Efficacy of different warming methods for perioperative hypothermia prevention on body temperature and shivering among transurethral resection patients: A systematic review and meta-analysis study

Abstract

Purpose

The present study attempts to assess the impacts of distinct warming strategies employed to avert perioperative hypothermia on core body temperature and shivering among transurethral resection patients.

Methods

We performed a comprehensive search of Turkish and English keywords across a range of databases, including PUBMED, Web of Science, Cochrane Library, SCOPUS, Ovid, EBSCOhost, Yöktez, DergiPark, and TR Index, to identify studies on the subject published between January 1, 2001–2024. The search procedure yielded 11 studies to be recruited for meta-analysis. We analyzed the data using the trial version of Comprehensive Meta-Analysis Software (CMA). The degree of heterogeneity was quantified using Higgins I² tests, while we assessed publication bias through Kendall's Tau and Egger's regression analyses.

Results

This meta-analysis focuses exclusively on the effects of forced air warming and irrigation fluid warming, as only these methods provided sufficient data to calculate effect size. Our findings demonstrated that while forced air warming significantly affected preoperative (g = 0.279), intraoperative (15th minute, T4) (g = 0.845), postoperative (g = 0.647) body temperature and postoperative shivering (g = −2.279), irrigation fluid warming had a significant impact on postoperative body temperature (g = 1.007) and intraoperative shivering (g = 0.188).

Conclusion

Overall, our results indicated that forced air warming and irrigation fluid warming can serve as a preventive measure against hypothermia and shivering among transurethral resection patients. Given that other forms of warming could not be included in this research, further studies are recommended to explore scholarly evidence on the efficacy of these methods.
