Nurse Anesthetist

A nurse anesthetist is an advanced practice nurse who administers anesthesia for surgery or other medical procedures. They are involved in the administration of anesthesia in a majority of countries, with varying levels of autonomy. Nurse anesthetists provide all services of anesthesia for patients before, during, and after surgery. Certified Registered Nurse Anesthetists, (CRNA) are concerned with the safe administration of anesthesia delivery and work within a diverse team. They are also concerned with patient advocacy, safety and professional development. In some localities, nurse anesthetists provide anesthesia to patients independently; in others they do so under the supervision of physicians. In the United States, the physician may be an anesthesiologist, surgeon, or podiatrist. The International Federation of Nurse Anesthetists was established in 1989 as a forum for developing standards of education, practice, and a code of ethics.

History of CRNAs

In the United States, nurse anesthetists are called Certified Registered Nurse Anesthetists (CRNAs). CRNAs account for approximately half of the anesthesia providers in the United States and are the main providers of anesthesia in rural America.

Nurses have been providing anesthesia care to patients since the American Civil War. Nurse anesthetists are considered an essential role to the health care workforce. They provide pain management and emergency services, including airway management and blood and fluid resuscitation, which was very important to patients in the Civil War. Depending on the local system of healthcare, they participate only during the operation itself, or may also be involved before and after (for preanesthetic assessment and immediate postoperative management). The National Association of Nurse Anesthetists professional association was established by Agatha Hodgkins in 1931. It was renamed the American Association of Nurse Anesthetists in 1939. The group established educational institutions for nurse anesthetists in 1952, and established the CRNA certification in 1957. AANA continuing education was established in 1977. As of 2011, some 92% of CRNAs in the U.S. were represented by the AANA.

Scope of practice rules vary between healthcare facility and state. Before 2001, Medicare required that physicians supervise CRNAs in the administration of anesthesia. In 2001, Medicare's rules changed, allowing individual states to decide whether CRNAs may administer anesthesia without physician supervision. In the absence of a state requirement that physicians supervise CRNAs, individual healthcare facilities decide. CRNA organizations have lobbied in many states for the ability to practice without physician supervision; these efforts are opposed by physician groups. In 2011, sixteen states granted CRNAs autonomy, allowing them to practice without physician oversight. In 2017, there were 27 states in which CRNAs could independently practice (that is, "without a written collaborative agreement, supervision or conditions for practice"). In 2020, there was no physician supervision requirement for nurse anesthetists in ambulatory surgical facilities in 31 states In states that have opted out of supervision, the Joint Commission and CMS recognize CRNAs as licensed independent practitioners. In states requiring supervision, CRNAs have liability separate from supervising practitioners and are able to administer anesthesia independently of anesthesiologists.

Education

A nurse anesthetist will need to complete at least three years of higher education, beyond the bachelor's of nursing degree. Many CRNA school applicants are also MSN (Masters in Nursing) holders in leadership or even a clinical realm like Nurse Practitioner (NP).

Before becoming a nurse anesthetist, one must complete a Bachelors of Science in Nursing degree. A minimum of one year of full-time work experience as a registered nurse in a critical care setting is required before applying to CRNA school. The average experience of RNs entering nurse anesthesia educational programs is 2.9 years. Nurse anesthetists are required to attend accredited educational programs covering all areas of anesthesia. This education provides training about the anesthetics needed for patients in any type of procedure or surgery. After completing an accredited program, CRNAs must pass a national certification exam to acquire this designation. It is important to have the best education for this field for the significance of anesthesia. By 2025 the Council on Accreditation, the organization which accredits nurse anesthetist programs, will require all graduating CRNAs to be doctorate-prepared.

Salary

According to the U.S. Bureau of Labor Statistics, a CRNA salary is around $181,040. Salaries within the US vary by state. Overall employment for nurse anesthetists and other medical professions is projected to grow 45 percent from 2020 to 2030.

Work environment

CRNAs typically work in healthcare settings such as emergency rooms, intensive care units, and operating rooms. Their environment is with medical and surgical teams with procedures that can occur anytime. Some partnerships they work with are anesthesiologists, dentists, surgeons, and other medics in serving patients who need of receiving anesthesia. Nurse anesthetists are an essential part of everyday medical facilities. The need of CRNAs is anticipated to grow.

