LMA Fixation Method
Condition: Fixation Device; Complications
Study type: Interventional

Summary: 
      Proseal laryngeal mask airway (LMA) is frequently used for safe airway management in modern
      anesthesia. Improper fixation of the LMA may result in subsequent displacement despite
      initial correct placement. In this study, researchers aimed to present the detection method
      researchers developed for PLMA, which is different from the classical methods.

      PLMA will place with a new fixation method in adult patients in the lithotomy position who
      will undergo uretero-renoscopic lithotripsy. The fixation will prepare by sewing a button on
      one end of the adjustable elastic. Successful insertion will assess clinically (capnogram,
      appropriate chest excursion, and the absence of an audible leak at a peak inspiratory
      pressure of 20 cm H2O) and with a fiberoptic bronchoscope (FOB) (grade and distance visible
      to vocal cords). At the end of the operation, it will be examined whether there is any
      displacement.

      SPSS 21.0 (Version 22.0, SPSS, Inc, Chicago, IL, USA) program will be used for statistical
      analysis. After applying the Shapiro-Wilk test for normality, the student's t test will be
      used if the distribution is normal, and the Mann-Whitey U test will be used if the
      distribution is not normal. Fisher's exact test or chi-square test will be used for
      categorical variables. Results p<0.05 will be considered significant.
