No results posted yet for this study

Summary

Glottis mask airway (GMA) is supraglottic airway device and is frequently used in patients undergoing general anesthesia. However, gastroesophageal reflux remains a risk during ventilation through supraglottic airway devices. The classical shaped GMA and tulip shaped GMA differ in the shape of their tips. And theoretically the tulip shaped tip fits the larynx better. This study aims to compare the incidence of gastroesophageal reflux during ventilation through classical shaped vs tulip shaped glottis mask airway.
