What is an Anesthesiologist Assistant?

An anesthesiologist assistant (AA) is a highly trained healthcare professional who focuses solely on anesthesia delivery and monitoring under the supervision of a licensed anesthesiologist. Originating in the late 1960s, this role was designed to meet the need for specialized, non-physician anesthesia support. 

Today, AAs typically work as part of an anesthesia care team, helping ensure patient safety and comfort before, during, and after surgical procedures. State laws vary, so individuals considering this career should verify local licensing requirements.

Responsibilities in a Hospital or Surgical Center

Within a hospital or surgical center, anesthesiologist assistants, under the direct supervision of an anesthesiologist, are generally responsible for:

• Reviewing a patient’s pre-anesthesia medical history and assessing readiness for anesthesia
• Assisting in administering anesthesia during surgical procedures
• Continuously monitoring patient vital signs and anesthesia depth throughout the operation
• Contributing to post-operative evaluations to assess patient recovery

Required Skills and Qualifications

To become an anesthesiologist assistant, most candidates must complete a Master of Science in Anesthesia from an accredited program. Beyond formal education, successful AAs typically possess:

• Strong critical thinking and rapid decision-making abilities
• Exceptional attention to detail to minimize risk of errors
• Effective teamwork skills for working closely with anesthesiologists and other healthcare staff
• In-depth knowledge of human physiology, pharmacology, and medical systems
• Excellent communication skills for coordinating care and addressing patient concerns
• The resilience and focus required to thrive under high-pressure, high-stakes conditions

State-Specific Practice Regulations

Because regulations vary, the ability to practice as an anesthesiologist assistant depends on state law. Some states permit supervised AA practice, while others have not yet established licensure pathways. 

Prospective AAs should consult their state’s medical licensing board or official regulatory agency for the most up-to-date information. It’s important to note that, unlike nurse anesthetists, AAs do not practice independently and must always be supervised by an anesthesiologist.

Data may change over time. Readers should verify current regulations with the appropriate state licensing board.

Anesthesia Team Members

Anesthesia care is delivered by a team of specialized professionals. Each brings unique expertise, ensuring that patients receive safe, effective anesthesia services. Primary team members and their training pathways include:

Anesthesiologist

Role: An anesthesiologist is a licensed physician (MD or DO) who leads the anesthesia team. They assess patients, develop individualized anesthesia plans, and oversee anesthesia delivery and recovery.
Training Requirements:

• Medical School: 4 years of medical education
• Residency: 4-year anesthesia residency covering multiple subspecialties (pediatric, cardiac, critical care)
• Optional Fellowship: 1–2 years in specialized areas (e.g., pain management, cardiac anesthesia)

Nurse Anesthetist

Role: A Certified Registered Nurse Anesthetist (CRNA) is an advanced practice registered nurse who may work independently or as part of an anesthesia team, depending on state laws. CRNAs perform pre-anesthetic evaluations, administer anesthesia, and oversee patient recovery.
Training Requirements:

• Nursing Degree: A Bachelor of Science in Nursing (BSN) or equivalent
• Critical Care Experience: Typically at least 1 year in a critical care setting
• Graduate Education: Completion of a Doctor of Nursing Practice (DNP) or Nurse Anesthesia Program (3–4 years)
• Certification: Passing the National Certification Examination for CRNAs

Anesthesiologist Assistant

Role: An anesthesiologist assistant (AA) practices under the direct supervision of an anesthesiologist, assisting with patient evaluations, anesthesia administration, and continuous monitoring.
Training Requirements:

• Undergraduate Education: A bachelor’s degree with coursework in sciences (biology, chemistry, physics) and mathematics
• Graduate Program: Completion of a 2-year Master of Science in Anesthesia (MSA) at an accredited institution
• Certification: Successful completion of the National Commission for Certification of Anesthesiologist Assistants (NCCAA) examination

Education and Training

Becoming an anesthesiologist assistant generally requires 6–8 years of post-secondary education. Specific steps typically include:

1. Earn a bachelor’s degree with a strong foundation in pre-medicine, such as the natural sciences and mathematics.
2. Take the MCAT or GRE, as required by individual programs.
3. Complete a Master of Science in Anesthesia at an accredited program (e.g., Purdue University, Saint Louis University, Emory University, University of Colorado, University of Missouri–Kansas City). Admission is competitive, and applicants with firsthand shadowing experience are often more attractive candidates.
4. Pass the NCCAA certification exam.
   Note: Requirements and costs vary. Always verify current admissions criteria and fees.

Ongoing Certification Requirements

To maintain certification, AAs must:

• Complete 50 hours of continuing education every two years
• Retake the NCCAA board exam every 10 years to ensure continued competency
  These requirements may evolve, so candidates should regularly check with the NCCAA for updates.

Skills to Succeed as an Anesthesiologist Assistant

Anesthesiologist assistants thrive when they possess a balanced skill set that includes:

Technical Skills: Sterile technique, pharmacology, and physiology

Interpersonal Skills: Clear communication, empathy, teamwork, and the ability to excel under pressure

Mindset: Patience, precision, and strong problem-solving abilities

Given the demanding nature of the role, AAs often work extended shifts (e.g., 12 hours) and may be on-call for 24–48 hours, depending on the healthcare facility’s needs.

Career Outlook and Salary Expectations

According to available data, the demand for anesthesiologist assistants may continue to rise as surgical procedures advance, and the need for specialized anesthesia care grows. Some estimates suggest a strong annual growth rate. Salary potential is also high, with many AAs reportedly earning over $200,000 per year. 

However, actual compensation can vary based on geographic location, employer type, and individual experience. Prospective AAs should review the latest data from reputable sources like the Bureau of Labor Statistics or professional organizations and consider regional factors when evaluating salary expectations.

Salary Variations by Location

Salary ranges differ by location. For example, in St. Louis, Missouri, some AAs may earn around $69 per hour (approximately $144,000 annually), while in Kansas City, Missouri, salaries can average about $63 per hour ($131,000 annually). 

These figures, drawn from ZipRecruiter data, are estimates and should be verified with current market research. Salaries can shift over time and may depend on factors like employer type, hospital size, and overall demand.

Comparison with Nurse Anesthetists (CRNAs)

In contrast to AAs, who always work under an anesthesiologist’s supervision, CRNAs may practice with greater autonomy in some states. Reflecting this added responsibility and independence, CRNAs often command higher pay. 

For example, CRNAs may earn around $97 per hour (or about $200,000 annually). 

These figures are approximate and should be confirmed with current market data.
