The Surgical Injury Severity Score (ISS) refers to the clinical scoring of the severity of a patient’s injuries, with a total score of 75, which includes minor injuries, serious injuries, severe injuries, and near-death types, with specific scores varying from one type to another. The Surgical Injury Severity Score ISS has a maximum score of 75, and if the patient’s ISS is less than 16, then it is a minor injury, if it is between 16 and 25, then it means it is a serious injury, and if the actual ISS is between 25 and 50, then it is a serious injury. However, if the ISS value is greater than 50 points, then it means that the patient’s condition has reached the level of near death, at this time, all the tissues and organs in the body will be seriously injured, the chances of survival are relatively low, and death may occur at any time. Therefore, patients should go to the hospital for examination in time after suffering from trauma, judge the severity of the disease through the ISS score, and actively cooperate with the doctor’s treatment to promote the recovery of the disease.
