Randomized Controlled Trial Comparative Study
Comparison of the clinical performance of i-gel, LMA Supreme and LMA ProSeal in elective surgery.
The LMA Supreme™, i-gel® and LMA ProSeal™ are second-generation supraglottic airway devices. We tested the hypothesis that these devices differ in performance when used for spontaneous ventilation during anaesthesia. ⋯ The three devices were comparable in terms of ease and duration of placement, but the i-gel had higher initial oropharyngeal leak pressure and lower airway morbidity compared with the ProSeal and Supreme.
