This document discusses the different types of anesthesia - moderate sedation, monitored anesthesia care (MAC), and general anesthesia - and which procedures each is typically used for, such as colonoscopies, hand surgery, or heart surgery. It notes the benefits of anesthesia including pain relief and safety monitoring, but also risks like heart attack, stroke, or death which can be increased by preexisting conditions. The document advises discussing personal health history and concerns with your anesthesiologist to determine the best option.
