Anesthesiologists are highly skilled medical doctors (M.D. or D.O.) who specialize in the field of Anesthesiology. As physicians with significantly longer and more extensive training than other classifications of anesthesia practitioners, anesthesiologists are the most qualified to make anesthesia related pre-operative medical decisions. Anesthesiologists are primarily responsible for the safety and well-being of patients before, during and after surgery. This may include placing them in the state of controlled unconsciousness called “general anesthesia”, the provision of “regional anesthetics” where only a portion of the body is made numb, or administering sedation when indicated for the relief of pain or anxiety. These anesthetics provide continuous pain relief and sustain patients’ critical life functions as they are affected throughout surgical, obstetrical or other medical procedures.
