“…The overall success rate was 97 and 96% for FST and PVC tubes, respectively, but the time taken to perform the intubation and the number of manoeuvres were higher for PVC tubes. A recent study by Shah et al [ 29 ] has also shown similar success rates between FST and PVC tubes through ILMA. While a study by Kundra et al [ 30 ] showed a similar first pass (86%) and overall success rate of intubation (96%) for FST and PVC tubes, Kanazi et al [ 31 ] showed an inferior performance of both Parker tube and PVC tubes through ILMA.…”

Introduction. The study aims to test whether flexible silicone tubes (FST) improve performance and provide similar intubation success through I-Gel as compared to ILMA. Our trial is registered in CTRI and the registration number is “CTRI/2016/06/006997.” Methods. One hundred and twenty ASA status I-II patients scheduled for elective surgical procedures needing tracheal intubation were randomised to endotracheal intubation using FST through either I-Gel or ILMA. In the ILMA group (n = 60), intubation was attempted through ILMA using FST and, in the I-Gel group (n = 60), FST was inserted through I-Gel airway. Results. Successful intubation was achieved in 36.67% (95% CI 24.48%–48.86%) on first attempt through I-Gel (n = 22/60) compared to 68.33% (95% CI 56.56%–80.1%) in ILMA (n = 41/60) (p = 0.001). The overall intubation success rate was also lower with I-Gel group [58.3% (95% CI 45.82%–70.78%); n = 35] compared to ILMA [90% (95% CI 82.41%–97.59%); n = 54] (p < 0.001). The number of attempts, ease of intubation, and time to intubation were longer with I-Gel compared to ILMA. There were no differences in the other secondary outcomes. Conclusion. The first pass success rate and overall success of FST through an I-Gel airway were inferior to those of ILMA.

“…This may be due to use of a specific tube for LMA Fastrach that is wire-reinforced, and a soft-tip PVC tube is not standard. We considered that the use of a non-flexible PVC tube prolonged the tube passing time for LMA Fastrach in our study [ 13 , 14 ].…”

ObjectiveThis study aimed to compare intubation performance between blind intubation through supraglottic airway devices and direct laryngoscopy by novices under manikin simulation. We hypothesized that the intubation time by novices using supraglottic airway devices was superior to that with the Macintosh laryngoscope (MCL).MethodsA prospective, randomized crossover study was conducted with 95 participants, to evaluate i-gel, air-Q, LMA Fastrach, and MCL devices. Primary outcomes were the intubation time and the success rate for intubation.ResultsThe i-gel showed the shortest insertion and tube passing time among the four devices; the i-gel and air-Q also showed the shortest total intubation time (all P<0.0083; i-gel vs. air-Q, P=0.03). The i-gel and MCL showed the highest cumulative success rate (all P<0.0083; i-gel vs. MCL, P=0.12).ConclusionBlind intubation through the i-gel showed almost equal intubation performance compared to direct laryngoscopy.

“…In this study, we compared the efficacy of the PVC tube compared with that of the WRS tube in IGI and IBRI. The WRS tube can be more advantageous than the PVC tube, because the WRS tube is more flexible and noncompressible during the passage through i-gel [13, 20]. Nevertheless, the reinforced tube is expensive and less readily available compared with the PVC tube [17, 21].…”

“…We thought it might result in an increase of hands-off time and decrease of ETI accuracy. So, we assume that the use of wire-reinforced silicone (WRS) tube instead of PVC tube could overcome this problem [13].…”

Purpose This study aimed to compare intubation performances among i-gel blind intubation (IGI), i-gel bronchoscopic intubation (IBRI), and intubation using Macintosh laryngoscope (MCL) applying two kinds of endotracheal tube during chest compressions. We hypothesized that IGI using wire-reinforced silicone (WRS) tube could achieve endotracheal intubation most rapidly and successfully. Methods In 23 emergency physicians, a prospective randomized crossover manikin study was conducted to examine the three intubation techniques using two kinds of endotracheal tubes. The primary outcome was the intubation time. The secondary outcome was the cumulative success rate for each intubation technique. A significant difference was considered when identifying p < 0.05 between two devices or p < 0.017 in post hoc analysis of the comparison among three devices. Results The mean intubation time using IGI was shorter (p < 0.017) than that of using IBRI and MCL in both endotracheal tubes (17.6 vs. 29.3 vs. 20.2 in conventional polyvinyl chloride (PVC) tube; 14.6 vs. 27.4 vs. 19.9 in WRS tube; sec). There were no significant (p < 0.05) differences between PVC and WRS tubes for each intubation technique. The intubation time to reach 100% cumulative success rate was also shorter in IGI (p < 0.017) than that in IBRI and MCL in both PVC and WRS tubes. Conclusions IGI was an equally successful and faster technique compared with IBRI or MCL regardless of the use of PVC or WRS tube. IGI might be an appropriate technique for emergent intubation by experienced intubators during chest compressions.
