Comparison of fiberoptic-guided success of intubation using intubating LMA and intubating laryngeal tube suction

Background and Aims: The present study aimed to compare the success rate of fiberoptic-guided intubation, using Intubating laryngeal mask airway (ILMA) versus intubating laryngeal tube suction disposable (ILTS-D). Material and Methods: This prospective randomized study was conducted on 100 patients of either sex aged 18–60 years, belonging to the American Society of Anesthesiologists physical status I–II, with 50 patients in each group (group I –patients were intubated through ILMA, and group II – patients were intubated through ILTS-D). The primary objective was to compare the ease of fiberoptic-guided tracheal intubation, time taken for intubation, and number of attempts. Secondary objectives included assessing the success of supraglottic device (SAD) placement, oropharyngeal seal pressure, and hemodynamic changes, and adverse effects like sore throat, trauma, nausea, etc. Results: The insertion time of the SAD was 10.44 ± 4.26 and 9.08 ± 3.79 s for groups I and II, respectively. Mean insertion time for ETT (Endotracheal tube) placement (seconds) was 39.68 ± 9.48 s in group I and 50.12 ± 7.78 s in group II, which was found to be statistically significant between the groups ( P ≤ 0.001). The ETT was placed in the first attempt in 78% and 44% patients in group I and group II, respectively ( P = 0.001). Conclusion: Our study concluded that ILMA demonstrated superiority over ILTS-D when used as conduits for fiberoptic-guided tracheal intubation.
