A comparison of various supraglottic airway devices for fiberoptical guided tracheal intubation

Abstract

None of the used supraglottic airway devices offered a full or partial glottic view in all cases. However the Laryngeal Mask Airway Unique and the Laryngeal Mask Airway Aura-once seem to be more suitable for fiberoptical assisted intubation compared to other devices.

Supraglottic airway devices in short gynecological procedures: A randomized, clinical study comparing the Baska® mask and I-Gel® device

“…The precise positioning of Baska ® mask is essential against the larynx as the cuff opening is smaller for the mask for ventilation. [13] The leak pressure of about 45 cm H 2 O suggests the presence of a good airway seal using Baska ® mask. The patient comfort indices were reassuring with the use of Baska ® mask and the same have been described in earlier studies.…”

Formulating a good research question: Pearls and pitfalls

“…Despite that the study was aimed to explore the ease of intubation in patients with anticipated difficult airway (thus requiring fibreoptic tracheal intubation), authors decided to enrol patients undergoing elective laser treatment for genital condylomas, as a strategy to hasten the recruitment process and optimise resources. [15]…”

“…Multiple comparisons should be generally avoided, unless there is enough statistical power to address the end points of interest, and statistical analyses have been adjusted for multiple testing. For instance, in the aforementioned study of Metterlein et al .,[15] authors compared five supraglottic airway devices by recruiting only 10--12 participants per group. In spite of the authors' recommendation of using two supraglottic devices based on the results of the study, there was no mention of statistical adjustments for multiple comparisons, and given the small sample size, larger clinical trials will undoubtedly be needed to confirm or refute these findings.…”

A left-side channel design improving insertion of gastric tube via the supraglottic airway device

“…[2] Such a design may cause some difficulty for insertion of the gastric tube if there is an inadequate position of the device tip in the upper esophageal aperture. [3] In normal anatomy, the upper esophageal aperture is actually inclined to the left side of the trachea. [4] Thus, we inferred that it should be much easier to insert a gastric tube into the esophagus, if the gastric drainage channel is placed at the left side of the SAD tip.…”
