<unk> principle The<unk> is the period of time immediately after a traumatic injury during which there is the highest likelihood that prompt medical and surgical treatment will prevent death. While initially defined as an<unk> , the exact time period depends on the nature of the injury and can be more than or less than this duration. It is well established that the person's chances of survival are greatest if they receive care within a short period of time after a severe injury; however, there is no evidence to suggest that survival rates drop off after 60 minutes. Some have come to use the term to refer to the core principle of rapid intervention in trauma cases, rather than the narrow meaning of a critical one-hour time period.
