Brief Summary
Airway management is one of the basic topics in anesthetic practice. Use of endotracheal intubation and face mask are standard methods to maintain an open airway widely adopted for many years. As a result of a search for more appropriate choices from the point of view of effectiveness, reliability and side effects, supraglottic airway devices (SGAD) have been developed. SGAD's are used for thyroid surgery, ear surgery, carotid endarterectomy, adenotonsillectomy and laser pharyngoplasty, which require a variety of head-neck positions. Changing the head and neck position leads to changes in the shape of the pharynx, which causes variation in the cuff pressure and oropharyngeal leak pressure. Oropharyngeal leak pressure values play a determining role in protecting the airway from high cuff pressure. Additionally it shows that the laryngeal mask is correctly placed and is a sign of the effectiveness of positive pressure ventilation. During surgery head-neck and trunk position may change. As a result there is a need for research evaluating the effect of head and neck position on oropharyngeal leak pressure during SGAD use. AIM The aim of this study is to compare the effect of different head and neck positions on the oropharyngeal leak pressure in LMA-Unique and I-Gel applications. Additionally the placement duration, ease and success of these two supraglottic airway devices will be compared.

Study Arms (2)
Group U (UNIQUE)
ACTIVE COMPARATORGroup LMA- UNIQUE, inserted according to described standard method. Between 30-40 kg, no.3. Between 50-70 kg, no. 4 Between 70-100 kg, no. 5. LMA-Unique Before SGAD is inserted, a water-based lubricant without local anesthetic, was spread on the surfaces that will touch the palate and LMA-U cuff was completely deflated.oup U (UNIQUE): Group Laryngeal Mask Airway-Unique.
Group I (I-GEL ): Group I-GEL
EXPERIMENTALGroup I (I-GEL): Between 30-60 kg, no. 3. Between 50-90 kg, no. 4. For \> 90 kg no.5. I-GEL
Interventions
Before LMA-Unique was inserted, to lubricate the surface in contact with the palate a water-based gel without local anesthetic was applied to completely cover the LMA-Unique cuff.
Before I-gel was inserted, to lubricate the surface in contact with the palate a water-based gel without local anesthetic was applied to completely cover the I-GEL cuff. I-GEL: K-Y Jelly® is a registered trademark of Johnson and Johnson Inc
