However, adverse events associated with this device can occur. The Food and Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database was explored for patient\u2010related adverse events associated with Ambu\u00ae aScope\u2122 use between January 1, 2000 and December 15, 2023. Search terms included \u201cAmbu\u201d and \u201cAscope.\u201d Thirty unique adverse events were identified. Twenty\u2010one of the events were associated with patient injury, and 9 with device malfunction. Eight patient\u2010reported problems were documented as foreign bodies, 3 events as airway obstruction, desaturation, or hypoxic events, and 1 event as anxiety\/cardiac arrest. The remaining 18 reported insufficient information other than associated with patient injury. We found that Ambu\u00ae aScope\u2122 flexible nasolaryngoscopes and bronchoscopes are a common and effective tool for airway evaluations that may infrequently serve as a rare form of foreign body with potentially life\u2010threatening consequences.<\/jats:p>","DOI":"10.1002\/ohn.898","type":"journal-article","created":{"date-parts":[[2024,7,11]],"date-time":"2024-07-11T04:04:36Z","timestamp":1720670676000},"page":"1928-1930","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Complications Associated with AMBU\u2122 Scope Use: An FDA MAUDE Analysis"],"prefix":"10.1002","volume":"171","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7422-4280","authenticated-orcid":false,"given":"David R.","family":"Grimm","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Stanford University School of Medicine Palo Alto California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akash S.","family":"Halagur","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Stanford University School of Medicine Palo Alto California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noel","family":"Ayoub","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery,\u00a0Division of Rhinology and Skull Base Surgery Mass Eye and Ear Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,7,11]]},"reference":[{"issue":"6","key":"e_1_2_7_2_1","first-page":"2433","article-title":"Development of endotracheal intubation devices for patients with tumors","volume":"12","author":"Liu Y","year":"2022","journal-title":"Am J Cancer Res"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2044.2010.06406.x"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/08850666221148645"},{"key":"e_1_2_7_5_1","unstructured":"Manufacturer and User Facility Device Experience (MAUDE) Accessed January 22 \u00a02024.https:\/\/www.accessdata.fda.gov\/scripts\/cdrh\/cfdocs\/cfmaude\/search.cfm"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1183\/09059180.00005710"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2023.162976"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/anae.14891"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1128\/CMR.00085-12"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.otc.2018.08.014"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12890-022-01982-4"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/aas.12094"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12871-022-01618-4"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.4103\/2229-5151.164995"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12887-024-04705-2"},{"key":"e_1_2_7_16_1","unstructured":"Health Economics.
