Abstract: Objective: To search and summarize the relevant evidence on the prevention and management of Obstructive Sleep Apnea (OSA) in pregnant women, and to provide a scientific basis for medical staff to practice for this population. Methods: According to the "6S" evidence model, the relevant literature was systematically searched in computerized decision-making support systems, domestic and international guideline networks, websites of related academic societies and databases from the inception of databases to November 1st, 2024. Researchers trained in evidence-based nursing evaluated the methodological quality of the included literature and collected the evidence after data extraction. Results: A total of 16 literature was included, including five clinical decision-making documents, one guideline, six systematic reviews, two expert consensus statements, one best practice recommendation and one randomized controlled trial. Twenty-three pieces of evidence in five areas were summarized and extracted, including timing of screening, risk identification, assessment and diagnosis, pregnancy management and health education support. Conclusion: The evidence summarized in this study can provide a basis for clinical healthcare professionals in the development of management protocols and practice for pregnant women. However, the application of the evidence should be tailored to the specific clinical context.
