ObjectivesTo assess the effectiveness of cold therapy for pain and anxiety associated with chest tube removal.DesignA Systematic review and meta-analysis of randomized controlled trials.Data SourcesArticles were searched from Cochrane Library, PubMed, Embase, CINAHL, ProQuest, Airiti Library, China National Knowledge Infrastructure, and the National Digital Library of Theses and Dissertations in Taiwan.Review/Analysis MethodsEight electronic databases were searched from inception to August 20, 2022. The Cochrane Risk of Bias 2.0 tool was used to assess the quality of the included studies. Using a random-effects model, we calculated Hedges' g and its associated confidence interval to evaluate the effects of cold therapy. Cochrane's Q test and an I2 test were used to detect heterogeneity, and moderator and meta-regression analyses were conducted to explore possible sources of heterogeneity. Publication bias was assessed using a funnel plot, Egger's test, and trim-and-fill analysis.ResultsWe examined 24 trials involving 1,821 patients. Cold therapy significantly reduced pain during and after chest tube removal as well as anxiety after chest tube removal (Hedges' g: -1.28, -1.27, and -1.80, respectively). Additionally, the effect size of cold therapy for reducing anxiety after chest tube removal was significantly and positively associated with that of cold therapy for reducing pain after chest tube removal.ConclusionsCold therapy can reduce pain and anxiety associated with chest tube removal.Copyright © 2023 American Society for Pain Management Nursing.
