Anesthesiology is the field of medicine primarily focused on bringing upon the patient a state of anesthesia, which is characterized by a reversible loss of consciousness, analgesia, amnesia, and muscle relaxation by using pharmacological agents known as anesthetics. Other areas of focus in this field include management of patients in the ICU, management of chronic pain, and palliative care.

Due to the effects of intravenous anesthetics on breathing, the anesthesiologist should also be proficient in securing the patient’s airway and providing adequate ventilatory support. For optimal understanding, the medical student should be familiarized with the physiology of the cardiovascular and respiratory systems (especially the mechanics of ventilation and lung volume), basics of acid-base balance, pathophysiology of pain, basic concepts of pharmacology, and commonly used intravenous, local, and inhaled anesthetics.

Anesthesiology-related functions most commonly play out in the operating room, where anesthesiologists work in conjunction with surgeons to provide optimal care. Apart from operative care, anesthesiology has several applications in clinical, critical, and end-of-life care. For the general practitioner, a good understanding of the basic concepts of anesthesiology proves beneficial for the basic management or prevention of pain during minor procedures.
