A high-risk surgery is generally defined as a surgical procedure with a significant chance of mortality. According to research, a high-risk procedure is one with a mortality rate greater than 5%. Additionally, surgical patients with a predicted mortality rate exceeding 20% are considered "extremely high-risk".
In summary:
- High-Risk Surgery: Mortality rate > 5%
- Extremely High-Risk Surgery: Mortality rate > 20%
| Risk Category | Mortality Rate |
|---|---|
| High-Risk | > 5% |
| Extremely High-Risk | > 20% |
