Clinical Trial 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	laryngeal mask correct insertion and than fixation	The placement and fixation of the laryngeal mask will be evaluated by measuring the end-tidal carbon dioxide value with the aid of a capnogram, the formation of appropriate chest extension, and the absence of audible leakage at 20 cm H2O peak inspiratory pressure.	intraoperative period (From the insertion of the laryngeal mask airway to its removal at the end of the procedure)
Secondary	Evaluation of successful laryngeal mask placement with a fiberoptic bronchoscope (FOB)	To evaluate the best fiberoptic bronchoscopic view while insertion of proseal laryngeal mask	intraoperative period (From the insertion of the laryngeal mask airway to its removal at the end of the procedure)
