“…17 Also, our study did not assess insertion time or the skill required to place the devices, considerations that may affect the safety of the devices. 18 In conclusion, all devices sealed the esophagus effectively to at least 40 cm H 2 O, indicating that they should be safe during routine use in the operation room. The Combitube, Easytube, and Intubating LMA showed the best seal with a closed esophageal drainage lumen.…”

“…12 As the time to ventilation is shorter when using supraglottic airway devices, 13,14 particularly in difficult cases, 15 it seems reasonable to perform a prospective trial comparing the placement of supraglottic devices to that of conventional endotracheal tubes, investigating the time needed for interrupting heart massage during CPR, and recognizing that airway management does not alter outcomes in patients in cardiac arrest.…”

Objectives: Endotracheal intubation (ETI) is considered the gold standard for protecting the airway. Alternative devices for airway protection have been developed that can be used by untrained personnel, by those with less experience, and for when ETI is not possible. The main goals of our study were to evaluate the success rate and speed of insertion of different supraglottic airway devices and to determine whether the devices could be properly inserted under simulated critical conditions. Methods: Fifty medical students used an airway simulation trainer (Laerdal SimMan 3G) to assess the success rate and time used to insert seven different supraglottic airway devices under simulated physiologic and pathologic conditions in two different runs. Results: Although all airway devices could be inserted without problems, only the Combitube and the EasyTube could be successfully inserted in simulations of trismus, limited mobility of the cervical spine, or a combination of pathologic conditions such as trismus plus limited mobility of the spine and trismus plus tongue edema. The insertion time was significantly longer with LMA Unique, Fastrach, and I-Gel devices in both the first and second runs. Conclusion: The Combitube and the EasyTube were most easily inserted under simulated conditions such as trismus, limited mobility of the cervical spine, and combined pathologic conditions. Although all devices are useful for establishing an airway by nontrained medical students in standard simulations, we suggest that the Combitube and the EasyTube may offer advantages in difficult airway situations. RÉ SUMÉObjectifs: Le tube endotraché al est considé ré comme le moyen par excellence de protection des voies aé riennes. Cependant, il existe d'autres dispositifs de protection des voies aé riennes qui peuvent ê tre utilisé s par du personnel non formé ou des personnes ayant peu d'expé rience ou encore dans des cas où l'intubation endotraché ale n'est pas possible. L'é tude avait pour buts principaux d'é valuer le taux de ré ussite de la mise en place et le temps de pose de diffé rents dispositifs supraglottiques et de dé terminer si ces dispositifs pouvaient ê tre installé s correctement dans des situations d'urgence simulé es. Mé thodes: Cinquante é tudiants en mé decine ont utilisé un simulateur de voies aé riennes (Laerdal SimMan 3G) pour é valuer le taux de ré ussite de la mise en place et le temps de pose de sept dispositifs supraglottiques diffé rents, dans des é tats physiologiques et pathologiques simulé s, en deux sé ances. Ré sultats: Il a é té possible de poser tous les dispositifs sans problè me, mais seuls les tubes Combitube et EasyTube ont pu ê tre mis en place dans des é tats simulé s de trismus, de mobilité ré duite de la colonne cervicale, ou d'association d'é tats pathologiques tels que le trismus et une mobilité ré duite de la colonne cervicale ou le trismus et un oedè me de la langue. Le temps de mise en place d'autres dispositifs: le LMA Unique, le Fastrach, et l'I-Gel, é tait passablement plus long,...

“…[14,15] The i-gel is considered easier to insert due to its unique gel like thermo plastic material, shape and contour, buccal stabilizer and epiglottis blocker which minimises epiglottis down folding. Furthermore, the studies from the past indicate a near similar insertion time between PLMA and CT. [10][11][12]16] In our study, we report mean insertin time of CT being significantly lower than i-gel and PLMA. This may be because CT has a unique profile and requires little or no manipulation at all for insertion into oropharynx.…”

“…The first attempt insertion success achieved in our study was comparable to data from multiple studies. [7][8][9][10][11][12] The ease of insertion was similar for all the devices. However, the i-gel showed a higher probability of insertion success without resistance than the PLMA and CT of all the successful insertions which may be partly explained by the non inflatable cuff in the i-gel.…”
