The mission of the American Board of Anesthesiology (ABA) is to advance the highest standards of the practice of anesthesiology. As the certifying body for anesthesiologists since 1938, the ABA is committed to partnering with physicians to advance lifelong learning and exceptional patient care. The Board administers primary and subspecialty certification exams as well as the Maintenance of Certification in Anaesthesiology Program (MOCA), which is designed to promote lifelong learning, a commitment to quality clinical outcomes and patient safety. Based in Raleigh, N.C. ABA is a nonprofit organisation and a member board of the American Board of Medical Specialities.
Anesthesia is a treatment using drugs called anesthetics. These drugs keep you from feeling pain during medical procedures. Anesthesiologists are medical doctors who administer anesthesia and manage pain. Some anesthesia numbs a small area of the body. General anesthesia makes you unconscious (asleep) during invasive surgical procedures.
Anesthesia is a medical treatment that keeps you from feeling pain during procedures or surgery. The medications used to block pain are called anesthetics. Different types of anesthesia work in different ways. Some anesthetic medications numb certain parts of the body, while other medications numb the brain, to induce a sleep through more invasive surgical procedures, like those within the head, chest, or abdomen.
Anesthesia temporarily blocks sensory/pain signals from nerves to the centers in the brain. Your peripheral nerves connect the spinal cord to the rest of your body.
If you’re having a relatively simple procedure like a tooth extraction that requires numbing a small area, the person performing your procedure can administer the local anesthetic. For more complex and invasive procedures, your anesthetic will be administered by a physician anesthesiologist. This medical doctor manages your pain before, during and after surgery. In addition to your physician anesthesiologist, your anesthesia team can be comprised of physicians in training (fellows or residents), a certified registered nurse anesthetist (CRNA), or a certified anesthesiologist assistant (CAA).
The anesthesia your healthcare provider uses depends on the type and scope of the procedure. Options include:
Local anesthesia: This treatment numbs a small section of the body. Examples of procedures in which local anesthesia could be used include cataract surgery, a dental procedure or skin biopsy. You’re awake during the procedure.
Regional anesthesia: Regional anesthesia blocks pain in a larger part of your body, such as a limb or everything below your chest. You are can be conscious during the procedure, or have sedation in addition to the regional anesthetic. Examples include an epidural to ease the pain of childbirth or during a cesarean section (C-section), a spinal for hip or knee surgery, or an arm block for hand surgery.
General anesthesia: This treatment makes you unconscious and insensitive to pain or other stimuli. General anesthesia is used for more invasive surgical procedures, or procedures of the head, chest, or abdomen.
Sedation: Sedation relaxes you to the point where you will have a more natural sleep, but can be easily aroused or awakened. Light sedation can be prescribed by the person performing your procedure, or together with a regular nurse, if they both have training to provide moderate sedation. Examples of procedures performed with light or moderate sedation include cardiac catheterization and some colonoscopies. Deep sedation is provided by an anesthesia professional because your breathing may be affected with the stronger anesthetic medications, but you will be more asleep than with light or moderate sedation. Although you won’t be completely unconscious, you are not as likely to remember the procedure.
