Medically Reviewed.Last updated on 05/18/2026.

A CRNA (certified registered nurse anesthetist) is a registered nurse who has specialized training in anesthesia. They can give anesthesia for procedures and surgeries. They help take care of you before, during and after your surgery.

What Is a CRNA?

A CRNA (certified registered nurse anesthetist or “nurse anesthetist”) is a healthcare provider who gives anesthesia and other medications, like sedatives. They also take care of and monitor you while you’re under anesthesia and recovering from it. They care for people of all ages.

Anesthesia is a medical treatment that keeps you from feeling pain during procedures or surgery. There are many forms of it.

A CRNA is an advanced practice registered nurse (APRN). They have a total of seven to 10 years of training.

CRNAs first start as registered nurses. They must work in an intensive care unit (ICU) for at least one year before attending an accredited nurse anesthesia program. Upon graduating from the program and passing a national certification exam, some CRNAs choose to do a fellowship in a specialized area of anesthesiology. One example is chronic pain management.

This educational pathway is different from what anesthesiologists do. But both healthcare providers can safely and expertly provide anesthesia.

What is an APRN?

Advanced practice registered nurses (APRNs) are registered nurses (RNs) with a graduate-level degree. They specialize in a specific medical role. APRNs have training and certification to assess, diagnose and manage medical issues. They can also order tests and prescribe medications.

Types of APRNs include:

What do nurse anesthetists do?

CRNAs help take care of you before, during and after procedures involving anesthesia or sedation — just like an anesthesiologist. They work alongside surgeons, dentists and other specialists.

The roles of a CRNA include:

  • Educating you before and after you get anesthesia
  • Identifying possible risks of undergoing anesthesia, including allergic reactions and issues related to health conditions
  • Providing precise dosages of anesthesia
  • Monitoring your vital signs during surgery
  • Managing your medical conditions during surgery
  • Giving fluids, blood products and medications to support your bodily functions while you’re under anesthesia
  • Making sure you wake up and recover from anesthesia OK
  • Giving epidurals to manage the pain of childbirth
  • Being part of a team of specialists who help you manage chronic pain

When would I see one?

A nurse anesthetist may care for you any time you need anesthesia. This can range from medical or dental procedures to chronic pain management.

CRNAs are often the sole anesthesia providers in hospitals in rural parts of the United States. They’re also the main provider of anesthesia to those who serve in the U.S. armed forces.

What can I expect during an appointment with a nurse anesthetist?

If you’re going to have a procedure with general anesthesia, you’ll meet with a CRNA (or anesthesiologist) before it. They’ll make sure you’re fit for surgery.

They’ll ask questions about your:

  • Overall health
  • Health conditions, like heart disease, diabetes or asthma
  • Medications and supplements
  • Allergies
  • Your personal and biological family history of anesthesia issues

They’ll also do a physical exam and review any tests you’ve had to prepare for the procedure.

Where do CRNAs work?

Nurse anesthetists can work in several medical settings, including:

  • Hospital operating rooms (ORs)
  • Postanesthesia recovery rooms (PACUs)
  • Emergency rooms (ERs)
  • Outpatient surgery centers
  • Labor and delivery units
  • Physicians’ offices
  • Dentists’ offices
  • Ketamine clinics

A note from Cleveland Clinic

Facing surgery or an invasive procedure can be stressful. Know that your certified registered nurse anesthetist (CRNA) has specialized knowledge and skills to make sure you’re safe during the surgery. Don’t hesitate to ask questions. They can help you feel more comfortable and confident about the process.
