When and how? date: 2022-03-01 journal: Clin Nutr ESPEN DOI: 10.1016/j.clnesp.2022.02.120 sha: 5ba40739a271404838a123a74e530da151097917 doc_id: 935522 cord_uid: rkyk6v2a nan Oscar Iván Quintero O, FT, MgInn 1 ; Maria Paula Garcia-Garcia, MD 1 We agree that consensus concerning these patients' nutritional support is lacking. PN seems to be the nutritional choice in NIV patients for some authors, as Subramanian et. al, most likely explained by the fear of complications associated with the presence of nasogastric tubes while using a conventional oronasal mask (1) . Despite this, post-pyloric feeding tubes are often used to favor early nutrition, ameliorate enteral nutrition tolerance, and diminish the risk of aspiration pneumonia (2). However, we would like to highlight some aspects that must be carefully reviewed. First, the authors fail to describe the type of respiratory insufficiency leading to NIV, and the criteria used to determine nutritional management, basing their choice merely on subjectivity which represents a great bias in this paper. Remarks were made on how recently PN is recommended when enteral nutrition When evaluating nutrition management in any patient requiring NIV, EN should be considered a feasible and safe option with the aid of novel devices designed for such purpose. However, further clinical randomized trials are needed in order to explore the best nutritional approach in NIV.
