What happens during my surgery?
Your anesthesiologist is personally responsible for your comfort and well-being. Your anesthesiologist leads the anesthesia care team to monitor as well as manage your vital body functions during your surgery. Your anesthesiologist is also responsible for managing medical problems that might arise related to surgery as well as any chronic medical conditions you may have, such as asthma, diabetes, high blood pressure or heart problems. A member of your anesthesia team will be with you throughout your procedure.
