However, gastric ultrasonography can safely assess gastric content and prevent bronchoaspiration. Therefore, a systematic review was performed in order to verify the efficacy of ultrasonography in the qualitative and quantitative analyses of gastric content.  METHODS: A literature review of articles published between 2009 and 2019 in the PubMed and LILACS databases was conducted using combinations of the keywords \u201cgastric ultrasound,\u201d \u201cgastric emptying,\u201d and \u201cgastric content.\u201d  RESULTS: Of the 20 articles found, 19 chose the antral region as the best site for qualitative analysis of the gastric content. Regarding quantitative measurement, the most commonly used method to calculate the gastric volume in eight articles was the formula \u201cGastric Volume = 27 + (14.6 \u00d7 ATAG) \u2212 (1.28 \u00d7 Age),\u201d in which the area of the transverse section of the gastric antrum (ATAG) could also be calculated by the largest antral diameters or by free tracing.  CONCLUSION: An efficient evaluation of the gastric content can be performed by ultrasonography of the antral region, contributing to greater safety in the clinical management of patients with increased risk for bronchoaspiration during airway management.<\/jats:p>","DOI":"10.1590\/1806-9282.66.12.1725","type":"journal-article","created":{"date-parts":[[2020,12,17]],"date-time":"2020-12-17T18:21:52Z","timestamp":1608229312000},"page":"1725-1730","source":"Crossref","is-referenced-by-count":9,"title":["Ultrasonographic evaluation of gastric content and volume: a systematic review"],"prefix":"10.1590","volume":"66","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3361-4626","authenticated-orcid":false,"given":"C\u00e9sar Antonio Tavares da","family":"Rocha","sequence":"first","affiliation":[{"name":"Hospital do Servidor P\u00fablico Estadual de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3035-5569","authenticated-orcid":false,"given":"Lia Mayumi Kubota","family":"Kamada","sequence":"additional","affiliation":[{"name":"Hospital do Servidor P\u00fablico Estadual de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0572-971X","authenticated-orcid":false,"given":"Pedro Hilton de","family":"Andrade Filho","sequence":"additional","affiliation":[{"name":"Hospital do Servidor P\u00fablico Estadual de S\u00e3o Paulo,  Brasil; FMUSP,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5945-3827","authenticated-orcid":false,"given":"Isabela Araujo","family":"Villaverde","sequence":"additional","affiliation":[{"name":"Universidade Cidade de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4252-7113","authenticated-orcid":false,"given":"Jacqueline Yamahata Barbosa","family":"Shiro","sequence":"additional","affiliation":[{"name":"Universidade Cidade de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1494-0784","authenticated-orcid":false,"given":"Jo\u00e3o Manoel da","family":"Silva Junior","sequence":"additional","affiliation":[{"name":"Hospital do Servidor P\u00fablico Estadual de S\u00e3o Paulo,  Brasil; FMUSP,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2020,12]]},"reference":[{"issue":"1","key":"ref1","doi-asserted-by":"crossref","first-page":"89","DOI":"10.1213\/ANE.0000000000003372","article-title":"Diagnostic accuracy of point-of-care gastric ultrasound","volume":"128","author":"Kruisselbrink R","year":"2019","journal-title":"Anesth Analg"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1016\/j.ijsu.2016.01.043","article-title":"Risk factors for fatal outcome in surgical patients with postoperative aspiration pneumonia","volume":"27","author":"Studer P","year":"2016","journal-title":"Int J Surg"},{"issue":"1","key":"ref3","doi-asserted-by":"crossref","first-page":"49","DOI":"10.1001\/archsurg.1973.01350130051011","article-title":"Aspiration pneumonia: clinical outcome following documented aspiration","volume":"106","author":"Cameron JL","year":"1973","journal-title":"Arch Surg"},{"issue":"7","key":"ref4","doi-asserted-by":"crossref","first-page":"1930","DOI":"10.1097\/01.CCM.0000069738.73602.5F","article-title":"Epidemiology and impact of aspiration pneumonia in patients undergoing surgery in Maryland, 1999\u20132000","volume":"31","author":"Kozlow JH","year":"2003","journal-title":"Crit Care Med"},{"issue":"1","key":"ref5","doi-asserted-by":"crossref","first-page":"E27","DOI":"10.1055\/a-0783-2170","article-title":"Gastric emptying of low- and high-caloric liquid meals measured using ultrasonography in healthy volunteers","volume":"5","author":"Mazzawi T","year":"2019","journal-title":"Ultrasound Int Open"},{"issue":"1","key":"ref6","doi-asserted-by":"crossref","first-page":"82","DOI":"10.1097\/ALN.0b013e3181a97250","article-title":"Ultrasound assessment of gastric content and volume","volume":"111","author":"Perlas A","year":"2009","journal-title":"Anesthesiology"},{"issue":"12","key":"ref7","doi-asserted-by":"crossref","first-page":"1015","DOI":"10.1097\/EJA.0b013e32833161fd","article-title":"Could a single standardized ultrasonographic measurement of antral area be of interest for assessing gastric contents?
