The aim of this systematic review (SR) is to summarize available clinical evidence related to safety and efficacy of continuous EN (C\u2010EN) or intermittent EN (I\u2010EN) in patients in the ICU, in relation to appropriated supply on nutrition status, gastrointestinal symptoms or tolerance, and risks on respiratory tract infections. A literature search of PubMed, EMBASE, and Google Scholar was performed comparing C\u2010EN vs I\u2010EN, and 4196 published studies were screened. Nineteen studies were selected for this SR reporting types of ICU, nutrition protocols, and study period. Effects of C\u2010EN vs I\u2010EN were presented according to the impact on nutrition status, digestive tract, and respiratory tract. The contrasting results confirmed that the optimal delivering mode of EN remains controversial. Future studies dedicated to identifying the benefits and limitations of C\u2010EN or I\u2010EN should be realized.<\/jats:p>","DOI":"10.1002\/jpen.2316","type":"journal-article","created":{"date-parts":[[2022,1,4]],"date-time":"2022-01-04T07:38:45Z","timestamp":1641281925000},"page":"486-498","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Safety
