Although the insertion of a nasogastric tube is a simple procedure, it can be associated with complications that lead to potentially serious consequences. The knotting of a nasogastric tube around an endotracheal tube is rare. Here, we report a case in which the nasogastric tube became knotted around the nasal endotracheal tube in the nasopharynx. We compare this case with 4 previous similar cases and provide a theory of how the nasogastric tube might have become knotted.<\/jats:p>","DOI":"10.2344\/anpr-67-04-01","type":"journal-article","created":{"date-parts":[[2021,6,29]],"date-time":"2021-06-29T18:14:58Z","timestamp":1624990498000},"page":"90-93","source":"Crossref","is-referenced-by-count":1,"title":["Nasogastric Tube Knotted Around a Nasal Endotracheal Tube in the Nasopharynx: Possible Cause"],"prefix":"10.2344","volume":"68","author":[{"given":"Yunosuke","family":"Okada","sequence":"first","affiliation":[{"name":"Division of Pediatric Dentistry, School of Dentistry, Health Sciences University of Hokkaido, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanako","family":"Ohke","sequence":"additional","affiliation":[{"name":"Division of Dental Anesthesiology, School of Dentistry, Health Sciences University of Hokkaido, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroyo","family":"Yoshimoto","sequence":"additional","affiliation":[{"name":"Division of Dental Anesthesiology, School of Dentistry, Health Sciences University of Hokkaido, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Misato","family":"Kobashi","sequence":"additional","affiliation":[{"name":"Division of Pediatric Dentistry, School of Dentistry, Health Sciences University of Hokkaido, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masato","family":"Saitoh","sequence":"additional","affiliation":[{"name":"Division of Pediatric Dentistry, School of Dentistry, Health Sciences University of Hokkaido, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Makoto","family":"Terumitsu","sequence":"additional","affiliation":[{"name":"Division of Dental Anesthesiology, School of Dentistry, Health Sciences University of Hokkaido, Hokkaido, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1191","published-online":{"date-parts":[[2021,6,29]]},"reference":[{"key":"2021062918143797700_i0003-3006-68-2-90-b01","doi-asserted-by":"crossref","unstructured":"Sanaie\n              S,\n            \n            \n              Mahmoodpoor\n              A,\n            \n            \n              Najafi\n              M.\n            \n          \n          Nasogastric tube insertion in anaesthetized patients: a comprehensive review.\n\t\t\t\t\tAnaesthesiol Intensive Ther.\n\t\t\t\t\t2017;\n\t\t\t\t\t49:\n\t\t\t\t\t57\u2013\n\t\t\t\t\t65.","DOI":"10.5603\/AIT.a2017.0001"},{"key":"2021062918143797700_i0003-3006-68-2-90-b02","doi-asserted-by":"crossref","unstructured":"Cappell\n              MS,\n            \n            \n              Scarpa\n              PJ,\n            \n            \n              Nadler\n              S,\n            \n            \n              Miller\n              SH.\n            \n          \n          Complications of nasoenteral tubes.
