Abstract

Background: Thirst is the most common self-reported symptom in intensive care unit (ICU) patients. There is evidence that oral cooling interventions may alleviate thirst symptoms in ICU patients. However, the evidence needs to be critically evaluated.

Objective: To investigate the effect of oral cooling interventions on alleviating thirst symptoms of ICU patients and explore the effectiveness of different types of oral cooling by subgroup analysis.

Methods: The PubMed, Ovid Embase, the Cochrane Library, Wanfang Data and China National Knowledge Infrastructure databases were searched from inception to 29 October 2023. Randomised controlled trials (RCTs) that reported thirst intensity or thirst distress as outcomes were included. The certainty of the evidence was evaluated by the GRADE approach.

Results: The meta-analysis comprised eight RCTs that included 813 ICU patients. The pooled analysis from eight RCTs showed that oral cooling interventions had significant beneficial effects on thirst intensity (weighted mean difference [WMD] = -2.73, 95% confidence interval [CI] = -3.62 to -1.85, p < 0.01; moderate certainty). The pooled analysis from four RCTs showed that oral cooling interventions could significantly lower the thirst distress scores (standardised mean difference = -0.80, 95% CI = -1.13 to -0.47, p < 0.01; low certainty). Subgroup analysis indicated that cold stimulation (WMD = -3.12) and cold combined with menthol stimulation (WMD = -1.72) could significantly lower the thirst intensity scores.

Conclusion: Oral cooling interventions including cold and menthol had beneficial effects on thirst intensity and thirst distress in ICU patients. The high heterogeneity in methods should be considered when interpreting the results.

Relevance to clinical pratice: This study provides references for the application of oral care strategy in the ICU care field, and encourages nurses to apply the oral cooling plan to improve patients' comfort.

No patient or public contribution: This was a meta-analysis based on data from previous studies.

Trial registration: PROSPERO: CRD42023416059.

口服清凉对缓解ICU患者口渴的有效性：一项meta分析。

背景：口渴是重症监护病房（ICU）患者最常见的自我报告症状。有证据表明，口服降温干预可以缓解重症监护病房患者的口渴症状。然而，需要对证据进行批判性评估。目的：通过亚组分析，探讨口服降温干预对缓解ICU患者口渴症状的效果，并探讨不同类型口服降温干预的效果。方法：检索PubMed、Ovid Embase、Cochrane Library、万方数据和中国国家知识基础设施数据库，检索时间为2023年10月29日。结果包括报告口渴强度或口渴窘迫的随机对照试验（RCTs）。证据的确定性通过GRADE方法进行评估。结果：meta分析纳入8项随机对照试验，共纳入813例ICU患者。8项随机对照试验的汇总分析显示，口服降温干预对口渴强度有显著的有益影响（加权平均差[WMD] = -2.73, 95%可信区间[CI] = -3.62 ~ -1.85, p）。结论：含冷剂和薄荷醇的口服降温干预对ICU患者的口渴强度和口渴痛苦有有益影响。在解释结果时应考虑方法的高度异质性。与临床实践的相关性：本研究为口腔护理策略在ICU护理领域的应用提供参考，鼓励护士应用口腔降温方案，提高患者舒适度。无患者或公众贡献：这是一项基于先前研究数据的荟萃分析。试验注册：PROSPERO: CRD42023416059。

期刊介绍： The Journal of Clinical Nursing (JCN) is an international, peer reviewed, scientific journal that seeks to promote the development and exchange of knowledge that is directly relevant to all spheres of nursing practice. The primary aim is to promote a high standard of clinically related scholarship which advances and supports the practice and discipline of nursing. The Journal also aims to promote the international exchange of ideas and experience that draws from the different cultures in which practice takes place. Further, JCN seeks to enrich insight into clinical need and the implications for nursing intervention and models of service delivery. Emphasis is placed on promoting critical debate on the art and science of nursing practice. JCN is essential reading for anyone involved in nursing practice, whether clinicians, researchers, educators, managers, policy makers, or students. The development of clinical practice and the changing patterns of inter-professional working are also central to JCN''s scope of interest. Contributions are welcomed from other health professionals on issues that have a direct impact on nursing practice. We publish high quality papers from across the methodological spectrum that make an important and novel contribution to the field of clinical nursing (regardless of where care is provided), and which demonstrate clinical application and international relevance.