Skills and procedures

Nurse anesthetists work with anesthesiologists, surgeons, anesthesiologist assistants, anesthesia technicians, and others. CRNAs communicate with the surgeon and interdisciplinary team to design an anesthesia plan for a patient. Some procedures that nurse anesthetists offer include:
*Evaluation of the patient prior to anesthesia
*Physical assessment and pre-operative teaching before the anesthesia
*Administering anesthesia
*Airway management

Roles and responsibilities

CRNAs have important roles when it comes to patient care. They need to meet all the patients' standards and help ensure the patient is in good condition before receiving an anesthesia plan. Some of the roles and responsibilities a CRNA need to require for this position include:
*Bedside manner
*Record-keeping skills
*Communication skills
*Teamwork with other nurses and doctors
*Inhaled anesthesia administration
*Administration of blood and medication
*Epidural placement
*Placement of arterial and central lines

The CRNA profession requires an understanding, accurate, and responsible attitude to work this position. You must have strong communication skills with the patient and your team to become a CRNA. The freedom of a nurse anesthetist is expanded compared to an RN that allows you to oversee the patient and with your team.

Nurse anesthetist vs. anesthesiologist

Nurse anesthetist and physician anesthesiologists have certain distinctions, however they share many similarities. Certified Registered Nurse Anesthetists are nurses who have specialized training to perform anesthesia. In comparison, an anesthesiologist is a trained physician who specializes in anesthesia.

Terminology

The AANA recognizes ''Certified Registered Nurse Anesthetist'', ''CRNA'', ''nurse anesthetist'', and ''nurse anesthesiologist'' as equivalent titles. The use of ''nurse anesthetist'' is substantially more common than the use of ''nurse anesthesiologist;'' terms ''anesthesia nurse'' and ''anesthetist nurse'' are unheard of.

Use of the term ''nurse anesthesiologist'' has been criticized by those who argue that the term ''anesthesiologist'' should be limited to medical doctors. For example, groups representing anesthesiologists and other medical doctors, such as the American Medical Association (AMA) and American Society of Anesthesiologists (ASA), oppose the use of this phrase to describe CRNAs and call it misleading.

In 2021, after a year-long rebranding effort, the American Association of Nurse Anesthetists changed its name to the American Association of Nurse Anesthesiology. The name change was condemned by physician groups, including the AMA, ASA, American Board of Anesthesiology, American Board of Medical Specialties, and American Osteopathic Association. Physicians' organizations said that the name change was "title misappropriation" that was deceptive, misleading to patients, and cause confusion in care settings.

In 2021, the New Hampshire Supreme Court upheld a decision by the New Hampshire Board of Medicine that blocked nurse anesthetists from identifying themselves as anesthesiologists and limited use of the title to MDs and DOs specializing in anesthesiology.

United States

A Certified Registered Nurse Anesthetist (CRNA) is a nurse anesthetist who is licensed to administer anesthesia in the United States. CRNAs account for approximately half of the anesthesia providers in the United States and are the main providers of anesthesia in rural America. Historically, nurse anesthetists have been providing anesthesia care to patients since the American Civil War and the CRNA credential came into existence in 1956. CRNA schools issue a master's or doctorate degree to nurses who have completed a program in anesthesia, which ranges from two to three years in length. Scope of practice and practitioner oversight requirements vary between healthcare facility and state, with 25 states and Guam granting complete autonomy as of 2024.In states that have opted out of supervision, the Joint Commission and CMS recognize CRNAs as licensed independent practitioners. In states requiring supervision, CRNAs have liability separate from supervising practitioners and are able to administer anesthesia independently of physicians, such as anesthesiologists.

