METHODS: A literature search was performed in MEDLINE (via Pubmed), Scopus, Web of Science, and Google Scholar databases from September to November 2022. Keywords combined with the Boolean operators (AND/OR) were used in both free text and Medical Subject Headings. Studies on adult patients published between 01/01/2016 and 28/09/2022 were searched, with no geographical restrictions.
RESULTS: At the end of the selection process, 14 studies were included that investigated capnography in out-of-hospital CPR and reported at least 1 outcome between end-tidal carbon dioxide and ROSC or survival.
CONCLUSIONS: Capnography is an advantageous tool due to its noninvasive characteristics, ease of use, and immediacy of data. In out-of-hospital cardiac arrest, the use of the end-tidal carbon dioxide appears to be an appropriate complementary tool to support clinical decisions, such as correct positioning of the endotracheal tube, optimizing ventilation in CPR, and as a predictor of ROSC.
方法:在MEDLINE(通过Pubmed)中进行了文献检索,Scopus,WebofScience,以及2022年9月至11月的GoogleScholar数据库。在自由文本和医学主题词中都使用了与布尔运算符(AND/OR)结合的关键词。搜索2016年1月1日至2022年9月28日之间发表的成人患者研究,没有地域限制。
结果:在选择过程结束时,包括14项研究,这些研究调查了院外CPR中的二氧化碳图,并报告了潮气末二氧化碳与ROSC或生存率之间的至少1个结果。
结论:由于其无创特性,二氧化碳描记术是一种有利的工具,易用性,数据的即时性。院外心脏骤停,使用潮气末二氧化碳似乎是支持临床决策的适当补充工具,如气管内导管的正确定位,优化心肺复苏术中的通气,并作为ROSC的预测因子。
