[Evidence summary for postoperative hypothermia rewarming in adults with severe burns]

Objective: To retrieve, evaluate, and summarize the best evidence for postoperative hypothermia rewarming in adults with severe burns. Methods: Foreign language databases including Cochrane Library, Joanna Briggs Institute Evidence-Based Health Care Center Database, PubMed, Ovid-Medline, BMJ Best Practice, and Web of Science were retrieved with the search terms of " severe burn/major burn/severe degree burn" , " hypothermia/warming intervention/hypothermia/temperature/body temperature change" , and " postoperative /perioperative/peri-operative/post-operative" and Chinese databases including Chinese Journal Full-Text Database, Wanfang Database, and VIP Database were retrieved with the search terms of "//" , "/" , and "" to obtain all the publicly published evidence for postoperative hypothermia rewarming in adults with severe burns from the establishment of each database to April 2018, including systematic evaluations, guidelines, expert consensus, evidence summary, and original research closely related to the evidence. The literatures were screened and evaluated for their quality, the evidences were extracted from them, evaluated, classified in order to summarize the best evidences. Results: A total of 8 literatures were included, including one systematic evaluation, three guidelines, one expert consensus, and three evidence summaries. Finally, the best evidences in 8 aspects including the body temperature monitoring site, body temperature monitoring frequency, surface heating, in vivo heating, rewarming start, multi-strategy rewarming, equipment, and personnel training were summarized. Conclusions: Based in the evidence-based nursing method, this study retrieves and evaluates the literature, summarizes the evidence analysis and evaluation, and obtains the best evidences of postoperative hypothermia rewarming in adult patients with severe burns, which provides a strong reference for the clinical implementation of rewarming.