Europe

France

The specialty of a non-medical anesthesia professional did not exist before WWII in France. After WWII, the Hôpital de Saint-Germain-en-Laye offered practical training for paramedics and nurses. Until the 1970s, many general hospitals had no appointed physician anesthesiologists. In 1960, the Ministry of Health commissioned a certificate of competence as infirmier aide anesthésiste (IAA) for nurse anesthetists. From then onward, only specialized nurses were allowed to administer anesthesia independent of the surgeon. Similar to the situation in the USA, anesthesiologists tried to distance themselves from anesthetists. In 1974, the Professional Association of Physician Anesthesiologists submitted a Bill in order to extinguish the profession, but the bill was withdrawn and a campaign was started for the legal recognition oh the nurse anesthetist profession. In the 1980s, the profession of nurse anesthetist was nationally recognized and given the new title infirmier spécialisé en anesthésie-réanimation (ISAR). This was accompanied by an official training program and state diploma. Training to become an NA requires at least two years’ experience as a general nurse, followed by success at an examination at the end of two years’ special training in an anaesthetic nurse school teaching the acquisition of the national certification.

United Kingdom

The British Army had only ever experienced anaesthesia delivered by
doctors and the arrival at the “front” of USA NAs astonished them.
The great skill and care that was displayed by these NAs soon caused
amazement to yield to admiration and, in 1918, classes were formed
for British nursing sisters and these nurses started performing duties
in various hospitals.
Between the First and Second World Wars, operating theatre attendants (OTAs) or theatre porters/orderlies were helping the surgeons and anesthesiologists. After WWII, the OTA changed their names to operating theatre
technician (OTT) and extended their role following the model used
in the military. OTTs became the assistant to the anesthesiologist and were responsible for the anaesthesia equipment and assisted the anesthesiologist during
complex tasks including transfusion, resuscitation and endotracheal
intubation. Besides the OTTs, an anaesthetic nursing service was established
during the eighties. These relatively few registered anaesthetic
nurses could take more responsibility in comparison to the OTT
and were, for example, allowed to administer drugs and to set up
intravenous infusions.
The prospect of training non-medical anaesthesia professionals to administer anaesthesia had
been suggested, intermittently, for several years, but has been resisted
strongly by the Association of Anaesthetists of Great Britain and Ireland

In Europe, only Belgium and the UK have relied entirely
on physician-based anaesthesia but, in recent years, experimental
training schemes for non-medical graduates have been introduced to
address the staffing crisis problem

Germany

Until after WWII, the surgeons were responsible for both operating and supervising the
nurse who administered anesthesia. Anesthesia was a subspeciality
of the surgical department. Because surgery became increasingly
more complex, the Facharzt für Anästhesie (anaesthesia physician)
was introduced and the German Society for Anesthesiology and
Intensive Care was founded in 1953. In the 1960s, nurse anesthetists were utilized as a rescue solution due to a severe shortage of anaesthesiologists. NAs administered anesthesia under supervision of the surgeon and filled in for the shortage of anesthesiologists. Almost from the
beginning, the German anesthesiologists worked together with an
anesthesia assistant. After completing their nursing program, to become a
nurse anesthetist (NA), the nurses were trained for two more years
within anesthesia and intensive care. It
was not until 1992 that enough anesthesiologists were trained to
abandon the NA concept. In 2004, the German private HELIOS hospitals started, once again,
to train nurses to become Medizinische Assistent fur Anästhesie
(MAfA) comparable to the NA. To become a MAfA, nurses first
had to work for at least two years in an anesthesia or intensive care
department, followed by one year of practical training in anesthesia
(400 hours). The training involved 200 hours of theoretical training
and three days of training in an anesthesia simulator. The HELIOS
hospitals initiated this MAfA training so that they could introduce
parallel anesthesia, that is, one anesthesiologist giving anesthesia
in two different theatres. In every OR, a MAfA would administer
the anesthesia and receive supervision from the anesthesiologist.
Sadly, three weeks after certification of one of the first MAfAs, a
fatal complication occurred in a healthy 18-year-old male while a
MAfA was giving anesthesia. After this incident, much criticism was
levelled by the National Physicians’ Board in Germany and MAfA
training was stopped immediately.

Scandinavia

Initially, nurses took a great deal of responsibility for the practice of
Anaesthesia in Scandinavia and worked in a fashion similar to that pertaining many
other countries, under the leadership of a surgeon. Some prominent
surgeons, in the mid-19th century, realised that developments in
surgery required a parallel, appropriate development in anaesthesia.
Scandinavian nurses developed general anaesthesia into a craft
that required high levels of qualification characterised by expert
knowledge, observational expertise and skills. Formal education
of NAs has taken place since 1962 in Sweden, 1963 in Finland and
1965 in Norway. National societies of NAs were founded in 1960 in
Sweden, 1965 in Norway and 1966 in Finland.

