Background
In this study, we evaluated and compared the performance of the Baska Mask® (PTY Ltd,Australia), I-Gel®(Intersurgical Ltd,UK) and Classic laryngeal maske airway (cLMA) for use in anesthesia in adult patients undergoing a variety of outpatient urologic interventions.
Methods
One hundred fifty patients with ASA I-III physical status were enrolled  for elective urological interventions without neuromuscular blocking. The patients were divided into Baska Mask, I-Gel, and classic LMA groups, each with 50 patients. We evaluated the "first attempt" success rates, insertion time, ventilation  time, airway dynamics-complications and  hemodynamic variables.
Results
There were no significant differences among three groups regarding demographic data, airway dynamics, complications and  hemodynamic variables. The "first attempt" success rate were 98%, 92%, 88% classic LMA, I-Gel, Baska Mask,respectively.  Insertion and ventilation times were different between groups(p<0,001 for each).Both insertion and ventilation times of classical LMA were found to be shorter than others (insertion times 5.78±1.72sec&ventilation times11.72±4.72sec).The insertion and ventilation times in the I-Gel group were 7.28 ± 2.66 and 15.38 ± 6.7 sec.The longest insertion and ventilation times were in Baska Mask with 12.04 ± 6.25 and 21.26 ± 8.53 sec.When considering the additional maneuvering requirements during placement,2% (49/1), 8% (46/4), 20% (40/10) were found for cLMA, I-Gel and Baska Mask, respectively.
Conclusions
As a conclusion, when cLMA, I-Gel and  Baska Mask are compared regarding their placement and ventilating durations, first attempt success rates and required additional maneuvers, cLMA and I-Gel are superior to Baska Mask in urological ambulatory surgical cases. In terms of complications, hemodynamic changes  and adequate ventilation three airway devices were similar.
