Clinical Trial Summary

LMA insertion provide an intact airway for many surgeries during general anesthesia . LMA insertion technique was defined when it was first produced by Archie Brain . Accordingly, it is recommended to advance the device to the level where resistance is felt blindly. However, placing LMA may not always be smooth and uncomplicated. Thus, gas leaks may occur and intragastric pressure increase may occur due to gastric insufflation. To overcome these difficulties, the placement of the LMA under direct vision using a laryngoscope has been described in several studies . Previous studies have shown that the reliability of the laryngeal mask can be demonstrated by the oropharyngeal cuff leak test . In addition, the classification of the image of the laryngeal structures mediated by fiberoptic imaging and vocal cords from the LMA gives us information about the availability of effective positive pressure ventilation.

In addition, the classification of the image of the laryngeal structures mediated by fiberoptic imaging and vocal cords from the LMA gives us information about the availability of effective positive pressure ventilation.In cases where difficulties are found in laryngeal mask placement, using direct laryngoscope or videosingoscope, placement is frequently applied in anesthesia practice. Kim GW et al investigated LMA placement with direct laryngoscope. However, there is no study investigating the effectiveness of videongoscopes. Videoingoscopes have wide viewing angles through their cameras located at the blade tips. For this reason, we think that it will be advantageous in placing a laryngeal mask.
