Comparison of Endotracheal Intubation Over the Aintree With Fiberoptic Bronchoskop Via the I-gel and LMA Protector

Investigators aimed to compare the ease of use of the LMA protector and I-gel LMA for tracheal intubation with the Aintree catheter in our study. Laryngeal mask airway (LMA) protector is the second generation perilaryngeal seal type supraglottic airway tool. The I-gel LMA is the second generation uncuffed supraglottic airway device. The Aintree Intubation Catheter has been designed for assisted fiberoptic intubation and for uncomplicated, atraumatic endotracheal tube exchange.Both LMA types have a structure that permits endotracheal intubation. In cases of difficult intubation, these two LMA types can be used. In the literature, there is no study comparing these two LMA types using Aintree catheter.Difficult Airway Society (DAS) published a guide for tracheal intubation in 2011 using Aintree. According to this guide, LMA type LMA Supreme is the most unfavorable for this process. However, there is no research or recommendation on the type of LMA most suitable for use in the literature. In accordance with the data of this study, it will be tried to show which LMA type may be suitable for intubation with Aintree catheter in patients.
