice independently. As of 2017, seventeen states had opted out of the federal requirement for physician supervision of CRNAs, and that number has continued to grow. In these states, CRNAs can evaluate patients, choose an anesthetic plan, administer it, and manage recovery without a physician co-signing their decisions.
Why CRNAs Matter in Rural Areas
CRNAs play a particularly critical role in parts of the country where physician anesthesiologists are scarce. In rural counties across the U.S., over 81% have no anesthesiologist at all. Without CRNAs, many of these communities would have no access to surgical care. Research on rural hospitals has found that anesthesia services were generally not reported as a limitation in communities with CRNAs, because these providers had strong, diverse skill sets and were often given high levels of clinical autonomy.
This rural impact is a major reason the profession continues to grow. The Bureau of Labor Statistics projects 9% employment growth for nurse anesthetists between 2024 and 2034, which is faster than average for all occupations.
Salary and Career Outlook
CRNAs are consistently among the highest-earning nurses in the country. The median annual salary was $223,210 in May 2024, according to the Bureau of Labor Statistics. Actual earnings vary based on geographic location, practice setting, and whether the CRNA works independently or within a physician-led team. CRNAs in states that allow independent practice, or those willing to work in rural or underserved areas, often command higher compensation.
The combination of strong demand, high autonomy in many states, and flexible practice settings makes the CRNA career path one of the most competitive in advanced nursing. Getting there requires years of critical care experience and a doctoral degree, but for nurses drawn to high-acuity clinical work, it represents one of the clearest routes to both professional independence and financial reward.
