The so-called tuauma index (TI) score was put forward by kirkpatrick and others in 197 1 year. Kirkpatrick, Jirik and Nana Ogawa summarized the injuries according to the injured position and degree, and described them with numbers, mainly selecting the injured position, injury type and circulation. 1, 3, 5 or 6 points, according to their abnormal degree, add up to get the integral (5-24), which is the TI value. The greater the score, the more serious the injury, and most of the injuries with an index above 17 are multiple injuries. TI value of 5-7 is divided into minor injuries; 8- 17 is divided into moderate and severe injuries; 17-20 was classified as seriously injured with high mortality; ≥2 1 was classified as critical injury, and the mortality rate increased sharply; After 29 o'clock, 80% died within 1 week.

Among them, the scoring method under cyclic state can be seen in the third article on cyclic state below, and all three are mentioned.
