目的系统评价围手术期保温措施对预防手术部位感染的作用,为预防与控制手术部位感染提供循证依据。方法计算机检索Pubmed、Cochrane Library、EMBASE、中国期刊全文数据库、万方-医药期刊全文数据库、重庆维普全文数据库、中国生物医学文献数据库,并辅以手工检索、文献追溯等方法,收集围手术期采用保温措施的临床随机对照研究,筛选、评价文献质量并提取有效数据进行荟萃分析。结果筛选出符合纳入标准的随机对照试验9项,共2 916例患者,患者发生手术部位感染率保温组为4.3%,对照组为11.4%;荟萃分析结果表明,在围手术期采取适当的保温措施可以降低手术部位感染的发生率(OR=0.34,95%CI:0.25~0.47,P<0.001)。结论围手术期采取适当的保温措施,对预防患者手术部位感染是有效的,建议围手术期采用适当的保温措施,预防轻度低体温的发生,以减少手术部位的感染。
Objective To systematically evaluate the effect of perioperative insulation measures on the prevention of surgical site infections and provide evidence base for the prevention and control of surgical site infections. Methods Pubmed, Cochrane Library, EMBASE, Chinese Journal Full-text Database, Wanfang - Medicine Journal Full-text Database, Chongqing VIP database and Chinese Biomedical Literature Database were searched by computer. The methods of manual retrieval and literature retrospective were collected. Insulation measures clinical randomized controlled study, screening, evaluation of literature quality and extract valid data for meta-analysis. Results A total of 916 randomized controlled trials were selected. A total of 2 916 patients were included in this study. The infection rate of the surgical site was 4.3% in the heat-preservation group and 11.4% in the control group. The meta-analysis showed that during the perioperative period, proper insulation Measures can reduce the incidence of surgical site infection (OR = 0.34, 95% CI: 0.25 to 0.47, P <0.001). Conclusion Perioperative proper insulation measures are effective in preventing surgical site infections. It is suggested that appropriate measures of perinatal insulation should be taken to prevent mild hypothermia and reduce the infection in the surgical site.
