According to the Guide, which procedure is defined as one that "penetrates and exposes a body cavity, produces substantial impairment of physical or physiologic functions, or involves extensive tissue dissection or transection"?

• A. Any procedure with anesthesia
• B. Minor surgery
• C. Major surgery
• D. Aseptic surgery

Answer: (C)

In the Guide, procedures are categorized by how invasive they are. The definition given—penetrating and exposing a body cavity, producing substantial impairment of physical or physiologic functions, or involving extensive tissue dissection or transection—describes a high level of invasiveness and impact on the organism. That combination of penetrating a body cavity, causing significant functional impairment, or requiring extensive tissue work clearly marks a major surgical procedure. Procedures that are less invasive don’t meet these thresholds; minor surgery involves limited tissue manipulation and minimal impairment. Aseptic surgery talks about maintaining sterile technique, not the degree of invasiveness. A procedure performed under anesthesia isn’t a defining criterion by itself, since anesthesia can accompany both minor and major procedures; the defining factors are the invasiveness and the physiological impact. Therefore, the category that fits this description is major surgery.
