Abstract: Objective: To systematically evaluate the literature on thirst management interventions for ICU patients, providing evidence-based recommendations to guide nurses in selecting appropriate interventions for managing thirst in this patient population. Methods: The review followed the methodological framework for scoping reviews outlined by the Joanna Briggs Institute. A comprehensive search was conducted across multiple Chinese and English databases, covering the period from database inception to October 30, 2025. Results: A total of 4 quasi-experimental studies and 19 randomized controlled trials were included. The nursing interventions covered four categories: cold stimulation therapy, salivary substitute products, moisturization, and acupoint stimulation therapy, with intervention frequency varying depending on the study objectives. Assessment tools included subjective measures such as the Visual Analogue Scale and the Numerical Rating Scale, as well as objective measures including resting salivary flow rate and pH value. The patients' thirst levels showed significant improvement after the interventions. Conclusion: Thirst management interventions for ICU patients are diverse, but the overall effectiveness needs further clinical validation. A comprehensive, standardized, and multidimensional intervention plan should be developed and tailored to individual patient needs.
