Purpose : This study was designed to compare the easiness and speed of insertion of three supraglottic airway devices(SADs) in a manikin setting.
Methods : Three different SADs - Laryngeal Mask Classic(cLMA), I-gel and Streamlined Liner of the Pharynx Airway(SLIPA) were applied. One hundred and nineteen paramedical students with(group H) or without (group L) previous airway experience were taught brief manikin training about the use of the cLMA, I-gel and SLIPA. The students inserted each device in a randomized order. Time to effective ventilation was recorded in seconds from holding the device to the first chest inflation. Success was determined as adequate chest wall movement.
Results : The insertion attempts were lesser in I-gel(1.00±0.00) and SLIPA(1.05±0.27) than cLMA(1.16±0.41, p<.05). The shortest time to insertion was recorded for I-gel(10.5±3.0 sec), followed by the SLIPA(12.9±4.5 sec) and cLMA(19.6±4.1 sec, p<.05). There were no significant differences in the insertion attempts and insertion time of I-gel between group L and group H. But in cLMA, longer insertion time and more insertion attempts were recorded in group L than group H.
Conclusion : Both I-gel and SLIPA were superior to cLMA in the easiness and speed of insertion. Even in novice students, I-gel showed an excellent result in a manikin.
