Anesthesiologists are perioperative physicians ("peri-" meaning "all-around") who provide medical care to patients before, during, and after surgical procedures. Anesthesiologists are responsible for delivering (or ensuring the delivery of) anesthesia safely to patients in virtually all health care settings, including all major R medical and tertiary care facilities. This includes a preoperative medical evaluation of each patient before surgery, consultation with the surgical team, creating a plan for the anesthesia tailored to each individual patient, airway management, intraoperative life support and provision of pain control, intraoperative diagnostic stabilization, and proper post-operative management of patients. Preparation of patients for emergency surgery are mandatory, essential, and critical skills that anesthesiologists have been trained to employ. Because anesthesiologists are physicians, in contrast to other anesthesia providers, they are able to utilize their extensive knowledge of human physiology and diseases to guide their decision making.

Historically in the United States there has been a shortage of anesthesiologists. In order to better serve the population, residency positions in anesthesiology for physicians have been steadily increasing the past several years. In addition, physicians supervise ACTs, or Anesthesia Care Teams, which are composed of a supervising physician with several certified registered nurse anesthetists (CRNAs) or anesthesiology assistants (AAs), working together to provide healthcare to the population. In other areas of the country, anesthesiologists work in what is deemed a "solo" or "MD/DO only" practice, during which they provide anesthesia in a "one on one" relationship with the patient.

As perioperative physicians, anesthesiologists also work in Intensive Care Units (ICUs), Post-Anesthesia Care Units (PACUs), Pain Clinics, Infusion Centers, and Ambulatory Surgical Centers. In recent years, a subspecialty has evolved. Some anesthesiologists pursue additional training in control of Chronic Pain and are certified as Pain Management specialists.

 

 

Patient informed consent is a fundamental ethical and legal principle and is considered essential to patient autonomy. The American Society of Anesthesiologists, the American Osteopathic College of Anesthesiologists, and other professional organizations, such as the American Association of Nurse Anesthetists, support the principle that patients should be fully informed regarding the manner in which their anesthetic will be administered.

Due to medications given before, during and after surgery, a patient may sometimes not remember interacting with his or her anesthesiologist and other members of the anesthesia care team. Therefore, patients should request to know, before surgery, the identity of their anesthesiologist as well as the identity of mid-level providers, such as nurse anesthetists or physician assistants, who will be involved in their anesthesia care. The anesthetic plan, as well as alternatives, risks, and benefits of the chosen anesthetic techniques, should be discussed with the patient prior to surgery. (This can be difficult or impossible in some situations, such as unconscious patients, confused patients, or extremely urgent cases. It may be possible to discuss matters with a patient's relative or carer).

Anesthesiologists are physicians (MD or DO) who have chosen to specialize in anesthesiology. Anesthesiologists in the United States must have completed an undergraduate college degree, including pre-medical requirements. Like other physicians, anesthesiologists complete four years of medical school. Physician training programs in the United States, without exception, require four years of residency training for board certification eligibility in the specialty of anesthesiology. An anesthesiology residency requires a one year medical or surgical internship followed by three years of anesthesiology training. Anesthesiology residency training in the U.S. encompasses the full scope of perioperative medicine, including pre-operative medical evaluation, management of pre-existing disease in the surgical patient, intraoperative life support, intraoperative pain control, post-operative recovery, intensive care medicine, and chronic and acute pain management. After residency, many anesthesiologists complete an additional fellowship year of subspecialty training in areas such as pain management, cardiac anesthesiology, pediatric anesthesiology, neuro anesthesiology, obstetric anesthesiology or critical care medicine.

The majority of Anesthesiologists in the United States are board-certified by a specialty medical board; either the American Board of Anesthesiology (ABA) or the American Osteopathic Board of Anesthesiology (AOBA). The ABA is a member of the American Board of Medical Specialties, while the AOBA falls under the auspices of the American Osteopathic Association. Both Boards are recognized by the major insurance underwriters in the U.S. as well as by all branches of the U.S. Uniformed Services. Board certification by the ABA involves both a written and an oral examination. AOBA certification requires the same, in addition to a practical examination with examining physicians observing the applicant actually administering anesthetics in the O.R.
