We aimed to study the relationship between gastric cross\u2010sectional area, assessed by ultrasound, and volumes of clear fluids ingested by pregnant women. We recruited 60 non\u2010labouring third\u2010trimester pregnant women in a randomised controlled and assessor\u2010blinded study. A standardised scanning protocol of the gastric antrum was performed in the 45\u00b0 semirecumbent and 45\u00b0 semirecumbent\u2010right lateral positions. Subjects were randomly allocated to drink one out of six predetermined volumes of apple juice (0 ml, 50 ml, 100 ml, 200 ml, 300 ml, 400 ml). Qualitative and quantitative assessments at a baseline period after an 8\u2010h fast, and immediately after the drink, were used to establish the correlation between antral cross\u2010sectional area and volume ingested. A predictive model to estimate gastric volume was developed. Antral cross\u2010sectional area in the semirecumbent right lateral position significantly correlated with the ingested volume (Spearman rank correlation = 0.7; p &lt; 0.0001). A cut\u2010off value of 9.6 cm\n                    <jats:sup>2<\/jats:sup>\n                    discriminated ingested volumes \u2265 1.5 ml.kg\n                    <jats:sup>\u22121<\/jats:sup>\n                    with a sensitivity of 80%, a specificity of 66.7%, and an area under the curve of 0.82. A linear predictive model was developed for gastric volume based only on antral cross\u2010sectional area (Volume (ml) = \u2212327.1 + 215.2 \u00d7 log (cross\u2010sectional area) (cm\n                    <jats:sup>2<\/jats:sup>\n                    )). We conclude that in pregnant women in the third trimester of gestation, the antral cross\u2010sectional area correlates well with volumes ingested, and this cut\u2010off value in the semirecumbent right lateral position discriminates high gastric volumes.\n                  <\/jats:p>","DOI":"10.1111\/anae.14131","type":"journal-article","created":{"date-parts":[[2017,12,19]],"date-time":"2017-12-19T04:46:43Z","timestamp":1513658803000},"page":"295-303","source":"Crossref","is-referenced-by-count":78,"title":["Gastric ultrasound in the third trimester of pregnancy: a randomised controlled trial to develop a predictive model of volume assessment"],"prefix":"10.1111","volume":"73","author":[{"given":"C.","family":"Arzola","sequence":"first","affiliation":[{"name":"Department of Anesthesia, Department of Obstetrics and Gynecology University of Toronto and Mount Sinai Hospital Toronto Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Perlas","sequence":"additional","affiliation":[{"name":"Department of Anesthesia University of Toronto and Toronto Western Hospital\u2010UHN Toronto Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.
