Two researchers respectively evaluated the quality of the literature and extracted the evidence. Results A total of 16 literatures were included，including a clinical decision，a guideline and 3 expert consensuses，4 systematic reviews，3 randomized controlled trials and 4 quasi-experimental studies. Twenty-two pieces of evidence were summarized from 12 aspects，including indications for tourniquet use，contraindications for tourniquet use，rapid assessment of bleeding severity，selection of tourniquet，location and method of dressing，effective criteria and pressure settings of tourniquets，time settings，dynamic evaluation，clear marking，removal，monitoring and re-evaluation of tourniquet，and recording.
