Are nurses able to perform blind intubation? Randomized comparison of I-gel and laryngeal mask airway

Ladny JR, Bielski K, Szarpak L, Cieciel M, Konski R, Smereka J. Am J Emerg Med. 2017 May; 35(5): 786-787

Manikin study to assess effectiveness of blind intubation through the i-gel, LMA Classic and a standard cuffed tracheal tube, performed by 34 nurses in CPR conditions across two scenarios (with and without chest compressions). Primary measure was time to intubation. i-gel recorded a lower median time to intubation and higher, statistically significant, successful insertion rates in both scenarios. Performing compressions doesn't significantly affect time to perform blind intubation in this setting, but reduces the effectiveness of first intubation attempt. i-gel was faster in both scenarios.

Tracheal intubation through I-gel performed during simulated cardiopulmonary resuscitation

Wojewodzka-Zelezniakowicz M, Majer J. Am J Emerg Med. 2017 Jan 16.

Manikin study to compare the efficacy of ETI performed by 27 nurses using the i-gel as a guide with/without chest compressions. Results showed that in this scenario, nurses were able to perform blind intubation using the i-gel with 'high efficiency'.

Performance of intubation with 4 different airway devices by unskilled rescuers: manikin study

Lee DW, Kang MJ, Kim YH, Lee JH, Cho KW, Kim YW, Cho JH, Kim YS, Hong CK, Hwang SY. Am J Emerg Med. 2015 May;33(5):691-6

LMA Classic, i-gel, PENTAX Airway Scope and Macintosh laryngoscope were all tested, with time to ventilation, intubation success rate and difficulty of intubation measured. Authors conclude that intubation with i-gel was faster and easier.

Simulation analysis of three intubating supraglottic devices during infant chest compression

Kohama H, Komasawa N, Ueki R, Kaminoh Y, Nishi S. Pediatr Int. 2015;57(1):180-2

Study on performance of air-Q, Ambu Aura-i and i-gel in a manikin simulation, undertaken by 22 novice physicians. Rate of success and insertion time with and without chest compressions were measured.

Evaluation of chest compression effect on airway management with air-Q, aura-i, i-gel, and Fastrack intubating supraglottic devices by novice physicians: a randomized crossover simulation study

Komasawa N, Ueki R, Kaminoh Y, Nishi S. J Anesth. 2014 Oct;28(5):676-80

Insertion time and successful ventilation rate were measured, with the latter unaffected by chest compression.
