Brief Summary:
The aim of this clinical trial is to evaluate four supraglottic airway devices for ventilation in a simulated condition of an entrapped trauma patient with simultaneous cervical spine immobilisation All the studied devices are evaluated by fully-qualified and experienced paramedics both male and female The main questions it aims to answer are
1 Which device requires the shortest time required to achieve a successful ventilation
2 What is the first attempt success rate of the studied devices
3 Which device is the easiest to use and the most user-friendly Study participants will evaluate four different supraglottic devices in a restricted access to the entrapped trauma patients airway The maximum number of insertion attempts is limited to three per device

Detailed Description:
A 10-minute lecture will be delivered before the start of the study It will explain how to use the studied devices Following the lecture all participants will be able to familiarise themselves with the equipment and practice for 30 minutes A skill station will be set up containing an intubation manikin AT Kelly Torso Laerdal Medical AS Stavanger Norway A reduced movement of the cervical spine will be achieved by application of a Patriot cervical collar Össur hf Reykjavik Iceland After completion of the initial practice the intubation manikin with the cervical collar on will be placed on and secured to the drivers seat of a medium-sized passenger car FIAT SpA Turin Italy The car will then be positioned on its left side and secured in place by firemen from a local fire brigade The access to the manikin will only be allowed from the front ie through the opening created after removal of the windscreen A single digit number will be allocated to each of the four studied devices ie 1 for the SLIPA device 2 for the I-gel 3 for the LMA Supreme and 4 for the LTS Each study participant will be asked to randomly give a number either 1 2 3 or 4 and will then be given the corresponding airway device to use The maximum number of insertion attempts will be limited to three per device The time required to insert the device and achieve a successful ventilation Tiv will be recorded It will be measured using a stopwatch of a mobile phone Apple Inc Cupertino California USA Efficacy of insertionventilation and the ease of use by the operator will also be assessed The latter will be measured using an 11-point numerical rating scale NRS where 0 corresponds to a very difficult to use device and 10 indicates an easy to use and user-friendly device A manual resuscitator Ambu AS Ballerup Denmark will be used for ventilation and will be readily available to the paramedics The study participants will perform all insertions with each of the four supraglottic airway devices A failed insertion and ventilation is defined as an attempt during which the manikin cannot be ventilated or an attempt that lasted longer than 120 seconds Only those who failed to ventilate will be allowed another attempt All the obtained data will be analysed using Microsoft Office Excel 2021 spreadsheet Microsoft Corporation Redmond WA USA The Kolmogorov-Smirnov test is utilised to determine whether the analysed variables matched the characteristics of a normal distribution A paired Student t-test and the Wilcoxon signed-rank test will be used for data analysis Based on our previous unpublished pilot study and assuming that the overall success rate of intubation in patients with a difficult airway would be 90 α 005 2-sided β 01 46 participants will be required The final adjusted sample size allowing a drop-out rate of about 10 is 50 and this is the final number of participants enrolled into the study A p-value of less than 005 p005 is considered statistically significant
