Surgery

Surgical specialties employ operative treatment. In addition, surgeons must decide when an operation is necessary, and also treat many non-surgical issues, particularly in the surgical intensive care unit (SICU), where a variety of critical issues arise. Surgery has many subspecialties, e.g. general surgery, trauma surgery, cardiovascular surgery, neurosurgery, maxillofacial surgery, orthopedic surgery, otolaryngology, plastic surgery, oncologic surgery, vascular surgery, and pediatric surgery. In some centers, anesthesiology is part of the division of surgery (for logistical and planning purposes), although it is not a surgical discipline.

Surgical training in the U.S. requires a minimum of five years of residency after medical school. Sub-specialties of surgery often require seven or more years. In addition, fellowships can last an additional one to three years. Because post-residency fellowships can be competitive, many trainees devote two additional years to research. Thus in some cases surgical training will not finish until more than a decade after medical school. Furthermore, surgical training can be very difficult and time consuming. A surgical resident's average work week is approximately 75 hours. Some subspecialties of surgery, such as neurosurgery, require even longer hours, and utilize an extension to the 80 hour regulated work week, allowing up to 88 hours per week. Many surgical programs still exceed this work hour limit. Attempts to limit the amount of hours worked has been difficult because of the large volume of patients who require surgical care, the limited amount of resources (including a shortage of people willing to enter into surgery as a career)^[12], the need to perform long operations and still provide care to all pre- and post-operative patients, and the need to provide constant coverage in the OR, ICU, and ER.
