Comparison of gastric insufflation between Baska mask LMA and Proseal LMA using abdominal ultrasound- a double blinded randomized controlled trial

This is a double blinded randomized controlled study evaluating the gastric isufflation between baska mask and proseal Ima using abdominal ultrasound in early days. SAD is used only for elective procedures. but on the following years it is used in difficult intubation. Proseal LMA is a second generation reusable supraglottic airway device with an airway lumen and a drain tube.The drain tube helps in decompression of stomach and drainage of regurgitant material. BASKA MASK is the latest addition to the supraglottic airway devices,with a cuffless dynamic self inflating membranous bowl and a dual drainage tube system for effective drainage of gastric contents providing option for continuous suctioning of gastric contents. by this study we can compare the gastric insufflation in both Baska Mask LMA and LMA Proseal and to identify which among the two prevent gastric aspiration effectively.
