Insertion under laryngoscopic guidance has been used to achieve ideal positioning of the laryngeal mask airway (LMA). However, date, efficacy this technique evaluated only using fiberoptic evaluation, and results have conflicting. Other reliable tests evaluate not established. Recently, it suggested that accuracy LMA placement can be determined by clinical signs such as oropharyngeal leak pressure (OPLP). The aim study was assess insertion OPLP an indicator. After approved institutional ethics committee, a prospective comparison 100 patients divided into 2 groups (50 with blind 50 laryngoscope technique) were evaluated. An (LarySeal™, Flexicare medical Ltd., UK) inserted approach in group laryngoscopy laryngoscope-guided group. OPLP, position score, whether first attempt at successful, time taken for insertion, ease adverse events recorded. Data presented mean ± standard deviation. higher than (21.4 8.6 cmH2O vs. 18.1 6.1 cmH2O, p = 0.031). rate success attempt, pharyngolaryngeal similar between both groups. significantly longer group, compared (35.9 9.5 s 28.7 s, < 0.0001). Laryngoscope-guided improves seal insertion. Our result suggests may useful cris.nih.go.kr , identifier: KCT0001945 (2016-06-17).
