An SRNA is a Student Registered Nurse Anesthetist, a registered nurse currently enrolled in a graduate program to become a Certified Registered Nurse Anesthetist (CRNA). During their training, SRNAs learn to administer anesthesia for surgeries and procedures under direct supervision, completing a minimum of 600 anesthetic cases and 2,000 clinical hours before they can sit for their certification exam.
What SRNAs Do in Training
SRNAs provide the same types of anesthesia care that a fully credentialed CRNA does, but always under supervision. Their clinical work includes placing breathing tubes, managing ventilators, starting and adjusting anesthesia medications, and monitoring patients throughout surgery. They assess patients before procedures, develop anesthesia plans, and manage pain afterward.
Supervision rules are strict. Under Medicare guidelines, one attending anesthesiologist can supervise no more than two SRNAs working independently at any given time. A CRNA working alongside an SRNA counts as a single provider for supervision purposes. SRNAs are never supervised by medical residents. Before every case, the student is expected to contact the supervising attending to discuss the anesthetic plan.
How to Become an SRNA
You can’t enter a nurse anesthesia program straight out of nursing school. The path starts with earning a Bachelor of Science in Nursing, passing the NCLEX-RN, and then working in a critical care setting for at least one year full-time (or the part-time equivalent). That critical care experience is non-negotiable because it builds the clinical judgment SRNAs need from day one of their program.
The accrediting body defines “critical care” as a unit where nurses routinely manage invasive hemodynamic monitors (like arterial lines and pulmonary artery catheters), mechanical ventilation, cardiac assist devices, and IV medications that directly affect heart function and blood pressure. Common qualifying units include surgical ICUs, cardiac ICUs, medical ICUs, pediatric ICUs, and neonatal ICUs. Nurses with experience in other settings may qualify if they can demonstrate competence managing unstable patients, invasive monitoring, ventilators, and critical care medications.
The Doctoral Degree Requirement
Nurse anesthesia has moved entirely to doctoral-level education. As of January 1, 2025, all graduates of accredited nurse anesthesia programs must hold a doctoral degree, either a Doctor of Nursing Practice (DNP) or a Doctor of Nurse Anesthesia Practice (DNAP). This transition began years earlier: students accepted into programs on or after January 1, 2022 were already required to graduate with a doctorate. Master’s-level entry is no longer an option.
Most full-time programs run about 36 months, regardless of whether students enter with a bachelor’s or a master’s degree. The curriculum combines graduate coursework in advanced pharmacology, anatomy, physiology, and anesthesia principles with progressively independent clinical rotations. Rush University’s program is typical of this three-year, full-time structure.
Clinical Benchmarks Before Certification
The National Board of Certification and Recertification for Nurse Anesthetists (NBCRNA) sets minimum clinical requirements that every SRNA must meet before applying to take the National Certification Examination (NCE). These include at least 600 total anesthetic cases and 2,000 clinical hours. Many programs exceed these minimums, with some requiring around 2,500 clinical hours.
Those 600 cases span a range of surgical specialties, patient populations, and anesthesia techniques. SRNAs gain experience with general anesthesia, regional anesthesia (like spinal and epidural blocks), and sedation. They work with pediatric, geriatric, obstetric, and trauma patients. The goal is to produce a graduate who can independently manage anesthesia across nearly any clinical scenario.
After Training: The CRNA Career
Once an SRNA passes the NCE, they become a CRNA. The career outlook is strong. The Bureau of Labor Statistics projects 9% job growth for nurse anesthetists between 2024 and 2034, which is faster than average for all occupations. The median annual salary for CRNAs was $223,210 as of May 2024, making it one of the highest-paying nursing specialties in the country.
CRNAs practice in hospitals, surgical centers, dental offices, pain management clinics, and military settings. In many rural and underserved areas, they serve as the primary anesthesia providers. The level of independence varies by state: some states allow CRNAs to practice without physician supervision, while others require a collaborative agreement with an anesthesiologist or surgeon.
