The placement of four different supraglottic airway devices by medical students: a manikin study

Although endotracheal intubation is the gold standard in airway management, this procedure requires both technical training and experience. Supraglottic airway devices are an alternative to endotracheal intubation and are simpler, less invazive, and require less time for placement compared with endotrakeal intubation. Aim of the study was to evaluate the success rates, ease of use, duration of application, and maneuver performance of different supraglottic airway devices (SADs) used by term-5 medical students on a manikin.

This cross-sectional study was conducted in Zonguldak Bülent Ecevit University Hospital, Turkey, between April and June 2022. Term 5 Medical students (n = 111) were asked to place four different SAD [classical laryngeal mask, suprema laryngeal mask, ProSeal laryngeal mask (pLMA), I-gel] on an adult airway manikin. After the students were trained in the use of the devices, the ease of use for each, duration of successful application, success of application and use of optimization maneuvers were recorded. The participants were asked to distinguish the device they felt most confident to place and the most difficult to implement.

There was a significant difference between the groups in ease and duration of application (p < 0.001). The most difficult and longest application time was with pLMA and the easiest and shortest was with I-gel (p < 0.05). The number of application failure was also highest for pLMA (p < 0.001). It was found that the participants distinguished (41%) I-gel as the most confident device to use, (84%) pLMA as the most difficult device to use for airway control.

I-gel was found to be superior to others in terms of ease of use, duration and success of application.
