Introduction. The most severe complication of using supraglottic airway devices for airway management is pulmonary aspiration, and it’s related with poor outcomes. The aim of the study is to compare the ability of different types of supraglottic airways devices to protect the airways from aspiration during simulated regurgitation in fresh cadavers. Material and methods 34 fresh cadavers was randomized in 2 groups. In the 1-st group «laryngeal tube» and in the 2-nd group «laryngeal mask» supraglottic airway devices were used. After that gastric tube was inserted, and the bolus of colored solution was infused into the stomach. Regurgitation was achieved by compressing the epigastric region. The endoscopic evaluation of supraglottic airway device positioning was made and the fact of exposure of colored solution into the airways. Results There wasn’t statistic difference in the frequency of pulmonary aspiration between groups. There wasn’t any event of hit of colored solution to the oral cavity from the esophagus in the both groups. There wasn’t statistic difference in the frequency of pulmonary aspiration from the oral cavity. Conclusion In this study there wasn’t statistic differences between the «laryngeal mask» and «laryngeal tube» groups in the frequency of event of endoscopic visualization of colored solution in the airways after the infusion the solution in the stomach and in the frequency of endoscopic visualization of colored solution in the airways after infusion the solution in the oral cavity.
