Using a\u00a0life-like manikin suitable for a\u00a0pulmonary aspiration model, we aimed to assess the relationship between regurgitated and aspirated clear fluid volumes, and to determine the minimal value of the volume of liquid regurgitated that may lead to pulmonary aspiration of fluid volume \u2265 0.8 mL kg-1 (around 60 mL) that is likely to cause lung injury.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Several volumes of water ranging from 30 to 150 mL were injected in a\u00a0randomized order, at a\u00a0flow rate of 20 mL per second, into the esophagus of a\u00a0manikin lying in the supine position on a\u00a0non-tilted table, with the manikin head in the extension or in the sniffing position. Aspirated volumes were measured in the manikin bronchi, by an investigator blinded to the volume injected. Aspiration was defined as positive when the volume of collected water was \u2265 60 mL for at least one of the five injections of each volume of water.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The minimal volume of water injected into the esophagus for an aspirated volume \u2265 0.8 mL kg-1 was 85 mL in the sniffing position, and was 150 mL in the extension position.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>These results suggest that the critical cut-off value of gastric fluid volume to be considered for the risk of significant pulmonary aspiration would be \u2265 85 mL (\u2265 1 mL kg-1), in the sniffing position.
