Objective To search，evaluate and summarize the relevant evidence of the application of tourniquet in pre-hospital trauma treatment，and provide reference and evidence-based basis for pre-hospital treatment practice. Methods Chinese and English databases，guideline websites and professional association websites were searched. The retrieval period was from January 2015 to December 2023，and the literature types included clinical decision support，guidelines，systematic reviews，randomized controlled trials or quasi-experimental studies，and so on. 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. Conclusion The evidence summary of tourniquet application in pre-hospital trauma treatment is scientific and practical，which can provide evidence for pre-hospital trauma treatment practice，provide reference for popularization and training of first aid knowledge.
