ABSTRACT
Objective To evaluate the clinical effects of multiple rewarming interventions in adult hypothermia trauma patients.Methods A systematic search of Cochrane Library,PubMed,EMBASE,Scopus,CINAHL,Chinese Biomedical Literature Database (CBM),Chinese Knowledge Infrastructure (CNKI),VIP and Wan Fang Database was carried out to identify all randomized controlled trials(RCTs) and controlled clinical trials(CCTs) that explored the effects of rewarming interventions in adult hypothermia trauma patients.The quality of the literature was evaluated using JBI 2008 RCT and quasi-experimental study evaluation criteria.Data and network plot were analyzed and drawn by ADDIS 1.16.7 software.Results Totally 6 RCTs and 1 quasi-experimental design were included,involving 10 interventions and 619 patients.There was statistically significant difference in body temperature after rewarming between the warm blankets and the forced-air blankets in all rewarming measures.The results of the top three interventions were carbon-fiber heating blanket(set to 42℃),forced-air blankets,warmed intravenous fluids plus blanket which resulted from the primary outcome indicators.The incidence of chills and cold discomfort decreased with the use of forced-air blankets and chemical heat pad as compared with traditional warm blankets,while the heart rate of the patients who used chemical heating pads and continuous heating of carbon fiber blanket were declined more than those used normal blankets.Conclusion The effects of carbon-fiber heating blanket which set to 42°C was the best method in all rewarming interventions.But this conclusion still requires randomized controlled trials with larger sample size to further verify.