The Netherlands

Despite a gradual increase in the number of
anaesthesiologists responsible for anaesthesia, in the first half of
the 20th century, nurses and religious nuns largely took care of the
anaesthetic aspects of an operation under supervision of a surgeon.
Since 1966, NAs were officially trained by the
Nationale Vereniging van Ziekenhuizen (National Society of
Hospitals). According to a survey held in 1969, a shortage of 80–100
anaesthesiologists existed in the Netherlands. This deficit was solved
by allowing NAs to administer anaesthesia but only under direct
supervision of the surgeon. In 1970, the Dutch National Health
Council stated that every anaesthesiologist needed the help of a
qualified NA. The flexible, two-table system was henceforth only
allowed if an NA stayed with the patient throughout the operation.
During the end of the 1960s and early 1970s NAs were exclusively
supervised by anaesthesiologists and no longer by surgeons. It was
not until 1984 when the training of NAs received approval from the
Ministry of Health.

Africa

The majority of people living in African countries do not have access to safe and affordable anesthesia, analgesia, and surgical care. There are 30 distinct pathways to train as an anesthesia provider in Africa, defined as the unique combination of entry qualification, duration, and qualification awarded. A majority (73%) of countries in Africa rely on non-physician anesthesia providers (NPAP) or some form of non-physician qualification in order to practice anesthesia. Most countries had both physician and non-physician training routes. Of all the NPAP training pathways, 60% required a nursing background for entry, 14% required either nursing or other clinical experience, 12% specifically required clinical experience other than nursing, and 14% required no prior clinical experience. Physicians provided clinical supervision and curriculum teaching for NPAP programs less than half the time. Liberia, Niger, Togo, Congo, Central African Republic, South Sudan, and Eritrea currently only train nurse anesthetists in the administration of anesthesia.

Asia

After 1869, Japanese medicine came under German
influence such that regional anaesthesia was dominant over general
anaesthesia. It was not until 1950, when Meyer Sakland from USA
conveyed modern knowledge of anaesthesia to the Japanese, that
general anaesthesia became popular and developed rapidly. Until
now, there have been no non-medical anaesthesia professionals
in Japan; however, recently, the debate has started regarding its
potential introduction into Japanese operating theatres. In 2010, a
first, important step was taken by starting an exchange education
programme with the USA. In China, the history is not much different. Some early pioneer
anaesthesiologists came back from the USA bringing with them the
message of anaesthesia, but it was not till the early 1950s that modern
anaesthesia was introduced only to come to an abrupt halt during
the Cultural Revolution when only acupuncture and
Chinese herbal medicine were encouraged. After 1979, anaesthesia
developed rapidly and achieved independence from surgery by 1989.
The role of non-medical anaesthesia professionals is very limited in
China.

Australia

In outback
Australia, anaesthesia was frequently administered by non-medical
assistants, attracting strong criticism by the medical establishment.
The standard pattern of anaesthesia administration in the early 1900s in
Australian cities was that the general practitioner (GP) referring the
patient to the surgeon would administer the anaesthetic. In 1934, anaesthesia physicians became
organised industrially and educationally very early as the Australian
Society of Anaesthetists (ASA), and an early principle was that, whenever possible, one
anaesthetist (and not an assistant) would care for and supervise one
patient and that the anaesthetised patient would receive priority
over all other activities. As nursing shortages were widespread, there was
little scope for branching out into anaesthesia administration; nurses
gravitated towards operating theatre scout and scrub duties. While
the concept of non-medical nurse practitioners surfaced and was
successful in the different states of Australia and in New Zealand, the non-medical
anaesthesia professional has been more prevalent within the sub-
branches of the anaesthesia services.
Physicians became the sole administrators of anaesthesia in other parts of the former British
Empire – in Singapore, Malaya, Hong Kong, India, Malta, Aden and
Gibraltar.
