Objectives: In this study we compared two ventilation and intubation strategies with regard to their effect on hands-on time: ventilation and intubation with the intubating laryngeal mask airway (ILMA),versus bag mask ventilation (BMV) with tracheal intubation using direct laryngoscopy (DL). Methods: Thirty paramedics and 40 medical students were recruited to perform four standardized CPR manikin scenarios of six minutes each in a random sequence: normal to manage airways using either BMV + DL or the ILMA and difficult to manage airways, again using either BMV + DL or the ILMA. Results The scenarios of 25 paramedics and 36 students were analysed. The time to the first successful ventilation was significantly longer with the ILMA (p < 0.001). Hands-on time was initially lower for the ILMA (p < 0.001), but recovered within the first two minutes and was then significantly greater from minute 3 onward (p < 0.001). First success rate for intubation was higher and the time to ET placement was faster with the ILMA, especially in difficult-to-manage airways (p < 0.001). For difficult-to-manage airways, male participants had a significantly greater hands-on time using BMV + DL, whereas with the ILMA no difference was found between male and female participants. Conclusion: In this manikin-based study, the hands-on time was greater with the ILMA than with BMV + DL. In this setting, the ILMA was particularly useful for ventilation and intubation in difficult-to-manage airways and when used by female participants.
