RT Book, Section A1 Wachter, Robert M. SR Print(0) ID 56250378 T1 Chapter 5. Surgical Errors T2 Understanding Patient Safety, 2e YR 2012 FD 2012 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-176578-7 LK accessmedicine.mhmedical.com/content.aspx?aid=56250378 RD 2024/04/19 AB More than 20 million people undergo surgery every year in the United States alone. In the past, surgery could be extremely dangerous, in part because of the risks of the surgery itself (bleeding, infection), and in part because of the high risks of anesthesia. Because of major safety improvements in both of these areas, surgeries today are extremely safe, and anesthesia-related deaths are rare.1 Advances in surgery, anesthesia, and postoperative care have led to major declines in mortality in disorders generally treated by surgery, such as diseases of the gallbladder and appendix.2
