Background: Airway management in patients with out of hospital cardiac arrest (OHCA) is important and several methods are used. The establishment of a supraglottic airway device (SAD) is a common technique used during OHCA. Two types of SAD are routinely used in Norway; the Kings LTS-D™ and the I-gel®. The aim of this study was to compare the clinical performance of these two devices in terms of difficulty and number of attempts before successful insertion.
Methods: All adult patients with OHCA, in whom ambulance personnel used a SAD over a one-year period in the ambulance services of Central Norway, were included. After the event, a questionnaire was completed and the personnel responsible for the airway management were interviewed. Primary outcomes were number of attempts until successful placement of SAD and graded difficulty of insertion. Secondary outcomes were specified challenges with the SAD at insertion. Intergroup differences were compared using Chi-square test for multiple groups.
Results: Two hundred and fifty patients were included, of whom 191 received I-gel and 59 received LTS-D. Overall success rate was significantly higher in I-gel (86 %) compared to LTS-D (75%, p = 0,043). The difficulties of insertion were significantly lower among patients receiving I-gel (easy 80 %, medium 13 % and difficult 7 %) compared to LTS-D (easy 51 %, medium 22 % and difficult 27 %, p < 0,001).
Conclusions: Overall success rate was significantly higher and the difficulty in insertion was significantly lower in the I-gel group compared to the LTS-D in patients with OHCA.
