To summarize the application effect of evidence-based nursing in the prevention and nursing of postpartum hemorrhage in obstetrics and guide its clinical application. Methods: The PIPOST method was used to define evidence-based problems comprehensively and carefully from six dimensions of population, intervention measures, control measures, outcome indicators, implementation places and time, so as to ensure the scientific and pertinence of evidence-based practice. Authoritative resources at home and abroad were searched systematically from top to bottom, according to the “6S” pyramid evidence model. The scope covers computer decision systems, tour websites, professional association websites, and well-known databases. The search evidence types are diverse, covering clinical decision-making, guidelines, systematic reviews, etc., and comprehensively covering the prevention of postpartum hemorrhage. The paper conducted a rigorous quality assessment of eligible literature using the AGREE II instrument to ensure the reliability and validity of the guidelines. Key information related to the prevention of postpartum hemorrhage was extracted, and finally graded according to the quality and reliability of evidence to provide a clear basis for evidence-based practice and assist medical staff to choose reasonable measures. Results: 13 pieces of literature were included, including 2 guidelines, 2 expert consensus, 1 evidence summary, 3 nursing and investigation studies, 1 systematic review, and 3 reviews. From 11 aspects, such as risk assessment, anemia management, health education, delivery mode selection, uterine hormone application, the third stage of labor management, labor control, vital signs monitoring, vaginal bleeding monitoring, uterine contraction monitoring and psychological care, 23 best pieces of evidence for postpartum bleeding prevention and care were systematically summarized. Conclusion: Clinical managers shoulder important responsibilities and need to strengthen the fine management of the emergency treatment process of postpartum massive hemorrhage. Standardized and systematic training for medical staff should be vigorously promoted. Through a variety of training formats and specialized courses, the professional competence and practical skills of clinical medical staff in the prevention and treatment of postpartum hemorrhage should be effectively enhanced. In actual clinical work, it can more effectively deal with postpartum massive bleeding, reduce the incidence of postpartum massive bleeding as much as possible, significantly reduce its mortality, and provide a more solid and reliable guarantee for the life and health of pregnant women. Significance: Through systematic retrieval and integration of domestic and foreign authoritative resources, 23 best pieces of evidence of postpartum hemorrhage prevention and nursing were summarized to help nurses better conduct the nursing assessment, nursing diagnosis and nursing planning, formulate scientific and effective nursing measures, improve working methods, and solve existing and potential problems of patients, so as to promote the scientific and effective clinical nursing practice. The scope of application: It is applicable to women with bleeding tendencies, to prevent postpartum bleeding, and to help medical workers develop scientific and effective medical care measures.
