This study aimed to assess differences in quantitative (Perlas score) and qualitative (antral cross\u2010sectional area) ultrasound assessments of the gastric antrum performed immediately before and after caesarean section. Forty\u2010three women having elective caesarean section performed under spinal anaesthesia were studied in the semirecumbent and semirecumbent\u2010right lateral positions. Thirty\u2010nine women showed no change in stomach contents using the Perlas score between the two measurement periods; four women showed a change, but by one grade only. The median (\n                    <jats:styled-content style=\"fixed-case\">IQR<\/jats:styled-content>\n                    [range]) antral cross\u2010sectional area was 323 (243\u2013495 [103\u2013908]) mm\n                    <jats:sup>2<\/jats:sup>\n                    before, and 237 (165\u2013377 [112\u2013762]) mm\n                    <jats:sup>2<\/jats:sup>\n                    after, caesarean section in the semirecumbent position (p = 0.001); the comparable values in the semirecumbent\u2010right lateral position were 418 (310\u2013640 [161\u20131238]) mm\n                    <jats:sup>2<\/jats:sup>\n                    and 362 (280\u2013491 [137\u20131231]) mm\n                    <jats:sup>2<\/jats:sup>\n                    (p = 0.09). The distance between the skin and the antrum, and the aorta and the antrum, decreased significantly in both positions after surgery. We suggest that our results indicate that stomach contents remain largely unchanged in women having elective caesarean section, but antral cross\u2010sectional area decreases, especially in the semirecumbent position, related to a change in the position of the stomach within the abdomen. This implies that the relationship of antral cross\u2010sectional area to volume of stomach contents, which has been determined for non\u2010pregnant subjects, may not apply in term pregnant women.\n                  <\/jats:p>","DOI":"10.1111\/anae.13605","type":"journal-article","created":{"date-parts":[[2016,8,26]],"date-time":"2016-08-26T07:43:08Z","timestamp":1472197388000},"page":"1284-1290","source":"Crossref","is-referenced-by-count":41,"title":["Changes in qualitative and quantitative ultrasound assessment of the gastric antrum before and after elective caesarean section in term pregnant women: a prospective cohort study"],"prefix":"10.1111","volume":"71","author":[{"given":"C.","family":"Rouget","sequence":"first","affiliation":[{"name":"Department of Anaesthesia and Intensive Care Hospices Civils de Lyon Femme M\u00e8re Enfant Hospital Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.","family":"Chassard","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Intensive Care Hospices Civils de Lyon Femme M\u00e8re Enfant Hospital Lyon France"},{"name":"University of Lyon Claude Bernard Lyon 1 University Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Bonnard","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Intensive Care Hospices Civils de Lyon Femme M\u00e8re Enfant Hospital Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Pop","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Intensive Care Hospices Civils de Lyon Femme M\u00e8re Enfant Hospital Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.
