The most used airway management strategies are different types of supraglottic airway devices (SAD) for transurethral resection of bladder and ureteroscopy in urological surgery . Classical laryngeal mask airway (LMA-C) and I-Gel SADs are being used already. The aim of this study was to evaluate and compare the performance of a new type of SAD the Baska Mask® with I-gel and LMA-C regarding their insertion times, durations, perioperative complications and effects on hemodynamic parameters, peak airway pressures (Paw) and airway plato pressures in urological surgery as well.

The main suggestion about the Baska Mask® is that it's the most appropriate airway device with high Paws. In high Paws, higher air leaks may occur from the sides of cuff and this causes hypoventilation. So the main aim of this study is to evaltuate three devices in terms of insertion and ventilation times, the "first attempt" success rates, the additional maneuvering requirements and complications developed after intervention.
The secondary objective of the study was to evaluate all three SADs in terms of airway pressures producing sufficient tidal volume and hemodynamical parameters.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Classical LMA | Experimental | Classical LMA insertion: LMA-C insertion was done in supine position and with a standard gel pillow with the patient's head on following anesthesia induction. The insertion was verified with the manual ventilation of the patient and end-tidal carbon dioxide pressure waveform. |
|
| I-gel | Experimental | I-gel LMA insertion: The I-gel LMA insertion was done in supine position and with a standard gel pillow with the patient's head on following anesthesia induction. The insertion was verified with the manual ventilation of the patient and end-tidal carbon dioxide pressure waveform. |
|
| The Baska Mask® | Experimental | The Baska Mask® insertion: The Baska Mask® insertion was done in supine position and with a standard gel pillow with the patient's head on following anesthesia induction. The insertion was verified with the manual ventilation of the patient and end-tidal carbon dioxide pressure waveform. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| LMA-C | Device | LMA-C will be placed into the patients airway following anesthesia induction. The placement will be done as suggested in supine position with a standard gel pillow under patients head. |
| Measure | Description | Time Frame |
|---|---|---|
| Insertion times | It was evaluated that how many secs does it take to insert properly. | Perioperative |
| Ventilation times | It was evaluated that how many secs does it take to ventilate the patient. | Perioperative |
| First attemp success rates | In how many patients it was inserted at first attempt | Perioperative |
| The additional maneuvering | ıt was evaluated how many maneuvers needed to insert the device. | Perioperative |
| Airway related complications | Complications like Bloodstain of the mask, Dysphagia, Tongue injury, Lips injury, Teeth injury, Palate injury, Sore throat, Hoarseness, Desaturation , Laryngospasm, Regurgitation/aspiration were evaluated. | Perioperative |
| Measure | Description | Time Frame |
|---|---|---|
| Airway PAP and Plateau pressures | Both pressures were evaluated following device insertion and then in every 10 mins. | Perioperative |
| Haemodynamic parameters, heart rate bpm, systolic and diastolic arterial pressures mmHg |
